Answer:
To find the mean of a data set you have add all the values together and divide by the number of values in the set. The result is your mean
Step-by-step explanation:
Such as finding the mean of 1, 2, 4, 7, 9 as an example
Adding those numbers together you get 23. You then divide 23 by 5, given that there are 5 values above. 23/5 is 4.6. The mean would be 4.6
2/5=0.4=40%
3/5=0.6=60%
40% chance of a car
60% chance of consolation prizes

Answer:
(d) (-2, 6)
Step-by-step explanation:
We can rewrite the function using vertex form.
f(x) = (x^2 +4x) +10
f(x) = (x^2 +4x +4) +10 -4 . . . . . . . add and subtract (4/2)^2
f(x) = (x +2)^2 +6
Compare to vertex form:
f(x) = (x -h)^2 +k
we see that (h, k) = (-2, 6) . . . . the vertex

<em>Additional comment</em>
The value added and subtracted is the square of half the x-coefficient. Inside parentheses, that value "completes the square". Outside parentheses, that value ensures the overall function remains unchanged.
I think the answer is 35.28 square units. Because triangle ABC is 1/2 of triangle XYZ, the height must be halved. So, 3.36/2 is 1.68. Now, you times 42 by 1.68 to get 70.56. Then, divide that by 2 to get 35.28
25 - (3*3) - (3*5)
25 - 9 - 15
=1
Yes it is enough, and will have balance of 1g
