Answer: The proportion that will qualify is 0.0314 or 3.14%.
First, we need to find the z-score of a time of 128 seconds. To do this, we find the difference of the mean and score and divide by the standard deviation.
(128 - 141) / 7 = -1.86
Now, use a standard normal distribution table to determine the percent below a z-score of -1.86. That value is 0.0314 or 3.14%.
Answer:
the answer is the first one, Cara multiplied only 4 and 7 together and did not multiply 4 and 13
Step-by-step explanation:
if you look through the question you can see that Cara evaluated the (-4)^2 correctly because a negative multiplied by a negative gives you a positive thus (-4)*(-4)= 16, then next you can see that Cara subtracted 2 from 6 correctly because (6-2)= (4), and last but not least Cara did multiply 2 by 4 correctly because 2*4 or 2(4) =8 so as you can see the answer is the first one
1 pound of bread contains 
cups of cinnamon.
<h3><u>
Solution:</u></h3>
Given that , In 
pound of a banana bread, there is 
cup of cinnamon
<em><u>To find:</u></em>
Amount of cinnamon per pound in bread
Let "n" be the cinnamon per pound present in bread
pound of banana bread ⇒ cup of cinnamon
Then, 1 pound of bread ⇒ n cups of cinnamon
Now, let us use criss cross method (i.e. multiplying the diagonal ordered terms and equating them)
Hence, 1 pound of bread contains cups of cinnamon.
F(x)=x^2+x+5
then
F(3) would be the function evaluated at x=3, or 17.
anytime you see F(3) it is just whatever formula you are looking at evaluated when the variable is equal to 3.
