A company issues a general knowledge test to its potential employees as part of its recruitment procedures. The company does not invite the lowest scoring 20% back for a second interview. If the scores on this test are normally distributed with a mean of 60 and a standard deviation of 17. What mark (to the nearest whole number) must a candidate achieve in order to secure a second interview

Answers

Answer:

Step-by-step explanation:

Given :

Lowest scoring 20% ; this corresponds to score below (1 - 0.2) = 0.8

Mean, m = 60

Standard deviation, s = 17

Zscore = (x - mean) / standard deviation

Therefore, the Zscore for the bottom 20% equals ; P(x > Z) = 0.8

Using a Z probability calculator ;

The Zscore = -0.842

Therefore to Obtian the score, x

Zscore = (x - mean) / standard deviation

-0.842 = (x - 60) / 17

-0.842 * 17 = (x - 60)

-14.314 = x - 60

-14.314 + 60 = x

x = 45.686

To secure a second interview, candidate must score, 46 (nearest whole number).

The marks (to the nearest whole number) must a candidate achieve in order to secure a second interview is 46 and this can be determined by using the z-score formula.

Given :

A company issues a general knowledge test to its potential employees as part of its recruitment procedures.The company does not invite the lowest scoring 20% back for a second interview.If the scores on this test are normally distributed with a mean of 60 and a standard deviation of 17.

Let 'x' be the mark must a candidate achieve in order to secure a second interview.

So, through the z-score formula, the value of 'x' can be determined.

[tex]\rm z_{score} = \dfrac{x-mean}{Standard\; Deviation}[/tex]

[tex]\rm -0.842 = \dfrac{x-60}{17}[/tex]

[tex]17\times -0.842 = x - 60[/tex]

x = 60 - 14.314

x = 45.686

So, the marks (to the nearest whole number) must a candidate achieve in order to secure a second interview is 46.

Answer:

Step-by-step explanation:

1) Regular price = $ 20

Reduction = 18% of regular price

= 0.18 * 20

= 3.6

Discount price = 20 - 3.6 = $ 16.4

2) Regular price = $ x

Reduction = 18% of regular price

= 0.18 * x

= 0.18x

Discount price =$ (20 - 0.18x)

3) Discount price = $ 18.45

Let the regular price be x

(100 - 18)% of x = 18.45

82% of x = 18.45

[tex]\frac{82}{100}*x=18.45\\\\ x = 18.45* \frac{100}{82}\\\\ x = 22.50[/tex]

Regular price = $22.50

A school district is considering moving the start of the school day at Groveland High from 8:00 a.m. to 9:00 a.m. to allow students to get more sleep at night. They want to estimate how many more hours of sleep teens get if their school starts at 9:00 a.m. compared to teens whose schools start at 8:00 a.m. The district takes random samples of 50 of students from Groveland High and 39 students from Phillips High School, which starts at 9:00 a.m., and surveys them about their sleep habits. The sample mean number of hours of sleep per student at Groveland is 7.1 hours, and the standard deviation is 1.7 hours.

Mensualmente el número de árboles talados aumenta en un 9% respecto del mes anterior. Si este mes hay 85.000 árboles talados, ¿cuántos árboles talados habrá, aproximadamente, en 6 meses más?

Answers

Answer:

FV= 639.483 arboles

Step-by-step explanation:

Dada la siguiente información:

Cantidad de árboles talados (A)= 85.000

Proporción de crecimiento (g)= 9% mensual

Cantidad de meses (n)= 6

Para calcular el total de árboles talados en 6 meses, tenemos que usar la siguiente formula:

FV= {A*[(1+i)^n - 1]} / i

A= cantidad de árboles talados

i= proporcion de crecimiento

n= cantidad de meses

FV= {85.000*[(1.09^6) - 1]} / 0.09

FV= 639.483 arboles

Ahora, la cantidad de árboles que se talaran en el sexto mes:

FV= PV*(1+i)^n

FV= 85,000*(1.09^6)

FV= 142.553

c. 23 inches Yes : No
d. 5 inches Yes : No
e. 25 inches Yes : No
f. 10 inches Yes : No

Answers

Answer:

Step-by-step explanation:

The length of AC should be between 5 inches and 25 inches

Jose in this problem draws a triangle, ABC.

We know the length of two sides of the triangle:

AB = 10 inches

BC = 15 inches

The length of the third side in a generic triangle can be calculated using the cosine theorem:

where

a, b, c are the three sides

is the angle opposite to side

Looking at the formula, we observe that:

- The maximum value for is obtained for , so that . In this case, the length of the missing side (AC, in this case) is

- The minimum value for is obtained for , for which , so in this case the length of AC is

So, the length of AC must be between 5 and 25 inches.

Brianna can buy up to 5 books without spending more than her gift certificate amount.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

If each book costs $9 and Brianna has a $50 gift certificate, we can start by dividing the total amount she can spend by the cost of each book.

$50 gift certificate / $9 per book = 5.55 books

Since Brianna cannot buy a fractional part of a book, she can only purchase a whole number of books.

Therefore, the maximum number of books she can buy without spending more than her gift certificate amount is 5 books.

Additionally, there is a $5 shipping charge for the entire order, so Brianna should make sure to factor this into her budget.

If Brianna buys 5 books at $9 each, the total cost of the books will be $45. Adding the $5 shipping charge brings the total to $50, which is the exact amount of her gift certificate.

Therefore, Brianna can buy up to 5 books without spending more than her gift certificate amount.
