A. 1143
B. 88

Thank you to anyone who helps me I greatly appreciate beyond measures! :)
Answer:
Step-by-step explanation:
1/2(13-5)+(4+8)^2
A. 148
B. 144
C. 20
D. 16
We must follow "PEMDAS" order of operations rules. Anything inside parentheses must be done first, followed by exponentiation, multiplication and division, and finally additionl and subtraction.
1/2(13-5)+(4+8)^2 has three sets of parentheses enclosing mathematical expressions: (1/2), (13 - 5) and (4 + 8). These evaluate to:
1/2, 8, 12
and so we now have (1/2)(8) + (12)^2
Exponentiation is next. We get: (1/2)(8) + 144
Next is multiplication: 4 + 144
Last is addition: 148
Answer A is correct: 148
8 x 9+4^2-(63/7)
is evaluated in the same way:
8 x 9+4^2-(9), followed by exponentiation:
8*9 + 16 - 9, followed by multiplication:
72 + 16 - 9 = 79 (Answer C)

5. In a simple random sample of 120 women and 150 men from
a population of 150,000, 25% of the women and 37% of the men
are smokers. Suppose you are interested in comparing the
proportion of smokers by sex, do we accept or reject the null
hypothesis of assuming the smoking proportions of women and
men are the same with a .15?
Using the z-distribution, it is found that since the absolute value of the test statistic is greater than the critical value, the null hypothesis is rejected.
At the null hypothesis, we test if the proportions are the same, that is, their subtraction is 0, hence:
[tex]H_0: p_1 - p_2 = 0[/tex]
At the alternative hypothesis, it is tested if they are different, that is, their subtraction is not 0, hence:
[tex]H_1: p_1 - p_2 \neq 0[/tex]
The proportions and their respective standard errors are given by:
[tex]p_1 = 0.25, s_1 = \sqrt{\frac{0.25(0.75)}{120}} = 0.0395[/tex]
[tex]p_2 = 0.37, s_2 = \sqrt{\frac{0.37(0.63)}{150}} = 0.0394[/tex]
For the distribution of the difference, the mean and the standard error are given by:
[tex]\overline{p} = p_2 - p_1 = 0.37 - 0.25 = 0.12[/tex]
[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0395^2 + 0.0394^2} = 0.0558[/tex]
The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{s}[/tex]
In which [tex]p = 0[/tex] is the value tested at the null hypothesis.
Hence:
[tex]z = \frac{\overline{p} - p}{s}[/tex]
[tex]z = \frac{0.12 - 0}{0.0558}[/tex]
[tex]z = 2.15[/tex]
The critical value for a two-tailed test, as we are testing if two values are different, with a significance level of 0.15 is [tex]|z^{\ast}| = 1.4395[/tex].
Since the absolute value of the test statistic is greater than the critical value, the null hypothesis is rejected.

Halloween Candy Halloween is Kelly's favorite holiday of the year! Based on experience, Kelly knows that on average, each house gives him about 4 candies with a standard deviation of 1.5 candies. Each year Kelly visits 35 random houses in his neighborhood. Let X be the total number of candies Kelly will receive from his visits. Last Halloween, Kelly got 122 candies. Approximate the probability that the total number of candies Kelly will receive this year is smaller than last year.
Using the normal distribution and the central limit theorem, it is found that there is an approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.
Normal Probability Distribution
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, for n instances of a normal variable, the mean is [tex]n\mu[/tex] while the standard deviation is [tex]s = \sigma\sqrt{n}[/tex].In this problem:
Mean of 4 candies, hence [tex]\mu = 4[/tex].Standard deviation of 1.5 candies, hence [tex]\sigma = 1.5[/tex].She visited 35 houses, hence [tex]n = 35, \mu = 35(4) = 140, s = 1.5\sqrt{4} = 3[/tex]The probability is the p-value of Z when X = 122, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{122 - 140}{3}[/tex]
[tex]Z = -6[/tex]
[tex]Z = -6[/tex] has a p-value of 0.
Approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.

Write an equation for each translation of y = |x|.
16.5 units right
A. y = | x | + 16.5
B. y = | x | – 16.5
C. y = | x + 16.5 |
D. y = | x – 16.5 |
Answer:
D. y = | x – 16.5 |
Step-by-step explanation:
If you want to write an equation for an absolute value function this is the parent function y=a|x-h|+k.
In order to write an equation that is 16.5 units right you would do this:
y=|x-16.5|
If you are moving units left the number -16.5 would become 16.5
Remember when you are moving that the number inside is always the opposite sign of where you are moving
Here is the answer:
y=|x-16.5|
Hope This Helps!
...............................................................................................................................................
Just subtract 16.5 to the x , in parenthesis, to the existing equation.
For example,

The expressions equivalent to 3 (6e + 4) + 8 (e + 2) + 6e are : 4(8e + 7) And 28 + 32e
What are equivalent expressions?Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions. To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
Given the expression as;
3 (6e + 4) +8 (e + 2) + 6e.
Expand the brackets ;
18e + 12 + 8e + 16 + 6e
Now Collect like terms together and simplify;
=18e + 8e + 6e + 12 + 16
=32e + 28
=28 + 32e
Then factorizing the result, we have;
32e + 28 = 4(8e + 7)
The expressions equivalent to 3 (6e + 4) + 8 (e + 2) + 6e are : 4(8e + 7) And 28 + 32e

2 x 2 x 2 x 5
Step-by-step explanation:
The first few prime numbers: {2, 3, 5, 7, 11, 13, 17, 19}
One way to start is to divide by the first prime until you can't do that any more, then try the next prime and so on until all the numbers in your list are prime.
40 = 2(20) divide 20 by 2 again
40 = 2(2)(10) divide 10 by 2 again
40 = 2(2)(2)(5) stop--all factors are prime.
