Answer:
Step-by-step explanation:
Solution:
AM =( X_1 + X_2 )/2
=( 18 + 2 )/2
=20/2
=10
Find Geometric mean for data 18,2
Solution:
GM =sqrt( X_1 × X_2 )
=sqrt( 18 × 2 )
=sqrt(36)
=6
Answer:
Option C is correct.
Step-by-step explanation:
P(A or B) represents that event A has occurred or event B has occurred or both events A and B are happening.
We are given P(A or B) = 0.60 or 0.60/100 = 60%
So, Option C The probability that a customer buys either a taco or a drink is 60% is correct.
First, you find what 25% of $450.To do that, make 25% into a decimal, which is 0.25.Then you multiply 450 times 0.25 which is 112.5
Second, you find what 5% of 450. 5% as a decimal is 0.05. Then you multiply 450 times 0.05 which is 22.5
Third, you add 450+112.5+22.5 which is 585.
There you go. :) Hope that helped!
