The value of x is equal to 2. 2 times 2 will give you four. if you add one to the product, you get 5
X + (x+2) = 154
combine like terms
2x + 2 = 154
subtract 2
2x = 154
divide by 2
x = 76
so the two numbers are 76 and 78
34,669 to the nearest thousand is 35,000 because you look at the number to the right of that place value. less than 5, round down. 5 and up, round up.
-1 divided by x
1 - x
X - 1
Answer:
--- Two pink and One black
Step-by-step explanation:
Represent the pink skin with P and the black skin with B.
Since black skin is dominant to pink skin, there will be more occurrence of B than P
The punnet square for the breeding of the two pigs is then represented as:
Solving (a): Probability of Pink
In the above square, there is only 1 occurrence of P out of a possible of 4.
So, the probability is:
Solving (b): Probability that first and second are black
In the above square, there is only 3 occurrence of B out of a possible of 4.
So, the probability that both are black is:
Solving (c): Probability of two pink and 1 black
This is calculated as:
