Answer:
The alternate hypothesis is:
[tex]H_{a} < 16[/tex]
Step-by-step explanation:
There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.
This means that the null hypothesis is [tex]H_{0} = 16.4[/tex]
Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:
[tex]H_{a} < 16[/tex]
Which line shows the first error in the solution?
Answer:
The first error is in line 1.
Step-by-step explanation:
The equation that represents the statement is:
[tex]4-\frac{x}{3}=11[/tex]
it is four (4) less than a number (x) divided by three (3) is 11.
Therefore, we need to start from this equation, so the first error is in line 1.

Answer:
x2
Step-by-step explanation:
x2+12x+11=0
x2+(11+1)x+11=0
x2+11x+1x+11=0
x(x+11)+1(x+11)=0
(x+11)(x+1)=0
either,
x+11=0
x=-11
OR,
x+1=0
x=-1
{-11,-1}

Answer:
4+12= 16 so answer 3
Step-by-step explanation:
put four in place of x
Answer:
3. 16
Step-by-step explanation:
x=4
therefore x is worth four so we can replace x with the number 4
4+12
4+12=16

Answer:
Step-by-step explanation:
Upon factoring all terms we are left with the product of
[(x-4)(x+6)(x-6)]/[5(x-6)(3x+5)(x-4)]
The (x-4)s and (x-6)s cancel out and we are left with
(x+6)/(5(3x+5)) which is also equal to
(x+6)/(15x+25)

Question 13 please help& give explanation if possible thank u
Answer:
Step-by-step explanation:
Pilot Shop is a catalog business providing a wide variety of aviation products to pilots throughout the world. Maynard Shephard, the recently hired assistant controller, has been asked to develop a cost function to forecast shipping costs. The previous assistant controller had forecast shipping department costs each year by plotting cost data against direct labor-hours for the most recent 12 months and visually fitting a straight line through the points. The results were not satisfactory.
After discussions with the shipping department personnel, Maynard decided that shipping costs could be more closely related to the number of orders filled. He based his conclusion on the fact that 10 months ago the shipping department added some automated equipment. Furthermore, he believes that using linear regression analysis will improve the forecasts of shipping costs. Cost data for the shipping department have been accumulated for the last 25 weeks. He ran two regression analyses of the data, one using direct labor-hours, and one using the number of cartons shipped. The information from the two linear regressions follows:
Regression 1 Regression 2
Equation SC = 804.3 + 15.68DL SC = 642.9 + 3.92NR
R-squared .365 .729
Standard error of the estimate 2.652 1.884
t-value 1.89 3.46
where:
SC = total shipping department costs DL = total direct labor-hours
NR = number of cartons shipped
Required
1. Identify which cost function (regression 1 or regression 2) Pilot Shop should adopt for forecasting total shipping department costs and explain why.
2. If Pilot Shop projects that 600 orders will be filled the coming week, calculate the total shipping depart- ment costs using the regression you selected in requirement 1.
3. Explain two or three important limitations of the regression you selected in requirement 1, and identify one or two ways to address the limitations. Specifically include in your discussion the effect, if any, of the global nature of Pilot Shop’s business.
Step-by-step explanation:
1. The second regression should be adopted for forecasting because the R² is higher in this regression and the standard error is also smaller. the t value is also better in this regression compared to the first
2. Using regression 2, the estimated shipping cost is to be calculated here.
= 642.9 + 3.92NR
NR = 600
642.9 + 3.92X600
= 642.9 + 2352
= $2994.9
This is the estimated shipping cost.
3. The limitations could be due to error in data, the data could be unreliable because of the presence of outliers. Pilot shop is a global business so there is another factor to adds to the limitations, as this costs of buying and shipping are affected by fluctuations in exchange rate and variations in the global market.

187÷20=??
Plz help me and plz show your work.
Answer:
9.35
Step-by-step explanation:
This is a simple division problem all you have to do is 187 by 20 to get 9.35
Answer:
9.35
Step-by-step explanation:
In order to solve this, we need to use a method called long division. Long division is dividing but on a bigger scale. You would set up the problem like this:
187 ÷ 20
Now you see how many times 20 goes into 187.
Since it goes into 187 9 times, we know that our whole number is going to be 9. You would then need to figure out how many times 2 goes into 7. Because 2 goes into seven 3 1/2 times, we can now put our answer together. 9.35 is the answer.
You could also just use a calculator. Using a calculator would be much faster and simpliler.
I hope this helps. Please let me know if you need any more help. Have a great day!

Answer:
A'(-3, 13)
Step-by-step explanation:
The transformation that moves a point 4 left and 8 up is ...
(x, y) ⇒ (x -4, y +8)
The transformation that reflects a point across the y-axis is ...
(x, y) ⇒ (-x, y)
Applied after the translation, the transformation of ∆ABC becomes ...
(x, y) ⇒ (-(x -4), y +8) = (4 -x, y +8)
Then point A gets moved to ...
A(7, 5) ⇒ A'(4 -7, 5 +8) = A'(-3, 13)
___
In the attached graph, the purple triangle is the result of the translation 4 left and up 8. Then the blue one is after reflection across the y-axis.
1. The diameter of a circle is 8. what is the radius?
Answer:
Radius = 4
Step-by-step explanation:
r = d/2
r = 8/2
r = 4
Answer:
4
Step-by-step explanation:
The diameter of a circle is the length of a straight line from two opposite points on the circle. The radius is the length of a straight line from the middle to a point on the circle. This means that the diameter must be double the radius. So to find the radius, divide the diameter by 2. Since 8/2=4, the radius is 4.

Answer: Question 10 is c
Question 11 is c
Step-by-step explanation: Area of a circle is πr^2 so we know what the radius r is, it is 9.5 so we plug it in π(9.5)^2
Question 11 To get the radius from the diameter we need to know the half of the diameter which is 21=r
So we plug in 2πr is the equation for the circumference 2π(21) which then would be c

Which graph shows equivalent ratios?
A. On a coordinate plane, a line goes through points (2, 3) and (4, 4).
B. On a coordinate plane, a line goes through points (2, 2) and (3, 6).
C. On a coordinate plane, a line goes through points (1, 2) and (2, 4).
D. On a coordinate plane, a line goes through points (0, 6) and (1, 5).
Answer:
D
Step-by-step explanation:
It is because you can see the line pass through the value 0 in x-axis while 6 in y-axis which gives the first coordinate (x,y) = (0,6) and the line also past through the value of 5 in x-axis and 1 in y-axis which gives the second coordinate is (1,5).
So it is true that the line did go through at points (0,6) and (1,5).
