Answer:

The 98% of the confidence interval for the true average salary of Knirhsdaeh employees as a psychology counselor

(75.4206, 86.5794)

Step-by-step explanation:

Step(i):-

Given that the mean of the sample = $81 k

Given that the size of the sample 'n' = 23

Given that the standard deviation for the salaries is $13 k

Step(ii):-

98% of the confidence interval for the true average salary of Knirhsdaeh employees is determined by

[tex](x^{-} - t_{0.02} \frac{S.D}{\sqrt{n} } , x^{-} + t_{0.02} \frac{S.D}{\sqrt{n} })[/tex]

Degrees of freedom = n-1 = 23-1 =22

[tex]t_{0.02} = 2.5083[/tex]

[tex](81 - 2.0583 \frac{13}{\sqrt{23} } , 81 + 2.0583 \frac{13}{\sqrt{23} } )[/tex]

( 81 - 5.57940 , 81 + 5.57940)

(75.4206, 86.5794)

Final answer:-

The 98% of the confidence interval for the true average salary of Knirhsdaeh employees as a psychology counselor

Answer:

the correct answer is 2 no real solurions hope this helps

Answer:

18

Step-by-step explanation:

11 - 1/3x = 5

Subtract 11 from both sides

-1/3x = -6

Multiply both sides by -3

x = 18

Answer:

Step-by-step explanation:

-3 + 1/2n = 1/2 (-n + 14)

distribute

-3 + 1/2n = -1/2n + 7

                 -1/2n

cancel out -1/2n

-3 = n + 7

-10 = n

subtract 7

n =  -10

Answer:

  18°

Step-by-step explanation:

Angle ACD is the complement of the 18° angle shown, 72°. Arc AB is double that measure, so is 144°. Arc BE is the supplement to that, so is 36°. This is the arc subtended by inscribed angle BAE. That inscribed angle is half the measure of arc BE, so is 36°/2 = 18°.

  angle BAE = 18°

Answer:

Step-by-step explanation:

Given ,

Radius of the cylinder = 5 cm

Height of the cylinder = 5 cm

Therefore,

Total surface area of the cylinder

[tex] = 2\pi r(r + h)[/tex]

[tex] = 2\pi \times 5(5 + 5) {cm}^{2} [/tex]

[tex] = 10\pi \times 10 {cm}^{2} [/tex]

[tex] = 100\pi {cm}^{2} [/tex]

Hence,

The required value to put in the green box is 100(Ans)

Answer:

Answer:

Part A: c. 4.25x+7=53.75

Part B: 11

Step-by-step explanation:

4.25x+7=53.75

4.25x=46.75

x=11

Step-by-step explanation:

Lets take Vald spends $100 on the book fair which are all the money he had.

Pamela Spends 2/3 as much as Vald

Pamela Spends 2/3 x 100 = $66.67

Eli Spends 4/3 as much as Vald

Eli spends 4/3 x 100 = $133.33

From here, we can see Eli Spends the most and Pamela Spends the least.

can I have the brainliest please?

Answer:

B

Step-by-step explanation:

B is correct.  According to the distributive property of multiplication, we have 3(30 - p)  =  3·30 - 3·p

I did the diagnostic

Answer: graph 1 —> u-v

graph 2—> u-w

graph 3—> w-v

graph 4—> v-u

*Look at both pictures to make sure this is for your specific question

Step-by-step explanation: I got this right on Edmentum

Graph 1 represents the vector u - v, graph 2 represents the vector u - w, graph 3 represents the vector w - v, and graph 4 represents the vector v - u.

It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have vectors u, v, and w given in the picture:

u = <-2, -7>

v = <3, -4>

w = <5, 1>

= u - v

=  <-2, -7> - <3, -4>

= <-5, -3>

= u - w

=  <-2, -7> - <5, 1>

= <-7, -8>

= w - v

=  <5, 1>  - <3, -4>

= <2, 5>

= v - u

= <3, -4> - <-2, -7>

= <5, 3>

Thus, graph 1 represents the vector u - v, graph 2 represents the vector u - w, graph 3 represents the vector w - v, and graph 4 represents the vector v - u.

Answer:

4

Step-by-step explanation:

If you add up all of those, you get 24. Then you divide by 6. 24/6 = 4.

Answer:

Proved

Step-by-step explanation:

From the given parameters, we have:

[tex]n = 9[/tex] i.e. the length of each security numbers

[tex]r = 2[/tex] i.e. 2 security numbers

Required

In 513 security numbers, 2 must have matching zeros

To do this, we make use of Pigeonhole principle.

First, we calculate the number of all security numbers not having matching zeros.

Each of the 9 digits can be selected in 2 ways.

2 ways implies that each digit is either 0 or not

So, total selection is:

[tex]Total = 2^9[/tex]

[tex]Total = 512[/tex]

Apply Pigeonhole principle

The principle states that: suppose there are n items in m containers, where [tex]n>m[/tex], then there is at least one container that contains more than 1 item.

This means that if there are 512 security number without matching zeros, then there is 1 (i.e. 512 + 1) with matching zeros.

[tex]512 + 1 = 513[/tex]
