Answer: -23
Step-by-step explanation:
Answer:7 Feet below ground
Step-by-step explanation:
1st: Since it says our hole is dug down 8ft to begin with we can start with x=-8
2nd: After a short break, it says we dug down another 3 feet which is -8-3=-11 which shows we are 11 feet below ground where the negative number showcases we are below ground level.
3rd:
After this we are shown a tractor accidentally fills in the hole with 4ft of dirt which signifies that we lose some of our holes height below ground so we would add four: -11+4=-7 this shows that we are finally seven feet below ground.
Answer:
N(L) = 20
The expected number of left handed people is 20.
Step-by-step explanation:
Given;
Percentage of left handed people P(L) = 10%
Total number of selected people N(T) = 200
The Expected number of left handed people N(L) is;
N(L) = Total number of selected people × Percentage of left handed people/100%
N(L) = N(T) × P(L)/100%
Substituting the given values;
N(L) = 200 × 10%/100%
N(L) = 200 × 0.1
N(L) = 20
The expected number of left handed people is 20.
The first step to determine the function is to find the total cost of the auction. This is done by adding all the prizes and the cost of the food.

The total cost of the auction is $900. Since the cost of 50 tickets should be able to cover the cost, we need to divide the total cost by the number of tickets to determine the cost of each ticket.

Each ticket must be sold as $18. The whole function is:
