Answer:
and
.
Step-by-step explanation:
To this relation be a function, the horizontal coordinates can't be equal. So, let's find the value of
that makes those coordinates equal.

Using the null factor property, we have

Therefore, the given relation is not a function when
and
.
Just divide 8 by 2 and you'll get 4
Each container is 2 ounces so do 75 times 4 and you'll get 300 calories
Z = (x - mean) / SD = (79 - 70) / 3 = 3
<span>P (Z > 3)? = 1 - F (z) = 1 - F (3) = 0.00135</span>
16.4041995 rounding that would be 16 rounding to the nearest hundredth would be 16.400 (or 16.4) yards.
The sum is -12. hope this helps you
