Step-by-step explanation:

Mean is adding all the numbers together then *divide by the number of numbers you added:

4 + 4 + 6 + 7 + 9 + 9 + 9 + 10 + 14 + 17 + 21 = 110

110 / 11 = 10

Median is the middle number: 9

The number that appears the most often is the mode: 9

The range is the difference between the lowest and highest number:

21 - 4 = 17

Answers

Answer:

y= -2x + 7

Step-by-step explanation:

first, we know the slope will be negative because the like is going down

lets look at the point that is on the y-axis, this will be our y-intercept

7 is the point hitting the y axis, plug this into the equation

so far we have y=7

now let's find the slope, starting at 7, we go down 2 and over one to get to the next point. let's add this

y= -2x+7

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

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 .
