Based on the tallies and frequencies for the first and last intervals, how many intervals of what length did Jamie use?

4 intervals of 1000 feet
c.
6 intervals of 500 feet
b.
5 intervals of 1000 feet
d.
7 intervals of 500 feet
Answers
Answer:
D. 7 intervals of 500 feet
Step-by-step explanation:
Got it right
Jamie used 5 intervals of 1000 feet as per the given data. The correct option is b.
What are tallies and frequencies?A tally chart is a straightforward method of recording and counting frequencies. Each occurrence is represented by a tally mark, and every fifth tally is drawn diagonally to form a five-pointed star.
The first interval has a frequency of 7, which corresponds to the first 7 data points in the list:
1010
1470
1600
2000
2800
1053
1495
The last interval has a frequency of 2, which corresponds to the last 2 data points in the list:
2310
4260
Since there are 25 data points in total, and the first 7 and last 2 have been accounted for, that leaves 16 data points for the remaining intervals.
If Jamie used 1000-foot intervals, each interval would cover a 1000-foot range. The remaining data points range from 1200 to 4200 feet, so they are divided into 1000-2000, 2000-3000, and 3000-4000 foot intervals.
If Jamie used 500-foot intervals, each interval would cover a 500-foot range.
Thus, because the remaining data points range from 1200 to 4200 feet, they are divided into 1000-1499, 1500-1999, 2000-2499, 2500-2999, 3000-3499, 3500-3999, and 4000-4499 foot intervals.

Find the mean age for CLUB A :
Answers
Answer:

Step-by-step explanation:
You can find the mean for club A by adding up every number in the set and then dividing by the amount of numbers in the data set:
So first we add up 42+38+40+34+37+46+38+45
Which = 320
Now we divide that number by 8 because there are 8 numbers in the data set (all the numbers we added up):
320/8=40
So now we know that the mean age is 40!
Hope this helps :)!

Read the information below and answer the questions. Suppose a researcher wants to learn more about the mean attention span of individuals in some hypothetical population. The researcher cites that the attention span (the time in minutes attending to some task) in this population is normally distributed with the following characteristics: 20 36 . Based on the parameters given in this example, answer the following questions: 1. What is the population mean (μ)?
Answers
Answer:
The population mean (μ) = 26.
Step-by-step explanation:
a) Data and Calculations:
The population characteristics = 20 and 36
Total population of interest = 56 (20 + 36)
Number of groups in the population = 2
Therefore, the population mean (μ) = 56/2 = 28
b) Based on the parameters given in this example, the population mean equals the average of the group characteristic (attention span of individuals in minutes) or item of interest. The population mean is calculated by adding the values of the group characteristic and then dividing the result by the number of values.

a circle has a diameter of 5 inches. What is the area of the circle in terms of pi
Answers
Answer:
The area of the circle is [tex]\mathbf{6.25\pi}[/tex]
Step-by-step explanation:
Area of a Circle
A circle of radius r has an area calculated by the following formula:
[tex]A=\pi r^2[/tex]
The diameter of a circle is twice the radius, thus the radius is half the value of the diameter.
A given circle has a diameter of 5 inches.
The radius of this circle is r = 5/2 = 2.5 inches.
Thus, the area is calculated below:
[tex]A=\pi 2.5^2 = 6.25\pi[/tex]
The area of the circle is [tex]\mathbf{6.25\pi}[/tex]

B is the best example where substitution is the best method since you already have one where y = something and you can plug -2/7x + 11 into the bottom equation for y and solve it that way. A and C make you get x or y by itself first first substitution would work and D already gives you the answers. B is the best since its already set in that format.

A seamstress needs to cut 15-inch pieces of ribbon from a roll of ribbon that is
9 feet in length. What is the greatest number of 15-inch pieces the seamstress
can cut from 5 of these rolls of ribbon?
Show your work.
Answers
Answer:
The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35
Step-by-step explanation:
Given
Total length of one roll of ribbon = 9 feet
As the pieces have to be cut into inches, we will convert the measurement in feet to inches
As there are 12 inches in one feet, 9 feet will be equal to:
9*12 = 108 inches
Now first of all, we have to see how many 15 inches pieces can be cut from one role
So,
[tex]=\frac{Length\ of\ roll}{Length\ of\ piece}\\=\frac{108}{15}\\=7.2[/tex]
So the seamstress can cut 7 15-inch long pieces from a roll.
Now given that he has to cut from 5 rolls, the total number of 15-inch pieces will be:
[tex]= 5 * 7 =35[/tex]
Hence,
The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35

Every quadratic function either has a maximum or minimum value.
A. False, became a quadratic equation does not have a maximum value.
B. True, because the graph of quadratic function is a curve that is either increasing or decreasing.
C. True, because the graph of a quadratic function is a parabola that either opens downwards or upwards.
D. False, because a quadratic function does not have a minimum value.
Answers
Answer:
C
Step-by-step explanation:
If the parabola opens upward, it has a minimum.
If it opens downwards, it has a maximum.
Every quadratic function either has a maximum or minimum value is true, because the graph of a quadratic function is a parabola that either opens downwards or upwards.
What is Quadratic Function?A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two. Since the highest degree term in a quadratic function is of the second degree, therefore it is also called the polynomial of degree 2.
What are properties of quadratic functions?Three properties that are universal to all quadratic functions:
1) The graph of a quadratic function is always a parabola that either opens upward or downward (end behavior).
2) The domain of a quadratic function is all real numbers.
3) The vertex is the lowest point when the parabola opens upwards; while the vertex is the highest point when the parabola opens downwards.
According to the question
Every quadratic function either has a maximum or minimum value.
As per the properties of Quadratic Function
This statement is true as
i> the graph of a quadratic function is a parabola
ii> The vertex is the lowest point when the parabola opens upwards or the vertex is the highest point when the parabola opens downwards.
Hence, Every quadratic function either has a maximum or minimum value is true, because the graph of a quadratic function is a parabola that either opens downwards or upwards.

POSSIBLE POINTS : 13.33 If a wall has a diagonal beam holding it in place that is 12ft long and the height of the wall is 8ft and the base of the beam on the floor is 7ft from the wall is the wall perpendicular?
Answers
Answer:
Step-by-step explanation:
If the wall is perpendicular, then that means that this is a right triangle. We can find out if it is by using Pythagorean's Theorem and filling in the values for the sides. If the statement is true, then the triangle is right and the wall is perpendicular to the base.
[tex]a^2+b^2=c^2[/tex] and filling in:

[tex]49+64=144[/tex] Is this true?
113 = 144
Definitely not true. So this is not a right triangle and the wall is not perpendicular to the floor.

Scientific notation is a tool that is used frequently in science, including astronomy, chemistry, biology, and more. In this activity, imagine that you are a student intern at NASA and are researching information about travel within our solar system. You will complete a series of tasks using what you know about scientific notation and what you discover about our solar system to calculate distances that astronauts may use for their next trip to space.
Part 1
Using technology or other resources, research the average distance that each planet is from the sun (in kilometers). Once you have found the distance, create a chart showing each planet's distance from the sun. The sun itself will not receive a label since it is your starting point. For example, Mercury is located an average of 57,909,000 km from the sun, so on the chart, Mercury would be labeled with a distance of 57,909,000. Use the example of the chart below to help you get started:
