Answer: X=4 and y=4
Step-by-step explanation:
Answer:
x =4
Explanation: As x and y are inversely proportional, the equation can be represented as x=k/y.
Substituting x=2 and y=12, we get 2=k/12=> k=12⋅2 => k=24.Equation can be represented as x=24/y. So, when y=6, we get x=24/6 => x=4
YT radio play songs at random every day from the hundreds of songs it contains in memory data. Any song can be played at any time, even if it is repeated. There are 500 pop songs, 330 Country songs, 265 rock songs, and 405 R&B songs. If the station just played two pop songs in a row, what is the probability that the next song will also be a pop song?

What are the solutions of the compound inequality?
Graph the solutions.
2x-2<-12 or 2x+3>7
Answer:
x < -5 or x > 2 , and because or can be in either, doesn't and literally can't be in both
Step-by-step explanation:
When you simplify 2x-2>12, it's like an algebra problem where you just add 2 to both sides and then divide by 2. Same for 2x+3>7, except you subtract 3 and then divide by 2
Select Parameter or Statistic to classify each statement.
1.) 85% of those surveyed were in favor of bike lanes.
Parameter or Statistic
2.) Each member of the soccer team has an average of 2 jerseys.
Parameter or Statistic
3.) Of the 100 swim teams surveyed across America, 23 practice 10 hours a week.
Parameter or Statistic
4.) The golf team's average score is 79.
Parameter or Statistic
Answer:
1) Statistic
2) Parameter
3) Statistic
4) Parameter.
Step-by-step explanation:
Parameter: is a number that describes the whole population.
Statistic: is a number that describes a sample.
The difference is:
50% of the cats are nice (parameter, because talks about all the cats)
out of 100 cats surveyed, 39 are nice (statistic, because talks about a sample of 100 cats)
Then:
1) 85% of those surveyed were in favor of bike lanes.
This only refers to the surveyed people, so this only refers to a sample (and not the population that this sample represents) then this is a statistic statement.
2) Each member of the soccer team has an average of 2 jerseys.
In this case, we are talking about the whole population (the soccer team) then this is a parameter
3) Of the 100 swim teams surveyed across America, 23 practice 10 hours a week.
Here the information is about the sample (only 100 swim teams). So here the correct option is statistic.
4) The golf team's average score is 79
Here the information is about the average score for the entire golf team, so this information is about all the population in the golf team, then in this case the correct option is parameter.
Answer:
Statistic
Parameter

In a sequence described by a function, what does the notation f(3) = 1 mean?
ОА. .
The common difference of the sequence is 3.
OB.
The first term in the sequence has a value of 3.
O c.
The common ratio of the sequence is 3.
OD.
The third term in the sequence has a value of 1.
The number inside the parentheses is the input value, the number it equals is the output value.
F(3) means the 3 would be the third term in the sequence and that would equal 1.
The answer is:
D. The third term in the sequence has a value of 1.

3. The following dot plots compare the height of the members of the basketball team and the swimming team.
Determine the mean, median, and mode for each dot plot. Show your work!
Answer:
The mean for the first one is 65.83
the median is 65.5
the mode is 66
Step-by-step explanation:
to find the mean you add all your numbers together then divide by how many you have. So all the numbers added together then divided by 12.
The median is the middle number of your list. I would reccomend you to list out your numbers from least to greatest, then cross out the outer number until you get the middle number. in your case it is an even number so it is 65.5.
The mode, basically asking out of your numbers listed which has the most numbers. "sounds like most".

Find the length of side x in simplest radical form with a rational denominator.
Answer:
8
Step-by-step explanation:
sin Θ = opp / hyp
Θ = 60
opp = 4
hyp = x
sin 60 = 4 / x sin 60 = 0.5 or 1/2
1/2 = 4 / x
x/2 = 4
x = 8

Two separate tests are designed to measure a student's ability to solve problems. Several students are randomly selected to take both test and the results are give below Test A | 64 48 51 59 60 43 41 42 35 50 45 Test B | 91 68 80 92 91 67 65 67 56 78 71 (a) What is the value of the linear coefficient r (b) Assuming a 0.05 level of significance, what is the critical value
Answer:
a) r = 0.974
b) Critical value = 0.602
Step-by-step explanation:
Given - Two separate tests are designed to measure a student's ability to solve problems. Several students are randomly selected to take both test and the results are give below
Test A | 64 48 51 59 60 43 41 42 35 50 45
Test B | 91 68 80 92 91 67 65 67 56 78 71
To find - (a) What is the value of the linear coefficient r ?
(b) Assuming a 0.05 level of significance, what is the critical value ?
Proof -
A)
r = 0.974
B)
Critical Values for the Correlation Coefficient
n alpha = .05 alpha = .01
4 0.95 0.99
5 0.878 0.959
6 0.811 0.917
7 0.754 0.875
8 0.707 0.834
9 0.666 0.798
10 0.632 0.765
11 0.602 0.735
12 0.576 0.708
13 0.553 0.684
14 0.532 0.661
So,
Critical r = 0.602 for n = 11 and alpha = 0.05

Suppose that you are looking for a student at your college who lives within five miles ofyou. You know that 55 percent of the 25,000 students do live within five miles of you. Yourandomly contact students from the college until one says he or she lives within five miles ofyou. What is the probability that you need to contact four people
Answer:
The probability that I need to contact four people is 9.11%.
Step-by-step explanation:
Since I am looking for a student at my college who lives within five miles of me, and I know that 55 percent of the 25,000 students do live within five miles of me, and I randomly contact students from the college until one says he or she lives within five miles of me, to determine what is the probability that I need to contact four people, the following calculation must be performed:
0.45 x 0.45 x 0.45 = X
0.2025 x 0.45 = X
0.091125 = X
Therefore, the probability that I need to contact four people is 9.11%.

R
Please help me solve this
Answer:
x=38
Step-by-step explanation:
First, know that the sum of the angles in a triangle is 180.
Then, add the angles. 2x+38+x+x-10.
Make them equal to 180.
2x+38+x+x-10=180
Simplify.
4x+28=180
Subtract 28 from 180.
4x=152
Divide 4 from 152 to make x alone.
x=38
There you go!
