The mean number of dogs per owner in your town is 1.63 dogs
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
To find the mean (average) number of dogs per owner in your town, we can use the formula:
Mean = (Sum of all values) / (Total number of values)
From the table, we can calculate the sum of all values by multiplying the number of dogs by their respective frequencies and adding them up:
(1 * 54) + (2 * 38) + (3 * 3) + (4 * 1) + (5 * 4) = 54 + 76 + 9 + 4 + 20 = 163
The total number of values (or dog owners) in your town is given as 100.
Plugging these values into the formula, we get:
Mean = 163 / 100
Mean = 1.63 (rounded to two decimal places)
Hence , the mean number of dogs per owner in your town is approximately 1.63 dogs

Use the original price and the markdown to find the retail price.
Original price: $80; Markdown: 20%
Answer:
$64
Step-by-step explanation:
20% of 80 = 16
$80 - $16 = $64
Answer:
$64
Step-by-step explanation:
1. Approach
Multiply the original price by the markdown, then subtract the result from the original price.
2.Find the amount by which the item was marked down
Multiply the original price by the percent by which it was marked down.
Original price * markdown
80 * 20%
*don't forget to convert the percent to a decimal by dividing the percent by 100
80 * 0.2
= 16
3. Find the new price
Subtract the amount by which the product was marked down from the original price;
original_price - markdown
80 - 16
= 64

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

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
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 pointsHope 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.
