Describe the probability of rolling a die and landing an even number while tossing a coin and landing on heads.

A. as likely to happen as not to happen

B. impossible

C. likely

D. unlikely

Answers

Answer:

Step-by-step explanation:

The first step is to find the possibility of the die landing on an even number which is 3/6 as there are 6 possible turn outs and 3 of them are even. Which means the probability is 3/6 or in its simplified version 1/2. The second step is to find the probability of landing on heads which is 1/2 as there are 2 possible turn outs and 1 of them is heads. Which means the probability is 1/2 (it cannot be simplified) . To find the probability of both we need to times them together so 1/2×1/2= 1/4. So the probability of getting both is 1/4 which is unlikely probability so the answer is D .

Answer:

The measure of angle a is 45 degrees.

Step-by-step explanation:

Notice that since PS = RS, this is an isosceles triangle. This means that the base angles are equal. We also know that the sum of interior triangles of a triangle equals 180, then, if 'a' is the base angle, we have the following equation:

90 + a + a = 180

2a = 180 - 90 = 90

a = 90/2 = 45

a = 45

Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle.

There are 5 candy canes for every 9 presents. How many candy canes are there if there are 108 presents? (PLEASE SHOW YOUR WORK TOO! its for a grade:( )

Answers

Answer:

60 candy canes

Step-by-step explanation:

To find how many candy canes we have to remember that there are 5 candy canes for every 9 presents.

108 is divisible by 9 so we do the equation:

108 ÷ 9 = 12

Now we multiply 12 by 5 since theres 5 candy canes per 9 presents

12 × 5 = 60

To check our work we can divide-

9 ÷ 5 = 1.8

108 ÷ 60 = 1.8
