Paul and Cindy own different pizza shops. Paul makes 12 pizzas the first day and 6 pizzas each day after that. Cindy makes 16 pi

pishuonlain [190]

The right answer is Option C.

Step-by-step explanation:

Given,

Pizzas made by Paul on first day = 12

Pizzas made each day after that = 6

Let,

p represent the number of pizzas made after first day.

Total pizzas = 6p + 12

Number of days = 8 because first day 12 pizzas are made

Total pizzas = $6(8)+12=60$

Pizzas made by Cindy on first day = 16

Pizzas made each day after that = 4

Total pizzas = 4p + 16

Total pizzas = $4(8)+16=48$

Paul has made more pizzas after 9 days. He has made 60 pizzas.

The right answer is Option C.

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

Given the lengths of the sides, state if the triangle is acute, obtuse, or right. 9, 36, and 41 This is a(n) blank triangle.

Agata [3.3K]

Answer:

This is an obtuse triangle

Step-by-step explanation:

Pythagoras theorem is used to determine if a triangle is right, acute or obtuse

If the sum of squares of two shorter lengths is greater than the square of third side then the triangle is an acute triangle.

If the sum of squares of two shorter lengths is less than the square of third side then the triangle is an obtuse triangle.

If the sum of squares of two shorter lengths is equal the square of third side then the triangle is a right triangle.

so,

$(41)^2 = (36)^2+(9)^2\\1681 = 1296+81\\1681>1377$

As 1681>1377, the given triangle is an obtuse triangle ..
