Let's apply the formula giving the slope:

m=(y2-y1) /(x2-x1) , let's plug:

m= (8-0) / (3-(-1)) ====> m= 2

What is the mean of this data? 7,5,5,3,2,2

Vikentia [17]

Answer:

Step-by-step explanation:

The mean is the average of a data set. It can be found by adding up all of the values in a data set and then dividing it by the number of values in the data set.

The values in this data set;

$7,5,5,3,2,2$

The number of values in this data set,

$6$

Find the mean;

$\frac{sum\ of\ vlaues}{number\ of\ values}$

$=\frac{7+5+5+3+2+2}{6}\\\\=\frac{24}{6}\\\\=4$

The cone and cylinder below have equal surface area

marissa [1.9K]

Answer:

Option B, False

Step-by-step explanation:

Step 1: Get the surface area formulas for both shapes

Surface Area Formula for Cone: $A = \pi * r(r + \sqrt{h^{2} + r^{2}})$

Surface Area Formula for Cylinder: $A = 2\pi rh+2\pi r^{2}$

Step 2: Plug in the values and solve

Cone: $A = \pi * r(r + \sqrt{(3r)^{2} + r^{2}})$

Cone: $A = \pi r^{2} + \pi \sqrt{10}r^{2}$

Cylinder: $A = 2\pi r*r+2\pi r^{2}$

Cylinder: $A=4 \pi r^{2}$

Step 3: Compare

$\pi r^{2} + \pi \sqrt{10}r^{2}\neq 4 \pi r^{2}$

They are not equal, therefore the answer is False.

Answer: Option B, False
