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! :)

20 fans at a 49ers game are asked what their favorite team is.
Answers
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.

What is multiplication?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.

Find the value of x:
Answers
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

NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!
Answers
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.

Write a function rule for "The output is two more than one-fourth of the input ."
Answers
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.
What is function?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.

1089 + x^2 = 4225
1089-1089 + x^2= 4225-1089 (subtract both sides)
x^2 = 3136
x = 56cm
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.
