Answer: The correct answer is the third option, (-3,-4).
Step-by-step explanation: You plug in 2x + 2 for y, given that y = 2x + 2.
2x+2 = x - 1
x = -3
Now, you plug in -3 for x in an equation.
y = -3 - 1
y = -4.
(-3, -4)

Step-by-step explanation:
100 sq ft=1200
1109sq ft=?
1109*1200/100=13308
what is the standard deviation and variance of 10, 10, 10, 10, 13, 20, 23, 32, 32, 32, 32, 47, 50, 53, 60, 60, 63, 72, 72, 72, 7

Answer:
bro/sis through this solution u can solve ur values
Step-by-step explanation:
To calculate the variance, you first subtract the mean from each number and then square the results to find the squared differences. You then find the average of those squared differences. The result is the variance. The standard deviation is a measure of how spread out the numbers in a distribution are.

-9x+5<17 answer x >-4/3 how I do to it
subtract -5 from both side and you get 12. so it be -9x<12
than you divide -9 from both side because you want x by it self you get -4/3 but you have to flip the sign since is negavite and you will be left over with ×>-4/3
I will take a go at this. Imagine you had 10 chairs to put people in, and you had 10 people. For the first chair, you can pick out of 10 people, for the second chair, you have 9 people to pick from, and so on until the last chair, where you don't have a choice. So, to find the possible ways you can sit people in the chairs, you do 10*9*8*7*6*5*4*3*2*1, or you can denote it as 10!, where ! means factorial. So you get 3628800, and at first you might think that would be the answer, but we are talking about a circular arrangement here. So, two arrangements would be counted as different just because it turns by one person (Shown in picture). So since we dont count the first one, it should just be 9! instead of 10! And 9! equals 362880 (One less zero than the other answer). That should be the right answer
