PLEASE HELP!! Trevor is writing a paper that must be 50,000 words long. He had already written 23,210 words. Write an inequality
almond37 [142]

Answer:

50,000 ≤ 23,210 + 5x

x = Average number of words per week

Step-by-step explanation:

Start off with 50,000 because that's how many words the paper needs to have.

Use "≤" because Trevor needs to write at least 50,000 words. (He can write more).

Trevor already wrote 23,210 words plus x words per week for 5 weeks.

(Solving for x will help you find the average number of words Trevor must write per week for 5 weeks).

Arachnophobia is the fear of spiders. People with arachnophobia suffer to different degrees, but they tend to react intensely to
zepelin [54]

Answer:

1. The null hypothesis is that there is no difference between the population means (in other words, there is no treatment effect).

2. The<u> alternative hypothesis</u> is that at least one of the population means is different from another (in other words, there is an effect Of at least one Of the treatments).

Step-by-step explanation:

In a statistical analysis, the statistician shares his participants into several groups and administers treatments to them. After administering the treatment, he might want to compare the values obtained to see if there is a difference. If he accepts the null hypothesis as true, that means that there was no difference between the population means. This can also be taken to mean that the result had no difference among the groups.

But if the alternative hypothesis was true, that means that the population means were not all equal and so, there was an effect from the treatment administered.

Alekssandra [29.7K]

Answer:

36

Step-by-step explanation:

This is the fraction we use to solve this problem \frac{Ounces}{Flour}

Fractions are \frac{8}{3} and \frac{96}{x}

We now ask ourselves

8 * x = 96\\x = 12

Since whatever we do to the numerator we have to to the same to the denominator, we multiply 3 and 12

3 * 12 = x\\x = 36

Hope this helps!
