Jan doubled her starting number, added 5, subtract 7, divided by 3, then squared the result. If her final answer was 36, what was her starting number?
(Answer due at 12:00 pm PDT)
Answer: I think its 39
Step-by-step explanation: I did the math
Jan's starting number was 10.
What are Numbers?A number is an arithmetic value used for representing the quantity and used in making calculations.
Given that Jan doubled her starting number, added 5, subtract 7, divided by 3, then squared the result.
Let her original number be x
Therefore, {(2x +5 - 7)/3}² = 36
{(2x -2)/3}² = 36
(2x -2)/3 = 6
2x - 2 = 18
2x = 20
x = 10
Hence, Jan's starting number was 10.

20. Favorite Cookie Ten percent of adults say oatmeal raisin is their favorite
cookie. You randomly select 12 adults and ask them to name their favorite
cookie. Find the probability that the number who say oatmeal raisin is their
favorite cookie is (a) exactly four, (b) at least four, and (c) less than four.
(Source: WEAREVER)
Answer:
Step-by-step explanation:
A
exactly 4
There are 12 adults.
4 like oatmeal cookies the best.
P(exactly 4) = 4/12 = 1/3 = 0.3333...
B)
At least 4
4 5 6 7 8 9 10 11 12
So there are 9 choices (4 .. 12) of those who could like oatmeal cookies the best.
P(9) = 9/12 = 0.75
C)
1 2 3
There are at most 3 people who could like oatmeal cookies the best.
P(<4) = 3/12 = 0.25
Less than 4 who would choose oatmeal cookies = 1/4
If 81 is added to a number, the result is 39 less than three times the number. Find the number.
Answer:
60
Step-by-step explanation:
The number is represented as x.
81 is added to a number is
81 + x
39 less than three times the number
3x - 39
So
81 + x = 3x - 39
Solve for x.
81 + x = 3x - 39 Add 39 to each side so 39 cancels on the right.
81 + x + 39 = 3x - 39 + 39
81 + x + 39 = 3x
81 + 39 + x = 3x
120 + x = 3x Subtract x from each side.
120 + x - x = 3x - x
120 = 3x - x
120 = 2x Divide each side by 2
120/2 = 2x/2
120/2 = x
60 = x
Is this a fair or biased sample.
A store owner wants to survey customers about the products he sells. He programs the computer to select 100 customers from the mailing list and sends them each a survey.
(I'm torn on this one because on one hand, he's only selecting customers from his mailing list which makes me think biased, on the other he is using the computer to randomly select them so that seems fair. Also, of the people who are sent the surveys, everyone may not apply. So I'm leaning towards biased.)
Answer:
biased
Step-by-step explanation:
even with the computer randomly picking people, they are still all on the mailing list.
What is the value of y if the line through the two given points is to have the indicated slope (4,y) and (2,6), M=-4?
Answer:
y= -2
Step-by-step explanation:
y2-y1 6-y = 8
x2-x1 2-4= -2
To solve for y : Your answer has to be 8 then you divide 8/-2 = -4
6-y=8
subtract 6 from both sides = -y =2
multiply each side by(-1)
to remove the - from Y (-1)y =(-1)2

at a 911 call center, calls come in at an average rate of one call every two minutes. assume that the time that elapses from one call to the next has the exponential distribution. Find the probability after a call is received, it takes more than 3 minutes for the next call to occur.
Using the exponential distribution, it is found that there is a 0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.
What is the exponential distribution?The exponential probability distribution, with mean m, is described by the following equation:
[tex]f(x) = \mu e^{-\mu x}[/tex]
In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.
The probability of finding a value higher than x is:
[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]
In this problem, the mean is of two minutes, hence the decay parameter is given by:
[tex]\mu = \frac{1}{2} = 0.5[/tex]
The probability that it takes more than 3 minutes for the next call to occur is given by:
[tex]P(X > 3) = e^{-0.5 \times 3} = 0.2231[/tex]
0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.

hits. Sanchez had enter your response here
hits.
Answer:
denote the number of hits that sanchez had with since washington had 18 more hits than sanchez we can say that washington had + 18 hits.
since the total number of hits is 308 we can write
+ ( + 18) = 308.
This is an equation for finding .
2 + 18 = 308
2 = 290
= 145.
so sanchez had 145 hits.
to find the number of hits by washington add 18:
+ 18 = 145 + 18 = 163.
Answer: sanchez had 145 hits and washington had 163 hits.

Answer:
Step-by-step explanation
There are many ways to prove this identity. But, I will use the simplest one. If you have a right triangle, the length of the horizontal side is x, the length of the vertical side is y, and the hypotenuse is r. So, the relation between x and r can be written in cosine form:
[tex]\cos\theta=\frac{x}{r}[/tex]
The relation between y and r can be written in sine form:
[tex]\sin\theta=\frac{y}{r}[/tex]
Pythagoras told you that for the right triangle [tex]x^{2}+y^{2}=r^{2}[/tex] should be satisfied. Substitute x and y from the cosine and sine form:
[tex](r\cos\theta)^{2}+(r\sin\theta)^{2}=r^{2}[/tex]
[tex]r^{2}\cos^{2}\theta+r^{2}\sin^{2}\theta =r^{2}[/tex]
the square of r will cancel out, and you can get your identity:
[tex]\cos^{2}\theta+\sin^{2}\theta=1[/tex]

Alvin is 15 years younger than Elga. The sum of their ages is 45. What is Elga's age?
Answer:
Elga is 30 and Alvin is 15
Step-by-step explanation:
45-15=30
30-15=15
30+15=45
Answer:
[tex]\huge\boxed{\text{Alvin = 15, Elga = 30}}[/tex]
Step-by-step explanation:
In order to find Alvin and Elgas age, we can use a system of equations.
Let us assume that [tex]a[/tex] represents Alvin's age and [tex]e[/tex] represents Elgas age.
We can create two equations:
[tex]a = e-15[/tex]
[tex]a+e=45[/tex]
We can now use substitution to find each value. Let's substitute [tex]a = e-15[/tex] into [tex]a+e=45[/tex] as a.
[tex](e - 15) + e = 45[/tex]
We can now simplify this equation and solve for e.
[tex]2e-15 = 45\\2e = 60\\e = 30[/tex]
So we know that Elga is 30 years old. To find Alvin's age, we can substitute the value of e (30) back into one of the equations. Let's do it for [tex]a+e=45[/tex].
[tex]a + 30 = 45\\a = 45-30\\a=15[/tex]
So Elga is 30 years old and Alvin is 15 years old.
