Find A ∩ B if A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7}. {5} {1, 2, 3, 5, 7, 8, 11, 14}
Lana71 [14]
Answer:
A ∩ B = {5}
Step-by-step explanation:
We are trying to find the intersection (what they both have in common)
A = {2, 5, 8, 11, 14}
B = {1, 3, 5, 7}
The only thing they both have in common is 5
A ∩ B = {5}
Answer:
It is a Binomial experiment with n = 8 and p = 0.25
Step-by-step explanation:
It is given that we draw 8 cards out of the well shuffled deck of 52 cards one by one replacement.
Given :
P (getting a spade) =
= 0.25
As in the question, we are sampling with the replacement, so the probability of getting a spade in each draw remains the same and the all the draws are independent.
Therefore it is a Binomial experiment with n = 8 and P = 0.25
Answer:
2
Step-by-step explanation:
You count terms that are seperated by - and + signs. Any type of fraction is considered one term.
So you count 8y as one term and the rest is a whole fraction so you also count that as one term.
You add all the terms together and you have 2 terms in this equation.
Hope this helped :)
Answer:
Multiply 2/3 and your number. If you have a whole number, convert it to a fraction by putting it over a denominator of 1. When multiplying fractions, calculate numerator times numerator, then denominator times denominator. For example, to find two-thirds of 18, multiply 2/3 x 18/1 to get 36/3.
Answer:
28571/1000
Step-by-step explanation:
r/5 4/7
Cross Multiply to get
r7 and 20
divide both sides by 7
r = 2.8571
Since that is in the thousands place the answer is 28571/1000
