Answer:
Probability = 37.5%
Step-by-step explanation:
Prob (Race fast) = 10%, Prob (Slight Fast) = 40%, Prob (Normal Car) = 50%
Prob (Red Car) = 70% of race fast cars, & 45% of slight fast cars, & 30% of Normal cars, & = (70% x 10%) + (45% x 40%) + (30% x 50%) = 7% + 18% + 15% = 40%
Prob (Normal & Red Car) = 30% of 50% = 15%
Prob (Red car I Normal car) = Prob (Red & Normal Car I Normal Car) = 15% / 40% = 37.5%
When you are changing fractions to decimals you would want to make it like 5/10 =.5 just add 100ths the. Benchmarks are used for figuring how to solve it.
The value of x in the given equation [ √( 1 + (25/144) ) = 1 + (x/12) ] is 5.
<h3>What is an Equation?</h3>
An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.
Given that;
- √( 1 + (25/144) ) = 1 + (x/12)
First, we square both sides
√( 1 + (25/144) ) = 1 + (x/12)
(√( 1 + (25/144) ))² = (1 + (x/12))²
1 + (25/144) = 1 + ( x²/144)
Collect like terms
1 - 1 + (25/144) = ( x²/144)
25/144 = x²/144
We cross multiply
25 × 144 = x² × 144
Multiply each sides by 1/144
x² = 25
x = √25
x = 5
Therefore, the value of x in the given equation [ √( 1 + (25/144) ) = 1 + (x/12) ] is 5.
