In a genetics class, 6 students have GREEN eyes, 5 students have BLUE eyes, and 9 have HAZEL eyes. If a single student is picked

mixer [17]

EXPLANATION:

Given;

We are given that in a class there are the following groups of students;

$\begin{gathered} Green\text{ }eyes=6 \\ Blue\text{ }eyes=5 \\ Hazel\text{ }eyes=9 \end{gathered}$

Required;

We are required to calculate the probability that a student selected at random will have Green eyes OR Blue eyes.

Step-by-step solution;

To calculate the probability of an event, we shall use the following formula;

$P[Event]=\frac{Number\text{ }of\text{ }required\text{ }outcomes}{Number\text{ }of\text{ }all\text{ }possible\text{ }outcomes}$

To calculate the probability that a selected student will have green eyes;

$P[green]=\frac{6}{20}=\frac{3}{10}$

To calculate the probability that a selected student will have blue eyes;

$P[blue]=\frac{5}{20}=\frac{1}{4}$

The probability of event A or event B will be the addition of probabilities.

Therefore, the probability that a randomly selected student will have green or blue eyes will be;

$P[G]+P[B]=\frac{3}{10}+\frac{1}{4}$ $P[F]+P[B]=\frac{6}{20}+\frac{5}{20}=\frac{11}{20}$

Therefore,

ANSWER:

$P[G\text{ }orB]=\frac{11}{20}$

Which value of y forms the solution of the system defined by y = 11x + 1 and 11x + 12y = 12? (Select A - D from the screenshot)

alexandr1967 [171]

Answer:

y=1

Step-by-step explanation:

y = 11x + 1

11x + 12y = 12

Take the right side of the first equation, which is 11x + 1,

since y equals it, put it in parentheses like this (11x + 1)

and put it in place of y in the second equation.

The second equation is

11x + 12y = 12

Take out the y and put in (11x + 1) in place of the y:

11x + 12(11x + 1) = 12

Remove the parentheses by using the distributive principle:

11x + 132x + 12 = 12

Combine like terms on the left

143x + 12 = 12

Subtract 12 from both sides

143x = 0

Divide both sides by 143

x = 0

Now go back and get the very first equation:

y = 11x + 1

And substitute (0) for x:

y = 11(0) + 1

y = 0 + 1

y = 1
