Answer:

X is a discrete Random variable where X is the number of races Jockey can win.

Step-by-step explanation:

To find - A jockey will ride horses in 10 different races at a race track today.

The number of races that the jockey will win is what type of random variable ?

Proof -

Given that,

A jockey will ride horses in 10 different races at a race track today.

Let us assume that,

X is the number of races Jockey can win

So,

X can take value 0, 1, 2, 3, ......10

As,

It can take countable finite values

So,

X is a discrete Random variable

∴ we get

X is a discrete Random variable where X is the number of races Jockey can win.

Answer:

G. 60 m²

Step-by-step explanation:

The lawn is in the shape of a trapezium.

The area of a trapezium can be found using the equation  0.5*h*(a+b), where h is the height and a and b are the top and bottom of the shape.

Area = 0.5*h*(a+b)

= 0.5*4*(12+18)

= 60 m²

Answer:

56

Step-by-step explanation:

Angles w and 124 are linear pair angles,

w + 124 = 180

w = 180 - 124

w = 56

Answer: Best anwser 5.5

Step-by-step explanation:

Answer:

Solution given:

9x-4=8+7x[Vertically opposite angle]

9x-7x=8+4

2x=12

x=12/2

x=6

:.8+7x=8+7×6=50°

Answer:

50

Step-by-step explanation:

9x - 4 = 8 + 7x

x = 6

Therefore, 8 + (7 *6) = 50

The measure of the angle is 50

Answer:

[tex]B =(3.3,1.7)[/tex]

Step-by-step explanation:

Given

[tex]A(x_1,y_1) = (-4,-2)[/tex]

[tex]P(x,y) = (2,1)[/tex]

[tex]m : n = 9 : 2[/tex]

Required

The coordinates of [tex]B(x_2,y_2)[/tex]

The line segment from ratio is calculated as:

[tex](x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]

Substitute: A, P, m and n

[tex](2,1) = (\frac{9 * x_2 + 2*-4}{9+2},\frac{9*y_2 +2 *-2}{9+2})[/tex]

[tex](2,1) = (\frac{9x_2 -8}{11},\frac{9y_2 -4}{11})[/tex]

Multiply through by 11

[tex](22,11) = (9x_2 -8,9y_2 -4)[/tex]

By comparison:

[tex]9x_2 - 8 = 22[/tex]

[tex]9y_2 - 4 = 11[/tex]

So, we have:

[tex]9x_2 - 8 = 22[/tex]

[tex]9x_2 = 22 +8[/tex]

[tex]9x_2 = 30[/tex]

Solve for x2

[tex]x_2 = 30/9[/tex]

[tex]x_2 = 3.3[/tex]

[tex]9y_2 - 4 = 11[/tex]

[tex]9y_2 = 11+4[/tex]

[tex]9y_2 = 15[/tex]

Solve for y2

[tex]y_2 =15/9[/tex]

[tex]y_2 =1.7[/tex]

So, the coordinates of B is:

[tex]B =(3.3,1.7)[/tex]

500 ml water 4 times a day = 500x4= 2000 ml water per day

there are 7 days in a week so,

2000 x 7 = 14000 ml

Answer:

correct its d

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

3=t-12

12+3=t

15=t

c is the answer

Answer:

<1= 62

•it is 62 because it is an alternate interior angle which is congruent

<2= 83

• when you add the given angles 62 and 35 you get 97 and a triangle is 180 so you subtract 97 from 180

<3=35

• it is 35 because it is an alternate interior angle which is congruent

Step-by-step explanation:

62+35= 97

180-97= 83

Using the normal distribution, we have that:

a) 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.

b) 34.46% of pizzas were prepared and delivered in less than 18 minutes.

c) 2.28% of the pizza will be free.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

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

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 20, \sigma = 5[/tex]

For item a, the probability is the p-value of Z when X = 25 subtracted by the p-value of Z when X = 20, hence:

X = 25:

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

[tex]Z = \frac{25 - 20}{5}[/tex]

Z = 1

Z = 1 has a p-value of 0.8413.

X = 20:

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

[tex]Z = \frac{20 - 20}{5}[/tex]

Z = 0

Z = 0 has a p-value of 0.5.

0.8413 - 0.5 = 0.3413.

Hence 34.13% of pizzas were prepared and delivered between 20 and 25 minutes.

For item b, the probability is the p-value of Z when X = 18, hence:

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

[tex]Z = \frac{18 - 20}{5}[/tex]

Z = -0.4

Z = -0.4 has a p-value of 0.3446.

34.46% of pizzas were prepared and delivered in less than 18 minutes.

For item c, the proportion is one subtracted by the p-value of Z when X = 30, hence:

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

[tex]Z = \frac{30 - 20}{5}[/tex]

Z = 2

Z = 2 has a p-value of 0.9772.

1 - 0.9772 = 0.0228, hence 2.28% of the pizza will be free.
