Answer:
Answer: B. 24
Step-by-step explanation: 60 divided by 5 is 12. Twelve times two (the amount of girls) is 24. Twelve times 3 (the amount of boys) is 36. Since 24 + 36 = 60, there are 24 girls and 36 boys.
Answer:
of fabric.
Step-by-step explanation:
-The amount of fabric needed is equivalent to the area of the two gardens.
-We calculate the combined areas as:
Hence, 5811.95 sq meters of fabric will be needed to cover the area of both gardens.
I hope this helps. Have a great rest of your day!
Answer:
Interpreting the results:
a) At least 99.3% of the data lies between 12 standard deviations of the mean
b) The data lies between points 0 and 168
Step-by-step explanation:
The mean score on a driving exam for a group of driver's education students is 84 points, with a standard deviation of 5 points. Apply chebychev's theorem to the data using k= 12 interpret the results
Chebychev's theorem states that:
At least 1 - 1/k² data lies between k standard deviation of the mean
μ ± kσ
Where k is a positive number greater than 1
From the question above
μ = Mean = 84 points
σ = Standard deviation = 5 points
Hence: k = 12
We have:
1 - 1/12²
= 1 - 1/144
= 144 - 1/144
= 143/144
= 0.9930555556
Approximately = 99.3%
Interpreting these results means that At least 99.3% of the data lies between 12 standard deviations of the mean
Hence,
μ - kσ
84 - 12 × 7
= 84 - 84
= 0
μ + kσ
84 + 12 × 7
= 84 + 84
= 168
Hence, the data lies between points 0 and 168
Answer:
47.55 miles
Step-by-step explanation:
So for this problem you would just add the distance between the art store and the bank to the distance from the bank to the office supply store, which is 42 miles. Than you would use the Pythagorean Theorem so you would do and that should equal the square of our answers. is 1764 and is 497.29 and when you add them together you get 2,261.29. Now that we know the square of our answer we will just take the square root of it which is 47.55 miles and that is our final answer
