A sample of 5 months of sales data provided the following information:

Month 1 2 3 4 5
Units Sold 97 120 88 97 93

Required:
a. Develop a point estimate of the population mean number of units sold per month (to 1 decimal).
b. Develop a point estimate of the population standard deviation (to 2 decimals).

Answers

Answer:

a. 99

b. 12.31

Step-by-step explanation:

a. Estimate of the population mean number of units sold per month

n = Number of Data Values = 5

Sum of Data Values = Σxi =97 + 120 + 88 + 97 + 93 = 495

Sample Mean = X = Σxi/n = 495 / 5 = 99

The population mean number of units sold per month is 99

b. Estimate of the population standard deviation

Month Data (x) X x - X (x - X)^2

1 97 99 -2 4

2 120 99 21 441

3 88 99 -11 121

4 97 99 -2 4

5 93 99 6 36

Sum of deviation squared 606

s^2 = Sample Variance = Σ(xi - X)2/(n - 1)

Sample Variance = 606/4 = 151.5

Sample Standard Deviation = √Sample Variance

Sample Standard Deviation = √151.5

Sample Standard Deviation = 12.30853362509117

Sample Standard Deviation = 12.31

The point estimate of the population standard deviation is 12.31

Triangle ABC in the figure above represents the area serviced by a shipping company that plans to build a distribution center at the incenter of the triangle located at point E. A circle is constructed to represent the location of the center. The diameter of the circle is 28 miles. The existing road is perpendicular to the incenter and the company is looking to build 2 more perpendicular roads but connecting the other 2 sides of the triangle. How many more miles of road will be needed?

Select one:
A. 28
B. 34
C. 43
D. 56

Answers

Answer:

A. 28

Step-by-step explanation:

A. 28

step 1.

We know that the diameter of the circle inscribed within the triangle is 28 miles, and we know that E is the incenter of triangle ABC.

step 2.

Next, we learned that the perpendicular legs from the incenter to the sides of the triangle are congruent, and we know that the radius of a circle is 1/2 of the diameter of the circle.

step 3.

Since the diameter of the circle is 28, we know the distance of segment DE is 14. Next, we know the perpendicular legs are equal to segment DE. Thus, we can solve for the amount of additional miles of road by writing 14 + 14 = 28.

What is the value of x in the equation *x - y = 30, when y = 15?
4.
ООО

80
200

Answers

Answer:

Step-by-step explanation:

[tex]x[/tex] - [tex]y[/tex] = 30 and [tex]y[/tex] = 15

So, I guess you are just messed up with the Xs and Ys.

And I'm not sure what is the 4. ООО 8 80 200 about but here is my guess :

So [tex]x[/tex] - [tex]y[/tex] = 30 and [tex]y[/tex] = 15.

First step, substitute the [tex]y[/tex] into the equation [tex]x[/tex] - .

So, it would be

[tex]x[/tex] - 15 = 30.

Now, we need the value of [tex]x[/tex].

[tex]x[/tex] - 15 = 30

Group the terms together :

[tex]x[/tex] - 15 ( +15 ) = 30 ( +15 )

So, [tex]x[/tex] would be equals to 30 + 15. And in other words, it would be 45.

So :

[tex]x[/tex] = 45.

Wanna check whether my answer's correct?

Substitute [tex]x[/tex] into [tex]x[/tex] - 15 = 30

That would be :

45 - 15 = 30

So is 45 - 15 = 30?

Yep.

So 45 is the answer.

The value of X is 45.

Team score in first game < 19

Step-by-step explanation:

Point Scored in Third Game =X

Points Scored in First Game = X+6 (6 more than third game)

Points Scored in Second Game = 23

Total Points ={( First Game) +( Second Game) + (Third Game)} < 55

{ ( X+6) + (23) + (X)} < 55

X+29+X < 55

2X+29 < 55

2X< 55-29

2X < 26

X <26/2

X<13

So the point scored in First game is: (X+6)

Where X < 13

So the point in First game is < 19

Days Percentage Illumination

1 2%

Notice that as the number of days increase by 1, the percentage illumination of the moon increase at different intervals

This means that the percentage illumination is not a linear function of day

Write an equation that represents the following word problem.
Jackie has four more apples than Mark and together they have twelve apples. How many apples do each Jackie and Mark have?
a + (a - 4) = 12
a + (a + 4) = 12
both of these would work
neither of these would work

Answers

Answer:

Both would work.

Step-by-step explanation:

If we call Jackie's apples a, then Mark has a - 4 apples. Therefore, together they have a + (a - 4) apples, and we know that they have a total of 12 apples so we can write a + (a - 4) = 12 to represent the situation. On the other hand, if Mark has a apples, then Jackie has a + 4 apples, so we can also write a + (a + 4) = 12 to represent the situation as well. Therefore, both of the equations would work. Hope this helps!

both
