Answer:
2.5
Step-by-step explanation:
The equation will have infinite solutions when it is a tautology--when both sides say exactly the same thing.
Eliminate parentheses, match coefficients, and solve for b.
ax +ab = 4x +10
a = 4 . . . . . . coefficient of x
ab = 10 . . . . constant
Since we know a, we can find b:
4b = 10
b = 10/4 . . . . . . . divide by 4
b = 5/2 = 2.5 . . .express in your favorite form
The value of for x = 5 is 0.06
<h3>How to solve the probability?</h3>
The expression is given as:
This means that:
n = 10
p = 0.75
The probability is then calculated as
This gives
Evaluate the combination expression
Evaluate
P(5)= 0.06
Hence, the value of for x = 5 is 0.06
