Subtract 2n from -10n to get -12n
-12n
Answer:
0.2210
Step-by-step explanation:
If p = 0.04
then 1-p = 1 - 0.04 = 0.96
So we have the probability distribution value
as;
n C r * p^r * (1-p)^(n-r)
Thus;
64 C 3 * p^3 * (1-p)^(64-3)
= 64 C3 * 0.04^3 * 0.96^61
where 64 C 3 is 64 combination 3
= 41,664 * 0.04^3 * 0.96^61
= 0.2210

Hello,

Let's use the variable, x, to represent the unknown number.
We can represent the words, "the sum of a number and six, as : x + 6
The words, " 2 less than the sum", can be represented as: x + 6 - 2
The words, "the product of the number and three", can be written as: 3x
Now create an equation using "is equal to" to join the expressions:
x + 6 -2 = 3x
Now combine like terms and use inverse operations to solve for x:
x + 6 -2 = 3x
x + 4 = 3x
x + 4 - x = 3x - x
4 = 2x
4/2 = 2x/2
2 = x
The unknown number is 2
Answer:
16x
Step-by-step explanation:
Subtract the numbers: 9 - 5 = 4
Multiply the numbers: 
=16x
