Step-by-step explanation:

Answer:

68

Step-by-step explanation:

Let the number of girls be x.

According to the question,

[tex] \implies \: \dfrac{5}{6} = \dfrac{20}{x} [/tex]

[tex] \implies \: 5x = 20 \times 6[/tex]

[tex] \implies \: 5x = 120[/tex]

[tex] \implies \: x = \cancel\dfrac{120}{5} [/tex]

[tex] \implies \: x = 24[/tex]

[tex] \cal \therefore \: Number \: of \: girls \: are \: 24.[/tex]

Now,

Pupils in the class = Boys + Girls

[tex] \rightarrow20 + 24[/tex]

[tex] \rightarrow44[/tex]

Total number of pupils are 44 .

Answer:

Step-by-step explanation:

1)  

Area) =  area of square + area of triangle

square = 6*6 = 36  

area of equilateral triangle =   ([tex]\sqrt{3}[/tex] / 4) *a^2 = 31.1759

total area = 36 + 31.1759 = 67.1769[tex]in^{2}[/tex]

Perimeter) 6*5 = 30 "

2)

Area)  = upper triangle + lower square

6*[tex]\sqrt{2}[/tex] *sin(45) = 6 cm ( each side is 6)

upper triangle = 1/2*6*6 = 18

lower square = 6*6=36

total area = 38 + 18 = 56 [tex]cm^{2}[/tex]

perimeter = 4*6+6*[tex]\sqrt{2}[/tex] = 32.4852 cm

3)

Area) = left triangle + right rectangle

left triangle = 1/2*3*4   = 6    ( this is the famous 3,4,5 triangle )

rectangle = 8*3 = 24

total area = 24+6=30 [tex]ft^{2}[/tex]

perimeter = 8+5+3+8+3= 27'

Answer:

Step-by-step explanation:

1. The figure can be decomposed into a square and an equilateral triangle. Both have the same side length: 6 in. For an equilateral triangle of side length s, the area is ...

  A = (√3)/4·s²

For a square with side length s, the area is ...

  A = s²

The total of the two areas is ...

  A = ((√3)/4 + 1)s² ≈ 1.433013×(6 in)²

  A ≈ 51.59 in²

__

The perimeter is the sum of the 5 equal side lengths:

  P = 5(6 in)

  P = 30 in

__

2. The hypotenuse of the isosceles right triangle at the top of the figure tells you the side length of the triangle is (6√2)/√2 = 6 cm. The area of the triangle is half that of the square below it, so the total area is ...

  A = (1 +1/2)(6 cm)²

  A = 54 cm²

__

The perimeter is the equivalent of 4 sides of 6 cm and one of 6√2 cm, so is ...

  P = (4 +√2)(6 cm)

  P ≈ 32.49 cm

__

3. The triangle at the left end of the figure has a hypotenuse of 5 and a height of 3. It is recognizable as a 3-4-5 right triangle, so the bottom leg of it is 4 ft long. That makes the bottom side of the trapezoid have a length of 8+4 = 12 ft.

The area of the trapezoid is ...

  A = 1/2(b1 +b2)h

  A = (1/2)(12 ft +8 ft)(3 ft)

  A = 30 ft²

__

The perimeter is the sum of the side lengths. Starting at left and working clockwise, that sum is ...

  P = (5 + 8 + 3 + 12) ft

  P = 28 ft

Answer:

70%

Step-by-step explanation:

The number of students with an April birthday and candles is in the upper left, 14. That’s the “part” Percentage is part/whole x 100.

To figure out the “whole”, you need to add up all the students in the first row of the table, because those are the April birthdays. 14 + 6 = 20

14/20 = 0.7 x 100 = 70%

Answer:

102 x 5 = 100 x 5 = 500

                00 x 5 = 0

              + 2 x 5   =  10

-------------------------------------------

                         510

Answer:

x = 5

Step-by-step explanation:

NOTE: THE 2 SIDES ARE THE SAME LENGTH

THEY HAVE TO BE SMALLER THEN 10

So 10/2 = 5

x = 5

Answer:

Yes it is.

Step-by-step explanation:

Let the AP be a, a+d, a+2d, a+3d and so on, then

4a + 6d = 44 which gives

a = (22–3d)/2 = 11 -1.5d

Assume that the AP has n terms, then nth term is given as :

a + (n-1)d = 11 - 1.5d + (n-1)d = 11 - (n-2.5)d

The second equation then becomes:

(11 - 1.5d)(n-2.5d) = 140

which simplifies to

42n -110d - 6nd + 15d^2 = 560 or put simply

6n = 15d -5 - (5 * 7 * 17)/(d-7)

As n is an integer, so must be 6n and therefore so must be (5*7*17)/(d-7) which means d = 12, 14 or 24

which gives 6n = 56, 120 and 320 respectively.

Again as n is an integer, the only possible answer is n = 20, which occurs when d = 14 and a is -10 which gives us the series -10, 4, 18, 32 .. 256

The terms be a-3d,a-d, a+d,a+3d

Sum = 4*a = 44.

a = 11;

Product

( a-3d)(a+3d) = 140

11*11- 9*d*d = 140

d*d = - 19/9.

Negative. No real common difference.

The meaning of ‘ extreme' is important.

The AP has more than four terms.

a,a+d,a+2d,a+3d,….,a+(n-1)d.

Sum condition

4a + 6d = 44

2a + 3d = 11 eqn-1

Answer:

  2. A'(3, 13)

  4. A''(-3, 13)

  5. No

Step-by-step explanation:

2. The translation is represented by the transformation ...

  (x, y) ⇒ (x-4, y+8)

  A(7, 5) ⇒ A'(7-4, 5+8) = A'(3, 13)

__

4. The reflection is represented by the transformation ...

  (x, y) ⇒ (-x, y)

  A'(3, 13) ⇒ A''(-3, 13)

__

5. No. The location (-3, 13) is not the same as the original location (7, 5).

Answer:

  (a)  Jennifer’s graph is vertically shifted from Matt’s graph.

  neither graph has a maximum

Step-by-step explanation:

Jennifer's equation can be put into vertex form as ...

  f(x) = 2(x^2 +2x +1) -2

  f(x) = 2(x +1)^2 -2 . . . . . . vertex at (-1, -2)

Compared to Matt's graph, Jennifer's will be shifted down 2 units.

__

Both graphs open upward, so the vertices are minimums. Neither graph has a vertex that is a maximum. (The vertex on Matt's graph is the maximum of the two vertices.)

Answer:

Compare the graphs that Jennifer and Matt drew by completing the statements.

* )     Jennifer’s graph is vertically shifted  

2 units down

from Matt’s graph.

** )   Jennifer’s graph is horizontally shifted  

0 units left or right

 from Matt’s graph.

*** )   Jennifer’s graph is  

the same shape as

 Matt’s graph.

**** )   Which graph has a vertex that is a maximum?

Neither Jennifer’s nor Matt’s

Answer:

40/100

Step-by-step explanation:

4/10 can be made into an equivalent fraction by multiplying each number by 10. This is because we need to change the denominator into 100 and 10x10=100.

10(4/10)=40/100

40/100 is the answer

Answer:

The test statistic is z = 2.7.

The pvalue of the test is 0.0035 < 0.05, which means that this sample provides enough evidence to conclude that the average house size has increased in the Hays County since 2010.

Step-by-step explanation:

The average size of a new house built in a Hays county in 2010 was 1,872 square feet. Evidence that it has increased?

This means that the null hypothesis is:

[tex]H_0: \mu = 1872[/tex]

And the alternate hypothesis is:

[tex]H_a: \mu > 1872[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

1872 is tested at the null hypothesis:

This means that [tex]\mu = 1872[/tex]

Sample of 40. The average square footage was 2,031 with a standard deviation of 373 square feet.

This means that [tex]n = 40, X = 2031, \sigma = 373[/tex]

Value of the test-statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{2031 - 1872}{\frac{373}{\sqrt{40}}}[/tex]

[tex]z = 2.7[/tex]

Pvalue and decision:

The pvalue of the test is the probability of finding a sample mean above 2031. This is 1 subtracted by the pvalue of z = 2.7.

Looking at the z-table, z = 2.7 has a pvalue of 0.9965

1 - 0.9965 = 0.0035

The pvalue of the test is 0.0035 < 0.05, which means that this sample provides enough evidence to conclude that the average house size has increased in the Hays County since 2010.

[tex]\frac{1}{16}[/tex]

Step-by-step explanation:

Answer:

1/16

Step-by-step explanation:

Anytime you divide fractions by whole numbers, remember this:

Same, change, reciprocal (flip)

In the equation:

3/4 / 12

KEEP 3/4 as it is.

CHANGE the division sign to a multiplication sign.

FLIP 12/1 to 1/12.

The final equation: 3/4 x 1/12

3/4 x 1/12 = 3/48

3/48 simplified: 1/16

Therefore, 3/4 / 12 = 1/16
