Answer:
Okay I'll try to answer this from what you're trying to ask:) and good luck on your test!
Step-by-step explanation:
So to check that 4(n-2) is equal to 4n+8, you would do the distributive property. Now the distributive property is when you take the number outside of the parentheses (in this case 4) and multipy it by what is inside the parentheses (n and 2). With that, you'll get 4 times n which is 4n and 4 times 2 which is 8, combine them and voila! MAKE SURE YOU LOOK AT THE SIGN INSIDE OF THE PARENTHESES
4(n+2)
=4*n + 2*4
=4n+8
Here's another example
3(n-5)
=3*n - 3*5
=3n-15
Hope that helps:)

Please help me. It’s system of equations i really need the steps to it too. Please help me.
Step-by-step explanation:
The given equations are :
x-3y=-4 ....(1)
3x-9y=-12 ...(2)
Multiply equation (1) by 3.
3x-9y=-12 ....(3)
Subtract equation (2) from (3).
3x-9y-(3x-9y) = -12-(-12)
In these equations,
[tex]\dfrac{1}{3}=\dfrac{1}{3}=\dfrac{1}{3}[/tex]
It means the given system of equations have infinitely many solutions. The lines are coincident.

An arithmetic sequence is made up of __________.
A . expressions
B . coordinates
C . terms
D . variables
Answer:
An arithmetic sequence is made up of terms. In Mathematics, a term means each of the quantities in a ratio, series, or mathematical expression. For example, a series of numbers regarding an arithmetic sequence would be 9, 6, 3, 0, -3, -6, -9. Therefore, an arithmetic sequence is made up of terms.

(06.02)A six-sided number cube labeled 1 through 6 is rolled 600 times. An odd number is rolled 272 times. Compare the experimental probability of rolling an odd number with the relative frequency of rolling an odd number and select one of the statements below that best describes the situation.
The experimental probability and relative frequency are the same.
The experimental probability is larger than the relative frequency.
The experiment probability is smaller than the relative frequency.
There is not enough information to determine the relative frequency.
Answer: The experimental probability and relative frequency are the same.
Step-by-step explanation: In the question it ask you to compare the experimental probability of rolling an odd number with the relative frequency of rolling an odd number. If you compare these two things the outcome would be the same because these two terms are the same thing.
Look at the examples provided below:
"Example: you conduct an experiment where you flip a coin 100 times. ... So the experimental probability of getting tails in 100 trials is 53%, and 47 for getting heads in 100 trials."

During the party, Scoundrel offered her left paw 62.5% of the time.
62.5% • 100 = 0.625 • 100 = 62.5 times.
it wouldn't make sense to offer a paw 0.5 times, so round 62.5 to 63. After 100 trials, Jenna can expect that Scoundrel will offer the left paw 63 times.

If one of the 255 subjects is randomly selected, find the probability that the person is under 21 years of age. State answer as a simplified fraction.
under 21 years of age= 40 25 20 tot= 85
between 21 and 40= 35 20 30 tot = 85
over 40= 20 30 35 tot = 85
If one of the 255 subjects is randomly selected
P (over 40) = 85/255 = 1/3

Over the past 40 years, the percentage of homes in the United States with smoke detectors has risen steadily and has plateaued at about 95% (National Fire Protection Association website, January, 2015). With this increase in the use of home smoke detectors, what has happened to the dea rate from home fires? The DATAfile SmokeDetectors contains 17 years of data on the estimated percentage of homes with smoke detectors and the estimated home fire deaths per million of population. Click on the datafile logo to reference the data. DATA file
a. Do you expect a positive or negative relationship between smoke detector use and deaths from home fires? Why or why not? The input in the box below will not be graded, but may be reviewed and considered by your instructor_________.
b. Compute the correlation coefficient (to 4 decimals). If required enter negative value as negative number.
Is there a positive or negative correlation between smoke detector use and deaths from home fires?
Answer:
A. Negative correlation
B. Data isn't given
Step-by-step explanation:
A. A positive correlation occurs when variables that are related(not zero correlation)increase together, in other words variable a(independent variable) increases and makes variable b(dependent variable) increase too. There will be a negative correlation if the opposite happens, that is when variables that are related go in opposite directions, one increases while the other decreases. We observe from what we are told that a negative correlation occurs here since death rate from fires has likely(assumed) decreased as smoke detectors have increased.

9514 1404 393
Answer:
(3, 4)
Step-by-step explanation:
Put the numbers in the formula and do the arithmetic.
Q = (A + B + C)/3
Q = ((1, 1) +(4, 5) +(4, 6))/3 = (1+4+4, 1+5+6)/3 = (9, 12)/3
Q = (3, 4)
The centroid is (3, 4).

Identify the transformation from ABC to A'B'C.
A
B
a) (x+8, y+4)
b) (x-8, y-4)
d) (x-4. y-8)
C) (x+4, y+8)
Answer:
I think the answer is A, good luck have a great day! :D
The transformation from ABC to A'B'C is (x+8, y+4).
What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
We have,
Transformed Triangle ABC to A'B'C'.
Now, from the graph the coordinate of A from Triangle ABC is shifted 8 units to the right.
and, moves 4 units upside.
Thus, the transformation applied here is (x+8, y+4).

According to a recent survey of 1700 people, 63% feel that the president is doing an acceptable job. We are interested in the population proportion of people who feel the president is doing an acceptable job. NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)
Required:
Which distribution should you use for this problem?
Answer:
The standard normal distribution should be used due to the large sample size ; also also proportions are what is required.
Step-by-step explanation:
Given that:
Sample size, n = 1700
p = 63% = 0.63
Given that the sample size is large at n = 1700 ; the binomial distribution and t - distribution aren't ideal for distributions of such size. Also, we are interested in the population proportion which from the standard normal formula who's interval could be obtained thus :
[p ± Zα/2 * sqrt(p(1 - p))]
Both the t-distributon and binomial distributions are for experiments whith relatively small or low.

and now for SUT
[tex]\angle SUT = 3(11)+6= 33+6 = 39[/tex]
angle RUT=90° ( angle of rectangle)
angle SUT+angle RUS=angle RUT

angle SUT =39°
