Answer:
a) 
And replacing we got:
b) 
And using the normal standard distribution table and the complement rule we got:
Step-by-step explanation:
From the info given if we define the random variable X as "amount of saturated fat in a daily serving of a particular brand of breakfast cereal " we know that the distribution of X is given by:
Part a
For this case the sample size would be n =30 and then the distribution for the sample mean would be given by:
And replacing we got:
Part b
We want to find this probability:
And we can use the z score formula given by:
And replacing we got:
And using the normal standard distribution table and the complement rule we got:
Establish two right triangles, both with the height of the pole, h.
Call x the distance from the pole to one stake. Then the distance from the other stake to the pole is 6 -x.
Apply Pytagora's equation to both triangles.
1) h^2 = 7^2 - x^2
2) h^2 = 8^2 - (6-x)^2
Eaual 1 to 2
7^2 - x^2 = 8^2 - 6^2 +12x -x^2
12x = 7^2 -8^2 +6^2 = 49 -64 + 36 = 21
x = 1.75
Substitue x-value in 1
h^2 = 49 - (1.75)^2 = 45.94
h = sqrt(45.94) = 6.78
Answer: option d.
Then angle D is 67 as all sides and measurements are equal on a parallelogram.

Answer:
f(2) = - 16
Step-by-step explanation:
Given
f(x) = - 
To evaluate f(2) substitute x = 2 into f(x)
f(2) = - 
= - 16
