Answer:
£10 pounds
Step-by-step explanation:
135+70+35 = 240 pounds between all 3
3:2:1 ratio means 6x represents all of them
6x=240
x=£40 each 1
3(40) = £120 Sarah
2(40) = £80 Gemma
1(40+ = £40 Beth
Gemma received 10 pounds.
The equation of the red graphed function is: g(x) = 1 - x².
<h3>How to Find the Equation of a Graphed Function?</h3>
Given the graph shown in the attachment below, the graphed function heads downwards, and the x - axis is intercepted at ( 1, 0 ) and (-1,0).
Thus, the x-intercepts, which is the zeros of the function, are: 1 and -1.
So, g(x) = (x + 1)(x -1)
Expand:
g(x) = 1 - x²
The equation of the red graph is: g(x) = 1 - x².

The right answer is Option B and Option E.
Step-by-step explanation:
Given value is;
2% of 90.
Percent can also be written fraction form, therefore, we can write it as;

If we divide the 2 the by 100, then it would become,

Therefore,
and 0.02*90 have same value as 2% of 90.
The right answer is Option B and Option E.

The mean is the "average", where all the numbers given are added together and then divided by however many numbers there are.
Answer:
Final answer is
.
Step-by-step explanation:
Given that two 6-sided number cubes are rolled. Now we need to find about what is the possibility of rolling a sum of 8.
From the sample space, you can see that there are total 36 possible outcomes.
out of those outcomes, there are only 5 outcomes that has sum = 8
which are {(2,6), (3,5), (4,4), (5,3), (6,2)}.
Hence probability of rolling a sum of 8
.
Hence final answer is
.
