\(\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100\)
To find what percent of 200 is 120, substitute the values into the percentage formula:
\(\begin{aligned}\implies \sf Percentage & = \dfrac{120}{200} \times 100\\\\&=\dfrac{120 \times 100}{200}\\\\&=\dfrac{12000}{200}\\\\&=\dfrac{120}{2}\\\\&=60\%\end{aligned}\)
Therefore, 120 is 60% of 200.

Answers
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

Answer: 59.3 feet

Explanation:
Since you are finding the depth your formula will look like this
11.77= 2.8 x 1.8 x d
(d stands for depth since we don’t know the value)
To solve it you multiply 2.8 and 1.8 which equals 5.04
So now your equation looks like this
11.77= 5.04 x d
Next you divide 11.77 by 5.04 and get
2.33531746
This rounds to 2 so the answer is 2.

Let’s mark the Triangle Points as Point A, Point B, Point C.
Point A = 1x°
Point B = 2x°
Point C = 3x°
We know that the Angle Sum of a Triangle is equal to 180°.
So, Point A + Point B +Point C = 180°
= 1x° + 2x° + 3x° = 180°
= (1 + 2 + 3)x° = 180°

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answers
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.

What is the appropriate measure of variability for the data shown, and what is its value?
The IQR is the best measure of variability, and it equals 32.
The range is the best measure of variability, and it equals 11.
The IQR is the best measure of variability, and it equals 11.
The range is the best measure of variability, and it equals 32.
Answers
To determine the appropriate measure of variability for the given data, we first need to determine the range of the data, which is the difference between the largest and smallest values. The largest value in the data set is 49, and the smallest value is 17. Therefore:
Range = Largest value - Smallest value = 49 - 17 = 32
The range tells us the spread of the entire data set, but it can be heavily influenced by outliers. To get a measure of variability that is resistant to outliers, we can use the interquartile range (IQR), which measures the spread of the middle 50% of the data. To calculate the IQR, we need to find the first quartile (Q1) and the third quartile (Q3) of the data.
From the stem-and-leaf plot, we can see that the smallest value is 17 and the largest value is 49. To find Q1 and Q3, we need to identify the median of the lower half of the data and the median of the upper half of the data, respectively. The stem-and-leaf plot shows:
1 7, 9
2 1, 5, 9
3 0, 1, 2
4 6, 9
The median of the entire data set is the value that splits the data into two equal halves. Since there are 20 values in the data set, the median is theaverage of the 10th and 11th values when the data is sorted in ascending order. The 10th and 11th values are both 24, so the median is 24.
To find Q1 and Q3, we need to split the data set into two halves at the median and find the medians of each half. The lower half of the data set consists of:
17, 19, 21, 23, 24, 24, 25, 26, 29, 29
The median of this half is (24 + 23) / 2 = 23.5, which is closer to 23 than to 24. Therefore, Q1 is 23.
The upper half of the data set consists of:
31, 32, 34, 35, 36, 39, 49
The median of this half is (35 + 36) / 2 = 35.5, which is closer to 36 than to 35. Therefore, Q3 is 36.
Now we can calculate the IQR as:
IQR = Q3 - Q1 = 36 - 23 = 13
Therefore, the appropriate measure of variability for the given data is the IQR, which equals 13.
