Mr. Piper is driving Roddy and Scott home from school. They both want to ride in the front seat. How can he make a fair decision

bagirrra123 [75]

Answer:

A.Put each person's name on a separate piece of paper in a bag. Randomly draw the winning name; and D.Roll a number cube. If it lands on an even number, Roddy wins. If it lands on an odd number, Scott wins.

Step-by-step explanation:

In order for it to be a fair decision, both boys have to have an equal chance of being selected.

For choice A, drawing their names from a bag, both names are equally likely to be chosen; that makes this fair.

For choice B, there is 1 way to get both heads when flipping a coin. There are 2 ways to get heads and tails when flipping a coin. This gives Scott a greater chance, so this is not fair.

For choice C, there are 2 ways to get a 1 or a 2. There are 4 ways to get anything else. This gives Scott a greater chance, so this is not fair.

For choice D, there are 3 even numbers and 3 odd numbers. Both boys have an equal chance, so this is fair.

The the surface area of a cylinder with radius R and height H is twice the product of Pi and the square of the radius plus twice

Y_Kistochka [10]

Concept:

(1) Curved surface area of cylinder = Circumference of the base × Height of cylinder

(2) Area of the base = Area of circle = π × (radius)²

(3) Circumference of the base = 2×π× (radius)

Consider a right circular cylinder as given in attached figure

Its height (AB) = H

Its radius (OC) = R

Now, we shall calculate the curved surface area of the cylinder (CSA)

(CSA) = Circumference of the base × Height of cylinder

(CSA) = 2×π×R × H = 2πRH -------(i)

Again, we shall calculate the area of the top and bottom circles

Area of the top and bottom (A) = 2× Area of circle

(A) =2×[ π × (radius)²]

or, (A) = 2×π×R² = 2πR²------------(ii)

Now, we shall calculate the surface area or total surface area of the cylinder.

SA = CSA + A

SA = 2πRH + 2πR²

or, SA = 2πR² + 2πRH

This is the required equation.

HELP PLS I HAVE 2 MINUTES IF NOT SHES GONNA CALL MY MOM

alukav5142 [94]

Answer:

a) p = -84

b) m = 23

Step-by-step explanation:

p = -4

a = 19 + 2p

⇒ 19 + 2 x -4

⇒ -84

m = 3

$m^{3}$ - 4

⇒ $3^{3}$ - 4

⇒ 23
