The area of right triangle=1/2*leg1*leg2=20 cm2
Answer:
The Slope is calculated Using the formula

The line passed through (5, 7) and (8, 8):
The slope is

The slope equals

Point D is located between 35 and 40 so the possible answers are 36, 37, 38, and 39.
Point D is closer to 40 than 35, so we narrow down the option to 38 or 39.
39 would have been really close to 40, so Lara's statement is reasonable to say 38 is point D.
It’s B ) THE SLOPE IS POSITIVE
Answer:
93% probability of a student taking a calculus class or a statistics class
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a student takes a calculus class.
B is the probability that a student takes a statistics class.
We have that:

In which a is the probability that a student takes calculus but not statistics and
is the probability that a student takes both these classes.
By the same logic, we have that:

The probability of taking a calculus class and a statistics class is 0.07
This means that 
The probability of taking a statistics class is 0.90
This means that
. So



The probability of a student taking a calculus class is 0.10
This means that 



What is the probability of a student taking a calculus class or a statistics class

93% probability of a student taking a calculus class or a statistics class
