Considering that it has a higher coefficient of variation, the distribution of cell phone bills at Smithtown South High School is more spread out.

<h3>What is the coefficient of variation of a distribution?</h3>

The coefficient of variation for a distribution is given by the standard deviation of the distribution divided by the mean of the distribution. The higher the coefficient, the more spread out the distribution is.

For the distributions in this problem, the coefficients are given as follows:

  • Smithtown North High School: 11/183 = 0.0602.
  • Smithtown South High School: 21/181 = 0.1160.

Due to the higher coefficient of variation, the distribution of cell phone bills at Smithtown South High School is more spread out.

In 2020, there were about 260 million gas powered cars on the road. This number isexpected to decrease at a rate of 1.1% per yea
Amanda [17]

This is an equation of exponential decay

y(t) = a b^ t where a is the initial amount

b is the decay factor

t is the time in years

b is found by taking 1 and subtracting the percent it decreases in decimal form

Letting t =4

y(t) = 260 million * ( 1- .011) ^ 4

=248.7473796 million

=24874737.96

Rounding to a whole number

= 24874738

10c - cd + d^3 (if c = -6 and d= 2)
mash [69]

The required simplified solution of the given expression is -40.

Given that,
To determine the simplified solution of the given expression 10c - cd + d³ at c = -6 and d = 2.

<h3>What is simplification?</h3>

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
= 10c - cd + d³

Substitute the values,
= -60 + 12 + 8
= -40

Thus, the required simplified solution of the given expression is -40.

Answer:

Note that PQ + QR = PR:

Once:  

PR = 15x-11\\PQ=3x+6

PQ + QR = PR\\\\(3x+6)+QR=(15x-11)\\\\QR=(15x-11)-(3x+6)\\\\QR=15x-11-3x-6\\\\QR=12x-17\\

Therefore, the answer is letter B
