If the probability of a student taking a calculus class is 0.10, the probability of taking a statistics class is 0.90, and the p

Stells [14]

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:

$A = a + (A \cap B)$

In which a is the probability that a student takes calculus but not statistics and $A \cap B$ is the probability that a student takes both these classes.

By the same logic, we have that:

$B = b + (A \cap B)$

The probability of taking a calculus class and a statistics class is 0.07

This means that $A \cap B = 0.07$

The probability of taking a statistics class is 0.90

This means that $B = 0.9$ . So

$B = b + (A \cap B)$

$0.9 = b + 0.07$

$b = 0.83$

The probability of a student taking a calculus class is 0.10

This means that $A = 0.1$

$A = a + (A \cap B)$

$0.1 = a + 0.07$

$a = 0.03$

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

$A \cup B = a + b + A \cap B = 0.03 + 0.83 + 0.07 = 0.93$

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

One angle of a triangle measures 36.5 degrees. What is the measure of the smaller angle?

Sunny_sXe [5.5K]

The final answer would depend in the type of triangle we are analyzing, however here are the possible outcomes:

1.) If it was a right triangle, 36.5 would be the smaller angle.

2.) It cannot be an equilateral triangle since all angles would be 60°.

3.) In a isosceles triangle, 36.5° would be the smaller, since the others would be 72°.

4.) In an scalene triangle it cannot be determined unless we had 2 angles since in that kind of triangle all angles can be different.

5.) In an acute triangle, 36.5° would be the smaller angle.

6.) In an obtuse triangle it cannot be determined unless we had 2 angles, since it can have highly acute angles.

Find the value of y- ( 8y +2) and (3y +5)= 73

kiruha [24]

Y=6 because if you break it down you get (11y+7) =73 then you subtract 7 from both sides to get 11y=66 then you divide 11 on both sides to get y=6
