A number is chosen at random from a set

Mathematics
1 answer:
Arada [10]2 years ago
4 0

The probability that the chosen number selected satisfies the given condition is given below.

<h3>What is Probability?</h3>

Probability is the measure of the likeliness of an event to happen.

The probability has a range from 0 to 1, 0 denotes uncertainty, and 1 indicates certainty.

The set is numbers from 1 to 50.

The chosen number is not a perfect square,

The perfect square numbers are 1, 4, 9, 16, 25, 36, and 49.

The chosen number is not a perfect square, 50 - 7 = 43.

The probability that the chosen number is not a perfect square = 43/50

It is not a multiple of 4

Multiples of 4 are 4,8,12,16,20,24,28,32,36,40,44,48 are 12 numbers

The chosen number is not a multiple of 4 = 50 -12 = 38

The probability that the chosen number is not a multiple of 4 = 38/50

It is more than 45.

The number more than 45 is 5

The probability that the chosen number is more than 45 is,

=  5/50

= 1/10

It is not more than 45.

The number not more than 45 is 45.

The probability that the chosen number is not more than 45 is,

= 45/50

= 9/10

A and B are two similar shapes the area of shape A is 200cm2 calculate the area of shape B
barxatty [35]

Answer:

Area of shape B = 312.5 cm²

Step-by-step explanation:

Ratio of Area of A : Area of B = 12² : 15²

Given that area of A is 200 cm², let the area of shape B = x

Therefore:

200:x = 12²:15²

200/x = 144/225

Cross multiply

144x = 200*225

144x = 45,000

x = 45,000/144

x = 312.5 cm²

Area of shape B = 312.5 cm²

4x + 3y = 6<br> 3x + 5y = -1<br> Solve the simultaneous equations.<br><br> y= <br> z=
Kisachek [45]

Answer:

x=3, y= -2

Step-by-step explanation:

Multiplying :

(4x+3y =6)*-3

(3x+5y =-1)*4

-12x -9y= -18

12x+20y= -4

Add the equations

20y-9y = -4-18

11y = -22

y= -22/11 = -2

3x +5* -2= -1

3x -10 = -1

3x = 10-1

x= 9/3 =3

Doss [256]
(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
