Answer:
d. 0.538
Step-by-step explanation:
Given information.
Standard deviation is 4.3
Random sample of 10
Consider the following calculations
P (sample mean is within 1 month of population mean)=
P(-1*sqrt(10)/4.3 <Z<sqrt(10)/4.3)=P(-.735<Z<0.735)
=0.538
Answer:
f(x) = x^2 - 3x - 28
Step-by-step explanation:
The root -4 corresponds to the factor (x + 4); the root 7 corresponds to (x - 7). The equation is thus f(x) = (x + 4)(x - 7) = x^2 - 3x - 28, or
f(x) = x^2 - 3x - 28
To find the amount he ate we just add the fractions:
3/8 +1/2 = 7/8 or 0.875
