An integer is a whole number, and a decimal is not a whole number, it's like a fraction.
Answer:
She should walk for 12 minutes
Answer:
<h2>B. (-2, 3)</h2>
Step-by-step explanation:
Given two coordinates (x₁, y₁) and (x₂, y₂), the coordinate of their midpoint is equivalent to X = (x₁+x₂)/2 and Y = (y₁+y₂)/2.
Given the coordinate of Sally's house and her school to be (5, −1) and (−9, 7) respectively, the midpoint of Sall's house and school is expressed as shown;
from the coordinates, x₁ = 5, y₁ = -1, x₂ = -9 and y₂ = 7
X = (5+(-9))/2
X = 5-9/2
X = -4/2
X = -2
Y = -1+7/2
Y = 6/2
Y = 3
The coordinate of the midpoint of Sally's house and school will be expressed as (X, Y) which is equivalent to (-2, 3).
Answer:
A negative correlation
Step-by-step explanation:
This correlation coefficient indicate that there exist a weak negative correlation between the runner’s time and the speed.
This relation is negative because the correlation coefficient is negative
