Y = -2x + 8 = x - 4
x + 2x = 8 + 4
3x = 12
x = 4
y = -2(4) + 8 = -8 + 8 = 0
Solution is (4, 0)
Answer:
12
Step-by-step explanation:
Put numbers in order from least to greatest.
8,8,9,9,10,11,13,14,14,14,15,16.
Find the number in the middle.
Because 12 is an even number we have to take the two middle numbers, in this case 11 and 13, add them and then divide that number by 2.
11+13= 24
24 ÷ 2 =12
So the median weight is 12.
Answer:
z = -0.57
Step-by-step explanation:
A z-score indicates how much away is something from the mean so it can be more(above) than the mean or less(below) than the mean.
sampling distribution mean = 0.03
standard error = 0.007
researcher's sample mean = 0.026
z = (0.026 - 0.03)/0.007
z = (-0.004)/0.007
z = -0.57
So that means the researcher's sample mean is 0.57 standard deviation below the sampling distribution mean.
The negative sign above is the indicator of below the mean value.

Please mark Brainliest!!!
Step-by-step explanation:
5y + x - y; use x = 1, and y = 6
You plug the numbers in.
5(6) + 1 - 6
30+1-6
