According to the Oxnard College Student Success Committee report in the previous year, we believe that 25% of students struggle in their classes because they don't spend more than 8 hours studying independently outside of a 4-unit class. For this year, you would like to obtain a new sample to estimate the proportiton of all Oxnard students who struggle in their classes because they don't study enough outside of the classrooms. You would like to be 99% confident that your estimate is within 1% of the true population proportion. How large of a sample size is required? Do not round mid-calculation

Forty percent of all high school graduate work during the summer to earn money for college tuition for the upcoming fall term. Assuming a binomial distribution, if 6 graduates are selected at random, what is the probability that none of the graduates have a summer job

Answers

Answer:

[tex]0.0467[/tex] is the probability that none of the graduates have a summer job

Step-by-step explanation:

Here

P [tex]= 0.40[/tex] and n [tex]= 6[/tex]

Probability that none of the graduate gets job

this means that x = 0

P (x = 0) [tex]= ^6C_0 * (0.40)^0 * (0.60)^6[/tex]

P (x = 0) [tex]= 0.0467[/tex]

Answer:

y=4/5x-4

Step-by-step explanation:

use formulas (y2-y1)/(x2-x1) and y=mx+b

slope (y2-y1)/(x2-x1):

(8-0)/(5-(-5))

=8/10

=4/5

equation (y=mx+b):

0=4/5(5)+b

0=4+b

A local pizza shop has a membership program for frequent buyers. The membership costs $20 per month and members get a discounted price of $1.50 per slice of pizza. Shandra purchased a membership to this pizza shop. How much would Shandra have to pay the pizza shop if she bought 5 slices of pizza this month? What would be the monthly cost for x slices of pizza?

Answers

Answer:

Shandra would pay $27.50 for 5 slices

Cost = 20+1.50x

Step-by-step explanation:

Given

[tex]Membership = \$20[/tex]

[tex]Discounted\ Price = \$1.50[/tex] per slice

Solving (a): Cost of 5 slices

Represent the total price with y and the number of slice with x.

So, we have:

[tex]y = Membership + Discounted\ Price * x[/tex]

This gives:

[tex]y = 20+ 1.50* x[/tex]

In this case: x = 5.

So, we have:

[tex]y = 20+ 1.50* 5[/tex]

[tex]y = 20+ 7.50[/tex]

[tex]y = 27.50[/tex]

Shandra would pay $27.50 for 5 slices

Solving (b): Cost of x slices

This has been solved in (a).

[tex]y = 20+ 1.50* x[/tex]

[tex]y = 20+1.50x[/tex]

Hence, the cost of x slices is 20+1.50x

Do the same to the other equation

5x+3(y+4x)

Set an equation that will let you add their like terms.

y+4+3y+5+5x+3y+12x

I'm going to add like terms with the y

592.83 ft^2

Step-by-step explanation:

First estimate the area of the rectangle:

Area rectangle = Base x Height = 20 * 36 = 720 ft^2

and then subtract from it the area of a semi-circle of radius 18/2 = 9 ft

Using the formula for the semicircle's area:

Semi-circle's area= pi * R^2 / 2 = 3.14 * 9^2 / 2 = 127.17 ft^2

Such gives us:

720 ft^2 - 127.17 ft^2 = 592.83 ft^2
