For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
Doing the multiplication we have:
From here, we clear the value of x.
We have then:
Therefore, we have:
Answer:
7 times 1/7 equals 1
First let's get rid of the parenthesis:
12 - 4x + 3x = 4 + 10 + 2x
Now group the x's on the left and the numbers on the right
-4x + 3x - 2x = 4 + 10 - 12
...and simplify
-3x = 2
divide by -3 to isolate x
x = -2/3
Answer: 0.243.
Step-by-step explanation:
The probability in this case is approcimated by the probability distribution formula for random variables. This formula is denoted as:
P(X=r) = nCr * p^r * q^n-r
Where n = selected number to be sampled and in this case, n= 3
r = varied number of sample and in this case, r=1
P = probability of success and in this case p = 0.10
q = 1-p=1-0.1 = 0.9
P(X=1) = 3C1 × 0.1¹ × 0.9²
P(X=1) = 0.243.
Answer:
$81
Step-by-step explanation:
Hello, this is the logic:
If $63 ---> 35%
$X -----> 100%
then,
X = [(100)*(63)]/35
X = $18
Then his total money was 63 + 18 = $81
Best regards
