Answers

Answer 1

Answer:

second one

Step-by-step explanation:

just multiply by -9 and see which one fits in

Answer 2

Answer:

{1, -9, 81, -729, …}

Step-by-step explanation:

Geometric sequence is basically multiplying the previous number by the constant. So it is 1 x -9 = -9, -9 x -9 = 81, -81 x -9 = -729, and so on.

Ken earned $128 from his part-time job this summer. He spent 25% of his money on games. He is going to donate 1/6 of the remaining money to charity. How much will the charity receive?

A) $15
B) $16
C) $32
D) $80

Please explain how to do it also

Answers

Answer:

B) $16

Step-by-step explanation:

Alright so first you want to take the total amount of money made :

$128

Next you want to find 25% of this number (or 1/4) and subtract it from the total.

So :

128 / 4 = 32

So now we take 128 and subtract 32. (32 = 1/4 or 25% of 128)

128 - 32 = 96

Ken now has $96 left over after spending money on games.

So now that we have this number we need to find 1/6 of it because he took 1/6 of the money after he bought games and put it towards charity.

So :

96 / 6 = 16

16 is equal to 1/6 of his leftover money after games and is the amount the charity received.

B) $16

I hope this helps! :)

If you are confused or have any questions please comment or dm and I would be happy to help.

Answer:

B) $16

Step-by-step explanation:

1. First let's find how much he spent on games. Multiply 0.25 to 188. 0.25 x 128 = 32.

2. Now subtract that amount from the original $128.  128 - 32. = 96.

3. Then, multiply 1/6 from 96. 1/6 x 96 = 16. This $16 is the amount the charity will receive.

determine the relationship between the measures of the given angles

Answers

It's mPVT < mVPT. So, the correct one is b

∠PTV > ∠VPT. This is because the angle opposite to the larger side is greater.

What are angles and dihedral angles? What is equation modelling? In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is a 2 - D image as shown in the question.

It can be concluded that ∠PTV > ∠VPT. This is because the angle opposite to the larger side is greater.

Therefore,  ∠PTV > ∠VPT. This is because the angle opposite to the larger side is greater.

Group of answer choices dbar = the true sample mean difference in jump height mu_d = the true sample mean difference in jump height dbar = the true population mean difference in jump height mu_d = the true population mean difference in jump height

Answers

Answer:

a. mu_d = the true population mean difference in jump height

Step-by-step explanation:

In statistical parlance, observations used for a study could either be randomly chosen points or members of a large group or population, this small chosen observation obtained from a larger group is called the sample, the statistical measures or characteristic of such group is called statistic; while statistical characteristic, computations or measurement of the entire group of observations is called the parameter.

Mean of sample are usually represented with a bar sign on top such as (xbar) ; while mean of a population is represented as μ.

x/5 + 20 = 20.1

5x + 20 = 20.1
​

Answers

Answer:

No solution

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

a) The value of x in equation (a) is x = 0.5.

b) The value of x in equation (b) is x = 0.02.

Let's solve the equations for the value of x:

a. X/5 + 20 = 20.1

Step 1: Subtract 20 from both sides to isolate the term with x:

X/5 = 20.1 - 20

Step 2: Simplify the right side:

X/5 = 0.1

Step 3: To solve for x, multiply both sides by 5:

X = 0.1 * 5

X = 0.5

So, the value of x in equation (a) is x = 0.5.

b. 5x + 20 = 20.1

Step 1: Subtract 20 from both sides to isolate the term with x:

5x = 20.1 - 20

Step 2: Simplify the right side:

5x = 0.1

Step 3: To solve for x, divide both sides by 5:

x = 0.1 / 5

x = 0.02

So, the value of x in equation (b) is x = 0.02.

Number of insect = 2 ;

Number of insect = 3 ;

32 units²

Step-by-step explanation:

this shape is a trapezoid with a height of 4 and bases that are 4 and 12 units in length

formula is: 1/2(height) x (sum of bases)

A = 1/2(4)(4 + 12)

A = 2(16)

A = 32

It’s 32 because 4 x4 is 16, we just answer the square part. Now we are moving on to the triangles on the side. 4 x4 is 16 /2 is 8 then time eight by two bc their are two triangles. So 16 plus 16 is 32

The easiest way for me to find any percentage of a number is to find what 1% is and then multiply by the % amount. So to answer this question I would do 575/100 which is 5.75 and this is 1% then multiply 5.75 by 16 to get 92 so a 16% of 575 is 92. (Double check to make sure I'm correct)

Answers

Answer:

1/7 ;

0.0034

Step-by-step explanation:

Given that:

X = 1/14, 1/7, 3/14

n = number of observations = 3

Since, probability of X is equally likely ;

P(X) = Σp(x) = 1 ; p(x) = 1/n = 1/3

The mean, m ;

Σx*p(x) = (1/3 * 1/14) + (1/3 * 1/7) + (1/3 * 3/14)

= 1/42 + 1/21 + 3/42

= (1 + 2 + 3) / 42

= 6 / 42

= 1/7

The variance :

Σx²*p(x) - m²

((1/3) * (1/14)^2) + ((1/3) * (1/7)^2) + ((1/3) * (3/14)^2) - (1/7)^2

= 0.0238095 - 0.0204081
