2x(x - 3) + 7(x - 3)
Can I have an explanation on how it works factors
Answers
Answer:
Step-by-step explanation:
2x(x - 3) + 7(x - 3)
2x^2 - 6x + 7x - 21
reduce
2x^2 + x - 21
if this is equal to 0 then:
2x^2 + x - 21 = 0
factored:
(2x + 7)(x - 3) = 0
How that was done:
Divide the (2x^2) into (2x) and (x).
Divide the (-21) into (+7) and (-3). You choose these numbers so that their sum, when multiplied by (2x) and (-3), adds up to (+x).

(10-3)x(3-2^5) Use pemdas.
Answers
Answer:
-203
Step-by-step explanation:
(10−3)×(3−2^5 )
Subtract 3 from 10 to get 7.
7(3−2^5 )
Calculate 2 to the power of 5 and get 32.
7(3−32)
Subtract 32 from 3 to get −29.
7(−29)
Multiply 7 and −29 to get −203.
−203
So first we start with the parenthesis
(10-3) which is 7 and
(3-2^5) since exponents is next it would be (3-32) which is -29
So now we have 7 x -29 which is -203

Debra is buying prizes for a game at her school's fundraiser. The game has three levels of prizes, and she has already bought the second and third prizes. She wants the first prize to be nice enough to attract people to the game. The game's manufacturer has supplied her with the probabilities of winning first, second, and third prizes. Tickets cost $3 each, and she wants the school to profit an average of $1 per ticket. How much should she spend on each first prize
Answers
Answer:
$9.19
Step-by-step explanation:
We are given that
Cost of each ticket=$3
Average profit per ticket=$1
Expect gain for ticket purchaser must be -$1
Let x be the cost of first prize
Probability of first prize=0.15
Probability of second prize=0.30
Probability of third prize=0.45
Cost of second prize=$1.15
Cost of third prize=$0.74
Total probability=0.15+0.30+0.45=0.9
Probability of winning =0.9
Probability of losing=1-0.9=0.1
According to question
[tex]x(0.15)+0.30(1.15)+0.74(0.45)-3(0.1)=-1[/tex]
[tex]0.15x+0.378=-1[/tex]
[tex]0.15x=-1-0.378[/tex]
[tex]0.15x=-1.378[/tex]
[tex]x=-\frac{1.378}{0.15}=-9.19[/tex]
Hence, she spend money on each first prize=$9.19

The sum of two numbers is 55. The large number is 13 more than the smaller number. What are the numbers?
Answers
Answer:
x = 34
y = 21
thus the two numbers are 34 and 21...
The smaller number is 21, and the larger number is 34 when the sum of two numbers is 55. The large number is 13 more than the smaller number.
Let's assume the smaller number is represented by x.
According to the given information, the larger number is 13 more than the smaller number. So, the larger number can be represented as (x + 13).
The sum of the two numbers is 55. We can set up the equation:
x + (x + 13) = 55
Simplifying the equation:
2x + 13 = 55
Subtracting 13 from both sides:
2x = 42
Dividing both sides by 2:
x = 21
Now that we have found the value of x (the smaller number), we can find the larger number by substituting it back into the expression (x + 13):
Larger number = x + 13 = 21 + 13 = 34
Therefore, the smaller number is 21, and the larger number is 34.

Given the function f(x) = [tex]\frac{|x|}{x}[/tex] , find [tex]\lim_{x \to \00^-} f(x) and \lim_{x \to \00^+} f(x) and \lim_{x \to \00} f(x)[/tex]

Step 1: Define

Step 2: Graph/Evaluate
Graph the function so we can evaluate the given limits. See attachment.
We see from the function that when we approach 0 from the left, we will get a -1.
∴ [tex]\displaystyle \lim_{x \to 0^-} f(x) = -1[/tex]
We see from the function that when we approach 0 from the right, we will get a 1.
∴ [tex]\displaystyle \lim_{x \to 0^+} f(x) = 1[/tex]
Since the limit from the left does not equal the limit from the right, the limit as x approaches 0 of f(x) does not exist (DNE).

Suppose you have purchased a filling machine for candy bags that is supposed to fill each bag with 16 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 10 bags yields the following data (in oz):
15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10
On the basis of this data, can you conclude that the mean fill weight is actually less than 16 oz?

Step-by-step explanation:
Given the data:
15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10
Null hypothesis ; H0: μ ≥ 16
Alternative hypothesis ; H1: < 16
Sample size, n = 10
From the data:
Using calculator,
Sample mean, m = 15.887
Standard deviation, s = 0.13
The test statistic, T
(m - μ) / s/sqrt(n)
(15.887 - 16) / (0.13/sqrt(10))
= −2.748749
Using the p value from test statistic calculator :
Degree of freedom (df) = 10 - 1 = 9 at 0.05 significance level is 0.011275
Since the p value is < 0.05
0.011 < 0.05
We reject the Null and conclude that the mean fill weight is less than 16 oz

A restaurant serves hot chocolate that has a mean temperature of 175 degrees with a standard deviation of 8.1 degrees. Find the probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees. Would this outcome warrant a replacement cup (meaning that it would be unusual)
Answers
Answer: The probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees =0.042
This outcome would warrant a replacement cup.
Step-by-step explanation:
Let x be a random variable that represents the temperature of hot chocolates.
GIven: Mean temperature = 175 degrees
standard deviation = 8.1 degrees
The probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees =[tex]P(x<161)[/tex]
[tex]=P(\dfrac{x-\mu}{\sigma}<\dfrac{161-175}{8.1})\\\\=P(Z<-1.7284) [Z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(Z<1.7284)\\\\=1-0.9580\\\\=0.042[/tex]
Hence, the probability that a randomly selected cup of hot chocolate would have a temperature of less than 161 degrees =0.042 < 0.5 (unusual)
i.e. this outcome would warrant a replacement cup.
