The ofference of the sample means is 22 and the standard deviation of the difference of the sample means is 10 The difference of the means of the two populations at a 95% confidence interval is t[]​

no not all of them.

step-by-step explanation:

some of them have a square base.

mean, 40.6

step-by-step explanation:

christopher is 272,195 year old

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
