Answer:
$51, 200
Step-by-step explanation:
First is to find the increase of tuition
$3,200 × .8 = $2560
then subtract the year.
2020-2000=20
lastly multiply the year and the increase of tuition to know the final answer
$2560 × 20 = $51,200
Answer:
9
Step-by-step explanation:
We're using the Pythagorean theorem here since it's a right triangle.
a^2 (side) + b^2 (side) = c^2 (hypotenuse)
12 = a
x = b
15 = c
12^2 + b^2 = 15^2
144 + b^2 = 225
- 144 - 144 (subtracting 144 from both sides to isolate b)
b^2 = 81
(getting rid of the exponent by squaring both sides)
b = 9
x = 9
P(z ≤ -a) + P(-a ≤ z ≤ a) + P(z ≥ a) = 1 - P(z ≤ a) + [P(z ≤ a) - P(z ≤ -a)] + 1 - P(z ≤ a) = 2 - 2P(z ≤ a) + P(z ≤ a) - [1 - P(z ≤ a)] = 2 - P(z ≤ a) - 1 + P(z ≤ a) = 1
Therefore, option D is the correct answer.
Answer:
Coordinate grid shown from negative 2 to positive 2 on the x-axis and negative 2 to positive 2 on the y-axis in increments of 1 over 4. Only the whole numbers are labeled. A point A is shown at the intersection of one grid line to the right of the y-axis and 7 grid lines below the x-axis.
Step-by-step explanation:
0.25 = 1 over 4
-1.75 = -7 over 4
When grid spacing is 1 over 4, the x-coordinate is 1 grid line to the right of the y-axis, and the y-coordinate is 7 grid lines down from the x-axis.
