Answer:
4.42857142857 but since we are rounding to the nearest hundredth it would be 4.43
Step-by-step explanation:
You would add all the numbers together (7+4+2+6+4+5+3=31) then you would divide by the number or numbers there is (31 divided by 7= 4.42857142857) then round to the nearest hundredth (4.43000000000 = 4.3)
Answer:
The probability of finding an average in excess of 4.3 ounces of this ingredient from 100 randomly inspected 1-gallon samples of regular unleaded gasoline = P(x > 4.3) = 0.00621
Step-by-step explanation:
This is a normal distribution problem
The mean of the sample = The population mean
μₓ = μ = 4 ounces
But the standard deviation of the sample is related to the standard deviation of the population through the relation
σₓ = σ/√n
where n = Sample size = 100
σₓ = 1.2/√100
σₓ = 0.12
The probability of finding an average in excess of 4.3 ounces of this ingredient from 100 randomly inspected 1-gallon samples of regular unleaded gasoline = P(x > 4.3)
To do this, we first normalize/standardize the 4.3 ounces
The standardized score for any value is the value minus the mean then divided by the standard deviation.
z = (x - μ)/σ = (4.3 - 4)/0.12 = 2.5
To determine the probability of finding an average in excess of 4.3 ounces of this ingredient from 100 randomly inspected 1-gallon samples of regular unleaded gasoline = P(x > 4.3) = P(z > 2.5)
We'll use data from the normal probability table for these probabilities
P(x > 4.3) = P(z > 2.5) = 1 - P(z ≤ 2.5) = 1 - 0.99379 = 0.00621

A)
C(102) = 102^2 – 400 = 10004
</span>C(100) = 100^2 – 400 = 9600
average rate of change = (10004<span>- 9600)/(102 - 100) = 404/2 = 202

C' = 2x = 2 (100) = 200
Answer:
2(28)=23+x
Step-by-step explanation:
There are 28 students and each student needs two brownies. You have to multiply 28 by 2 so you will have to total number on one side.
On the other you need to have the number of brownies you have at the moment and x for the number you need to bake. You want to add them because you will need to put those numbers together to get the number on the opposite side.
28x2=56 so 56=23+x. Subtract the 23 from both sides to get 33=x. x=33
To check plug 33 into x to get 2(28)=23+33. 56=23+33. 56=56
you need 33 more brownies.
So the equation would be 2(28)=23+x.
Hope that helps.
