Answer:

-1 (losing a point)

Step-by-step explanation:

it is a probability question

total possible outcomes= 3

favourable outcome(white) = 2

probability of getting a white is 2/3

probability of getting a green is 1/3

so the expected value of the game will be -1

Answer:

132 ft

Step-by-step explanation:

The radius is 21 ft

We want to find the circumference

C = 2 * pi *r

Letting pi = 22/7

C = 2 * 22/7 * 21

C = 132 ft

Answer:

We want to find the circumference

Answer:

90 cm^2

Step-by-step explanation:

The area of a triangle is half of the base times height, so it is 1/2*15*12 = 7.5*12 = 90

Answer:

x ≈ 24.7

Step-by-step explanation:

Using the Sine rule in the triangle , that is

[tex]\frac{x}{sin71}[/tex] = [tex]\frac{15}{sin35}[/tex] ( cross- multiply )

x × sin35° = 15 × sin71° ( divide both sides by sin35° )

x = [tex]\frac{15sin71}{sin35}[/tex] ≈ 24.7 ( to the nearest tenth )

Answer:

The probability that all 3 balls are red is 18.65%, while the probability that all 3 balls are blue is 7.87%.

Step-by-step explanation:

Since a bag contains 8 red balls and 6 blue balls, and Radhika takes three balls at random from the bag, without replacement, to calculate the probability that the three balls are the same color, the following mathematical operations must be performed:

8 + 6 = 14

14 = 100

8 = X

8 x 100/14 = X

800/14 = X

57.14 = X

100 - 57.14 = 42.86

0.5714 ^ 3 = X

0.1865 = X

0.4286 ^ 3 = X

0.0787 = X

Therefore, the probability that all 3 balls are red is 18.65%, while the probability that all 3 balls are blue is 7.87%.

Answer:

4 batches

Step-by-step explanation:

To obtain the number of batches of the recipe that can be made ;

We take the divison of the total amount of strawberry by the amount of strawberry required per batch :

Pounds of strawberry per recipe = 0.75 pound

Total pounds of strawberry = 3.15 pound

= 3.15 / 0.75

= 4.2

We round down :

4.2 batches = 4 batches of the recipe can be made

Answer:

V = (8 in)(5 in)(3 in) = 120 in^3

Step-by-step explanation:

The likeliest name for this shape is "rectangular prism."  Let's assume that the length, L, is 8 in; the width, W, is 5 in; and the height, H, is 3 in.

Then the volume of this rectangular prism is V = L * W * H, or

V = (8 in)(5 in)(3 in) = 120 in^3

Answer:

  ∠GDH = ∠GHD = 50°

Step-by-step explanation:

Angles FGD and EDG are alternate interior angles, so are congruent. That means angle EDG is 100°. The angle sum theorem tells us ...

  ∠EDG = ∠EDH +∠HDG

  100° = 50° +∠HDG

  50° = ∠HDG

You can find the measure of ∠DHG a couple of different ways. It is an alternate interior angle congruent to ∠EDH, so is 50°. It is one of two remote interior angles that have  a sum equal to the exterior angle FGD, so is ...

  ∠DHG = ∠FGD -∠HDG = 100° -50° = 50°

So, angles DHG and HGD both have measures of 50°. When a triangle has two angles with the same measure, it is an isosceles triangle.

Answer:

The volume of the triangular prism is 5676.16 cm³

Step-by-step explanation:

The area of the triangular base A = bh/2 where b = base = 28 cm and h = height = 22.4 cm.

Now, the volume of the triangular prism, V = area of triangular base, A × height of prism, h'

V = Ah' where h = height of prism = 18.1 cm

So, V = bhh'/2

Substituting the values of the variables into the equation for V, we have

V = bhh'/2

V = 28 cm × 22.4 cm × 18.1 cm/2

V = 14 cm × 22.4 cm × 18.1 cm

V = 5676.16 cm³

So, the volume of the triangular prism is 5676.16 cm³

Answer:

5676.16 cm³

The answer is "$80".

Step-by-step explanation:

Please see the attached file for the whole question.

Yolanda's total pay y changes for each 'English is fun' sold x, i.e.

[tex]\frac{\delta y}{\delta x} = \frac{dy}{dx} \\\\y = 1900+80 x[/tex]

separating the above equation:

[tex]\frac{dy}{dx}= 80[/tex]

Therefore,

[tex]\frac{dy}{dx} = \$80[/tex]

For each 'English is enjoyable' sold x, the change in Yolanda total compensation y is [tex]\$80[/tex].
