Answer:
p(z<0.42) = 0.6628
Step-by-step explanation:
A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. That is to say:
μ = 0
σ² = 1
Using a calculator, we find that:
p(z<0.42) = 0.6628 (See picture attached)
Answer:x=-43
Step-by-step explanation:
To expand (x-11)(4x+1) to get x
x^2+x-44x-11
x^2-43x-11
So x=-43
Answer:
a) 42.8 degrees.
Step-by-step explanation:
sin-|(-0.27 +0.95) means the angle whose sine is (-0.27+0.95)
= sin-1(0.68)
Using a calculator the answer is 42.8 degrees.
Answer:
X=4 ; X minus two equals zero
Step-by-step explanation:
X minus two equals zero:
x-2=2
Add two to both sides:
x=4
