How do you find the height of this trapezoid?​

Answer:

75

Step-by-step explanation:

Because to find a complementary angle you take 90 and subtract it from the angle you already have, then that would be your answer. Complimentary angles are a pair of angles that add up to 90.

Answer:

volume = 11,664 units cubed

Step-by-step explanation:

2[tex]x^{2}[/tex] times 3 = bottom and sides

[tex]x^{2}[/tex] times 2 = ends

A = 6[tex]x^{2}[/tex] + 2[tex]x^{2}[/tex] = 8[tex]x^{2}[/tex]

2592 = A

2592/8 = 8[tex]x^{2}[/tex]/8

324 = [tex]x^{2}[/tex]

take square root of both sides

18 = x

so volume = length times width times height

2(18) times 18 times 18 = 11664

11664 units cubed

Step-by-step explanation:

The formula for circumference is C = 2[tex]\pi[/tex]r. When plugging in these values, 2 x 3.14 x 4.5 is equal to 28.26.

Circumference of her garden is 28.26 m. So, Option 'A' is the correct answer to the following question.

What information do we have?

Radius of circular garden = 4.5 m

Circumference of her garden = circumference of circle

So,

Circumference of her garden = 2πr

Circumference of her garden = 2(3.14)(4.5)

Circumference of her garden = 28.26 m

Answer: Is there a total for how many kids like each? If there isn't than this is how I would solve it. For percentage purposes let's say there are 100 students. 50 like math, 50 like science. Half of the students who like math also like science, which means 75 percent of the school likes science. A third of students who like science also like math, and since 75 percent of the school of 100 children likes science, that would mean 1/3 of that is 25, which would mean 75 percentof all students like math. Hence the ratio, I believe, is 1 to 1.

Answer:

y = x2 + x - 20 factors into

y = (x +5) * (x -4)

Step-by-step explanation:

Answer:

y = (x + 5)(x - 4)

Step-by-step explanation:

Given

y = x² + x - 20

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (+ 1)

The factors are + 5 and - 4, since

5 × - 4 = - 20 and 5 - 4 = + 1, thus

x² + x - 20 = (x + 5)(x - 4)

0.5 => 5/10 => 1/2

12.3 => 123/10

0.07 => 7/100

0.625 => 625/1000 => 25/40 => 5/8

Answer:

see below

Step-by-step explanation:

0.5, 5/10 = 1/2

12.3 = 12 3/10

0.07 = 07/100

0.625=625/1000 =5/8

                                  = 22.94 square cm              

Answer:

option B

Step-by-step explanation:

[tex]P(x =x) [{\frac{1}{6} ;x =1,2,3...6][/tex]

[tex]E (x) = \frac{6+1}{2} =\frac{7}{2} =3.5\\\\E(x)=3.5[/tex]

Given random experiment of tossing of 6 sided dice is follow above distribution

Therefore, suppose x₁, x₂ ...x₁₀ are 10 independent and indentical random variable which represent first 10 rolls

Average of first 10 rows equals

[tex]\bar x_1 =\frac{ \sum ^{10}_{i=1}xi}{10}[/tex]

[tex]E(\bar x_1)=\frac{ \sum ^{10}_{i=1}E(x_1)}{10} \\\\=\frac{10(3.5)}{10} \\\\=3.5\\\\E(\bar x_1) = 3.5----(1)[/tex]

now suppose ,

x₁₁,x₁₂, ...x₁₅ are 5 independent and identical random variable which represent last 5 roll

average of last 5 roll is

[tex]E(\bar x_2)= \frac{ \sum ^{5}_{i=1}xi}{5} \\\\= \frac{5 \times(3.5)}{5} \\\\=3.5[/tex]

Therefore,[tex]\bar x_1 - \bar x_2[/tex]

3.5 - 3.5 = 0

The mean [tex]\mu(\bar{x_1}-\bar{x_2})[/tex]  of the sampling distribution of the difference in sample means [tex](\bar{x_1}-\bar{x_2})[/tex] is 0 and this can be determined by using the formula of the average mean.

Given:

The average mean of the first ten rolls is given by the formula:

[tex]\rm E(\bar{x_1}) = \dfrac{\sum^{10}_{i=1}(x_1)}{10}[/tex]

Now, put the values of known terms in the above equation.

[tex]\rm E(\bar{x_1})=\dfrac{10\times 3.5}{10}[/tex]

[tex]\rm E(\bar{x_1})={3.5}[/tex]

The average mean of the remaining five rolls is given by the formula:

[tex]\rm E(\bar{x_2}) = \dfrac{\sum^{5}_{i=1}(x_i)}{5}[/tex]

Now, put the values of known terms in the above equation.

[tex]\rm E(\bar{x_1})=\dfrac{5\times 3.5}{5}[/tex]

[tex]\rm E(\bar{x_1})={3.5}[/tex]

Now, [tex](\bar{x_1}-\bar{x_2}) = 3.5 - 3.5 = 0[/tex].

The mean [tex]\mu(\bar{x_1}-\bar{x_2})[/tex]  of the sampling distribution of the difference in sample means [tex](\bar{x_1}-\bar{x_2})[/tex] is 0.

Step-by-step explanation:

If quadrilateral ABCD is the result of a reflection of quadrilateral LMNO over the line.

Then both the quadrilaterals are congruent.

To find the line segment in the image corresponds to NO in the pre-image, just check the order of the letters in the name of quadrilaterals.

Also, In reflection image and its pre-image are equidistant from the line of reflection

hence, CD is the line segment in the image corresponds to NO in the pre-image.
