Answer:

Cost for 25 songs: $23.50

Cost for s songs: .50(s) + 11

Step-by-step explanation:

To solve this problem, we can make an equation in slope-intercept form:

y = mx + b

y represents the total amount of $.

m represents the cost of each song downloaded, or $.50

x represents the number of songs, or 's'

b represents the $11, or the constant.

We have the equation:

y = .50(x) + 11

If Angel downloaded 25 songs, we have the equation:

y = .50(25) + 11

We get y = $23.50

I hope this helps I found the answer

Answer:

3400 ft-lbs

Step-by-step explanation:

The Workdone in lifting the rope :

Number of feet = x

Distance = 25 feets

2.5x + 35

Taking the integral :

∫2.5x + 35 dx at x = 40

Integrating, we have :

1/2(2.5x² ) + 35x at x = 40

1/2(2.5(40)²) + 35(40)

1/2(4000) + 1400

2000 + 1400

= 3400

Hence, Workdone in lifting the rope = 3400 ft-lbs

Answer:

3/11

Step-by-step explanation:

First find the slope of the line

m = (y2-y1)/(x2-x1)

    = ( 7 - -4)/(2 - 5)

    = (7+4)/(2-5)

   =11/ -3

We want a line that is perpendicular, so it is the negative reciprocal

-1 / ( -11/3)

+3/11

A line that is perpendicular will have a slope that is 3/11

Answer:

6 1/4

Step-by-step explanation:

When you look at the bar graph at the top, you will see that there are 5 of 1 1/4.

If you multiply 5 by 5/4 (which is 1 1/4 converted to an improper fraction), you get 25/4. To convert that to a mixed number, divide 25 by 4 and put the remainder over 4. The final answer should be 6 1/4.

For the X's, just count how many of each number is in the graph above. For example, there should be 2 X's over 1, 5 X's over 1 1/4, 2 X's over 1 1/2, and 2 X's over 1 3/4.

There should be 2 x's for 1, 5 x's for 1 1/4, 2 x's for 1 1/2, 2x's for 1 3/4, and zero x's for 2.

Answer:

x = 14

y = 23

Step-by-step explanation:

x = first number

y = second and greater number

x + y = 37 ⇒ y = 37 - x

y + 5 = 2x

Substitution:

(37 - x) + 5 = 2x

42 - x = 2x

3x = 42

x = 14

y = 37 - (14)

y = 23

Answer:

There is sufficient evidence. A further explanation is provided below.

Step-by-step explanation:

According to the question,

The alternative as well as null hypothesis will be:

[tex]H_0:\mu = 16[/tex]

[tex]H_a:\mu>16[/tex]

The test statistics will be:

⇒ [tex]z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }[/tex]

By putting the values, we get

⇒    [tex]=\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }[/tex]

⇒    [tex]=\frac{\frac{0.06}{0.24} }{\sqrt{96} }[/tex]

⇒    [tex]=2.45[/tex]

Or,

The p-value will be:

= 0.0071

i.e.,

⇒ [tex]p-value< \alpha[/tex]

Thus the above is the correct answer.

Answer:

[tex]m = - 28[/tex]

Step-by-step explanation:

[tex] \frac{ - 3}{7} m = 12[/tex]

[tex] \frac{ - 7}{3} ( \frac{ - 3}{7})m = \frac{ - 7}{3} \times 12[/tex]

[tex] \frac{ - 1}{3} ( - 3)m = \frac{ - 7}{3} \times 12[/tex]

[tex] - 1( - 1)m = \frac{ - 7}{3} \times 12[/tex]

[tex]1 \times m = \frac{ - 7}{3} \times 12[/tex]

[tex]m = \frac{ - 7}{3} \times 12[/tex]

[tex]m = \frac{ - 7}{3} \times 12[/tex]

[tex]m = \frac{ - 7}{3} (3 \times 4)[/tex]

[tex]m = - 28[/tex]

Answer:

$4080 / 30days

Step-by-step explanation:

In 7 days, Kendall earns $952

In 1 day, she will earn $952 ÷ 7 = $136

Therefore, the rate (r) at which she earns is $136/day. i.e

r =  $136/day               ---------------(i)

To write the rate as a fraction with 30 in the denominator, we multiply both the numerator and denominator of equation (i) by 30 as follows;

r =  $(136x30) / 30 day

r = $4080/30days

Step-by-step explanation:

A) A skewed distribution in a dataset is when the median is not equal to the mean in such a manner that the bell curve is tilted to the left or right.

B) If in a data set, there are outliers which are extremely large or extremely small in comparison to other values in that same dataset, then we can say that such a curve will be pulled towards the outlier and thus the distribution is skewed.

Also, if the curve is inclined to the left, it means there are few extreme values to the left and is is negatively skewed.

Similarly, if the curve is inclined to the right, it means there are few extreme values to the right and is positively skewed.

C) Example of a research question is;

If in a developed country where the poverty level is about 0%, if we collect the data of income of the households, we will discover majority of people with average income and very few people with extreme high levels of income. This condition means the data to is positively skewed.
