Answer:
x=5
Step-by-step explanation:
F(x)=-3x+21,
f(x)=6 = -3x+21
6 = -3x+21
Subtract 21 from each side
6-21 = -3x+21-21
-15 = -3x
Divide each side by -3
-15/-3 = -3x/-3
5 = x
Answer:
Step-by-step explanation:
Given that there is a t distribution with 7 degrees of freedom.
P(-1.29 < t < 1.29)=1-0.2380
=0.7620
b) Now there is a different t distribution with 18 df.

Answer:
y = -x + 4
Step-by-step explanation:
The point-slope formula for a straight line is
y – y₁ = m(x – x₁)
x₁ = -1; y₁ = 5; m = -1 Substitute the values
y – 5 = -1(x + 1) Remove parentheses
y – 5 = -x - 1 Add 5 to each side
y = -x + 4
The graph is a straight line with a y-intercept at y = +4 and a slope = -10/10
= -1.
