Answer:

1. 7/41

2. 7/15

Step-by-step explanation:

1. Probability that it is a multiple of 6 given that it is a 2 digit number: There are 7 numbers that are a multiple of 6 and are 2 digits: 12, 18, 24, 30, 36, 42, and 48. There are 41 numbers that are 2 digits. So, it is 7/41

2. Probability that it is at least 20 given that it is prime. Out of the prime numbers from 1-50, 7 of them are at least 20 and there are 15 primes in that range in total. So, it is 7/15

Solve ( x + 1 < 5) ∩ ( x - 4 > -3).

The intersection of (x+1-3) is (1,4)

Explanation:

The expression is (x+1-3)

To determine the intersection of these two inequalities, let us solve the two inequalities separately.

Consider x+1

Subtracting both sides by 1, we have,

x

Also, consider x-4>-3

Adding both sides by 4, we have,

x>1

Using these two simplified inequalities in the expression, we have,

(x1)

Writing this in the interval notation, we get,

(-\infty, 4) \cap(1, \infty)

Hence, the intersection of the two interval is

(1,4)

Thus, the intersection of (x+1-3) is (1,4)

Make a table showing all the possible outcomes for spinning the pointer of a spinner with four equal-sized sections labeled 1–4
natka813 [3]

Answer:

12.5%

Step-by-step explanation:

There are two types of spinners here and the outcome of them is independent. That means

P(odd number,C) = P(odd number) * P(C)

There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:

P(odd) = 2/(2+2)= 1/2= 50%

There are four letters and the desired outcome is C. The chance for C will be:

P(C)= 1/4= 25%

Then the chance will be:

P(odd number,C) = P(odd number) * P(C)

P(odd number,C) =50% * 25% = 12.5%

Step-by-step explanation:

2x+3x+45=180º because all of the angles of a triangle add up to 180

5x=180-45

5x=135

x=135/5

x=27
