Answer:
P [ K > 3.95] = 0.5633
Step-by-step explanation:
The interpretation of the given question goes thus;
Suppose that K is a random variable
P[-3.95 ≤ K ≤ 3.95] = 0.725
where; P [ + 3.95 < K ] = P [K < - 3.95]
P[K< 3.95] - P [K > - 3.95] =0.725
P [K < 3.95] - [ 1- P[K < 3.95]] = 0.725
P[k < 3.95] - 1 + P [ K < 3.95] = 0.725
3.95 P [ K < 3.95] -1 = 0.725
3.95 P [ K < 3.95] = 1.725
P [ K < 3.95] = 1.725/3.95
P [ K < 3.95] = 0.4367
P [ K > 3.95] = 1 - P[K< 3.95]
P [ K > 3.95] = 1 - 0.4367
P [ K > 3.95] = 0.5633
Answer:
15:27
Step-by-step explanation:
27 kids in the class and 15 boys
Answer
f(6) = -33 and g(-3) = -52
Explanation;
Given the function
f(x)=-5x-3
f(6)=-5(6)-3
f(6) = -30 -3
f(6) = -33
Similarly if g(x)=2x^3+2
g(-3)=2(-3)^3+2
g(-3) = 2(-27)+ 2
g(-3) = -54 + 2
g(-3) = -52
Hence f(6) = -33 and g(-3) = -52
