An experiment involves selecting a random sample of 256 middle managers for study. One item of interest is their annual incomes. The sample mean is computed to be $35,420.00. If the population standard deviation is $2,450.00, what is the standard error of the mean
Answer:
the standard error is 153.125
Step-by-step explanation:
given that
The random sample is 256
The sample mean is $35,420
And, the standard deviation is $2,450
We need to find out the standard error
We know that
= standard deviation ÷ √random sample
= 2450 ÷ √256
= 2450 ÷ 16
= 153.125
Hence, the standard error is 153.125

A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful only if the average time spent on a delivery does not exceed 40 minutes. The owner has randomly selected 21 customers and delivered pizzas to their homes. What hypotheses should the owner test to demonstrate that the pizza delivery will not be successful
Answer:
H0 : u ≤ 40 mins against Ha: u> 40 mins
Step-by-step explanation:
The hypotheses will be set as follows
H0 : u ≤ 40 mins against Ha: u> 40 mins
The null hypothesis is that the mean delivery time is less and equal to 40 minutes.
against the claim
that the mean delivery time is greater than 40 minutes.
40 minutes is taken because the success depends on the factor that if the delivery time is less and equal to 40 minutes then the home delivery service will be successful
But if it is greater than 40 minutes then the home delivery service will not be successful

Under the translation (x,y) → (x + 1, y + 3), the point (1,8) will become what point?
Answer:
[tex](1,8) \to (2,11)[/tex]
Step-by-step explanation:
Given
[tex](x,y) \to (x + 1,y+3)[/tex]
Required
Translation of [tex](1,8)[/tex]
We have:
[tex](x,y) \to (x + 1,y+3)[/tex]
This gives:

A student scored 82, 95, 90 and 87 on his first 4 tests. What would he
need to make on his 5th test to have an average 95.
Not gonna give an answer, sorry. Instead, I'll show you a similar example so you can be able to solve it.
An average test score is the sum of all the scores on an assessment divided by the number of test-takers.
For example, if three students took a test and received scores of 69, 87, and 92.
These numbers would be added together and then divided by three to get an average of 82.6.
I hope you know what to do now.
Answer:
Step-by-step explanation:
(82 + 95 + 90 + 87 + x) / 5 = 95 Add like terms on the left
(354 + x) / 5 = 95 Multiply by 5
354 + x = 95 * 5
354 + x = 475 Subtract 354 from both sides
x = 475 - 354
x = 121
On the first step, you need to add an x which represents the score he needs. You divide by 5 because that's how many scores there and and the 5 gives you an average.
Find the range for the measures for the third side of a triangle with the given measures of two sides. 14 and 23
Given:
Two sides of a triangle are 14 and 23.
To find:
The angle for the measures for the third side of a triangle.
Solution:
If a, b, c are three sides of a triangle, then
[tex]a+b>c[/tex]
[tex]a+c>b[/tex]
[tex]b+c>a[/tex]
It is given that two sides of a triangle are 14 and 23.
Let the third side of the given triangle be c. Then, using the above inequalities, we get
[tex]a+b>c[/tex]
[tex]14+23>c[/tex]
[tex]37>c[/tex] ...(i)
Similarly,
[tex]a+c>b[/tex]
[tex]14+c>23[/tex]
[tex]c>23-14[/tex]
[tex]c>9[/tex] ...(ii)
And,
[tex]b+c>a[/tex]
[tex]23+c>14[/tex]
[tex]c>14-23[/tex]
[tex]c>-9[/tex] ...(iii)
Using (i), (ii) and (iii), we get
[tex]9<c<37[/tex]
Therefore, the range for third side of the triangle is [tex]9<c<37[/tex].

The value of sin C will be
sin C = 3 / 5
The value of sin D will be
sin D = 4 / 5
The value of cos C will be
cos C = 4 / 5
The value of cos D will be
cos D = 3 / 5
The value of tan C will be
tan C = 3 / 4
The value of tan D will be
tan D = 4 / 3
The product of sin D and cos D will be
sin D × cos D = (4 / 5) × (3 / 5)
sin D × cos D = 12 / 25
The product of tan C and tan D will be
tan C × tan D = (3 / 4) × (4 / 3)
tan C × tan D = 1
The product of cos C and tan D will be
cos C × tan D = (4 / 5) × (4 / 3)
cos C × tan D = 16 / 15
Then the matching will be given below.

What is the area of a rectangle with a length of (x - 5) and width of (x + 8)?
Answer:
a = x² + 3x - 40
Step-by-step explanation:
a = l * w
a = (x - 5)(x + 8)
a = x(x + 8) - 5(x + 8)
a = (x² + 8x) + (- 5x - 40)
a = x² + 3x - 40

B. What was the highest temperature this month?
Step-by-step explanation:
Rory is recording the highest temperature for the duration of the day for month's worth of data.
B. is the easiest one to answer, as you simply will have to look for the greatest number within the set, and that will be the answer.
A. is too broad, and does not imply that only the "high temperature" is needed, rather just a leveled temperature within day in that month.
C. is the opposite of what Rory had recorded, and without data, he cannot answer it.
D. is answerable as well, but, again, the only temperature recorded is the high temperature. Temperature can fluctuate depending on the time of the day, and can be in the 50s one hour and the 90s in another.

The table of values represent a linear function. Write an equation in slope-intercept form that represents the function.
Let's take the first value of x and y.
When x = 4, y = -3. This also gives us point
(4, -3). We need another point to find the slope.
From the table I see the point (5, -4.5)
.
See it?
Let m = slope
m = (-4.5 -(-3))/(5-4)
m = (-4.5 + 3)/1
m = (-1.5)/1
m = -1.5
Now, use the slope m and one of the points to plug into the point-slope formula.
Here is the point-slope formula:
y - y_1 = m(x - x_1)
I will use the point (4, -3) and m.
y - (-3) = -1.5(x - 4)
y + 3 = -1.5x + 6
The slope-intercept form we want is
y = mx + b.
y = -1.5x + 3
