Answer:

You will earn $323.4 per week

Step-by-step explanation:

We are given:

Cost per hour = $13.20

Number of hours you work each week = 24.5 hours

We need to find how much money do you earn per week.

<em>Amount of money you earned per week = Cost per hour * Number of hours worked</em>

Amount of money you earned per week = 13.20 * 24.5

Amount of money you earned per week = 323.4

So, you will earn $323.4 per week

A college student borrows $2,000 for 9 months to pay for a semester of school. If the interest is $123.75, find the monthly paym
juin [17]

Total amount borrowed by college student = $ 2,000

Total interest paid = $123.75

Total amount the student has to pay = $2,000 + $123.75

= $2123.75

Total duration for which the amount is borrowed = 9 months

Total amount he has to pay back in 1 month = $2123.75 \div 9

= $235.9

Therefore, Amount he has to pay in 1 month = $235.9

Although cities encourage carpooling to reduce traffic congestion, most vehicles carry only one person. For example, 64% of vehi
ira [324]

Answer:

a) 0.7291 is the probability that more than half out of 10 vehicles carry just 1 person.

b) 0.996 is the probability that more than half of the vehicles  carry just one person.    

Step-by-step explanation:

We are given the following information:

A) Binomial distribution

We treat vehicle on road with one passenger as a success.

P(success) = 64% = 0.64

Then the number of vehicles follows a binomial distribution, where

P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 10

We have to evaluate:

P(x \geq 6) = P(x =6) +...+ P(x = 10) \\= \binom{10}{6}(0.64)^6(1-0.64)^4 +...+ \binom{10}{10}(0.64)^{10}(1-0.79)^0\\=0.7291

0.7291 is the probability that more than half out of 10 vehicles carry just 1 person.

B) By normal approximation

Sample size, n = 92

p = 0.64

\mu = np = 92(0.64) = 58.88

\sigma = \sqrt{np(1-p)} = \sqrt{92(0.64)(1-0.64)} = 4.60

We have to evaluate the probability that more than 47 cars carry just one person.

P(x \geq 47)

After continuity correction, we will evaluate

P( x \geq 46.5) = P( z > \displaystyle\frac{46.5 - 58.88}{4.60}) = P(z > -2.6913)

= 1 - P(z \leq -2.6913)

Calculation the value from standard normal z table, we have,  

P(x > 46.5) = 1 - 0.004 = 0.996 = 99.6\%

0.996 is the probability that more than half out of 92 vehicles carry just one person.
