Answer:
1/4
Step-by-step explanation:
y=1/4x-4
This equation is in the form
y = mx+b where m is the slope and b is the y intercept
The slope is 1/4 and the y intercept is -4
Step-by-step explanation:
x^2/9 z^2
hiiii checkout the steps
35 squared or 35^2 is equal to 35x35
which equals 1225 Hope this helped!

Answer:
The largest average score the researcher should consider is 117
Step-by-step explanation:
Mean = xbar = 114
Standard deviation = σ = √(variance) = √(400) = 20
Let The standardized score that corresponds with lower 56% be x'.
Let the z value that corresponds to the probability of 0.56 be z'
We need to obtain the z value that corresponds with a Probability of P(z ≤ z') = 0.56
using the normal probability distribution table,
z' = 0.151
P(z ≤ z') = P(z ≤ 0.151) = 0.56
z' = (x' - xbar)/σ
0.151 = (x' - 114)/20
x' = 117
