A stadium has direct staffing costs of $108,000. Overhead costs (social security, medicare, worker's compensation, etc.) cost the stadium an additional 15%. What is the total staffing cost?
9514 1404 393
Answer:
$124,200
Step-by-step explanation:
We have ...
staffing cost = (direct cost) + 0.15·(direct cost)
staffing cost = (direct cost) · 1.15 = ($108,000)(1.15)
staffing cost = $124,200

After 100 spins, Lincoln calculated the probability that he would spin a prime number to be 0.35. Using the
spinner, what is the theoretical probability of spinning a prime number?
An 15
Given:
Total number of spins = 100
Probability that he would spin a prime number to be 0.35.
To find:
The theoretical probability of spinning a prime number.
Solution:
Total numbers from 1 to 100 = 100
Total prime numbers from 1 to 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
So, the prime numbers from 1 to 100 = 25
Now, the probability of spinning a prime number is
[tex]\text{probability}=\dfrac{\text{Total prime numbers from 1 to 100}}{\text{Total numbers from 1 to 100}}[/tex]
[tex]\text{probability}=\dfrac{25}{100}[/tex]
[tex]\text{probability}=0.25[/tex]
Therefore, the theoretical probability of spinning a prime number is 0.25.

tarting at elevation zero, Zen climbs to an elevation of 4,646.4 feet to reach the Cragway Trail. From there, he hikes up another 1,817.6 feet to the Calloway Peak Summit, the highest point on Grandfather Mountain. Based on these numbers, the Calloway Peak Summit is at a height of
feet.
On his return trip, Zen descends from the Calloway Peak Summit to an elevation of 2,402.5 feet, arriving at the Flat Rock Junction. So, the elevation at Flat Rock is
feet.
Answer:
Calloway Peak is 6,464 Feet. And Flat Rock is 4061.5 Feet
Step-by-step explanation:
For Calloway Peak Started at 0 so 4646.4+1817.6=6,464
Zen then descends which means he walked back down 2402.5 feet.
To find Flat Rock you subtract the height of Calloway Peak by 2402.5 the amount that he walked back down to get how tall Flat Rock is in Feet
6464-2402.5=4061.5 Feet
So Flat Rock is 4061.5 Feet tall.

Because they took the correct steps to answer the equation.They also got the right answer (-2).
At the begining they added 4 to both sides (to cancel out the 4)
C would be wrong because they subtracted 4 from a negative four and this does NOT cancel it out.
