your correct answer should be: z = (x - mean) / SD = (79 - 70) / 3 = 3
P (Z > 3)? = 1 - F (z) = 1 - F (3) = 0.00135 i hope this is helpful! :D
Answer:
-14.2
Step-by-step explanation:
f(x)=-3x+5 Write original equation
f(6.4)=-3(6.4)+5 Substitute 6.4 in for x.
=-14.2 Solve
2/3
1/8
Would be the simplest forms
The truth is they will intersect and let me explain it to you:
f(x) = x^2 + 6x +10
13 = x^2 + 6x+ 10
x^2 + 6x - 3 = 0
Solving the quadratic equations:
The roots of the equation is
x = 0.4641 and
x = -6.4541
That is why we say that It will intersect
