Step-by-step explanation:

Madeline found that the experimental probability of her scoring from a
three-point line in a basketball game is 1/10 or 10%. Out of 20 shots from a
three-point line, about how many points could she predict she would make?

pls help

Answers

Answer:

6 points

Step-by-step explanation:

1/10=x/20cross multiply the x with the 10 and the 20 with the 1 so that you are now left with the fraction 10x/2010x divided by 20 will give you x=2to check and make sure this is still equivalent with the 10% of shots Madeline makes divide 2/20Since this is still 10 percent Madeline makes 2 out of every 20 shots Multiply those 2 shots by three points since it was from the three point line and we get 6 points

Hope that helps :)

Using the binomial distribution, it is found that she would be expected to make 6 points.

For each shot, there are only two possible outcomes, either she makes it, or she misses it. The probability of making a shot is independent of any other shot, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability, which has expected value given by:

[tex]E(X) = np[/tex]

In this problem:

She takes 20 shots, hence [tex]n = 20[/tex].She has a 10% probability of making each shot, hence [tex]p = 0.1[/tex]

The expected number of shots she makes is given by:

[tex]E(X) = np = 20(0.1) = 2[/tex]

Since each shot from the three-point line is worth 3 points, she is expected to make 2 x 3 = 6 points.

A. close to 3.2. B. close to 0.32 C. close to 320 or D. close to 32?

Answers

Answer:

8.1x^4 x 0.2 = 1.62x^4

Step-by-step explanation:

The estimated multiplication of 8.1 and 4.2 is close to 32.

What is a decimal?

A decimal is represented by a dot that separates the whole part and the fractional part of a number. Decimals can also be converted into fractions and vice versa.

Estimations are essential when we don't have a tool to calculate the exact value of something.

Given A multiplication of two decimal numbers 8.1 and 4.2.

Now 8.1 can be estimated as 8 and 4.2 can be estimated as 4 and we know 8 times 4 is 32 so, the multiplication of 8.1 and 4.2 is close to 32.

It takes Alia 7 minutes to run one mile m .Which equation can be used to show the relationship between Alia’s number of miles, ,and the total time of her run t

7t = m
7m = t
7+m = t
m-7 = t

Answers

7m=t is the correct answer and you can check by plugging 1 into m and you will get 7 for t.
the answer is 7m=t. this is because for every mile Alia runs it takes her 7 minutes. this means whatever the number of miles she runs is, you multiply that number by the 7 minutes it takes her to run each of those miles, which will give you t the total.
