Answer:
81
Step-by-step explanation:
Given data:
mean μ = 70.
standard deviation σ, 9.6.
P(Z < 1.123) = 0.13
z = 1.13
Use the z-score formula,
x = z×σ +μ
Substitute the values in the above equation.
x = 1.13 9.6 + 70 = 81
The minimum score required for an A grade is = 81
The perpendicular line through (2, 1) is
.. y = (x -2)+1
or
.. y = x -1
The rock hits the gorund at 45s. is the answer
The function is written in slope intercept form where y=mx+b and m is the slope.
g(x)=10x+4
The m value is 10, and therefore the slope is 10.
Final answer: 10
