Answer:
15.87%
Step-by-step explanation:
First thing here is that we calculate the z-score which corresponds to 76
mathematically;
z-score = (x-mean)/SD
mean = 71 and SD = 5
plugging these values, we have;
z = (76-71)/5 = 5/5 = 1
Now, we want to firstly get the probability that we have a student shorter than 76 inches
The probability we want to calculate is P(z<1)
we can get this using the z-score table directly
That would be 0.15866
In percentage that is 15.866% which is 15.87% to the nearest tenth
X (unknown number at first is 28) is the number 28.
28/7=4. 2(28) divided by 7= is also 56 divided by 7.
Which is 8. 8 is the final answer.

Answer:
<h2>Independent variable: Weight of Onions.</h2><h2>Dependent variable: Total Cost.</h2>
Step-by-step explanation:
The given table is about the weight of onions in pounds and the total cost.

So, to put it in a sentence: The weight of onions determines the total cost.
Do the (68+7) = 75 then do 75+93=168
