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

Brainliest?

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!

In ABC, angle C is a right angle. Which statement must be true

Answers

Answer:

Step-by-step explanation:

a because the the sin is opposite divided by hypotenuse and the opposite of a is 12 and the hypotenuse is 13 so sin a would be 12/13

this is equals to the cosine of b because cos is adjacent/hypotenuse and the adjacent of b is 12 and the hypotenuse is 13 so cos b would be 12/13

what Is the answer to 1/6 + 2/3

Answers

Answer:

5/6

Step-by-step explanation:

When adding fractions, you must ensure the denominator is the same in both fractions.

In this case, the 3 can be multiplied by 2 to equal 6, the other denominator.

When multiplying fractions to create a common denominator, you must multiply the both the numerator and the denominator by the same value, to ensure that the fraction is still equivalent.

2/3 × 2/2 = (2×2)/(3×2) = 4/6

Replace 2/3 with its equivalent 4/6.

Now you will add the numerators together.

1/6 + 4/6 = (1+4)/6 = 5/6

Your final answer is 5/6

Answer:

5/6

Step-by-step explanation:

2/3--> 4/6 (GCF)

4/6+1/6=5/6

FE/sin38=18/sin90

FE=18sin38=11.08

DF/sin52=18/sin90

DF=18sin52=14.2

Answer:

FE = 11.08, DF = 14.18

Step-by-step explanation:

Use trigonometric ratios:

sin = opposite / hypotenusecos = adjacent / hypotenuse

Apply to the given triangle

Side FE

FE / DE = sin 38° (or cos 52°, the value is same)FE / 18 = sin 38°FE = 18 sin 38°FE = 11.08

Side DE

DF / DE = sin 52° (or cos 38°, the value is same)DF / 18 = sin 52°DF = 18 sin 52°DF = 14.18
