We can find the length of this side with
AB² = BC² + AC²
where AB is the length, BC is the width and AC is the height
AB² = 10² + 8²
AB² = 100 + 64
AB² = 164
AB = √164
AB = 12.81
or
AB = 12.8
Answer:
0.04845
Step-by-step explanation:
Probability that less than 7 but more than 4 bulbs from the sample are defective :
P(4 < X < 7) = P(x = 5) + P(x = 6)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
From the question :
p = 0.2 ; 1 - p = 0.8 ; n = 11
P(x =5) = 11C5 * 0.2^5 * 0.8^6 = 0.03876
P(x = 6) = 11C6 * 0.2^6 * 0.8^5 = 0.00969
P(4 < X < 7) = P(x = 5) + P(x = 6)
P(4 < X < 7) = 0.03876 + 0.00969
P(4 < X < 7) = 0.04845

Answer:
20 tables
Step-by-step explanation:
you can set up an equation where P/10=tables where P=number of people. so since you have 200 people coming, so you divide 200 by 10 and you will have 20 tables

Answer:
9m*9m*9m*9m
Step-by-step explanation:
That's all an exponent does It multiplies and because it's on the outside of the parentheses it multiplies both of them
