Answer:

£289.20

Step-by-step explanation:

13:2 = x:16 or 13/2 = x/16

cross multiply: 208 = 2x

simplify: x = 104

16 blue tiles x £2.80 each = £44.80

104 white tiles x £2.35 each = £244.40

44.80 + 244.40 = £289.20

The sample at option B, {0, 2} is not a part of the sample space of a spinner when spun two times.

<h3>What is a sample space?</h3>

The set consists of all the possible outcomes of an event called sample points, which is said to be a sample space.

<h3>Calculation:</h3>

It is given that,

a spinner has 5 sections of equal area and each section is numbered from 1 to 5.

If the spinner is spun two times, then the possible outcomes are 25. They are:

{(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5)}

So, from the given options, the sample {0, 2} is not possible since there is no such a section on the spinner named 0.

Use the system of equations to answer the questions. 2x + 3y = 3, y = 8 - 3x. The value of y from the second equation is substit
Fittoniya [83]

Answer:

x=3 y=-1

Step-by-step explanation:

To get the value of x you need to put in the second equation which is y=8-3x as the y value for the first equation which is 2x+3y=3 making it

2x+3(8-3x)=3

2x+24-9x =3

24-7x =3

-7x=-21

Multiplying both sides by -7

x= 3

After getting an x value you substitute it in the equation in order to find your y value which is

2x+3y=3

2(3)+3y=3

3y=-3

Multiplying both sides by 3

y= <u>-3</u>

3

y=-1
