Answer:
8,10,12
Step-by-step explanation:
Answer:
integer 1 = 8
integer 2 = x+2 = 8+2 = 10
integer 3 = x+4 = 8+4 = 12
Step-by-step explanation:
integer 1 = x , smallest
integer 2 = y , x+12
integer 3 = z , largest, x+4
three times the smallest is twice the largest.
3 (x) = 2 (x+4)
solve for x:
3x = 2x + 8
3x-2x = 8
x = 8
Replacing:
integer 1 = 8
integer 2 = x+2 = 8+2 = 10
integer 3 = x+4 = 8+4 = 12
Two years ago, the average number of customers in your all of your company's stores per week was 3173 customers. This figure had increased 6% over the previous two years. Assume that you are doing a current study to test the claim that the mean weekly number of customers is different than it was two years ago. Assume a population standard deviation of 1,550 customers. Suppose you look at a random sample of 73 stores and find an average weekly customer total of 3,391. You wish to test the claim stated above at the 0.10 level. Run the appropriate hypothesis test.
Required:
Write ONLY the conclusion to your hypothesis test.
Answers
Answer:
Accept the null hypothesis
Step-by-step explanation:
Two years ago, the average number of customers in your all of your company's stores per week was 3173 customers. Assume that you are doing a current study to test the claim that the mean weekly number of customers is different than it was two years ago.
The null hypothesis is:
[tex]H_{0} = 3173[/tex]
The alternate hypothesis is:
[tex]H_{A} \neq 3173[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Due to our test, we have that [tex]\mu = 3173[/tex]
Assume a population standard deviation of 1,550 customers.
This means that [tex]\sigma = 1550[/tex]
Suppose you look at a random sample of 73 stores and find an average weekly customer total of 3,391.
This means that [tex]n = 73, X = 3391[/tex]
Test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{3391 - 3173}{\frac{1550}{\sqrt{73}}}[/tex]
[tex]z = 1.24[/tex]
p-value:
Since we are testing if the mean is different of a value, and the z-score is positive, the pvalue is 2 multiplied by 1 subtracted by the pvalue of z = 1.24.
z = 1.24 has a pvalue of 0.9251
2*(1 - 0.9251) = 2*0.0749 = 0.1498
0.1498 > 0.1, which means that we accept the null hypothesis, that is, that the mean weekly number of customers is equal to what it was two years ago at the 0.1 level of significance.

Step-by-step explanation:

-4=24+b
(add 24 both sides)
20=b
slope: -12
y intercept: (0,20)
Answer:
y + 4 = -12(x - 2)
Step-by-step explanation:
Use the point-slope formula for the equation of a straight line:
y - k = m(x - h)
Here m = -12, h = 2 and k = -4, and so we have:
y + 4 = -12(x - 2)

Answers
9514 1404 393
Answer:
316 lumens/m²
Step-by-step explanation:
We assume your intensity function is ...
f(x) = 50,000(0.975^x) . . . . x meters below the surface
__
Use 200 for x and do the arithmetic.
f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²

Kiki's mother cooked a dinner that contained a total of 992 calories. She also prepared a dessert that contained a total of 846 calories. The dinner was divided into 4 equal servings. The dessert was divided into 6 equal
servings. Kiki had one serving of dinner and one serving of dessert.
Which equation could be used to solve for n, the number of calories that kiki
ate?
A. n = 992 x 4 + 846 x 6
B. n = 1,838 / 10
C. n = 992 / 4 + 846 / 6
D. n = 992 / 4 - 846 / 6
Answers
Answer: C
Step-by-step explanation:
992/4=165
846/6=141
