Answer:
.4521
Step-by-step explanation:
when converting a percentage to a decimal you have to move the decimal point over two times to the left. do if you have 100% you moved the decimal point over two and get 1.00
Answer:
0.4521
Step-by-step explanation:
Instead, you can simply multiply a number by 45.21 as a decimal to get the answer.
45.21 percent means 45.21 per hundred. Therefore, to get 45.21 as a decimal, all you have to do is divide 45.21 by 100 like so:
45.21 ÷ 100 = 0.4521
Shortcut: When you divide anything by 100, just move the decimal point two places to the left.
Normally, to calculate 45.21 percent, you would multiply a number by 45.21 percent and then you would take the product of that and divide it by 100 to get the answer.

What are coordinates?
A pair of numbers that use the separations between the two reference axes to define the location of a point on a coordinate plane. usually represented by the x- and y-values, respectively, (x, y).
The position of a point or a shape in a given space is determined by coordinates, which are numbers (a map or a graph ).
x - coordinate = 5 grid lines to the right of the y-axis
y - coordinate = 3 grid lines below the x-axis.
The point A is in the 4th quadrant
(x,y) = ( + 5 grid lines, -3 grid lines )
There are increments I have one over four for each grid line on each of the two axes
This means,
(x,y) = ( + 5 * 1/4, -3*1/4 ) = ( 5/4, -3/4)
So, the coordinates of point A are ( 5/4, -3/4)

14. Damian is building a display case to hold
75 model cars. The case will have fewer
than 10 shelves, and each shelf will hold
no more than 15 cars. If Damian wants
each shelf to have the same number of
cars, how many shelves should he put in
the display case?
Damian should put 5 shelves in the display case to hold 75 model cars and ensure that each shelf has the same number of cars.
What is the unit value?
Unit value is a measure of the price of a single unit of a good or service. It is calculated by dividing the total cost of the good or service by the number of units purchased. It is also known as unit cost.
To determine how many shelves Damian should put in the display case, we can use the following steps:
Divide the total number of cars by the maximum number of cars per shelf. In this case, 75 model cars / 15 cars per shelf = 5
If the number of shelves is not a whole number, round up to the next whole number. In this case, 5 shelves is already a whole number, so we don't need to round up.
Check that the number of shelves is less than 10. In this case, 5 shelves are less than 10 shelves.
Hence, Damian should put 5 shelves in the display case to hold 75 model cars and ensure that each shelf has the same number of cars.

The function f is defined on the closed interval [-5,4]. The graph of f consists of three line segments and is above in the figure above. Let g be the function defined by g(x) = integral_2_-3 f(t) dt. a. Find g(3) b. On what open intervals contained in -5 lessthan x lessthan 4 is the graph of g both increasing and concave down? c. The function h is defined by h(x) = g(x)/5x. Find h'(3). d. The function p it defined by p(x) = f(x^2 - x). Find the slope of the line tangent to the graph of p at the point where x = -1.
a. g(3) = -2
b. g is increasing and concave down on the intervals (-3 <= x < 2) and (2 <= x <= 4).
c. h'(3) = 0
d. The slope of the tangent line to the graph of p at x = -1 is -3.
a. The function g is defined as the definite integral of f(t) with respect to t from -3 to 2. Therefore, g(3) = integral_2^3 f(t) dt. From the graph, we can see that:
f(t) = 2 for -5 <= t < -3f(t) = -t for -3 <= t < 2f(t) = 2t - 8 for 2 <= t <= 4.Therefore, g(3) = integral_2^3 (-t) dt + integral_2^3 (2t - 8) dt
= -1/2(3^2 - 2^2) + 1/2(3^2 - 2^2 - 8(3 - 2)) = -5/2 + 1/2 = -2.
b. The graph of g is increasing and concave down when the graph of f is concave down and when the definite integral of f is increasing. From the graph of f, we can see that f is concave down on the intervals (-5 <= t < -3) and (2 <= t <= 4). Therefore, g is increasing and concave down on the intervals (-3 <= x < 2) and (2 <= x <= 4).
c. The function h is defined by h(x) = g(x)/5x. To find h'(3), we need to use the quotient rule for derivatives. h'(x) = (5xg'(x) - g(x)5)/5x^2.
Since g(x) = integral_2_-3 f(t) dt, it is not a function of x, so g'(x) = 0. Therefore, h'(3) = (530 - 05)/53^2 = 0.
d. The function p is defined by p(x) = f(x^2 - x). To find the slope of the line tangent to the graph of p at the point where x = -1, we need to find the derivative of p at -1. Using chain rule: p'(x) = f'(x^2-x)(2x-1) so p'(-1) = f'(-1) * (2(-1)-1) = (2(-1) -1) = -3.
Therefore, the slope of the tangent line to the graph of p at x = -1 is -3.

In this activity, you are investigating the financial viability of the martingale betting strategy that was introduced in class.
Recall how a martingale works. You place a bet on any "even money" event (that is, a wager where winning means gaining the money bet). If you win, you stop — you have won money. If you lose, you keep doubling the bet until you win, and then stop. Your winnings will cover the previous losses. Unfortunately, a long losing streak means that you run out of money and can no longer bet – hence losing a lot.
Balph Snerdwell has $31 in his wallet. He is going to be betting on red or black, at the roulette table. Recall that, in an American casino, there are 38 numbers — 18 red and 18 black (plus 0 and 00). So Balph has an 18/38 probability of winning, each time he bets.
a) Balph plays a martingale — doubling his bet after each loss. What’s the maximum number of times he can lose? Why?
b) Recall that Balph might win a dollar from playing a martingale … or he might lose all $31 in his wallet. What’s the probability that he wins a dollar? That he loses everything?
c) And so, what is the expected value of Balph’s net winnings, from one martingale?
d) Sometimes Balph will bet only one dollar. But sometimes he will bet three dollars (if he loses, then wins). Or seven dollars (lose, lose, win). Or some other amount. What are the possible values for total amount wagered? Their probabilities? Therefore, what is the expected value of the numbers of dollars wagered?
e) In Part D you found how much money Balph won, on average. In Part E, you found how much money Balph bet, on average. How much did Balph win, per dollar bet? (Does this number look familiar?)
The answers are:
b) 0.9596, 0.0404
c) expected value of dollars won = -$0.29236
d) expected value of dollars wagered = $5.55475
Can someone please break it down and explain how they got the answers
Answer:
a) Balph can lose a maximum of 6 times in a row before running out of money and not being able to place any more bets. This is because if he loses 6 times in a row, he would have to bet $64 (1+2+4+8+16+32) which is more than the $31 he has in his wallet.
b) The probability that Balph wins a dollar is 0.9596 and the probability that he loses everything is 0.0404. These probabilities are calculated by assuming a 18/38 probability of winning each bet and using the martingale betting strategy.
c) The expected value of Balph's net winnings from one martingale is -$0.29236. This means that on average, Balph can expect to lose $0.29236 each time he plays the martingale betting strategy.
d) The possible values for the total amount wagered are $1, $3, $7, $15, $31, and $64. These values correspond to the amount wagered after losing 0, 1, 2, 3, 4 and 5 times in a row. The probability of each value depends on the probability of losing that many times in a row, calculated using the 18/38 probability of winning each bet. The expected value of the number of dollars wagered is $5.55475.
e) The amount Balph wins per dollar bet is -0.0527. This number is calculated by dividing the expected value of Balph's net winnings by the expected value of the number of dollars wagered. This number is less than zero, indicating that on average, Balph will lose money for every dollar he bets.

A copper pipe has an inside diameter of 3.00 cm and an outside diameter of 5.00 cm (see the figure(Figure 1)) - Part A What is the resistance of 19.0 m of this pipe?
The resistance of 19.0m of the given copper pipe is 1.19 x [tex]10^{-6}[/tex] ohm.
The resistance of a pipe is given by the formula:
R = (p * L) / (A * n)
where R is the resistance, p is the resistivity of the material (in this case, copper), L is the length of the pipe, A is the cross-sectional area of the pipe, and n is the number of conductors (in this case, 1).
To find the cross-sectional area of the pipe, we first need to find the radius of the pipe. We can do this by taking the difference between the outside diameter and the inside diameter and dividing by 2:
r = (d_outside - d_inside) / 2
r = (5.00 cm - 3.00 cm) / 2
r = 1.00 cm
Now we can find the cross-sectional area of the pipe:
A = pi * [tex]r^2[/tex]
A = pi * [tex](1.00 cm)^2[/tex]
A = 3.14
Next, we can use the resistivity of copper, which is 1.68 x[tex]10^{-8}[/tex] ohm-cm. Now we have all the values required to find the resistance of the pipe:
R = (p * L) / (A * n)
R = (1.68 x [tex]10^{-8}[/tex] ohm-cm * 19.0 m) / (3.14 [tex]cm^2[/tex] * 1)
R = (1.68 x [tex]10^{-8}[/tex] ohm-cm * 19.0 m) / (3.14 [tex]cm^2[/tex])
R= 1.19 * [tex]10^{-6}[/tex] ohm
Therefore, the resistance of 19.0m of this pipe is 1.19 x [tex]10^{-6}[/tex] ohm.

When asked which of the following is true in this situation, "if a distribution has zero variants," the response is "D."
Due to the variance's definition, which is the same for both continuous and discrete random variables, all of the values must be equal to one another. For all possible values of X, the variance is determined by measuring the excess distance from the mean.
If any one of these individual values deviates from the mean, it follows that the variations must also deviate from zero because the integration will result in the difference squared being represented as a positive number.

Trisha is twice as old as Mina. 10nyears from now, Trisha will be 4 years older than Mina. How old is Trisha and Mina?
Answer: Let's say Trisha is currently T years old and Mina is currently M years old.
We know from the problem statement that Trisha is twice as old as Mina:
T = 2M
We also know that 10 years from now, Trisha will be 4 years older than Mina:
T + 10 = M + 4
We can substitute the first equation into the second equation:
2M + 10 = M + 4
We can then solve for M:
M = 6
So, Mina is currently 6 years old.
We can use the first equation to find Trisha's current age:
T = 2M = 2 * 6 = 12
Therefore, Trisha is currently 12 years old and Mina is currently 6 years old.

The linear function to find average cost will be A=$(2.25+0.079t), average cost of a comic book in 2020 = $4.3, Average cost will be $5 in year 2029.
what is a linear function?
A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra. The only difference is the function notation. Knowing an ordered pair written in function notation is necessary too. f(a) is called a function, where a is an independent variable in which the function is dependent. Linear Function Graph has a straight line whose expression or formula is given by;
y = f(x) = px + q
It has one independent and one dependent variable. The independent variable is x and the dependent one is y. P is the constant term or the y-intercept and is also the value of the dependent variable. When x = 0, q is the coefficient of the independent variable known as slope which gives the rate of change of the dependent variable.
Now
Initial value = $2.25 in 1994
cost in 2016 = $3.99
Therefore
3.99=2.25+2.25*r*22/100
r=0.079
where r=rate
then
Average cost=initial value+0.079t
Hence
A=$(2.25+0.079t)
where t=time (given year - 1994)
cost in 2020=$(2.25+0.079*26)
cost in 2020=$4.3
Now for A=$5
5=2.25+0.079t
t=35years
Hence Average cost will be $5 in year 2029.

please help! Kendra and Theo each collected data on the number of birds observed at a bird feeder each hour for eight hours.
Remaining two data of Theo's observation is 9 and 11.
What is mean, median and range in a data list?
Mean is the average of all data value. Range is the difference between the highest and lowest value of a data set. Median implies the middle value of a data set. If the number of data is even than median is calculated from average of two middle value. If the number of data is odd, then the median is the middle of all data.
What is the two-missing data for Theo's bird observation?
given, Kendra and Theo both collected data of bird observation.
Kendra data's summary are as following.
range = 6
median = 7
mean = 7
From the Theo's data
range = 6
median = 7
mean = 7.5
the question shows 6 data among the total 8 data of Theo's observation.
5,5,6,6,8,10 are 6 data of total 8 data.
let, the missing value are X and Y.
we know mean of a data list is calculated by adding all the value and divided the sum by total amount of data.
mean = 7.5 = (X + Y + 5+ 5+ 6+ 6+ 8+10) / 8
X + Y + 40 = 60
X+Y = 20
we know range is the difference between the highest and the lowest number of a data set.
let, the highest number is X and lowest number is assumed 5.
As range is 6, range = X - 5
X- 5 = 6
X = 11
highest number of data set = 11
now we get the other missing data from the equation, X + Y = 20
Y = 20 -11
Y = 9
now, the data set can be arranged as
5,5,6,6, 8,9, 10,11
we notice that the two middle value is 6 and 8.
median = (6+8) / 2 = 7
that is equal to given median by Theo.
hence, the determination is verified.

Which of the following is an example of a variable measured at the nominal level of measurement?
A. Location in which respondent was born
B. Religiosity measured as not religious, somewhat religious, and very religious
C. Time in seconds in which a subject completes a given task D. Number of respondents' first cousins
E. Level of education in years completed
Religion is an example of a variable measured at the nominal level of measurement. Thus, option B is correct.
Nominal values are those that cannot be quantified by numbers, such as when calculating age or tallying academic accomplishments. As opposed to the ordinal, interval, or ratio measurements, it is the level of measurement representing a variable that just has distinct properties.
Since the 'characteristic' or 'identity' we are interested in is just named, the nominal level of measurement is the least accurate and illuminating. In nominal variables, the numerical values just "label" the attribute in a distinctive way. The numerical value is just a label in this instance.

What does the term function mean?Numbers and their variants, equations & related structures, and geometry and their regions and potential applications are all mathematical topics. The link between a group of input, each of which generates a related output, is referred to as a "function." A function is a relationship between outputs and inputs where each input results in a single, distinct output. Each procedure has a domain and a city / municipality, which are frequently referred to as a scope. Functions are usually represented by the letter f. (x). The input is X. On activity, one-to-one activities, many-to-one activities, throughout operations, as well as on functions are the four main categories of supplied functions.
