Answer: 2/8
Step-by-step explanation:
The probability that the marbles are white or grey is 2/8 because since there is 2 marbles and the total is 8 so you have a probability of 25% to get white or gray
The initial value: 25, rate of change: -5 ⇒ answer C
Step-by-step explanation:
The table:
→ x : 1 : 3 : 5 : 7
→ y : 20 : 10 : 0 : -10
The linear relation between x and y is y = m x + b, where
- m is the rate of change
- b is the initial value
Let us use the table to find m and b
∵ , where
and are any two ordered pairs in the table
∵ = (1 , 20)
∵ = (3 , 10)
∴
∵ m is the rate of change
∴ The rate of change is -5
Substitute the value of m in the form of the linear relation
∴ y = -5 x + b
To find b substitute x and y in the equation by the coordinates of any points in the table, let us chose point (5 , 0)
∵ x = 5 and y = 0
∴ 0 = -5(5) + b
∴ 0 = -25 + b
- Add 25 to both sides
∴ 25 = b
∵ b represents the initial value
∴ The initial value is 25
The initial value: 25, rate of change: -5

Answer:
3(2+5)
Step-by-step explanation:
The common number that both 6 and 15 can be divided by is 3
3x2=6 and 3x5=15
P(of product of 2 dices) = 1/6 x 1/6 = 1/36
If we have 2 similar product then P(2 similar) = 2/36
If we have 3 similar product then P(3 similar) = 3/36
P(n similar) = n/36
P =0.2222 ====n/36 =0.2222 ≈ n=8 (right)
P =0.1667====n/36 = 0.1667 ≈ n=8 (right)
P = 0.7778====n/36 = 0.7778 ≈n = 28 WRONG ( with 2 dice we cannot get 28, since 28 = 4x7 or 7x4 and the max in one dye is 6)
