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

a=1/2pa, solve for p
NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!
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.

Find the missing side length of the right triangle
using the Pythagorean Theorem or PT converse.
A) 32 cm
B) 21 cm
C) 73 cm
D) 56 cm
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.

Rewrite this equation in slope-intercept form.
6x-3y=12
Answer:
y = 2x - 4
Step-by-step explanation:
slope intercept form: y = ax + b
6x - 3y = 12
⇔ 6x - 12 = 3y
⇔ y = 2x - 4
Solve for x.

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.
0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.
Answer: 1.08j
Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right
1.08j
I’m not 100% sure tho
The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.
Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket
= j + 0.08j
= 1.08j
Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

Find the value of x:
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
