Answer:
The probability that a student is taking calculus given that he or she is taking statistics is = 0.26
Step-by-step explanation:
the probability that a student is taking calculus given that he or she is taking statistics.
Let C = Calculus
S = Statistics
We solve this above Question nursing the formula;
P ( C ∪ S) = P(C) + P ( S ) - P ( C ∩ S)
From the question,
P(C) = 0.10
P( S ) = 0.18
P ( C ∩ S) = 0.02
P ( C ∪ S) = ???
P ( C ∪ S) = 0.10 + 0.18 - 0.02
= 0.28 - 0.02
= 0.26
Answer: 2.5%
Step-by-step explanation:
Mean score = 65
Standard deviation = 5
Score (x) = >75
Z-score = [(score - mean) ÷ standard deviation]
Z - score = [(75 - 65) ÷ 5]
Z - score = 10 ÷ 5 = 2
P(score higher than 75) = 100 - 95 = 5/2 = 2.5%
Answer:
1
Step-by-step explanation:
None of the sides are equal. Isosceles means that 2 sides are equal. Equilateral means that all sides are equal.
Answer:
256
Step-by-step explanation:
since the the path surounds both sides of the garden you have to add 2 x instead of just x
let me show you what i mean. 10=garden width and 3=path width=x
since it is a square, we can calculate the area by taking one side and squaring it so you get (10+2x)^2 which is 16^2 since x is 3, the width of the garden
to do simaler problems just use thei formula (garden length+2path length)^2 or (garden length+2path length)times(garden length+2path length)
