Answer:
Hence the correct option is option b) Yes, the upper level of one standard deviation is 72.
A score of 74 is not within one standard deviation of the mean.
Step-by-step explanation:
Here the given details are,
Mean = 68
SD = 4
Distribution is normal.
Z-score for x = 74 is given as below:
So, the score of 74 is 1.5 standard deviations from the mean.
Therefore the score is not lies between 64 and 72.
Yes, the upper level of one standard deviation is 72.
The higher the percentage, the steeper the grade and the steeper the hill. This warning is issued so drivers are more careful (otherwise they would probably get into more accidents).

The up pinned pic is of inverse variation typed answer.. If u want word problem type answer here are the steps (EVEN IF THE STEPS ARE DIFFERENT ANSWERS REMAIN SAME)
Step-by-step explanation:
Mass of wire from 22cm = 374g
Mass of wire from 1 cm = 374÷22 = 17g
Mass of wire from 13 cm = 13×17 = <u>2</u><u>2</u><u>1</u><u> </u><u>g</u>
Answer:
Multiplication property of equality
Step-by-step explanation:
The multiplication property of equality states that if x = 1, then you can multiply both sides by the same number and both sides will stay equal to each other. Therefore, if x = y, then you can multiply both sides by the 3 to make 3x = 3y and they will still be equal to each other.

Answer:
The general relation about a geoemtric sequence is

For the first sequence, we have


Which is a system of equations. We can isolate a variable in the first equation to replace that expression into the second equation.


![r^{2}=\frac{147}{3}\\ r=\sqrt[2]{49}\\r=7](https://tex.z-dn.net/?f=r%5E%7B2%7D%3D%5Cfrac%7B147%7D%7B3%7D%5C%5C%20%20r%3D%5Csqrt%5B2%5D%7B49%7D%5C%5Cr%3D7)
Now, we replace this value to find the other one

Therefore, the explicit rule function is

Now, we use the same process for the second sequence.

The second equation is

Now, we solve the following expression

We solve for 

Then

Therefore, the function that models the second sequence is

Notice that
is the dependent variable and
is the independent variable.
