Answer:

n^2/(n + 1)

Step-by-step explanation:

The numerators are the squares of the sequence numbers 1^1  2^2  3^2....

The denominators are the  sequence numbers + 1, so the nth term is

n^2/(n + 1).

Answer:

(-5, -10)

Step-by-step explanation:

(5, -10) is in quadrant 4.

When it reflects on the y-axis, it lands in quadrant 3.

Quadrant 3 is all negative coordinates.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

Reflected along the y-axis from IV Quadrant to II Quadrant

The coordinate will change using the form as,

(x, -y) → (-x, -y)

The coordinate of the reflected point is (-5, -10)

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

Coordinates = (5, -10)

This is in IV Quadrant

If it is reflected across the y-axis.

(5, -10) will be in the III Quadrant.

Now,

The y-coordinate will remain the same but the x-coordinate will change its sign.

The coordinate will change using the form as,

(x, -y) → (-x, -y)

(5, -10) → (-5, -10)

Thus,

The coordinates of the reflected point is (-5, -10)

Where you plug in (-8,5) at your and x1. Then you do the Algebra.

Answer: y=-3/2x-13/2

Step-by-step explanation:

To find a line parallel to the given line, we know that the two equations must have the same slope. We first want to find the slope of the given equation.

3x+2y=9             [subtract both sides by 3x]

2y=-3x+9            [divide both sides by 2]

y=-3/2x+9/2

Now, we know the slope if -3/2. All we have to do is plug in the given point to find the y-intercept.

-5=-3/2(-1)+b      [multiply]

-5=3/2+b            [subtract both sides by 3/2]

b=-13/2

Now, we know the equation is y=-3/2x-13/2.

The question is missing some parts. Here is the complete question.

The random variable X takes on the values of 2, 5, n and 15. The probability distribution of X is shown in the table below.

The expected value of X is 9.1. What is the value of n?

a) 8

b) 8.52

c) 10

d) 12

e) 14.4

Answer: d) 12

Step-by-step explanation: In a probability distribution, Expected Value is the average (or mean) value a distribution can assume.

The Expected Value, E(X), can be determine by:

[tex]E(X)=\Sigma xP(x)[/tex]

in which

x is how many times an event happens

P(x) is the probability of an event happening

The table below n is x and expected value is 9.1, then:

[tex]9.1=2*0.1+5*0.4+0.2n+15*0.3[/tex]

[tex]9.1=0.2n+6.7[/tex]

[tex]0.2n=2.4[/tex]

n = 12

Value of n in this probability distribution is 12.

The value of n in the discrete probability distribution given is 12.

The the sum of [P(X) × X] in a discrete probability distribution is the expected value

From the discrete probability table given :

P(X) × X can be expressed as :

(0.1 × 2) + (5 × 0.4) + (15×0.3) + 0.2n = 9.1

0.2 + 2.0 + 4.5 + 0.2n = 9.1

6.7 + 0.2n = 9.1

0.2n = 9.1 - 6.7

0.2n = 2.4

n = 2.4 / 0.2

n = 12

Therefore, the value of n in the table is 12

Answer:

54minutes

Step-by-step explanation:

Let the time taken to clean up be t

Let the number of people cleaning be n

If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;

t = k/n

k is the constant of proportionality

If 3 people work together to clean, and took them 90 minutes, this means

at t = 90, n=3

Substitute

90 = k/3

k = 3×90

k = 270

To et the time it will take 5people to clean, the will say;

t =k/n

t =270/5

t = 54 minutes

Hence it will take 5 people 54minues to clean

Answer:

El dinero que recibió Armando no es suficiente porque recibió $135.000 y tiene que pagar $142.000.

Step-by-step explanation:

Primero, tienes que sumar los gastos para encontrar la cantidad que Armando tiene que pagar:

47.550+69.700+24.750=$142.000

De acuerdo a esto, el total a pagar es $142.000 y Armando recibió $135.000 por lo cual el dinero que recibió no es suficiente porque el total que tiene que pagar es más alto.

Step-by-step explanation:

We want to get (r) alone on one side

A=πr^2

divide each side by π

A/π=r^2

square root each side

√(A/π)=r

r=√(A/π) is the answer to your first question.

now we are given A

r=√((25)/3.14)

put the left side into a calculator

r=2.8216632

Answer:

(a) The amount of SUTA and FUTA taxes that Amazon owes for the first quarter of the year are as follows:

SUTA = $378

FUTA = $56

(b) The amount of SUTA and FUTA taxes that Amazon owes for the second quarter of the year are as follows:

SUTA = $756

FUTA = $112

Step-by-step explanation:

Since there are 52 weeks in a year quarter and 4 quarters in a year, the number of weeks in a quarter can therefore be calculated as follows:

Number of weeks a quarter = Number of weeks in a year / Number of quarters in a year = 52 / 4 = 13

Therefore, quarterly wage of each employee can calculated as follows:

Employee quarterly wage = Employee weekly wage * Number of weeks in a quarter = Employee weekly wage * 13 ………………………………. (1)

We can now proceed as follows:

a. How much SUTA and FUTA tax does Amazon owe for the first quarter of the year?

Using equation (1), we have:

Larry’s quarterly wage = $355 * 13 = $4,615

Curly’s quarterly wage = $460 * 13 = $5,980

Moe’s quarterly wage = $585 * 13 = $7,605

Since only Moe earns more than $7,000 within the first quarter, the amount of SUTA and FUTA taxes owed by Amazon for the first quarter of the year will be calculated based on the Moe’s wage alone as follows:

SUTA = 5.4% * $7,000 = $378

FUTA = (6.2% * $7,000) - SUTA tax = $434 - $378 = $56

Therefore, the amount of SUTA and FUTA taxes that Amazon owes for the first quarter of the year are as follows:

SUTA = $378

FUTA = $56

b. How much SUTA and FUTA tax does Amazon owe for the second quarter of the year? SUTA: $ FUTA: $

Since SUTA and FUTA have been calculated based on first $7,000 of Moe’s quarterly wage in part a above, he will no longer be considered in the calculation for the second quarter.

We therefore proceed as follows:

Larry’s wage for 2 quarters = Larry’s quarterly wage * 2 = $4,615 * 2 = $9,230

Curly’s wage for 2 quarters = Curly’s quarterly wage * 2 = $5,980 * 2 = $11,960

Since both Larry and Curly have earned more than $7,000 within 2 quarters, the amount of SUTA and FUTA taxes owed by Amazon for the second quarter of the year will be calculated based on the first $7,000 of the two of them as follows:

SUTA = 5.4% * $7,000 * 2 = $756

FUTA = (6.2% * $7,000 * 2) - SUTA tax = $868 - $756 = $112

Therefore, the amount of SUTA and FUTA taxes that Amazon owes for the second quarter of the year are as follows:

SUTA = $756

FUTA = $112

Answer:

2x+3y=13 ------(1)

4x-y=-2 -----(2)

Multiply (1) by 2,

=> 4x + 6y = 26. ---(3)

Subtract (2) from (3),

4x - 4x + 6y + y= 26 + 2

7y = 28

y = 4

x = (13-3(4))/2

x = 1/2.
