Answer:
Total variable costs for the summer at each price:
a. = $10,185
b. = $5,820
c. = $1,455
Step-by-step explanation:
a. 35 lawns per week x 12 weeks x $24.25 variable cost
= 35 * 12 * $24.25
= $10,185
b. 20 lawns per week x 12 weeks x $24.25 variable cost
= 20 * 12 * $24.25
= $5,820
c. 5 lawns per week x 12 weeks x $24.25 variable cost
= 5 * 12 * $24.25
= $1,455
d. The variable cost, as can be seen from above, changes based on the volume of activity or production. The number of lawns influenced the cost, since the other indexes are the same in each case.

Use the range rule of thumb to
identify the range of values for usual numbers of bumper stickers.
</span>
<span>The
maximum usual value is 3.5.</span>
<span>max: μ + 2σ = 0.578 + 2(1.462161414) =
3.502322828</span>
<span>The
minimum usual value is 0.</span>
<span>min: μ – 2σ = 0.578 – 2(1.462161414) =

Is it unusual for a car to have
more than one bumper sticker? Explain.
</span>
No, because the probability of
having more than one bumper sticker is equal to 0.120 that is greater that 0.05

Answer:
Step-by-step explanation:
Notice that ∠7 is the vertical angle to 151°.
Vertical angles have the same measure.
So, ∠7 is <em>also</em> 151°.
Our answer is 151°.
And we're done!
3x < -9 means x < -3
The line would be an open circle on -3 and shaved to the left.
