23.8
29.9
Find the mean temperature.

Answers

Answer:

29.9 °F

Step-by-step explanation:

The formular for mean is given as;

Mean = Sum of Terms / Number of terms

Number of terms = 6

Sum of terms = 35.5 + 30.8 + 27.3 + 32.1 + 23.8 + 29.9 = 179.4

Mean = 179.4 / 6 = 29.9

Step-by-step explanation:

Step 1: Define Systems

y = 3

y = -3x + 6

Step 2: Solve for x

Substitute in y: 3 = -3x + 6[Subtraction Property of Equality] Subtract 6 on both sides: -3 = -3x[Division Property of Equality] Divide -3 on both sides: 1 = xRewrite/Rearrange: x = 1

Step 3: Solve for y

Answer:

Mean: 20

Median: 20

Mode: 5, and 20

Range: 30

Step-by-step explanation:

Mean: Add all the numbers up then divide by the total of numbers there are. 5+30+35+20+5+25+20=140 divided by 7

Median: middle number, list all the numbers from greatest to least and whatever number is in the middle is your answer (5, 5, 20, 20, 25, 30, 35)

Mode: Number that is repeated the most. 5, and 20

Range: The distance from the highest number to the lowest 35-5= 30

I’m going to do #1 and explain how I do it and I hope it will help!

#1 -

5, 30, 35, 20, 5, 25, 20

Rearrange in order.

5, 5, 20, 20, 25, 30, 35

Mean: Add all the numbers in the set together, then divide by how many numbers there are. So in this case, when you add these up, you get 140. Then you have to divide it by how many numbers, which there are 7 numbers in the set. So... 140 divided by 7 is 20. The mean is 20.

Median: The median is always the middle number in the set. If there are even numbers, you subtract the two numbers in the middle to get a median. But in this case, there is odd, and the middle number there is 20.

Mode: How you find the mode is simply the number that repeats the most or that you see the most. If no number repeats in the set, then you put “No Mode.” So here, there are two numbers that appear twice, so 5 and 20 is the mode.

Range: The range is subtracting the first from the last number. In this case, it would be 35 - 5, and that would be 30, so the range is 30!

The larger angle <K, has a measure of 120 degrees.

Step-by-step explanation:

So, a supplementary angle are two or more angles that combine to form a 180 degree straight line. So here, we need to set up an algebra equation.

2x = the larger angle (because it's two times the smaller angle)

x = the smaller angle

So then, you need to set both equal to 180 degrees, since combine they equal 180 degrees

2x + x = 180

3x = 180

x = 60

Using basic algebra, we see that the smaller angle is 60 degrees, but wee need to find the larger angle. Remember, we represented the larger angle as 2x.

2 time 60 is 120, so the larger angle is 120 degrees

Hope that helps :)
