The coefficient of the variable y for the given equation 4 - 2y is -2.
What is the coefficient?A coefficient is a number that is being multiplied by the variable, i.e. the numerical term with variable, that is a number that is placed before another variable. While the variable represents some quantity, it may also represent a number, a function, etc. The letters a, b, c, x, y, and z are common symbols used for variables.
We have,
An equation 4 - 2y,
So,
In the above-given expression,
We have only one variable and one Constant term,
i.e.
Constant term = 4
And,
Variable term = -2y
So,
In the variable term,
The coefficient of y = -2
So,
The coefficient of y is -2.
Hence, we can say that the coefficient of the variable y in the given equation is -2.

Answer: b
Step-by-step explanation:
Cuz is a negative get in absolute value it always comes out positive
And it says below 0-9=-9
Answer:
BStep-by-step explanation:
__________________________________________________________
B is the answer because,
if the negative sign is not inside the "brackets," then the number will still be negative.
__________________________________________________________
But, if the negative sign is connected to the number, or inside the "brackets," then it will always be positive.
__________________________________________________________
Here are the reasons why the rest are wrong.
__________________________________________________________
A is not correct because the outcome isn't negative, even though it's correct in mathematical instances.
__________________________________________________________
C is not correct because it is plainly not correct in itself.
__________________________________________________________
D is also not correct because it is not correct in the mathematical equations, even though it has a -9 as the equal, it's still wrong.

Rewrite the expression as a product using the GCF and distributive property. 27 + 45
Step-by-step explanation:
GCF of 27 and 45 is 9
Answer: 9 (3+5)
Step-by-step explanation:
The GFCF of these two numbers is 9 as they can both be divided by it
Distributive property form is when you place the GFC outside parenthesis so that the equation can be multiplied in order to show the original equation and dividing the numbers by the GCF so that it does not give you a larger number than what you started with
27/9=3 + 45/9=5
So, keeping this in mind the distributive property form would be 9(3+5)
Answer 9(3+5)

Answer:
its B on e2020
Step-by-step explanation:
14%
If the Algerian government wishes to raise $9 billion in tax revenue, income tax rate should be 14%.
What should the income tax rate be?
Income tax is a form of tax levied on the income of labor by the government. Income tax reduces the income earned by labor.
In order to determine the income tax rate, take the following steps:
Determine the total income of the workforce: 9,416,534 x $6,844 = 64.45 billion
Now, divide the desired tax revenue by the total income: (9 billion / 64.45 billion) x 100 = 14%

Online photos: A poll surveyed 1765 internet users and found that 865 of them had posted a photo or video online. Can you conclude that less than half of internet users have posted photos or videos online? Use the α 0.01 level of significance and the P-value method with the TI-84 calculator.
1. State the appropriate null and alternate hypotheses.
2. Compute the P-value.
Answer:
H0 : p = 0.5
H1 : p < 0.5
P value = 0.200454
Step-by-step explanation:
Given that :
Claim : Less than half internet users have posted photos or videos online.
Sample Proportion (p) = 865 / 1765 = 0.4900
The null hypothesis : H0 : p = 0.5 (that is half of internet users have posted photos online.
The alternative hypothesis : H1 : p < 0.5 (that is less than half of internet users have posted photo or video ;
P = 0.5
q = 1 - 0.5 = 0.5
The test statistic :
Z = p - p0 / sqrt(p0 * (q/n))
Z = (0.49 - 0.5) / sqrt(0.5 * (0.5/1765))
Z = - 0.01 / sqrt(0.5 *0.0002832)
Z = - 0.01 / sqrt(0.0001416)
Z = - 0.01 / 0.0119013
Z = - 0.8402443
The corresponding p value from the z statistic score at α = 0.01
= 0.200454

Betty tabulated the miles-per-gallon values for her car as 26.5, 28, 30.2, 29.6, 32.3, and 24.7. The sample standard deviation is 2.728. The driver’s manual for Betty’s car lists the mpg for her car as 25. t equals fraction numerator x with bar on top minus mu over denominator begin display style beveled fraction numerator s over denominator square root of n end fraction end style end fraction The t test statistic for a two-sided test would be __________.
Answer:
3.188
Step-by-step explanation:
Given that :
Sample data: 26.5, 28, 30.2, 29.6, 32.3, 24.7
Sample standard deviation (s) = 2.728
Mean (mu) = 25
Tstatistic formula :
(x - mu) / (s/sqrt(n))
n = sample size = 6 ; s = 2.728 ; mu = 25
Sample mean (x) = (26.5 + 28 + 30.2 + 29.6 + 32.3 + 24.7) / 6
Sample mean (x) = 171.3 / 6 = 28.55
Tstatistic = (28.55 - 25) / (2.728 / sqrt(6))
Tstatistic = 3.55 / 1.1137013
Tstatistic = 3.1875692
