Maria will spin the arrow on the spinner 2 times. What is the probability that the arrow will stop on the same letter twice? A. 1/9 B. 2/9 C. 1/3 D. 5/9

Answer:

probability that the arrow will stop on the same letter twice = \frac{1}{3} (c).

Step-by-step explanation:

Given : Maria will spin the arrow on the spinner 2 times.

To find : What is the probability that the arrow will stop on the same letter twice.

Solution : We have given a spinner that spin twice and stop on the same letter.

Formula for probability = \frac{number \ of \ favorable\ outcome}{Total \number\ of \possible \outcome}.

Here, total part of spinner = 3 and it spin two times

So, total possible outcome = 6.  Arrow ston on same letter twice( favorable outcome) =2.

Plugging the values in formula :

Probability =  \frac{2}{6}.

Probability =  \frac{1}{3}.

Therefore,  probability that the arrow will stop on the same letter twice = \frac{1}{3} (c).

A student spent 3/4 of an hour reading an article and 2 1/6 hours writing an essay about what he read. how much time did the student spend on the assignment?

So, we need to add 3/4 + 2 1/6.

First, let's find a common denominator.

12 is one.

4 x 3 = 12  3 x 3 = 9        6 x 2 = 12   1 x 2 = 2     2/12 & 9/12 = 11/12

2 + 0 = 2.  2 + 11/12 = 2 11/12.

2 11/12 is your answer.

If you have any questions, comment below.

Glad I could help, and good luck!

PLEASE HELP FAST!!!!!!!!!!!!!!!!!!!!!1 A car license plate is made up of 7 letters or numbers, where the numbers are whole numbers 0–9. Suppose that a license plate is randomly generated, one character at a time. What is the probability that the first character is a number? Enter your answer as a decimal rounded to the nearest hundredth in the box

It is .277
because there are 26 letters in the alphabet, and 10 numbers given (0-9)
add both amount of characters: 26+10=36
then put a number of numbers over the total amount of characters: 10/36
now divide 10 by 36
and you will get .277777, but since you said by the nearest hundredth, estimate and get

Yves bought 420 tropical fish for a museum display. He bought 6 times as many parrotfish as angelfish. How many of each type of fish did he buy? Which is a system of equations to model the problem if x represents the number of angelfish Yves bought and y represents the number of parrotfish he bought? x + y = 6 y = 420x x + 6y = 420 y = 6x x – y = 420 y = 6x x + y = 420 y = 6x

Answer: D is the right equation.


Step-by-step explanation:

Yves total number of fish is 420

x and y represent the number of fish

^ x + y = 420  (we know the equation is an addition form because of the key word  ''and'')

Then it says ''he bought 6 times as many parrot-fish (y) AS angelfish (x)

^ y = 6x

If you role a number cube 12 times about how many times do you expect to role a number less than 5

I guess this cube is a dye & it has six faces numbered from 1 to 6.

If so the expected value is the probability x number of times:


P(getting 1 or 2 or 3 or 4) = 4/6 = 2/3

The number of times = 10, hence the expected value is 12x(2/3) = 8 times
