Answer:

Step-by-step explanation:

for inverse of f(x)=2x+2

x=2y+2

x-2=2y

(x-2)/2=y

therefore the inverse f(x)=(x-2)/2

The Farmer Supply is building storage building for fertilizer shaped top. The that has cylindrica base and cone county laws say

creativ13 [48]

Assuming ℎ1 = 11 feet and ℎ 2 = 3 feet, the storage of the facility is going to be 603 cubic feet, which is more than 576 cubic feet

The diameter of the building has been given as 8cm

radius = d/2 = 8/2 = 4

Maximum height = h1 + h2 = 14

Find the volume of the fertilizer that is containeed in both of the trucks

2(12x4x6) = 576 feet

From the height of 14 feets we have to assume

h1 = 11 ft,

h2 = 3 ft

<h3>How to solve for volume</h3>

$volume =\frac{1}{3} \pi r^{2} h2 + \pi r^{2} h1$

= 0.333*3.14*4²*3 + 3.14*4²*11

= 602.8 ft ≈ 603

Private nonprofit four-year colleges charge, on average, $27,293 per year in tuition and fees. The standard deviation is $7,235.

Natali5045456 [20]

Answer:

a) $X\sim(27293,(7235)^2)$

b) 0.1567

c) $P_{70}=31084.14$

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $27,293 per year

Standard Deviation, σ = $7,235

We are given that the distribution of cost of college is a bell shaped distribution that is a normal distribution.

a) Distribution of X

Let X be the cost for a randomly selected college. Then,

$X\sim (\mu, \sigma^2)\\X\sim(27293,(7235)^2)$

b) Probability that a randomly selected Private nonprofit four-year college will cost less than $20,000 per year.

$P( x < 20000) = P( z < \displaystyle\frac{20000 - 27293}{7235}) = P(z < -1.008)$

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

$P(x < 20000) = 0.1567$

c) 70th percentile for the distribution.

We have to find the value of x such that the probability is 0.7

$P( X < x) = P( z < \displaystyle\frac{x - 27293}{7235})=0.7$

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

$\displaystyle\frac{x - 27293}{7235} = 0.524\\\\x = 31084.14$

The 70th percentile for the distribution of college cost is $31,084.14
