A) 90-55=35 since a right angle is 90 total\
b)ii
Answer: The probability that the sum is 11 given that the first cube shows a 6.
Step-by-step explanation:
By the definition of conditional probability,
If we have two probabilities A and B where A and B are dependent variable,
If we have to find the probability of occurring the event A when B is given ,
Then we find P(A/B).
Here A is the event that there is 6 in first die when we rolled two dice,
And, B is the event that the sum of the numbers shown in both die is 11,
Hence, P(A/B) shows, The probability that the sum is 11 given that the first cube shows a 6.
Answer:
12 inches
Step-by-step explanation:
Just do 6 x 2.
6 x 2 = 12
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b".
For a. I got x=7.
