The area of the living room carpet was s 262.5 square feet. If the width of the room is 21 feet, then what is the length.


Please help, I’m taking an online test, I need it, quick. :)

(15 points!)

Answers

Answer 1
The length would be 12.5 feet.

A rectangle’s area is calculated with the formula:

A = L * W

To find the length, all we have to do is divide the area (A) by the width (W).

We get the equation:

262.5/21 = L

262.5/21 = 12

L = 12

Question

The data in this question will be utilized for the next three questions. The number of pets a group of students has, are given below.

Number of pets:        0-2    2-4   4-6   6-8   8-10   10-12    12-14

Number of students:  1        2      1        5       6         2           3

Calculate

(1) Mean      (2) Sample Variance    (3) Sample Standard Deviation

Answer:

[tex](1)[/tex] [tex]\bar x = 8.1[/tex]

[tex](2)[/tex] [tex]\sigma^2 = 6.341[/tex]

[tex](3)[/tex] [tex]\sigma = 2.518[/tex]

Step-by-step explanation:

Given

The above data

First, we calculate the class midpoint (x)

Pets:  [tex]0-2[/tex]    [tex]2-4[/tex]   [tex]4-6[/tex]   [tex]6-8[/tex]   [tex]8-10[/tex]   [tex]10-12[/tex]    [tex]12-14[/tex]

x           1           3          5       7           9          11          13

f:           1            2         1        5           6         2           3

The class midpoint (x) is calculated by the average of each group.

For pets: 0 - 2.

[tex]x = \frac{0 + 2}{2}= \frac{2}{2} = 1[/tex]

The same is done for other groups.

Solving (a): Mean

[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]

This gives:

[tex]\bar x = \frac{1 * 1 + 3 * 2 + 5 * 1 + 7 * 5 + 9 * 6 + 11 * 2 + 13 * 3}{1 + 2 + 1 + 5 + 6 + 2 + 3}[/tex]

[tex]\bar x = \frac{162}{20}[/tex]

[tex]\bar x = 8.1[/tex]

Solving (b): Sample Variance

This is calculated as:

[tex]\sigma^2 = \frac{\sum(x_i - \bar x)^2}{\sum f - 1}[/tex]

So:

[tex]\sigma^2 = \frac{(1 - 8.1)^2+(3 - 8.1)^2+(5 - 8.1)^2+(7 - 8.1)^2+(9 - 8.1)^2+(11 - 8.1)^2+(13 - 8.1)^2}{20 - 1}[/tex]

[tex]\sigma^2 = \frac{120.47}{19}[/tex]

[tex]\sigma^2 = 6.341[/tex]

Solving (c): The sample standard deviation

This is calculated as:

[tex]\sigma = \sqrt{\sigma^2[/tex]

[tex]\sigma = \sqrt{6.341[/tex]

[tex]\sigma = 2.518[/tex]

We need to find the value of the given expression 6a+4b−6 when a = 1 and b = 3

Put a = 1 and b = 3 in the above expression.

6a+4b−6 = 6(1) +4(3) -6

= 6+12-6

= 12

So, the value of the given expression is equal to 12.

Answer:

  m^2 = 35/9

Step-by-step explanation:

The line will be tangent to the ellipse where there is one point of intersection between the line and the ellipse. We can find that case by looking at the discriminant of the quadratic.

  x^2 +9(mx +2)^2 = 1

  x^2 +9(m^2x^2 +4mx +4) = 1

  (9m^2 +1)x^2+36mx +35 = 0 . . . . subtract 1, collect terms

__

Then the discriminant is ...

  (36m)^2 -4(9m^2 +1)(35)

We want it to be zero, so we have ...

  1296m^2 -1260m^2 -140 = 0 . . . . eliminate parentheses

  36m^2 = 140 . . . . . . . . . . . . . . . add 140

  m^2 = 140/36 . . . . . . . . . . . . divide by 36

  m^2 = 35/9

Triangle QRS was dilated using the dilation rule DP,4.

Point P is the center of dilation. Triangle Q R S is dilated to create triangle Q prime R prime S prime. The length of P R is 3.

Answers

Using the dilation rule, the length of P'R' is: C. 12 units.

What is Dilation?Dilation, as a type of transformation, is the enlargement or reduction of a shape to create a new image which is similar to the original image.If the scale factor is a whole number, it means it's an enlargement, if fraction, it means it is a reduction.

Given that the scale factor of dilation is 4, and PR is 3.

Therefore:

P'R' = 4(PR)

P'R' = 4(3)

P'R' = 12 units.

Therefore, using the dilation rule, the length of P'R' is: C. 12 units.
