Answers
The r-value that represents the strongest correlation is (a) - 0.83
How to determine the strongest correlation?
The correlation coefficient has its value to be from -1 to 1
The closer the value to 1 or -1, the stronger the correlation
-0.83 is closer to -1 than the other values closer to 1 or -1
Hence, the r-value that represents the strongest correlation is (a) - 0.83

Answer:
–0.83
Step-by-step explanation:
In regression analysis, the coefficient of correlation is a statistic which indicates an association between the independent variables and the dependent variable. The coefficient of correlation is represented by "r" and it has a range of -1 to 1. The nearer the r-value to -1 or 1 the better the correlation.

The answer to this question would be: 5 second
In this question, you are given the initial distance (300ft), car velocity(48ft/s) and the final distance(60ft). You are also given the equation to calculating the distance, so this question should be easier. The question is when the time where the distance is 60 ft. So the answer would be:
distance= 300-48t
60 = 300ft- 48t
48t= 300- 60=240
t= 5

A boxplot is a graph that displays the middle 50 percent of a data set, using the minimumvalue, first quartile, median, third quartile, and maximumvalue.
Explanation:
A boxplot is a type of graph that visually displays the middle 50 percent of a data set. It is constructed using the minimum value, first quartile, median, third quartile, and maximum value.
The firstquartile is the median of the lower half of the data, while the third quartile is the median of the upper half.
The whiskers extend from the box to the minimum and maximum values within a certain range. The range can vary, but it's often defined as 1.5 times the IQR. Data points beyond the whiskers are considered outliers and are typically marked individually.

Answer:
The sum of first eighteen terms of the arithmetic sequence is
Option B is correct option.
Step-by-step explanation:
We need to find the sum of the first eighteen terms of the arithmetic sequence whose nth term is an = 15 + 8n
The formula used to calculate sum of arithmetic sequence is:
Finding a₁ by putting n=1
We have
Finding 18th term n=18
So, the sum of first eighteen terms of the arithmetic sequence is:
So, the sum of first eighteen terms of the arithmetic sequence is
Option B is correct option.

Good morning Brainiac
m=n-2
m+4n=8
We need to solve m=n-2 for m
Substitute n-2 for m in m+4n=8
m+4n=8
n-2+4n=8
5n-2=8
Add 2
5n-2+2=8+2
5n=10
Now divide both sides by 5 so we can find the value for n
5n/5=10/5
n=2
Now substitute 2 for n in m=n-2
m=n-2
m=2-2
m=0
