The Answer is 94.2 cubic inches
1 lemon to 2 waters will be proportional to what he Brandon needs so:
1 lemon / 2 water = x lemon / 12 water
Multiply by 12
And you get (1/2)*12 which is 6=x lemons
He needs 6 cups of lemons
Answer:
JK got 30 answers correct on a 50 item test.
Step-by-step explanation:
It is given that:
Total items on test = T = 50
Fraction of total items that were answered correctly = 3/5
We simply have to multiply the total number of questions by the fraction of correct answers.
So,
The correct answered number of items are:
Hence,
JK got 30 answers correct on a 50 item test.
To solve for proportion we make use of the z statistic.
The procedure is to solve for the value of the z score and then locate for the
proportion using the standard distribution tables. The formula for z score is:
z = (X – μ) / σ
where X is the sample value, μ is the mean value and σ is
the standard deviation
when X = 70
z1 = (70 – 100) / 15 = -2
Using the standard distribution tables, proportion is P1
= 0.0228
when X = 130
z2 = (130 – 100) /15 = 2
Using the standard distribution tables, proportion is P2
= 0.9772
Therefore the proportion between X of 70 and 130 is:
P (70<X<130) = P2 – P1
P (70<X<130) = 0.9772 - 0.0228
P (70<X<130) = 0.9544
Therefore 0.9544 or 95.44% of the test takers scored
between 70 and 130.
