1. The probability that we select a red marble is 1/3.

We found this out by taking the amount of red marbles there are and the total amount of marbles. The total amount of marbles is 18 and there are red marbles. So, it would become 6 out of 18 or 6/18. Then, we simplify 6/18 to the simplest form. The greatest common factor of both of those numbers is 6. Lastly, we divide each of them by 6 to get the simplest form.

6/18 = (6/6)/(18/6)

(6/6)/(18/6) = 1/3

So, therefore, the theoretical probability of picking a red marble is 1/3.

2. The probability that we select a blue marble is 2/3.

We can find this out by taking the amount of blue marbles there are and the total amount of marbles. We know that the total amount of marble is 18 and there are 12 blue marbles. So, we simply get the GCF (greatest common factor) and divide them by it.

Greatest Common Factor of 12 and 18 = 6

12/18 = (12/6)/(18/6)

(12/6)/(18/6) = 2/3

Thus, the theoretical probability of picking a blue marble is 2/3.

An angle measures 14.8° less than the measure of its complementary angle. What is the measure of each angle?
Gre4nikov [31]

Answer:

The larger angle is 52. 4

The smaller angle is 37. 6

Step-by-step explanation:

The equation is:

(x-14. 8)+x=90

x+x-14. 8=90

2x=90+14. 8

2x=104. 8

x=52. 4

The value for the larger angle is x

and x =52. 4

The value for the smaller angle is x-14. 8

and x-14. 8=52.4-14.8

=37.6

Verification

(x-14.8)+ x=90

(52.4-14.8)+52.4=90

37.6+52.4=90

90=90
