During a walkathon, Team A walked a total of 6x+12 miles and Team B walks a total of 4x-7 miles. What is the difference in miles
1 answer:
The right answer is Option D.
Step-by-step explanation:
Distance of Team A = 6x+12
Distance of Team B = 4x-7
Difference between two teams means subtraction, therefore, subtracting the distance of Team B from Team A;
Combining alike terms;
The difference between two teams is 2x+19.
The right answer is Option D.

Answer:
Correlation coefficient ≈ 0.9445
This indicates that the weight of a student increases as the height of the student increases.
Step-by-step explanation:
The rest of the question is the following table
value of x (<u>height</u>) are 58, 59, 60, 62, 63, 64, 66, 68, 70
Value of y (<u>weight</u>) are: 122, 128, 126, 133, 145, 136, 144, 150, 151
=======================================================
To calculate the correlation coefficient we will use the following form:
So, n (the number of terms) = 9
∑x = 570, ∑y= 1236, ∑ x²= 36234, ∑ y²= 170694 and ∑xy=78617
So, the correlation coefficient =
∴ r = 0.9445
So, weight of a student increases as the height of the student increases.
