Answer: X x (X^2-5)
Step-by-step explanation:
Answer:
Step-by-step explanation:
(-3x+x)=kx+9
-2x=kx+9
-2x-kx=9
x(-2-k)=9
x=9/(-2-k)
We have the mean, μ = 20 and the standard deviation, σ = 4
X ≈ N(20, 4²)
We want P(X<15)
Standardising gives
P(X<15) = P(Z<
)
P(X<15) = P(Z< -1.25) ⇒ When the value of the z-score is negative, we will read the value of z<1.25 on the z-table then subtract the answer from 1
P(X<15) = 1 - P(Z<1.25)
P(X<15) = 1 - 0.8944
P(X<15) = 0.1056
Hence, the probability that pizza takes less than 15 minutes to be delivered is 0.1056 = 10.56%
Answer:
Step-by-step explanation:
First, find the slope of the line:
The formula for finding the slope is:
Plug in the points:
= =
So now the equation is y = x + b
Now solve for b by plugging in one of the points:
(2,7)
y = x + b
7 = 2 + b
7 = + b
b =
So the equation will be
