Answer:
the distance between A and C
Answer:
B(-1,-3)
Step-by-step explanation:
let the coordinates of B be (x,y)
Mid point of AB = (x₁+ x₂/2, y₁+y₂ /2)
= (-3 +x/2 , -5+y/2)
Mid point of AB is M(-2,-4)
(-3 +x/2 , -5+y/2) = (-2, -4)
-3 + x /2 = -2 ; -5+y/2 = -4
-3 + x = -2 * 2 ; -5 + y = -4 * 2
-3 + x = -4 ; -5 + y = -8
x = -4 +3 ; y = -8 +5
x = -1 ; y = -3
B(-1,-3)
Answer:
.25
Step-by-step explanation:
2 eggs are pink
4 eggs are purple
2 eggs are orange
-----------------------
8 total eggs
P( orange) = orange eggs/ total eggs
= 2/8
= 1/4
= .25
Answer:
Hence, the data provides convincing evidence that a linear relationship exists between hours of sleep observed and academic performance as measured by GPA.
Step-by-step explanation:
Given the data:
Sleep (hrs) 9 8.5 9 7 7.56 7 5.5 6 8.5 6.5 8
GPA 3.8 3.3 3.5 3.6 3.4 3.3 3.2 3.2 3.2 3.4 3.6 3.1 3.4 3.7
The scatter plot shows a positive linear trend. With the correlation Coefficient depicting a R value of 0.56. The residual plot also depicts a a randomly scattered values of the residual values. Similarly, a plot of the normal values of residuals
Prime numbers are numbers that can be divided without a remainder. So 2181 is divisible by 3 and 727 and there is no remainder.
