Answer:
d. The average is equal to 12 ounces.
Step-by-step explanation:
In this problem, the drink filling machine must be perfectly calibrated at 12 ounces since it needs to be shut down in cases of overfilling (mean > 12 ounces) and underfilling (mean < 12 ounces). Therefore, the correct approach would be to test if the mean is 12 ounces and the correct set of hypothesis would be:
The correct alternative is d. The average is equal to 12 ounces.
<u>ANSWER</u>
<u>EXPLANATION</u>
The given compound inequality is
We need to simplify this inequality so that we can obtain x standing alone between the inequality signs.
We add 6 through out the inequality.
This simplifies to:
We now divide through by -3 and reverse the inequality sign.
We now simplify to get:
First we need to find how much the annual global seafood consumption (agsc) rose, which is 16 pounds
now, we find how much percent of 22 is 16. we put it through a calculator and, rounded to the nearest tenth, get 72.7%
so, the percent increase is 72.7%
The sum of two numbers is zero.
x + y = 0
y = -x
<span>Twice the smaller number subtracted from 3 times the larger number is 10.
Let x represent the larger number and y represent the smaller number.
Twice the smaller number: 2y
3 times the larger number: 3x
</span>Twice the smaller number subtracted from 3 times the larger number is 10.
3x - 2y = 10
-2y = -3x + 10
y = 3/2 x - 5
The equations are:
y = -x
y = 3/2 x - 5
The answer is the first choice.
