Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

ANSWER; x = 131/333
Answer:
\(x=\dfrac{131}{333}\)
Step-by-step explanation:
Assign the decimal to a variable:
Let \(x=0.\overline{393}\)
Multiply both sides by 1000:
\(\implies x \cdot 1000=0.\overline{393} \cdot 1000\)
\(\implies 1000x=393.\overline{393}\)
Subtract the first equation from the second to eliminate the part after the decimal:
\(\begin{array}{r r c r}& 1000x & = & 393.\overline{393} \\\\- & x & = & 0.\overline{393} \\\\\cline{2-4} \\& 999x & = & 393 \\\end{array}\)
Divide both sides by 999:
\(\implies \dfrac{999x}{999}=\dfrac{393}{999}\)
\(\implies x=\dfrac{393}{999}\)
Reduce the fraction:
\(\implies x=\dfrac{393 \div 3}{999 \div 3}\)
\(\implies x=\dfrac{131}{333}\)

Describe how the data is dispersed in a box plot with the following data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
AND PLEASE ACTUALLY EXPLAIN/DESCRIBE!
In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.
1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

Michael is baking cookies. His cookie recipe calls for 3/4 cups sugar and makes 24 cookies. If he wants to scale the recipe to make exactly 18 cookies, how many cups of sugar will he need? Express your answer as a mixed number.
\(\begin{array}{ccll} \stackrel{cups}{sugar}&cookies\\ \cline{1-2} \frac{3}{4}&24\\[1em] x&18 \end{array}\implies \cfrac{ ~~ \frac{3}{4} ~~ }{x}~~ = ~~\cfrac{24}{18}\implies \cfrac{ ~~ \frac{3}{4} ~~ }{\frac{x}{1}}~~ = ~~\cfrac{4}{3}\implies \cfrac{3}{4}\cdot \cfrac{1}{x}=\cfrac{4}{3} \\\\\\ \cfrac{3}{4x}=\cfrac{4}{3}\implies 9=16x\implies \cfrac{9}{16}=x\)
now, the fraction is not an improper one, thus we can't quite put it in a mixed format, unless you count 0 as its whole, then I guess we can say is \(0\frac{9}{16}=x\)

∠A and ∠B are vertical angles. If m ∠A=(4x+6)° and m ∠B=(2x+18)°, then find the value of x.
Answer:
x = 6
Step-by-step explanation:
You want the value of x if the expressions (4x+6)° and (2x+18)° represent the measures of vertical angles.
Vertical anglesVertical angles have the same measure, so these expressions are equal to each other:
4x +6 = 2x +18
2x = 12 . . . . . . . . . . subtract 2x+6 from both sides
x = 6 . . . . . . . . divide by 2

The angles are each 30°.

Step-by-step explanation:
Profit, P(r), is the difference between revenue, R(r), and cost, C(r), so P(r) = R(r) - C(r) Which expression represents P(r), if R(r) - 2r^4 - 3r^3 + 2r - 1 and C(r) = r^4 - r^2 + 2r + 3?
The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Profit is the difference between revenue and cost. Given that:
R(r) = 2r⁴ - 3r³ + 2r - 1 and C(r) = r⁴ - r² + 2r + 3
P(r) = R(r) - C(r)
P(r) = (2r⁴ - 3r³ + 2r - 1) - (r⁴ - r² + 2r + 3) = r⁴ - 3r³ - r² - 4
The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4

885 = 3.14 ×r² × 11.7
what is r ?
Answer:
4.89897948557
if you rounded it, it would be 4.90, or 4.9
Step-by-step explanation:
First, I solved 3.14 x 11.7. This gave me 36.738.
Next, I did 885 divided by 36.738. This gave me a long list of numbers, but the whole was 24. (24.0894986117916…)
I rounded that number to 24.
Now, I found the square root of 24. Square root is basically a number that is multiplied by itself to get a number. For example, the square root of 9 is 3, because three times three is nine.
Anyways, the square root of 24 came out to be 4.89897948557. So, I rounded and got 4.9.

the measure of angle ABD is 134 degrees. what is the measure of x? What angle relationship is needed to be solved?
Explanation
The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.
(angle ABD) + (angle DBC) = 180
(134) + (2x) = 180
2x = 180-134
2x = 46
x = 46/2
x = 23
Answer: x=23 and the angle relation used was supplementary angles
Step-by-step explanation:
first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

9. Find the value of x. Using that value, what is the
measurement of ZUTQ?
thank you <3
Answer:
92°
Step-by-step explanation:
We know that \(\overline{QV}\) is a straight line which means that we know that ∠QTU + ∠VTU = 180
11x+4+∠VTU = 180
∠VTU = 180-11x-4
∠VTU = 176-11x
Then, using the triangle inequality, we know that ∠VTU+∠TUV+∠UVT = 180
3x+14+54+176-11x=180
-8x+244=180
-8x = -64
x=8
Now we can substitute and solve for ∠UTQ
11(8)+4 = 88+4 = 92°
Answer: 92°
