MATHEMATICS MIDDLE SCHOOL

B) The game is used in a school to raise money for charity.Each player pays 20p to play the game.
To win a lollipop players have to score exactly 7.
Each lollipop costs the school 30p.
How much should the school expect to raise for charity
if 120 people play the game?

Answers

Answer 1
Answer:

Answer:

The answer is "1500p".

Step-by-step explanation:

The given probability is = 7. so, it is  (3)/(12) \ = (1)/(4)

It implies, that only if  120 people enjoy the sport, its school will gather

\ 120 * \ 20\ p = \ 2400 \ p

But, (1)/(4)  its side will survive = 30 people, as well as the school would have to invest \ 30 * \ 30p \ = \ 900p

for lollipops  So, the school will collect = 2400 - 900 = 1500p
Answer 2
Answer:

Answer:

£15

Step-by-step explanation:

First lets find out  how much the school earns when 120 play the game.

20p=£0.20 pounds

120 x 0.2= £24 that the school earns

Now to find how much the school needs to pay.

There are 3 out of 12 spaces on the possibility space that are 7's so 3/12 win which simplifies to 1/4.

1/4 of 120= 30 people who win the game

30p=£0.30 pounds

30 x 0.3= £9

What the school earns for people playing the game - money spent on lollipops= money raised for charity

£24-£9=£15

So the answer is £15. Hope this helps and is clear enough.

A function f(x) has x intercepts of -3 and -5. What is the constant term in the function? F(x)=x^2+8x+

Answers

Answer:

The constant term in the function is 5

Step-by-step explanation:

we have

f(x)=x^(2)+8x+b

where

b is the y-intercept or the constant term of the function

Remember that

The x-intercept is the value of x when the value of the function is equal to zero

so

For x=-3 ----> f(x)=0

For x=-5 ----> f(x)=0

substitute any of the intercepts in the function

For x=-3

0=(-3)^(2)+8(-3)+b

0=9-24+b

0=-15+b

b=15

f(x)=x^(2)+8x+15

Verify with the other intercept

For x=-5

0=(-5)^(2)+8(-5)+15

0=25-40+15

0=0 ---> is true

therefore

The constant term in the function is 5

The graph of the cube root parent function y =3^sqrt xtranslated to form f(x) shown on the graph.

Answers

The translated function is f(x)=∛(x+6)+1. Therefore, option A is the correct answer.

What is the translation?

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

The given function is y=∛x.

Draw the graph of the parent function y=∛x, as shown in the attached figure.

A few important point will be enough: (0, 0), (1, 1), (-1, -1), (8, 2), (-8, -2)

2. (0, 0) is an important point of the parent function, because as we go from the left to the right, the graph is concave up, than at (0, 0) it switches to concave down.

This point is called an inflection point, and in this function there is clearly only one.

3. The inflection point (0, 0) of the parent function  has been translated to (-6, 1), so all points have been shifted 6 units left and one unit up.

Therefore, option A is the correct answer.

Answer:

f(x) =  \sqrt[3]{x + 6} + 1

Step-by-step explanation:

Whenever addition or subtraction occurs within the cube root, it moves horizontally; the opposite is done for the translation, thus if it is addition, which in this case it is, instead of moving the positive direction, the function moves the negative direction.

As opposed to addition or subtraction outside of the cube root, it moves vertically, and in this case, it is translated exactly as stated. Here it states addition, thus the graph moves up in one unit.

The origin of the parent function is at ( 0, 0), in contrast, the origin of the function is at ( -6, 1 )

By using what we know, we can determine that the answer will be f(x) =  \sqrt[3]{x + 6} + 1 since we know that the inside of the cube root should be the opposite of the x value and the outside of the cube root should be the same.
