Answer:
P(25 < x < 37) = 0.77
Step-by-step explanation:
Given - If a Variable has a normal distribution with mean 30 and standard deviation 5
To find - find the probability that the variable will be between 25 and 37.
Proof -
Given that,
Mean, μ = 30
S.D, σ = 5
Now,
~ N(0,1)
Now,
P(25 < x < 37)
= 
= P(1 < z < 1.4)
= P(z < 1.4) - P(z < -1)
= 0.9192 - 0.1587
= 0.7605
≈ 0.77
∴ we get
P(25 < x < 37) = 0.77
Answer:
D. 8
Step-by-step explanation:
32^(3/5) is the same as ![\sqrt[5]{32}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B32%7D)
^3.
= 2 because 2^5=32
2^3 = 8
Answer:
C
Step-by-step explanation:
Answer:
? = 3
Step-by-step explanation:
given a line parallel to a side of the triangle and intersecting the other 2 sides, then it divides those sides proportionally , that is
= 
( cross- multiply )
4? = 12 ( divide both sides by 4 )
? = 3
