The <u>correct answer</u> is:
<span>Relative frequencies are the probabilities occurring in sampling distributions.
Explanation:
Relative frequencies are the fraction of times an event occurs within a sample.
This is the same definition as experimental probability; thus relative frequencies are the probabilities occurring in sampling distributions.</span>
7x+ 8y= 22
6x+ 5y=17
^Is this the format of the equation you are trying to solve?
Answer:
Step-by-step explanation:
The expression is
x^2 - 4
This is a quadratic expression.
To find the solution, we will equate the the expression to zero. It becomes
x^2 - 4 = 0
Add 4 to the left hand side of the equation and the right hand side of the equation. It becomes.
x^2 - 4 + 4 = 0 + 4
x^2 = 4
Take square root of the right hand side of the equation and left hand side of the equation. It becomes
√x^2 = √4
x = ± 2
x = 2 or x = - 2
He spends 30 to enter and 4 per ride
y = 4x + 30....with x being the number of rides and y being the total cost
Answer:
Correct. He transformed the triangle according to the rule (x, y) → (–y, x)
Step-by-step explanation:
<u>Given</u>
F(3, 2), H(4, 5), G 1, 2)
F'(-2, 3), H'(-5, 4), G'(-2, 1)
<u>Find</u>
Whether the triangle was correctly transformed using the rule ...
(x, y) → (–y, x).
<u>Solution</u>
For point F, we have ...
x = 3
y = 2
Then the rule tells us the point F' should be ...
F' = (-y, x) = (-2, 3)
This is the point Quinton found for F', so his transformation was correct. (We can similarly verify that H' and G' are also correct.)
