Answer:

probability of x is 0.22 correct to two decimal places

Step-by-step explanation:

step 1. use the poisson formula given as

p(x) = (λˣe∧-λ) ÷x! where λ is the mean and it called lambda,λ = 3, e is mathematical constant and it approximately = 2.7183, x is the chosen value which is equal to 2, Λ is raise to power, ! is factorial sign

p(x=2) =( 3² x 2.7183⁻³) ÷ 2! = 0.22

<h3>What is an equation?</h3>

A mathematical equation is the representation of a problem by the use of variables. Often times, an equation is formed from the factors that are in a problem.

We have to represented each of the books read with an algebraic term;

Let the number of mystery books be y

Let the number of sports books be x

Total number of books = 23

We know that;

x + y = 23

but y = 10

x = 23 - 10

x = 13 books

How do i solve this problem?<br>12 = 7 - 3x + 5x​
sleet_krkn [62]

Answer: 12=7−3x+5x

Step 1: Simplify both sides of the equation.

12=7−3x+5x

12=7+−3x+5x

12=(−3x+5x)+(7)(Combine Like Terms)

12=2x+7

12=2x+7

Step 2: Flip the equation.

2x+7=12

Step 3: Subtract 7 from both sides.

2x+7−7=12−7

2x=5

Step 4: Divide both sides by 2.

2x
