Answer:

m=-\frac{1}{8}

Step-by-step explanation:

The slope formula is m=\frac{rise}{run}, or m=\frac{y2-y1}{x2-x1}.

Plug in the coordinates into the formula.

\frac{4-5}{1-9} = \frac{-1}{-8} =-\frac{1}{8}

m=-\frac{1}{8}

The slope of the line that contains the points (9,4) and (1,5) is -\frac{1}{8}

Circle F is congruent to circle J, and ∠EFD ≅ ∠GJH. Circles F and J are congruent. Line segments F E and F D are radii. A line c
Rzqust [24]

Answer:

mGH=80^\circ

Step-by-step explanation:

Circle F and J are congruent.

\angle DFE \cong \angle GJH

Given that: m∠DFE = 80°

DFE is the central angle of the circle F.

The measure of arc GH is equal to the central angle of Circle J.

Since both circles are congruent

mGH=\angle DFE = 80^\circ

The measure of arc GH is 80 degrees.

The height of a cylinder is 5 centimeters. The circumference of the base of the cylinder is 16 centimeters. Find the lateral sur
ad-work [718]

The lateral surface area of the cylinder = 80 sq cm.

Step-by-step explanation:

Given,

The circumference of the base of the cylinder is 16 cm

So, 2 X pi X r = 16 cm ( where r be the radius of the base)

Now, the lateral surface of the cylinder = 2 X pi X r X H ( where H be the height = 5 cm)

= 16 X 5 sq cm

= 80 sq cm

Hope it helps you.

Gemiola [76]

Answer:

C. He should run a T-test, and approximating it with a normal distribution would be inappropriate.

Step-by-step explanation:

We are told that the standard deviation is unknown.

Now in statistics, when we know the standard deviation, then we use a Z-test but when we don't know the standard deviation, then we will use a t-test.

Now, the t-test assumes a normal distribution for difference in mean of samples but it doesn't assume so for population.

Thus, we will run a t-test and doesn't need to approximate with a normal distribution.
