B 10/12 = 6/7.2 = 8/9.6 = 5/6

Answer:

The anwser is C: 6/5

Step-by-step explanation:

12 divided by 10 = 1.2 = 6/5

9.6 divided by 8 = 1.2 = 6/5

7.2 divided by 6 = 1.2 = 6/5

Answer:

1. mean:10 median:11 mode:13

2. mean:30 median:35 mode: 20

Answer:

1. Mean: 10 Median: 11 Mode: 13

2. Mean: 26.7 Median: 20.5 Mode: 20

Step-by-step explanation:

1. Mean: 6+7+11+13+13 = 50 then, 50/5 = 10

Median: 6, 7, 11, 13, 13 in the middle: 11

6- crossed

13- crossed

7- crossed

13- crossed

That leaves 11!

Mode: 13 appears two times. All the other numbers only appear once.

2. Mean: 0+20+20+30+40+70 = 160 then, 160/6 = 26.7 ( rounded to nearest tenth)

Median: 0, 20, 20, 30, 40, 70

0- crossed

70- crossed

20- crossed

40- crossed

20- crossed

30- crossed

They all are crossed, but the last 2 to be crossed are 20 and 30. The middle of those two numbers is 20.5 therefore, the median is 20.5!

Mode: 20 appears twice while the rest only appears once.

I hope this helps, good luck! :)

Answer:

4) Unbiased; 5) Biased

Step-by-step explanation:

4) states that the audience of the poll was "random" people meaning it's a good foundation of data as they weren't chosen for the employee noticing their specific affiliation with being overjoyed with the product (as the question doesn't say) or for not liking (have complaints about it) the product.

5) The audience of the poll is fans of a sports team--definitely biased because they'll say they love the 49ers being a fan for them. Leads to skewed results not representing a portion of a population accurately.

Answer:

8) 4 hr 10 minutes

9) 12:43

Step-by-step explanation:

#8 is assuming the 10 minutes she stopped is part of the time

#9 is assuming she arrived right at 1:30

Answer:

8) 4 hr 10 minutes

9) 12:43

Step-by-step explanation:

Answer:

A = (1/2)Pa = Pa/2

You can multiply both sides by 2 to eliminate the fraction on the right side:

2A = 2(Pa/2) = Pa

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

Rewriting:

P = 2A/a

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

Answer:

x = 3

Step-by-step explanation:

These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:

(10x + 1) = (12x - 5)

Add 5 on both sides:

10x + 6 = 12x

Subtract 10x on both sides:

6 = 2x

Divide 2 on both sides:

3 = x

Answer:

(10x+1)°=(12x-5)°. [vertically opposite angle]

1+5=12x-10x

6= 2x

3=x

therefore,x=3

Larry won the award because of 40 popular songs, but do not confuse this with the total songs that larry wrote.

Larry actually wrote 40+32 = 72 songs

Out of these 72 songs, 40 were popular and thus Larry got the award.

Answer:

y=(x/4)+2

Step-by-step explanation:

let y be the output and x be the input. So,

y=(x/4)+2

The function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.

A function is a relation between a dependent and independent variable. We can write the example of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to find the function rule for "The output is two more than one-fourth of the input."

The given mathematical statement is - "The output is two more than one-fourth of the input."

Assume the input to be {x} and the output be {y}. So, we can write that -

(output) = (two) + (1/4)(input)

y = 2 + (1/4)x

Therefore, the function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.

Answer:

yes, it will fit.

Step-by-step explanation:

10 x 6 = 60ft

she has an area of 108ft

yes, it will fit because 60ft is smaller than 108ft.

a = 251.33 (circumference of triangle)

b = 40 degrees (isosceles triangle)

c = 40 degrees (isosceles triangle)

d = 100 degrees (40+40=80, 180-80=100)

It takes the Pluto about 14.375 x 10¹⁰ years to orbit the Sun while the Sun completes one orbit around the Milky Way

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

It takes the Sun about 2.3x10⁸ years to orbit the center of the Milky Way.

It takes Pluto about 2.5 times 10 squared years to orbit the Sun.

Pluto orbits the Sun while the Sun completes one orbit around the Milky Way,

= 2.3 x 10⁸ x (2.5 x 10)²

= 14.375 x 10¹⁰

Therefore, the required time is 14.375 x 10¹⁰ years.

Answer:

The answer is D) 56 cm

Step-by-step explanation:

Using the Pythagorean Theorem, you would first have to multiply 65 x 65 to get 4225 and multiply 33 x 33 to get 1089. Then, for the last step, you will have to solve this little equation: 4225= 1089 +? To do this, you will have to subtract 4225 - 1089 = 3136. Finding the square root, you will finally get your answer of 56 cm.
