First You would divide both numbers by ten to get 15 and 25. Then you realize that both numbers are divisible by 5 so you divide both sides you then end up with 3 to 5 which is your answer.
-.75. 3÷4 = 75. put a negative sign beside it and it’ll be negative boom.
Answer:
slope= 0.52
Step-by-step explanation:
For American women
Mean (x) = 64 inches
Standard deviation (sx) = 2.7 inches
For American Men
Mean(ÿ) = 69.3 inches
Standard deviation (sy) = 2.8 inches
r = 0.5
Slope = ??
Husband height = Y
Wife height = X
the general equation of regression line
y = a + bx
The slope of the regression line is the linear correlation coefficient multiplied by the standard deviation for Y
b = r (sy/sx)
b = 0.5(2.8/2.7)
b = 0.52
The intercept a = ÿ - bx
a = 69.3 - 0.52(64)
a = 69.3 - 33.28
a = 36.02
The equation of the regression line y = a + bx
y = 36.02 + 0.52x
Option A: 
is the solution
Explanation:
The solution of the given inequality is the set of all the possible values of x.
The graph shows the number line in which the shaded region is from the right of -4 and the arrow of solution goes to infinity.
Also, There is a closed circle at the point -4.
This means that -4 is included in the solution set.
The solution to the inequality is the set of all the real values which are greater than or equal to -4.
Thus, the solution is x ≥ -4
Hence, the solution is
