Answer:
We need <em><u>1 cup</u></em> of sugar to make 16 cookies.
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
To solve this question we can use the <u>Rule of Three</u> technique to find out how many cups we would need for 16 cookies. We can use this technique because we are given three values and one variable and the two sets are a ratio of one another. The technique is shown in the picture below.
1 ⇒ 20 cookies
x ⇒ 16 cookies
We need <em><u>1 cup</u></em> of sugar to make 16 cookies.

Answer:
The probability that a person will get 17 or more right, if the person is truly guessing, is about 12.9%.
The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.
Step-by-step explanation:
The system of hypothesis fo this case are:
Null hypothesis:
Alternative hypothesis:
That's a upper right tailed test.
The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.
And this value allows to reject or not the null hypothesis.
If we reject the null hypotheis at the significance level. That indicates strong evidence against the null hypothesis, so you reject the null hypothesis.
If then we say that we fail to reject the null hypothesis at the significance level. That indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis.
