Step-by-step explanation:

No trapezoid is attached; so, I will solve on a general note

The area of a trapezoid is:

[tex]Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height[/tex]

Using the attached image as a point of reference;

The parallel sides are: AD (6cm) and BD (12cm)

The height is 4cm

So, the area is:

[tex]Area = \frac{1}{2} * (6cm + 12cm) * 4cm[/tex]

[tex]Area = 18cm * 2cm[/tex]

[tex]Area = 36cm^2[/tex]

Answer:

m1 = 112 vertical angle

m2 = 180- 112= 68

m3 = 68 vertical with m2

m5 = 112 corresponding with m1

m6 = 68 corresponding with m2

m7 = 68 vertical with m6

m8 = 112 vertical with m5

C.  -1.7

Step-by-step explanation:

Answer:

X<3

Step-by-step explanation:

  6x−6+6<12+6

6x<18

Step 2: Divide both sides by 6.

6 divded by 6 = 1

18 divided by 6= 3

therefore the answer would be

X<3                  

Answer:

x = 1 or less

Step-by-step explanation:

12 - 6 = 6

6x = 6 or less

Divide each side by 6:

6x/6 = 6 or less/6

x = 1 or less

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

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.

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]

Answer:

yes

Step-by-step explanation:

pythagorean formula: sqrt(8^2+6^2) = 10

Answer:

f(- 7) = 17

Answer:

sin A = [tex]\frac{15}{17}[/tex]

cos A = [tex]\frac{8}{17}[/tex]

tan A = [tex]1\frac{7}{8}[/tex]

Step-by-step explanation:

sine = [tex]\frac{ooposite}{hypothenuse}[/tex]

sine A = [tex]\frac{15}{17}[/tex]

cosine = [tex]\frac{adjacent}{hypothenuse}[/tex]

cos A = [tex]\frac{8}{17}[/tex]

tan = [tex]\frac{opposite}{adjacent}[/tex]

tan A = [tex]\frac{15}{8} = 1\frac{7}{8}[/tex]

rise= -2 run= -4 slope= -1/2

Step-by-step explanation:

slope= rise/run

since rise=-2 and run=-4, slope=-2/4, but we have to simplify, so slope=-1/2

Answer:

- 3 < n < 6

Step-by-step explanation:

Given

- 17 < 7n + 4 < 46 ( subtract 4 from each of the intervals )

- 21 < 7n < 42 ( divide each interval by 7 )

- 3 < n < 6

Answer:

x=5

Step-by-step explanation:

hey there

the angles given are corresponding angles meaning that they are congruent

so we set up an equation

23x-5=21x+5

step 1 subtract each side by 5

5-5 cancels out

-5-5=-10

now we have

23x-10=21x

step 2 subtract each side by 23x

21x-23x=-2x

now we have

-2x=-10

step 3 divide each side by 2

-10/-2=5

so we can conclude that

x=5
