Answer:
Width 2in
height 3in
length 4in
Step-by-step explanation:
If he want the length to be four he has to take 2 sqares off at the end to be left with his height as 3 so vertical from top to bottom and width (the two sqaures at the end of the photo to the left) would be 2. :)
Width of box=2in
Height of box=3in
Length of box=6in
Volume=2(3)(6)=36in³Now
length of the box is 4in
Product of width and height=36/4=9in²

-4 = r divided by 20 − 5
Solve for R
Answers
Answer:
20
Step-by-step explanation:
Simplify both sides of the equation.
−4= r 20 −5 −4= 1 /20 r+−5 −4= 1 /20 r−5
Flip the equation.
1 /20 r−5=−4
Add 5 to both sides.
1 /20 r−5+5=−4+5
1 /20 r=1
Multiply both sides by 20.
20*( 1 /20 r)=(20)*(1)
r=20

What are the two possible answers for the equation Ix/5I = 3?
Answers
Answer:
Either [tex]x = -15[/tex] or [tex]x = 15[/tex].
Step-by-step explanation:
[tex]|x| = \left\lbrace \begin{aligned} & x && \text{if $x \ge 0$} \\ & -x && \text{if $x < 0$}\end{aligned}\right.[/tex].
Hence, there are two possibilities to consider:
Either [tex](x / 5) \ge 0[/tex],Or [tex](x / 5) < 0[/tex].If [tex](x / 5) \ge 0[/tex], then [tex]|x / 5| = x / 5[/tex].
Substitute into the original equation: [tex]x/ 5= 3[/tex]. Solve for [tex]x[/tex]: [tex]x = 15[/tex].
Important: verify that the solution [tex]x = 15[/tex] meet the assumption [tex](x / 5) \ge 0[/tex]. Indeed, [tex](x / 5) = (15 / 5) = 3[/tex] and is indeed non-negative. Hence, the solution [tex]x = 15\![/tex] is valid.
On the other hand, if [tex](x / 5) < 0[/tex], then [tex]|x / 5| = - x / 5[/tex].
Substitute into the original equation: [tex](-x / 5) = 3[/tex]. Solve for [tex]x[/tex]: [tex]x = -15[/tex].
Similarly, verify that the solution [tex]x= - 15[/tex] satisfies the current assumption that [tex](x / 5) < 0[/tex]. Indeed, this assumption is met, and [tex]x = -15[/tex] is also a valid solution.

-5.2k+2.9 =-12k+30.1
Please show work !
Answers
answer: 3.8857
explanation:
Simplifying
-5k + 2.9 = -12k + 30.1
Reorder the terms:
2.9 + -5k = -12k + 30.1
Reorder the terms:
2.9 + -5k = 30.1 + -12k
Solving
2.9 + -5k = 30.1 + -12k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '12k' to each side of the equation.
2.9 + -5k + 12k = 30.1 + -12k + 12k
Combine like terms: -5k + 12k = 7k
2.9 + 7k = 30.1 + -12k + 12k
Combine like terms: -12k + 12k = 0
2.9 + 7k = 30.1 + 0
2.9 + 7k = 30.1
Add '-2.9' to each side of the equation.
2.9 + -2.9 + 7k = 30.1 + -2.9
Combine like terms: 2.9 + -2.9 = 0.0
0.0 + 7k = 30.1 + -2.9
7k = 30.1 + -2.9
Combine like terms: 30.1 + -2.9 = 27.2
7k = 27.2
Divide each side by '7'.
k = 3.885714286
Simplifying
k = 3.885714286

A furniture store routinely calls some customers to inquire about their buying experience in the showroom, the delivery and setup, and their overall satisfaction with
purchase. Today the calls will go to 2 homes randomly selected from last week's 5 customers. How many different groups of customers could the store call?
Answers
Answer:
10 different groups of customers could the store call
Step-by-step explanation:
Given the data in the question;
calling two (2) homes out of last week's five (5) customers;
so, there are 5 customers from last week and todays call needs to go to 2 customers randomly;
hence, Total group will be;
[tex]\left[\begin{array}{ccc}5\\2\\\end{array}\right][/tex] = 5! / ( 2! × ( 5 - 2 )!
= 5! / (2! × 3! )
= 10
Therefore, 10 different groups of customers could the store call
A graduate student is performing a study on a new antidepressant. The drug is supposed to reduce depression, but the graduate student realizes that it may do nothing or even increase depression, so she decides to formulate nondirectional hypotheses and conduct a two-tailed test. First, she uses mu_general population to denote the average score on the depression inventory for the population of all depressed people, and mu_antidepressant to denote the average score on the depression inventory for the population of depressed people who take the new antidepressant. She knows that the average score for all depressed people is mu_general population = 25, with a standard deviation of sigma = 6. The graduate student identifies the null and alternative hypotheses as: H_0: mu_antidepressant = mu_general population H_1: mu_antidepressant notequalto mu_general population The sample of 36 depressed people who tried out the new antidepressant scored an average of 23.3. Since the graduate student knows the standard deviation of the scores on the depression inventory for the population of people who are depressed, she intends to use a hypothesis test that uses the z-score of the sample mean as the test statistic (also known as the z test). First, she wants to make sure all the required assumptions are satisfied. Which of the following conditions is not a required assumption for the z test?
The scores on the depression inventory follow a normal distribution or the sample size is large (at least 30).
The standard deviation of the scores on the depression inventory is the same for those who take the antidepressant and those who don't.
Each observation is independent of every other observation.
The sample size must be very large.
Members of the sample are selected randomly.
Use the Distributions tool to find the critical region for alpha = .05. The critical z-scores (the values for z-scores that separate the tails from the main body of the distribution, forming the critical regions) are_______
Calculate the z statistic, and use the Distributions tool to evaluate the null hypothesis. The z statistic is______ The z statistic_______ lie in the critical region for a two-tailed hypothesis test. Therefore, the null hypothesis is______ .
Answers
Answer:
Step-by-step explanation:
From the given information:
The null and the alternative hypothesis is:
[tex]H_o: \mu_{antidepressant}= \mu_o[/tex]
[tex]H_1: \mu_{antidepressant}\ne \mu_o[/tex]
The population mean = 25
The sample mean = 23.3
sample size n = 36
standard deviation = 6
From the following conditions given; the condition that is not required is:
[tex]\text{The sample size must be very large}[/tex]
Since the sample size is 30, we do not need the condition and it's enough for the Z test provided that the population is not normally distributed. If the population is distributed normally, then any sample size is valid:
Then, the test statistics can be computed as follows:
[tex]Z = \dfrac{X - \mu}{\dfrac{\sigma}{\sqrt{n}} }[/tex]
[tex]Z = \dfrac{23.3 - 25}{\dfrac{6}{\sqrt{36}} }[/tex]
[tex]Z = \dfrac{23.3 - 25}{\dfrac{6}{6} }[/tex]
[tex]Z = -1.7[/tex]
At the level of significance 0.05
Since the test is two-tailed, the critical value [tex]Z_{\alpha/2} = Z_{0.025} = 1.96[/tex]
Provided that the Z value is not less than the critical value;
Then, we fail to reject the null hypothesis.
We conclude that there is no enough evidence that the drug reduces depression.
Everyone thought that Martha Mathy was trying to start a new fashion trend when she started wearing socks that did not match. her "look" started to catch on, and pretty soon all the kids at her school were wearing mixed-up socks, too. Rita Writer, a reporter for the school paper, interviewed Martha about the new sock trend. " Wat gave you the idea to wear mismatched socks?" Rita Asked.
"Its simple mathematics," Martha replied. "you see, I have 18 socks at home but no two are the same. with just these 18 socks, I can create over 100 unique pairs of mismatched socks." Rita found this hard to believe, so she checked it out. Was Martha correct?
Answers
Answer:
There are 153 combinations
Combinations - any two from eighteen is given by the formula 18C2 or 18! / (2!*16!)
= 18 * 17 / 2 = 153
OK that is the maths - now the explanation
The first sock can be any of 18
The second sock can be any of 17 (one already been selected and they must be mismatched)
Therefore there are 18*17 = 306 permutations she could make
However the question asks for "combinations" not "permutations"
A green sock on the right foot and a yellow sock on the left foot is deemed to be a different "permutation" to a yellow sock on the right foot and a green sock on the left foot. HOWEVER, they are regarded as the same "combination" in both cases you have one green and one yellow sock.
Therefore for combinations we must divide the 306 permutations calculated above by 2 = 153
FYI Walton has incorrectly given you the value of 18!. That would only apply if Martha Mathy had 18 feet!
