Answer:
Step-by-step explanation:
To find the interquartile range, we first need to find the values of the first and third quartiles.
The median of the data set is 4. To find the first quartile, we take the median of the lower half of the data set:
1 1 3 3 | 4 4 5 7 7
^
First quartile = 3
To find the third quartile, we take the median of the upper half of the data set:
1 1 3 3 | 4 4 5 7 7
^
Third quartile = 7
The interquartile range is the difference between the third quartile and the first quartile:
7 - 3 = 4
Therefore, the interquartile range of the data set is 4.
A circular cookie cake is 113.04 square inches. What is the diameter of the cookie cake? Approximate using π = 3.14.
6 inches
12 inches
24 inches
36 inches
Answer:
6 inches
Step-by-step explanation:
a = [tex]\pi r^{2}[/tex]
113.04 = 3.14[tex]r^{2}[/tex] Divide both sides by 3.14
36 = [tex]r^{2}[/tex]
[tex]\sqrt{36}[/tex] = [tex]\sqrt{r^{2} }[/tex]
6 = r
Helping in the name of Jesus.
Answer:6 inches.
Step-by-step explanation: What is the radius of a circle with an area of 113.04 square inches?
Radius of the circle is of 3 inches.
Step-by-step explanation:
It is given that the area of the circle is 113.04,
Let the radius of the circle be of "a" units
=======================
From the properties of circle, we know : -
Area of circle = πr^2 , where r is the radius of the circle.
======================
Then, comparing the question with the identity :
= > πr^2 = 113.04 sq. inches
= > 3.14 x r^2 = 113.04 sq. inches
= > r^2 = 113.04 / 3.14 sq.inches
= > r^2 = 36 sq. inches
= > r = 6 inches
Hence,
r or radius of the circle is of 6 inches.
What mixed number represents 30/8
Answer:
3 6/8
Step-by-step explanation:
30÷8=3 6/8
8×3=24
30-24=6
Answer:
The mixed that represents 30/8 is --> 3 3/4
Step-by-step explanation:
Step 1: Find the whole number
We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.
30/8= 3.75 = 3
Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.
Step 2: Get the new numerator
To work this out we'll use the whole number we calculated in step one (3) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:
30 - (8 x 3) = 6
Step 3: Our mixed fraction
We've now simplified 30/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:
3 6/8
Step 4: Simplifying our fraction
In this case, our fraction (6/8) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 6 and 8 is 2.
We can now divide both the new numerator and the denominator by 2 to simplify this fraction down to its lowest terms.
6/2 = 3
8/2 = 4
When we put that together, we can see that our complete answer is:
3 3/4

Step-by-step explanation:
Polygon ABCD with vertices at A(1, 1), B(3, 1), C(3, 2), and D(1, 2) is dilated to create polygon A′B′C′D′ with vertices at A′(3, 3), B′(9, 3), C′(9, 6), and D′(3, 6). Determine the scale factor used to create the image.
3
2
one half
one third
To determine the scale factor used to dilate polygon ABCD to A′B′C′D′, we can compare the corresponding side lengths.
The distance between A(1, 1) and B(3, 1) is 2 units, and the distance between A′(3, 3) and B′(9, 3) is 6 units, so the horizontal side has been scaled by a factor of 6/2 = 3.
Similarly, the distance between A(1, 1) and D(1, 2) is 1 unit, and the distance between A′(3, 3) and D′(3, 6) is 3 units, so the vertical side has been scaled by a factor of 3/1 = 3.
Since both scaling factors are equal to 3, the overall scale factor used to dilate the polygon is 3. Answer: 3.

Step-by-step explanation:
You have to add 2 -2 2/6 and 5/6 that will get you -1 3/6. Then you have to find where it goes. If you would simplify the number you would get -1 1/2. This means the dot would be placed in the middle of 2 numbers. Since it is 1 and 1/2 you would need to place it between -1 and -2.

Marley surveyed the students in 7th grade to determine which type of social media they most commonly used. The data that Marley obtained is given in the table.
Type of Social Media Tweeter VidTok Headbook Picturegram
Number of Students 85 240 125 50
Which of the following circle graphs correctly represents the data in the table?
Choice A: a circle graph titled social media usage, with four sections labeled headbook 17 percent, picturegram 48 percent, tweeter 25 percent, and vidtok 10 percent
Choice B: a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Choice C: a circle graph titled social media usage, with four sections labeled tweeter 17 percent, vidtok 48 percent, headbook 25 percent, and picturegram 10 percent
Choice D: a circle graph titled social media usage, with four sections labeled picturegram 17 percent, tweeter 48 percent, vidtok 25 percent, and headbook 10 percent
Answer:
Choice C
Step-by-step explanation:
We first have to find the sum of the students.
85 + 240 + 125 + 50 = 500
Next, we have to find the percentage of each group of students for each group.
Users of Tweeter = 85 (17%)
Users of VidTok = 240 (48%)
Users of Headbook = 125 (25%)
Users of Picturegram = 50 (10%)
Therefore C is the answer

The tables represent the points earned in each game for a season by two football teams.
Saints
21 12 3
3 10 10
14 3 12
28 40 10
17 20 7
Cowboys
10 3 8
6 24 12
21 3 10
28 28 7
7 13 3
Which team had the best overall record for the season? Determine the best measure of center to compare and explain your answer.
Cowboys; they have a larger median value of 10 points
Saints; they have a larger median value of 12 points
Cowboys; they have a larger mean value of about 12.2 points
Saints; they have a larger mean value of about 14 points
Answer:
Saints; they have a larger mean value of about 14 points
Step-by-step explanation:
The mean is the best to use here since we are trying to determine the best overall record. Adding up all of the scores for the Saints will get you a total of 210, which then has to be divided by the number of numbers, which is 15. The Saints' mean is larger than the mean for the Cowboys, making your answer "Saints; they have a larger mean value of about 14 points".

ChoiceB: a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Choice C: a circle graph titled social media usage, with four sections labeled tweeter 17 percent, vidtok 48 percent, headbook 25 percent, and picturegram 10 percent
ChoiceD: a circle graph titled social media usage, with four sections labeled picturegram 17 percent, tweeter 48 percent, vidtok 25 percent, and headbook 10 percent
Answer:
The answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Step-by-step explanation:
By adding all the numbers you get 500, but you need to make it 100% so you divide the total number by five. To know what percent out of 100 you need to divide all of the variables by 5.
85 ÷ 5 = 172
40 ÷ 5 = 48
125 ÷ 5 = 25
50 ÷ 5 = 10
Thus the answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

What is the distance traveled by the tip of the second hand of a clock in 1 minute if the hand is 10.5 inches long? Leave your answer in terms of π.
Answer:
(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.
Step-by-step explanation:
The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.
If you have any questions ask me please! :)

Answer:
D. None of the above.
Step-by-step explanation:
To evaluate the expression when x = 6, we substitute 6 for x in the expression:
2 - 3(x - 5)
= 2 - 3(6 - 5)
= 2 - 3(1)
= 2 - 3
= -1
Therefore, the value of the expression when x = 6 is -1.
So, the answer is D. None of the above.
Answer: none of the above
Step-by-step explanation:
When x = 6 We substitute 6 for x in the expression:
2 - 3(x - 5)
2 - 3(6 - 5)
2 - 3(1)
2 - 3
= -1
PLEASE Show work and explain! Use proportion. Due in 12 hours.
Answer: 200/7
Step-by-step explanation:
This creates 3 similar right triangle
you would put similar parts on top and the similar parts on bottom of proportions.
ex.
[tex]\frac{hypotenuse}{short leg} = \frac{hypotenuse}{short leg}[/tex]
in your problem they gave the short legs and long legs of right triangel
The line that they share in middle of the triangle is the long leg for the triangle on right and it is also the short leg for triangle on left.
[tex]\frac{long leg}{short leg} =\frac{long leg}{short leg}[/tex]
[tex]\frac{x}{20} = \frac{20}{14}[/tex]
x=(400)/14 = 200/7
You could also make your proportion where
parts of 1 triangle = equivalent parts of the other
ex.
[tex]\frac{long leg from big triangle}{long leg from small triangle} = \frac{short leg big triangle}{short leg from small triangle}[/tex]
