According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average of 66 in
Zolol [24]

Answer:

The probability that the person is between 65 and 69 inches is 0.5403

Step-by-step explanation:

Mean height = \mu = 66

Standard deviation = \sigma = 2.5

We are supposed to find What is the probability that the person is between 65 and 69 inches i.e.P(65<x<69)

Z=\frac{x-\mu}{\sigma}

At x = 65

Z=\frac{65-66}{2.5}

Z=-0.4

Refer the z table for p value

P(x<65)=0.3446

At x = 69

Z=\frac{69-66}{2.5}

Z=1.2

P(x<69)=0.8849

So,P(65<x<69)=P(x<69)-P(x<65)=0.8849-0.3446=0.5403

Hence the probability that the person is between 65 and 69 inches is 0.5403

Will it cost more to rent from Company A or Company B if "Ali" rents the bounce house for 3 hours? 5 hours? 10 hours?
a_sh-v [17]

Answer:

3 HOURS : company A costs more

5 HOURS : Cost is the same

10 HOURS : Company B costs more

Step-by-step explanation:

Company A :

Rental fee = $100

Hourly rate = $20

Company B:

Hourly rate = $40

Cost of renting a bounce house from each company for h hours ;

Company A:

Total cost = 100 + 20h

Company B:

Total cost = 40h

If h = 3

Company A:

100 + 20(3) = $160

Company B:

40(3) = $120

FOR h = 5;

Company A:

100 + 20(5) = $200

Company B:

40(5) = $200

FOR h = 10;

Company A:

100 + 20(10) = $300

Company B:

40(10) = $400
