Answer:
<em>c. y = 1.25</em>
Step-by-step explanation:
The equation for direct variation is
y = kx,
where k is the constant of proportionality.
We can use the given values of x and y to find k for this case.
y = kx
-10 = k * 40
k = -10/40
k = -0.25
The equation for this case is
y = -0.25x
Now we let x = -5 and solve for y.
y = -0.25x
y = -0.25(-5)
y = 1.25
Answer: c. y = 1.25
X^2 = 360 - (92 + 95 + 92)
x^2 = 360 - 279
x^2 = 81
so
x = √81
x = 9
answer
x = 9

Answer:
1/24
Step-by-step explanation:
This is a mutually exclusive event.
There are four possible floors and four people.
The probability that the first floor is selected is 1/4
The same probability exists for the second floor and the third and the fourth.
So, the probability of all four people choosing different floors is 1/4 * 1/4 * 1/4 * 1/4 = 1/24
