According to one source, the average cumulated college student loan debt for a graduating senior is $29,400. Assume that such debt is normally distributed and that the standard deviation is $5,684. Thirty percent of these graduating seniors owe more than what amount?

Answers

Answer:

$32378.416

Step-by-step explanation:

We are asked to find: Thirty percent of these graduating seniors owe more than what amount.

More than 30% = Finding the z score of the 70% percentile.

The z score = 0.524

Hence, using z score formula:

z = (x-μ)/σ

0.524 = x - $29,400/$5,684

0.524 × 5684 = x - 29400

2978.416 = x - 29400

x = 29400 + 2978.416

x = $32378.416

Therefore, Thirty percent of these graduating seniors owe more than what amount $32378.416.

A number is divisible by 18 if it is an even number AND the sum of its digits is divisible by 9. For example, 492,480 is divisible by 18 because it is an even number and the sum of its digits is 4 + 9 + 2 + 4 + 8 + 0 = 27 is divisible by 9.

How do you do this question?

Answers

Answer:

(-11 + √165) / 22

Step-by-step explanation:

∑₂°° (1 + c)⁻ⁿ

= ∑₂°° (1 / (1 + c))ⁿ

= ∑₁°° (1 / (1 + c))ⁿ⁺¹

This is a geometric series with a₁ = 1/(1+c)² and r = 1/(1+c).

The sum of an infinite geometric series is:

S = a₁ / (1 − r)

Therefore:

11 = 1/(1+c)² / (1 − 1/(1+c))

11 = 1 / ((1+c)² − (1+c))

11 ((1+c)² − (1+c)) = 1

11 (1 + 2c + c² − 1 − c) = 1

11 (c + c²) = 1

11c² + 11c − 1 = 0

c = [ -11 ± √(11² − 4(11)(-1)) ] / 22

c = (-11 ± √165) / 22

c cannot be between -2 and 0, so c = (-11 + √165) / 22.

The entrepreneurship club is ordering potted plants for
all 36 of its sponsors. One store charges $8.50 for each
plant plus a delivery fee of $20.
The equation 320 = x + 7.50(36) represents the cost
of ordering potted plants at a second store.
What does the x represent in this situation?
The cost for each potted plant at the second store
The delivery fee at the second store
The total cost of ordering potted plants at the second store
The number of sponsors of the entrepreneurship club
Yes

Answers

Answer:

The delivery fee at the second store

Step-by-step explanation:

The x represents the delivery charge.

The cost for each potted plant at the second store is $7.50.

The delivery fee at the second store is $50.

The total cost of ordering potted plants at the second store is $270.

The number of sponsors of the entrepreneurship club is 36.

Given,

The entrepreneurship club is ordering potted plants for all 36 of its sponsors.

One store charges $8.50 for each plant plus a delivery fee of $20.

The equation 320 = x + 7.50(36) represents the cost of ordering potted

plants at a second store.

We need to find:

-  what does the x represents

- the cost for each potted plant at the second store

- the delivery fee at the second store

- the total cost of ordering potted plants at the second store

- the number of sponsors of the entrepreneurship club

How do we represent a total cost with different charges and a number of items?

If the number of items = M

Cost of each item = $N

Charges = P

Then the total cost can be represented by:

= M x $N + P

The charges are separated since it's an individual charges.

The exclusive total cost for the items is:

= Number of items x Cost of each item.

We have,

Number of sponsors = 36

One store:

Cost of each plant = $8.50

Delivery fee = $20

Second store:

320 = x + 7.50(36)

This equation represents the cost of ordering plotted plants from the second store.

Here,

x = delivery charges

Cost of each plotted plant =  $7.50

The delivery fee at the second store:

320 = x + 7.50(36)

320 = x + 270

x = 320 - 270

x = $50

The total cost of ordering potted plants at the second store:

= 7.50 x 36

= $270

The number of sponsors of the entrepreneurship club:

= 36

Thus,

The x represents the delivery charge.

The cost for each potted plant at the second store is $7.50.

The delivery fee at the second store is $50.

The total cost of ordering potted plants at the second store is $270.

The number of sponsors of the entrepreneurship club is 36.

The probability that exactly three of four randomly selected students that do not prefer water is; P=125/1296= 0.096

Step-by-step explanation:

Hope this helps

The required probability that exactly 3 of 4 randomly selected students do not prefer water is 0.096.

Given that,
Students at Freeman Middle School have a choice of water milk or juice for breakfast.
From a survey, it was determined that 50 students prefer water 100 prefer juice, and 150 prefer milk.


What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

the probability that selected students to prefer water.
Total sample space = 300
Total desired events = 50
Pw = 50 / 300 = 1/6

the probability that selected students do not prefer water
Total sample space  = 300
Total desired events = 100+150 = 250

Pmj = (250)/300
     = 5/6


The probability for exactly 3 of 4 randomly selected students do not prefer water can be given as,

Preq =  Pmj.Pmj.Pmj.Pw

Preq = (5/6)^3 × 1/6

Preq= 125/1296
  = 0.096

Thus, the required probability that exactly 3 of 4 randomly selected students do not prefer water is 0.096.

Answers

Answer:

(a) 0.000061

(b) 0.000061

(c) 0.209

Step-by-step explanation:

An array of 14 bits is equally likely to be 0 or 1.

That is, P (0) = P (1) = 0.50.

(a)

Compute the probability that all bits are 1s as follows:

[tex]P(\text{All bits are 1s})=[P(1)]^{14}[/tex] ∵ the bits are independent

                            [tex]=(0.50)^{14}\\=0.00006103515625\\\approx 0.000061[/tex]

Thus, the probability that all bits are 1s is 0.000061.

(b)

Compute the probability that all bits are 0s as follows:

[tex]P(\text{All bits are 0s})=[P(0)]^{14}[/tex] ∵ the bits are independent

                            [tex]=(0.50)^{14}\\=0.00006103515625\\\approx 0.000061[/tex]

Thus, the probability that all bits are 0s is 0.000061.

(c)

Compute the probability that exactly 7 bits are 1s and 7 bits are 0s as follows:

Define X as the number of bits that 1s.

Then the random variable X will follows a binomial distribution with parameters n = 14 and p = 0.50.

The value of P (X = 7) is:

[tex]P(X=7)={14\choose 7}(0.50)^{7}(1-0.50)^{14-7}[/tex]

               [tex]=\frac{14!}{7!\times 7!}\times (0.50)^{14}\\\\=3432\times 0.000061\\\\=0.209352\\\\\approx 0.209[/tex]

Thus, the probability that exactly 7 bits are 1s and 7 bits are 0s is 0.209.

A ketchup company regularly receives large shipments of tomatoes. For quality control purposes, they take a sample of tomatoes from each shipment. If the sample shows convincing evidence that more than 8\%8%8, percent of the tomatoes in the entire shipment are bruised, then the company will request a new shipment of tomatoes. So the company tests H0 : p = 0.08 versus Ha ​: p > 0.08H, where p is the proportion of tomatoes in the entire shipment that are bruised.
One day, a supervisor takes a random sample of 600 tomatoes from a shipment and finds that 53 of the tomatoes are bruised, which results in a test statistic of z ≈ 0.75. Assuming that the necessary conditions are met, what is the approximate P-value associated with the significance test for this shipment?

Answers

Answer:

The value is   [tex]p-value  =  0.22663[/tex]

Step-by-step explanation:

From the question we are told that

    The proportion of bruised tomatoes p =  0.08

    The  null hypothesis is  [tex]H_o  :   p =  0.08[/tex]

    The alternative hypothesis is  [tex]H_a  :  p >  0.08[/tex]

    The sample size is  n  =  600

    The number of bruised tomatoes from the sample selected is  k  =  53

    The test statistics is  z =0.75

Generally the p-value is mathematically represented as

      [tex]p-value  =  P(Z > z)[/tex]

=>    [tex]p-value  =  P(Z > 0.75)[/tex]

From the z-table  

    [tex]P(Z > 0.75) =  0.22663[/tex]

So  

    [tex]p-value  =  0.22663[/tex]

Answer:

Step-by-step explanation: !!DISCLAIMER IM NOT ALWAYS THE SMARTEST BUT IM PRETTY SURE THIS IS RIGHT!

!well what I did. You know that 60 minutes=one hour. So I put 2 & 1/2 over 60.

Make 2 & 1/2 a improper fraction=5/2.

So 5/2 over 60

Then divide. 5/2 divided by 60 ( which is 60/1)

Then leave change flip, meaning leave the 5/2 change the division sign to multiplication, and flip, which you would flip 60/1 to 1/60

So we have 5/2 times 1/60. Multiply across. 5 times 1= 5. 2 times 60=120

So we have 5/120

Now we simplify 120 divided by 5 = 24. And 5 divided by 5 = 1

So 1/24
