Answer:
The probability of getting two numbers whose sum is 10 is 25%.
Step-by-step explanation:
Given that a single die is rolled twice, and there are 36 equally-likely outcomes, to find the probability of getting two numbers whose sum is 10 the following calculation must be performed:
1 = +9
2 = +8
3 = +7
4 = +6
5 = +5
6 = +4
7 = +3
8 = +2
9 = +1
9/36 = 0.25
Therefore, the probability of getting two numbers whose sum is 10 is 25%.
We see that the differences are -9, -3, +3, and +9. Thus, we see that the function is symmetric about x=2 (I'm assuming the five values correspond to x=0, 1, 2, 3, 4) and increases at a rate similar to (x-2) squared. With that in mind, we classify this function as a parabola, as the standard form of a parabola (y=a(x-h)^2 + k) shows similar growth to this function.
Answer:
The midpoint is (9,6)
Step-by-step explanation:
The midpoint is just the average of the two end points.
x: (5 + 13)/2 = 18/2 = 9
y: (1 + 11)/2 = 12/2 = 6
The midpoint is (9,6)
Answer:
2x60, 4x30
Step-by-step explanation:
Given that the glee club has 120 cupcakes to sell.
These 120 cupcakes are to be arranged in a rectangle shape such that
there are even number of cakes lengthwise and even number of cakes breadthwise.
If l is the number of cakes along row, and m is the number of cakes along column, then we have both l and m as even.
Also lm=120
In other words, we must find 2 even factors of 120 l and m such that lm = 120
2x60 is one such pair
Next is 4x30.
There cannot be any other pair satisfying this condition.
Hence answer is 2x60 or 4x30
