The average rate of change between March 15 and June 15 will be given by:
(82.4-66.8)/(6-3)
=15.6/3
=5.2° F per month

Answer: C

Answer:

<h2>C. 5.2°F per month</h2>

Step-by-step explanation:

The average rate of change refers to the relation between these variables.

Specifically, this problem can be modeled by a linear function, where the slope is the average rate of change.

So, such rate can be defined as

r=\frac{y_{2}-y_{1}  }{x_{2} -x_{1} }

Where (x_{1} ,y_{1} ) is the first pair and (x_{2} ,y_{2} ) is the second one.

In this case, the first pair is (3,66.8) and the second pair is (6,82.4). Replacing these coordinates, we have

r=\frac{y_{2}-y_{1}  }{x_{2} -x_{1} }=\frac{82.4-66.8}{6-3}=\frac{15.6}{3}=5.2

Which is expressed in Fahrenheit.

Therefore, the average rate of change is 5.2 °F.

This can be interpreted as "The temperature changes +5.2 °F each month between March 15 and June 15".

Find three consecutive odd integers such that the sum of the 1st and 2nd number is 344
olga2289 [7]

Answer:

three consecutive odd integers are.

171, 173, 175

Step-by-step explanation:

Let x be the first term of odd integer,

Therefore, the second consecutive odd integers = x+2

Similarly, the third consecutive odd integers = x+4

Given:

The sum of the first term and second term is 344.

first term + second term = 344

Here first term is x and second term is x+2.

x+(x+2)=344

2x+2=344

2x=344-2

x=\frac{342}{2}

x=171

Therefore, the first odd integers is 171.

And the second consecutive odd integers = x+2=171+2=173

Similarly, the third consecutive odd integers = x+4=171+4=175

What is the answer to <br> √a³-7 + -4
Oksanka [162]

Answer:

√a^3−7-4

Step-by-step explanation:

Replace all occurrences of + − with a single −. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅ −1= −1

A set of quiz scores is shown in the histogram below. The mean of the data set is 20.2, and the (population) standard deviation
Neko [114]

Answer:

13

Step-by-step explanation:

As the mean is 20.2 and the standard deviation is 2.4

The range within the first standard deviation is

(17.8,22.6)

This means that we can safely use the range of (18,22) as we cannot confirm whether the other values fall within the range.

Within this range there are

2+3+4+3+1=13
