H + 14 = 82
Subtract 14 from both sides.
h = 68 inches (height of the person)
Answer:
C. 3.4
Step-by-step explanation:
We need to find expected value, which is essentially the value that we expect to get based on the amount of each "thing" at hand.
Here, we have 4 multiple-choice questions worth 3 points each and 2 true/false questions worth 1 point each. Each multiple-choice question has 5 possible answers, so the probability that you get that multiple-choice question correct is 1/5. Similarly, each true/false question has 2 possible answers, so the probability that you get that question right is 1/2.
Expected value, denoted by E(x), has the formula:
E(x) = ∑ xp(x), where x is the number of points you get per problem here and p(x) is the probability of getting the problem correct
E(x) = 4 * 3 * (1/5) + 2 * 1 * (1/2) = 12/5 + 1 = 17/5 = 3.4.
The answer is thus C.

Answer:
x = 4
____________________________________________________
Explanation:
We're solving the equation: -8=-(x+4)
Solve:
-8=-(x+4)
Distribute the negative to the variables in the parenthesis.
-8 = -x - 4
Add 4 to both sides
-4 = -x
Divide by -1
4 = x (same as x = 4)

Answer:
80 square feet
Step-by-step explanation:
This time I will get it right for sure!
So first we need to find the area in feet, and then convert it in to inches.
1) Since the patio has the shape of a rectangle, then the formula is:
A = a * b
A = 20 * 16
A = 320 feet
2). Now we have to find the ratio, so:
320 / 4 = 80
So, the answer is
1 square inch to 80 square feet.
Hope this helps))
