We need 75 quarts of 3% butterfat milk. How much of 2% and 5% do we need to mix? (t = 2% and f = 5%)

A) t + f = 75

B) .02 t + .05 f = (.03 * 75)

B) .02 t + .05 f = 2.25


Solving for t and f:

t = 50 quarts of 2 % and

f = 25 quarts of 5%


Double-Check

50 * .02 = 1 quart of buttermilk

25 * .05 = 1.25 quarts of buttermilk


2.25 quarts divided by 75 quarts = 3 % buttermilk

fomenos

Answer: A.

H_0:p=0.12\\\\H_a:p

Step-by-step explanation:

Null hypothesis(H_0) : A statement describing population parameters as per the objective of the study. It usually takes "≤,≥,=" signs.  

Alternative hypothesis (H_a): A statement describing population parameters as per the objective of the study. It usually takes ">, <, ≠" signs.

Let p be the proportion of screens that will be rejected.

12 percent of the screens manufactured using a previous process were rejected at the final inspection.

(i.e. p= 0.12)

Objective of the study = whether the new process<em> reduces </em>the population proportion of screens that will be rejected

i.e. p< 0.12

So, the appropriate hypotheses to investigate whether the new process reduces the population proportion of screens that will be rejected:

H_0:p=0.12\\\\H_a:p

maxonik [38]

Step-by-step explanation:

figure of speech in which a character or speaker addresses someone who is absent. This could be a person they know or don’t know someone who is alive or dead, or someone who never existed at all. It might also be a non-human animal, an abstracted, but personified force, or even an object. Often, this technique is used when a speaker addresses a god or group of gods.

Apostrophe Examples

Twinkle, twinkle, little star, how I wonder what you are. ( ...

O holy night! ...

Then come, sweet death, and rid me of this grief. ( ...

O, pardon me, thou bleeding piece of earth. ( ...

Roll on, thou deep and dark blue Ocean – roll! ( ...

Welcome, O life!
