Final answer:
Using the Empirical Rule and the given mean and standard deviation, we find that less than 1% of American women have shoe sizes no more than 3.89.
Explanation:
The student has asked about the percentage of American women who have shoe sizes no more than 3.89, given that the distribution of shoe sizes is bell-shaped, with a mean of 8.36 and a standard deviation of 1.49. Using the Empirical Rule, we know that around 68% of data falls within one standard deviation of the mean, approximately 95% within two standard deviations, and over 99% within three standard deviations.
To find the percentage in this case, we calculate the number of standard deviations 3.89 is from the mean. This number is (8.36 - 3.89) / 1.49 ≈ 3 standard deviations.
Since more than 99% of the distribution lies within three standard deviations from the mean, it is reasonable to infer that more than 99% of American women have shoe sizes larger than 3.89, which means less than 1% will have shoe sizes no more than 3.89.

A rose garden is circular. The diameter of the garden is 18 feet. Which is
closest to the total area of the garden? Use 3.14 for p.*
Answer: 254 ft
Step-by-step explanation:
Hi, to answer this we have to apply the formula for the area of a circle when we know the diameter.
Area of a circle (A)= (π/4) x D^2
Where D is the diameter
Replacing with the values given:
A = (π/4) x 18^2 = (3.14/4) x 324 =254.34 feet.
Feel free to ask for more if needed or if you did not understand something.
Final answer:
To calculate the area of a circular rose garden with a diameter of 18 feet using π as 3.14, the radius is found to be 9 feet. Using the formula πr², the area is calculated as 254.34 square feet, rounded to 254 square feet.
Explanation:
The question asks, “A rose garden is circular. The diameter of the garden is 18 feet. Which is closest to the total area of the garden? Use 3.14 for π.” To find the area of a circle, the formula is πr², where π (Pi) is approximately 3.14, and ‘r’ represents the radius of the circle. Given the diameter is 18 feet, the radius (half of the diameter) is 9 feet.
Plugging the values into the formula gives: A = πr² = 3.14 × (9 feet)². This equates to 3.14 × 81 feet² = 254.34 square feet. Therefore, the area of the rose garden is closest to 254 square feet.
What is true about traversals, no matter how they go through the parallel lines?
Answer:
Transversals? Transversals are different from traversals.
Step-by-step explanation:
Transversals always go through parallel lines. Okay, here are the rules. All pairs of alternate interior angles, alternate exterior angles, and corresponding angles are congruent pairs if the lines the transversal intersects are parallel, in which case each pair of consecutive interior angles are supplementary. That’s four rules right there.
Here are four more. If any of those pairs is congruent or supplementary, the lines the transversal intersects are parallel.
Vertical angles are always congruent, and any two angles that form a linear pair are supplementary. When you know all these rules, you can take the measure of any angle in the diagram and determine the measures of all the other angles as long as the lines intersected by the transversal are parallel.

a television and DVD player cost a total of 976. The cost of the television is three times the cost of the DVD player. Find the cost of each item
Answer:
DVD player- 244
Television- 732
Step-by-step explanation:
976÷4
(4 because you take the 3x bigger than the 1, so add it)
That gives you 244
so then the DVD player is 244
and for the TV you multiple 244 x 3 which gives you 732 and that is the price for the TV

The length of a rectangle is three times the width. What is the perimeter of the rectangle if the width is 17 inches?
51 inches
136 inches
204 inches
68 inches
Answer:
136 inches
Step-by-step explanation:
One side of the rectangle is 17 and the other side can be 3x because it's 3 times the width
3x=3(17)
= 51 inches which is the length and 17 inches is the width
2(51)+2(17) because you are finding the perimeter
And the answer is 136 inches
Answer:
136 inches
Step-by-step explanation:
First multiply 17 by 3 which equals 51. Then multiply 17 by 2 which equals 34 and 51 by 2 which equals 120. Then when you add those to sums you get 136 inches.

Jayden scored more than 2/3 the number of points Kenneth scored. If Jayden scored 24 points, which inequality solution represents , the number of points Kenneth could have scored?
Answer:The answer would be A. 1 1/5
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
Hope this helps!
Final answer:
To find the inequality for the number of points Kenneth could have scored if Jayden scored more than 2/3 of Kenneth's points when Jayden scored 24 points, we create the inequality 24 > (2/3)k and solve for k to find that the number of points that Kenneth scored is less than 36.
Explanation:
The student is asking how to represent an inequality where Jayden scored more than 2/3 of the points that Kenneth scored. If Jayden scored 24 points, we want to find the inequality solution for the number of points, k, that Kenneth could have scored.
To represent this inequality, we start by establishing that Jayden scored more than 2/3 of Kenneth's points, so we have:
24 > (2/3)k
Now we want to solve for k to find the range of values that Kenneth could have scored. Multiplying both sides of the inequality by 3/2 to isolate k, we get:
(3/2) * 24 > k
Which simplifies to:
36 > k
Therefore, the number of points Kenneth could have scored must be less than 36.

Which function rule represents the data in the table below? Input (x) 1 2 3 4 5 Output (y) 9 15 21 27 33 • y = 4 + 5x • y = 3 + 6x • y = 5 + 4x • y = 6 + 3x
By substituting the input values into each of the provided function rule options, it becomes clear that only the function rule y = 4 + 5x correctly represents the data in the given table.
Explanation:The question is asking which function rule represents the data in the given input and output table.
Let's test each option:
y = 4 + 5x: Replacing x by 1, we get y = 4+5*1 = 9 (It matches with the output table), Therefore this option seems to be the correct one, but let's check the other ones for confirmation. y = 3 + 6x: Replacing x by 1, we get y = 3+6*1 = 9 (But for x = 2, y becomes 15, which is not similar with the output table), therefore this isn't the correct function. y = 5 + 4x: Replacing x by 1, we get y = 5+4*1 = 9 (But again for x = 2, y becomes 13 which does not match with the output in the table), hence, not the correct function. y = 6 + 3x: Replacing x by 1, we get y = 6+3*1 = 9 (Once again, for x = 2, y becomes 12 which is not in the table), so it also isn't correct.
As a result, only the function rule y = 4 + 5x matches the pattern in the given table correctly.

Answer:
60% more.
Step-by-step explanation:
So you know 50 divided by 2 is 25, so add that to 50 to get 75. then you need to add ten more so you divide 50 by 5. so then 25+5 is 30 and 30 is 60% of 50 so it is marked up by 60% more.
Answer:
