Answer:
If $300 is 200%, half of that would be 100%. Thus, $150 is the correct answer.
Step-by-step explanation:
The area of the given composite figure is 34 square feet
<h3>Area of rectangle</h3>
Area of the rectangle = length * width
<h3>Get the area of the given composite figure</h3>
For the composite figure shown:
Area = (8*3) + (2 * 5)
Area = 24 + 10
Area = 34 square feet
Hence the area of the given composite figure is 34 square feet

Answer:
a)= 2
b) 6.324
c) P= 0.1217
Step-by-step explanation:
a) The mean of the sampling distribution of X`1- X`2 denoted by ux`-x` = u1-u2 is equal to the difference between population means i.e = 2 ( given in the question)
b) The standard deviation of the sampling distribution of X`1- X`2 ( standard error of X`1- X`2) denoted by σ_X`1- X`2 is given by
σ_X`1- X`2 = √σ²/n1 +σ²/n2
Var ( X`1- X`2) = Var X`1 + Var X`2 = σ²/n1 +σ²/n2
so
σ_X`1- X`2 =√20 +20 = 6.324
if the populations are normal the sampling distribution X`1- X`2 , regardless of sample sizes , will be normal with mean u1-u2 and variance σ²/n1 +σ²/n2.
Where as Z is normally distributed with mean zero and unit variance.
If we take X`1- X`2= 0 and u1-u2= 2 and standard deviation of the sampling distribution = 6.324 then
Z= 0-2/ 6.342= -0.31625
P(-0.31625<z<0)= 0.1217
The probability would be 0.1217

Answer:
the 40 ounce bag is better
Step-by-step explanation:
this is because if you multiply $1.10 by 4 you get $4.40. This means that the 40 ounce bag is cheaper
