Answer 1

Answer:

1st and 3rd answer

Step-by-step explanation:

1st answer - Having a sample that is not random does not allow you to generalize the results of the experiment/study to the population because it is not representative of the population in the first place.

3rd answer - The definition of a random sample is that each member of the population has an equal chance of being selected.

Find the surface area of a cone with volume 320pi and height 15 (hint: don't use the height in
the surface area formula.

Answer key :
Either 200 pi or 325 pi
Please help !!!

Answers

Answer:

200π

Step-by-step explanation:

Surface area of a cone  = πr(r+l)

r is the radius

l is the slant height

Volume of the cone = 1/3πr²h

320π = 1/3πr²h

320 = 1/3r²(15)

320 = 5r²

r² = 320/5

r² = 64

r = 8

l² = 15² + 8²

l² = 225 + 64

l² = 289

l = 17

Get the surface area;

S =  πr(r+l)

S =  π8(8+17)

S = π*8*25

S = 200π

Hence the surface area of the cone is 200π

The regression equation for Y is: ŷ = -0.223X + 20.523

What is Linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Sum of X = 15

Sum of Y = 99.27

Mean X = 3

Mean Y = 19.854

The sum of squares (SSX) = 10

The sum of products (SP) = -2.23

Regression Equation = ŷ = bX + a

b = SP/SSₓ = -2.23/10 = -0.223

a = My - bMₓ = 19.85 - (-0.22*3) = 20.523

ŷ = -0.223X + 20.523

Based on records from the past several seasons the probability of the Madison Math Team winning a competition is p(win)-0.875
If they compete in 24 competitions, how many will they win?

Answers

Answer:

They will win 21 games

Step-by-step explanation:

Here, we want to get the number of possible wins

From the question, we have it that the probability that the team will win is 0.875

Now, out of the 24 games, we simply have to multiply their winning probability by the number of games

We have this as;

0.875 * 24 = 21

Hence, out of the 24, 21 will result in a win

2x+3y=15

Simultaneously equations

Answers

Answer:

Step-by-step explanation:

Let's solve your system by substitution.

2x+3y=15;x+y=6

Rewrite equations:

x+y=6;2x+3y=15

Step: Solvex+y=6for x:

x+y=6

x+y+−y=6+−y(Add -y to both sides)

x=−y+6

Step: Substitute−y+6forxin2x+3y=15:

2x+3y=15

2(−y+6)+3y=15

y+12=15(Simplify both sides of the equation)

y+12+−12=15+−12(Add -12 to both sides)

y=3

Step: Substitute3foryinx=−y+6:

x=−y+6

x=−3+6

x=3(Simplify both sides of the equation)

Answer:

x=3 and y=3

Answer:

x = 3, y = 3

Step-by-step explanation:

Given the 2 equations

2x + 3y = 15 → (1)

x + y = 6 → (2)

Multiplying 2) by - 2 and adding to (1) will eliminate x

- 2x - 2y = - 6 → (3)

Add (1) and (3) term by term to eliminate x

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

2x + 3(3) = 15

2x + 9 = 15 ( subtract 9 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

1. Write and solve an inequality that represents the number of months the center could

rent games from NetGames with its $175. Explain the solution in terms of the problem.

Answers

Solution :

Given that the Centre is signing up for a rental game service online rather than buying the game.

The monthly fees and the equipment cost of the two services that is the 'Anytime games' and the 'Netgames' are attached below.

Therefore, the inequality which represent the number that the center can rent the online games from the NetGames is :

175 - 8m ≥ 99

175 - 8m - 99 ≥ 99 - 99    (Subtracting 99 from both side of the inequality)

76 - 8m ≥ 0      (Simplify)

76 - 8m -76 ≥ 0 - 76      (Subtracting 76 from both side of the inequality)

- 8m ≥  - 76 (Simplify)

 8m ≥   76   (removing the minus sign form both sides)

The value of the equation ( x⁶ - x ) / 4y = 1025/4 when x = -4 and y = 4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = ( x⁶ - x ) / 4y   be equation (1)

The value of x = -4

The value of y = 4

Substituting the values of x and y in equation (1) , we get

A = ( ( -4 )⁶ - ( -4 ) ) / ( 4 x 4 )

On simplifying the equation , we get

A = ( 4096 + 4 ) / 16

A = 4100 / 16

A = 1025 / 4

Therefore , the value of A is 1025/4

Hence , the value of the equation is 1025/4
