can you help me with this?

Answers

Answer:

k=45

Step-by-step explanation:

45+2k+k=180

Step 1: Simplify both sides of the equation.

45+2k+k=180

(2k+k)+(45)=180(Combine Like Terms)

3k+45=180

Step 2: Subtract 45 from both sides.

3k+45−45=180−45

3k=135

Step 3: Divide both sides by 3.

3k/3=135/3

k=45

1999 total revenue of a company from music sales and Licensing was 14.2 billion dollars. It was forecasted that this number would continue to drop until it reaches 5.3 million in 2014. Find the percent decrease in music revenue.

Answers

Answer:

62.67%

Step-by-step explanation:

Total revenue of a company from music sales is 14.2 billion dollars in 1999.

It reaches 5.3 million in 2014.

We need to find the percent decrease in music revenue. It can be given by :

[tex]\%=\dfrac{|\text{original value-decrement value}|}{\text{original value}}\times 100\\\\\%=\dfrac{|14.2-5.3|}{14.2}\times 100\\\\\%=62.67[/tex]

So, the percent decrease in music revenue is 62.67%.

Step-by-step explanation:

Use the order of operations pemdas( parenthesis, exponent, multiply, divide, add, subtract)

first do everything within the parenthesis.

3 ( ( 3 (9-2) ) + ( 7 (8-1) ) )

3 ( ( 3 (7) + ( 7 ( 7 ) ) )

Chau rented a truck for one day. There was a base fee of $20.99, and there was an additional charge of 79 cents for each mile driven. Chau had to pay $130.80 when he returned the truck.

For how many miles did he drive the truck?

Answers

Answer:

Chau drove 139 miles

Step-by-step explanation:

Knowing how much Chau spent at the end makes the question much much easier. So what you want to do is take of the base fee ($20.99) off the final amount he had to pay.

$130.80 - $20.99 = $109.81

Now you divide $109.81 by the additional charge ($0.79)

Change the divisor (0.79) to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend (109.81) the same, 2 places to the right.

We then have the equations:

10981 ÷ 79 = 139.000

and therefore:

109.81 ÷ 0.79 = 139.000

Chau drove 139 miles.

Answer:

Step-by-step explanation:

Use the residual plot to determine if this linear model is appropriate.

Answers

Answer:

The linear model is not appropriate.

Step-by-step explanation:

In regression, the difference amid the observed-value of the dependent-variable (y) and the predicted-value ([tex]\hat y[/tex]) is known as the residual (e).

[tex]e=y-\hat y[/tex]

A residual plot is a graphical representation of the residuals on the y-axis and the independent variable on the x-axis. If the data-points on the residual plot are randomly spread around the x-axis, a linear regression model is appropriate for the data. And if the residual plots shows a non-random or a U or inverted U pattern, a nonlinear model is more appropriate for the data.

The residual provided shown an inverted U pattern. That is the points are not scattered around he graph.

Thus, the linear model is not appropriate.

A residual plot for the nutrition data would display the residuals on the y-axis and the age on the x-axis.

The residual plot is not appropriate for a linear model.

From the residual plot (see attachment), we can see that the points on the residual plot follows a curved pattern.

For a residual plot to be a linear model, the points on the plot must be at random on the horizontal axis of the plot.

This means that, the residual plot is not appropriate for a linear model.

a) Cuántas horas tarda en acumularse 1

centímetro de nieve en el jardín de Harper?

0.508 horas o 30.48 minutos

b) Cuántos centímetros de nieve se acumulan por hora?

5 cm

Step-by-step explanation:

a) ¿Cuántas horas se necesitan para acumular 1 pulgada de nieve en el jardín de Harper?

1 pulgada de nieve = 2.54 cm de nieve

d = 5 × h

2.54 = 5 h

h = 2.54 / 5

h = 0.508 hora

Convertir a minutos = 0.508 horas × 60 minutos

= 30.48 minutos.

Por lo tanto, se necesitarían 0.508 horas o 30.48 minutos para acumular 1 pulgada de nieve en el jardín de Harper.

b) ¿Cuántos centímetros de nieve se acumulan por hora?

d = 5 h

Por hora = 1 hora

d = 5 × 1

d = 5 cm

Por tanto, se acumulan 5 cm de nieve por hora.

What is the interquartile range of the following data set?

a.45
b.33
c.27
d.60
(apex)

Answers

Answer:

The interquartile range is 60 ⇒ D

Step-by-step explanation:

The interquartile range is the difference between the upper quartile and the lower quartile

Let us explain how to find the interquartile range

Arrange the number from smallest to greatestFind its median Q1 (the middle number in the set of numbers)Find the lower quartile Q1 which is the median of the set of the numbers before the median Find the upper quartile Q3 which is the median of the set of the numbers after the median Subtract Q1 from Q3 the answer is the interquartile range

Let us do these steps to find it

∵ The data set is {45, 12, 48, 96, 61, 84, 29, 1, 72, 5, 14}

→ Arrange them

∴ The data set is {1, 5, 12, 14, 29, 45, 48, 61, 72, 84, 96}

∵ They are 11 numbers

∴ The middle number is the 6th number (5 before it and 5 after it)

∵ The 6th number is 45

∴ The median is 45

→ Find the lower set (before the median)

∴ The lower set is {1, 5, 12, 14, 29}

→ Find the lower quartile Q1

∵ The lower quartile is the middle number in this set

∵ There are 5 numbers

∴ The middle one is the 3rd

∵ The 3rd is 12

∴ Q1 = 12

→ Find the upper set (after the median)

∴ The upper set is {48, 61, 72, 84, 96}

→ Find the upper quartile Q3

∵ The upper quartile is the middle number in this set

∵ There are 5 numbers

∴ The middle one is the 3rd

∵ The 3rd is 72

∴ Q3 = 72

→ Subtract them to find the interquartile range

∵ The interquartile range = Q3 - Q1

∴ The interquartile range = 72 - 12

∴ The interquartile range = 60

A candy store uses 77.2 grams of sugar each hour. How many grams of sugar will the store use in 10 hours?

Answers

Answer:

The store will use 772 grams of sugar in 10 hours.

Taking into account the rule of three, a candy store uses 772 grams of sugar in 10 hours.

Rule of three

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied.

To solve a direct rule of three, the following formula must be followed, being a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: [tex]x=\frac{cxb}{a}[/tex]

Grams of sugar

The rule of three can be applied as follow: if in 1 hour a candy store uses 77.2 grams of sugar, in 10 hour how many mass is used?

1 hour ⇒ 77.2 grams

10 hours ⇒ x

So: [tex]x=\frac{10 hoursx77.2 grams}{1 hour}[/tex]

Solving:

x= 772 grams

In summary, a candy store uses 772 grams of sugar in 10 hours.
