Given that is a standard normal random variable, compute the following probabilities. round your answers to 4 decimal places. a. p(0 ≤ z ≤ 0.70) b. p(-1.57 ≤ z ≤ 0) c. p (z > 0.39) d. p(z ≥ -0.33) e. p(z< 2.10) f. p (z≤ -0.63)

a)0 .7580     b) 0.4406     c) 0.6554      d) 0.3745     e) 0.9817     f)0.2611

Step-by-step explanation:

All values where obtain from  normal distribution table for Z

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
