Answer:

There are 220 boys in the course.

Step-by-step explanation:

If we group the five boys and four girls together, there would be 44 (396/9) groups of nine people. Since there are five boys in every group, you would do 44*5 which is 220.

Answer:

220 boys

Step-by-step explanation:

boys:girls

5:4

396 total

(5x44)+(4x44)=396

220+176=396

220 boys

Answer:

9.8

Step-by-step explanation:

Step-by-step explanation:

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] {5}^{2} + {b}^{2} = {11}^{2} [/tex]

[tex] {b}^{2} = {11}^{2} - {5}^{2} [/tex]

[tex] {b}^{2} = 121 - 25[/tex]

[tex] {b}^{2} = 96[/tex]

[tex] \sqrt{b} = \sqrt{96} [/tex]

[tex]b = 9.78[/tex]

Answer:

360°

Step-by-step explanation:

xjjdjdjdjedjejdjej

hypotenuse side = 12

height = √12^2 - 6^2

          = √144 - 36

          = √108

          = 10.39

area of one triangle = 1 / 2 bh

b = base

h = height

area of one triangle = 1 / 2 × 6 × 10.39

area of one triangle = 31.17 unit^2

area of 2 triangle = 2(31.17) = 62.34 unit^2

area of non shaded sector.

area of the sector = 120 / 360 × 3.14 × 6^2

area of the sector = 37.68 units^2

area of the shaded portion = 62.34 - 37.68

                                            = 24.66 unit^2

Answer:

675 in³

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

V = lbh ( lis length, b is breadth and h the height )

Here l = 15, b = 5 and h = 9 , then

V = 15 × 5 × 9 = 675 in³

Answer: 3000$ in 9% account

Step-by-step explanation: sums in accounts are x and (4000-x)

Interests are 0.09x and 0.10(4000-x) = 400-0.1x

Now you get 0.09x -0.1x + 400 = 370

Then -0.01x = -30 and x= 3000

Answer:

66/400

Step-by-step explanation:

Answer:

i) The variation equation     H =  k L

ii) The value of H = 20

iii) C)  H = k L

Step-by-step explanation:

Step(i):-

Given that H varies directly as L

                    H ∝ L

                   H =  k L

Given that H =30 and L = 60

          ⇒   30 = k (60)

            [tex]k = \frac{30}{60} = \frac{1}{2}[/tex]

Step(ii):-

Given that L = 40

The variation of the equation = H = k L ...(i)

 put L = 40 in equation (i)

 [tex]H = \frac{1}{2} X 40 = 20[/tex]

Answer:

Surface area of cube = 504.84 cm²

Step-by-step explanation:

Given:

Sum of all sides = 110.4 cm

Find:

Surface area of cube

Computation:

Sum of all sides = Perimeter of cube

Perimeter of cube = 12 x side

12 x side = 110.4

Side = 110.4 / 12

Side = 9.2 cm

Surface area of cube = 6 x Side²

Surface area of cube = 6 x 9.2²

Surface area of cube = 6 x 84.64

Surface area of cube = 504.84 cm²

Answer:

For the restaurant that charges 95 cents, the z-score is -4.29.

For the restaurant that charges $1, the z-score is -3.57.

For the restaurant that charges $1.35, the z-score is 1.43

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The average cost of a glass of iced tea is $1.25 with a standard deviation of 7c.

This means that [tex]\mu = 1.25, \sigma = 0.07[/tex]

Restaurant that charges 95 cents:

The z-score is found when X = 0.95. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0.95 - 1.25}{0.07}[/tex]

[tex]Z = -4.29[/tex]

For the restaurant that charges 95 cents, the z-score is -4.29.

Restaurant that charges $1:.

X = 1

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1 - 1.25}{0.07}[/tex]

[tex]Z = -3.57[/tex]

For the restaurant that charges $1, the z-score is -3.57.

Restaurant that charges $1.35:

X = 1.35

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1.35 - 1.25}{0.07}[/tex]

[tex]Z = 1.43[/tex]

For the restaurant that charges $1.35, the z-score is 1.43
