Lucy brought 4 of her scarves to a secondhand store to sell. She was paid the same amount
of cash for each scarf. Before she left, Lucy spent $10.50 of her earnings on a used sweater.
She had $7.50 remaining. What was the value of each scarf?

Answers

The value of each scarf from the sales will be $4.50.

Since Lucy spent $10.50 of her earnings on a used sweater and she had $7.50 remaining, the total amount that she made from the sales will be:

= $10.50 + $7.50

= $18.00

Since she sold 4 scarves, the cost of each scarf will be:

= $18.00 / 4

= $4.50

Therefore, the value of each scarf will be $4.50.

e. A set of observations has a mean of 9.0 and standard deviation 4.0. Another set of 20 observations has a mean of 10.0. Given the standard deviation of the combined set of 35 observations is 3.0, find the variance of the second set.

Answers

From the combined standard deviation, with the mean, and standard

deviation of the data sets, the required variance can be found.

[tex]\underline{\mathrm{The \ variance \ of \ the \ second \ set \ is} \ 4\dfrac{5}{28}}[/tex]

Reasons:

The given data information are;

Mean of the first set of observation, [tex]\overline x_1[/tex] = 9.0

Standard deviation of the the first set, σ₁ = 4.0

Sample size of second observation, n₂ = 20

Mean of second sample, [tex]\overline x_2[/tex] = 10

Standard deviation of the combined set, σ₁₂ = 3.0

Sample size of combined set of observation, n₂ = 35

Solution:

The number of elements in the second sample, n₁ = 35 - 20 = 15

The standard deviation of the combined set is given by the formula;

[tex]{\sigma_{12}} = \mathbf{\sqrt{\dfrac{n_1 \cdot \left ( \sigma^2_{1}-d_1^2 \right ) + n_2 \cdot \left ( \sigma^2_{2}-d_2^2 \right )}{n_{1}+n_{2}}}}[/tex]

Where;

[tex]\overline x_{12} =\mathbf{\dfrac{n_1 \cdot \overline x_1 +n_2 \cdot \overline x_2 }{n_1 + n_2}}[/tex]

Therefore;

[tex]\overline x_{12} =\dfrac{15 \times 9.0 +20 \times10.0 }{15 + 20} = \dfrac{67}{7}[/tex]

d₁ = [tex]\mathbf{\overline x_{12}}[/tex] - [tex]\mathbf{\overline x_1}[/tex]

[tex]d_1 = \dfrac{67}{7} - 9.0 = \dfrac{4}{7}[/tex]

d₂ = [tex]\mathbf{\overline x_{12}}[/tex] - [tex]\mathbf{\overline x_2}[/tex]

[tex]d_2 = \dfrac{67}{7} - 10.0 = -\dfrac{3}{7}[/tex]

Therefore;

[tex]3=\sqrt{\dfrac{15 \times \left ( 4.0^2-\left(\dfrac{4}{7}\right) ^2 \right ) + 20 \cdot \left ( \sigma^2_{2}-\left(-\dfrac{3}{7}\right) ^2 \right )}{15+20}}[/tex]

Solving gives;

[tex]Variance, \ \sigma^2_2 = \mathbf{\dfrac{{117} }{28}}[/tex]

[tex]\mathrm{The \ variance \ of \ the \ second \ set, \ \sigma_2^2} = \dfrac{{117} }{28} = 4\dfrac{5}{28}[/tex]

What is an equation of the line that passes through the point (-2,7)(−2,7) and is perpendicular to the line x-4y=24x−4y=24?

Answers

9514 1404 393

Answer:

  4x +y = -1

Step-by-step explanation:

The equation of the perpendicular line can be written by ...

swapping the x- and y-coefficients, negating one of themchoosing a new constant so the line goes through the given point.

The x- and y-coefficients in the given equation are 1 and -4, respectively. Since we want the leading coefficient positive, it is convenient to use 4 and 1 as the coefficients in the new equation. The constant can be found by substituting (x, y) = (-2, 7) to see what it is.

  4x +y = 4(-2) +7 = -1

The desired perpendicular line has an equation ...

2. Kirk is reading a science fiction novel. After his first 20 minutes of reading, he sees that he's read 32 pages of
the book. If the book is 375 pages long, which of the following is closest to the total time it will take him to
finish the book?

Answers

20 mins = 32 pages
375 pages / 32 = 11.7
11.7 x 20mins = 3.9 hours so 234 minutes

It will takes him 234 minutes to read 375 pages

The total time that should be taken by him to finish the book is 3.9 hours.

Given that,

There are 20 minutes of reading for 32 pages of the book.Now there are 375 pages.

Based on the above information, the time taken should be

[tex]= 375 \times 20 \div 32[/tex]

= 234.375 minutes

Now in hours it should be

[tex]= 234.375 \div 60[/tex]

= 3.9 hours

Therefore we can conclude that the total time that should be taken by him to finish the book is 3.9 hours.
