Answer:
36 m^2
Step-by-step explanation:
the formula for the area of a triangle is 1/2•b•h
so you’re going to do 1/2 times 12 times 6 to get the area of 36 m^2
Simple, use PEMDAS and then do your simple math and then your answer should be 86922.56604
Answer:
A number <u>X</u>
Step-by-step explanation:
Answer:
0.13093
Step-by-step explanation:
Give. That :
Population mean = 40% = 0.4
Sample size (n) = 64
Probability that more than 30 have computer at home
Mean = np = 64 * 0.4 = 25.6
Standard deviation = sqrt(n*p*(1-p)) = 3.919
P(x > 30)
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (30 - 25.6) / 3.919 = 1.1227353
p(Z < 1.122) = 0.13093 ( Z probability calculator)
