Answer:
10. X = 2.75
11. X = 1.61
Hey there, I have the steps listed below but what is the problem asking, I cannot solve it unless it explains the problem. Thank you!
Step-by-step explanation:
10. 5x + 10 + 11x + 2 = 56
16x + 12 = 56
16/16x = 44/16
X = 2.75
11. -1 + 8x + 18x + 5 = 46
26x + 4 = 46
26/26x = 42/26
X = 1.61

Answer:
i cant say since there arent any number lines shown
Step-by-step explanation:
The value of function f(x) = x+4 when x=3 is 7.
By considering given function
f(x) = x+4
f(3)= 3+4
f(3)=7
A mathematical expression, rule, or law that establishes the relationship between an independent variable and a dependent variable (the dependent variable). In mathematics and the sciences, functions are fundamental for constructing physical relationships.
Four broad categories can be used to classify different types of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element.

Answer:
Mean: 13
SD: 
Step-by-step explanation:
To find the mean, you have to add up all of them and divide by the number of them. The sum is 30+30+18 or 78, and there are 6 so the mean is 78 / 6 = 13.
To find the standard deviation, we need to first find the distance from them to the mean. These are 2, 3, 3, 3, 5, and 2. Square these values to get 4, 9, 9, 9, 25, and 4. Now we have to take the mean of this, which is 8+27+25=35+25=60, so the mean is 10 and now we take the square root so the SD is .
