Jada, Diego, and Elena each use the same spinner that has four (not necessarily equal sized) sections marked A, B, C, and D.

Jada says, "The probability of spinning B is 0.3 because I spun 10 times, and it landed on B 3 times."

Diego says, "The probability of spinning B is 20% because I spun 5 times, and it landed on B once."

Elena says, "The probability of spinning B is 27 because I spun 7 times, and it landed on B twice."

Based on their methods, which probability estimate do you think is the most accurate?

Step-by-step explanation:

A truck can be rented from Company A for ​$90 a day plus ​$0.30 per mile. Company B charges ​$40 a day plus ​$0.40 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
At _____ nothing ​miles, the rental costs are the same from either company.

Answers

Answer

The answer is 500 miles

Step-by-step explanation:

So, 500 x 0.40 is equal to $200. And if we add the $40 a day fee it's now $240.

And the other company charges $0.30 a mile. So that equation is:

500 x 0.30 = $150 plus the $90 fee is $240.

The sum of the measures of two angles is 183.6°. One angle has a measure of 54°. What is m , the measure in degrees of the second angle?

Answers

Answer:

129.6

Step-by-step explanation:

We know that the total of both angles is 183.6. Then, we know another angle which is 54 degrees. With this, we can make an equation. Let's say x is the second angle:

[tex]x+54=183.6\\\\\text{Subtract 54 from both sides}\\x=183.6-54\\x=129.6\\[/tex]

Lamar has been saving $6 each week. Today he spent $90 of the savings, and he now has $48 left. For how many weeks has he been saving?

Answers

I believe the answer is 23, 90+48 divided by 6= 23
So it’s simple. We know he gets $6 every week. Spent $90 and has $48 left. So 90+48=138. That’s how much he had saved. Now divide it by 6 to find out how many weeks he’s been saving to gg $138. 138/6=23.
Lamar has been saving for 23 weeks.

Charlie is going to watch a movie in his collection. He has 3 action movies, 4 comedies, and 5 dramas. He will randomly select one movie. What is the probability that the movie he selects is not a comedy?

Answers

Answer: 5

Step-by-step explanation:

I don’t know if your teacher wants it in fraction form but the answer in fraction form would be 8/12. Because it’s asking for the probability of selecting a non-comedy movie, we only focus on the action and drama movies. We add them up, that gives us 8, and put it over the total number of movies (12). That’s how I got 8/12. If you have any questions comment on my answer so I can see it. Have a nice day!
