Answer:
y = 26/7 or ≈ 3.71
Step-by-step explanation:
3y + 4y= 26
3y + 4y = 7y so,
7y = 26
Divide both side by 7, we got:
y = 26/7 or ≈ 3.71
Hope this helped :3
Answer:
5
Step-by-step explanation:
The slope is given by
m = ( y2-y1)/(x2-x1)
We can use any two sets of points. I like to use the first and the last
m = (15-0)/(4-1)
m = (15/3)
= 5
So,
The slope-intercept form is as follows:
y = mx + b
"m" is the slope, and "b" is the y-intercept. The y-intercept for this equation is (0,b).
Our equation is
That means that
is the slope, and -3 is the y-intercept.
The tarpon would be 121 pounds and the permit would be 11 pounds , add those (121+11=132) and get 132
The standard deviation of a sample is proportional to 1/√N where N is the sample size. In this case we are decreasing N by half, so we can write:
1/√(N/2) = √2 / √N
If we say that our standard deviation is proportional to 1/√N, the difference that occurred from decreasing the sample size by half resulted in an increase in the standard deviation by a factor of √2.
Therefore, the standard deviation is multiplied by √2.
