How to determine the valueIt is important to note that the Pythagorean theorem is stated as;
The Pythagorean theorem states that the square of the longest leg or hypotenuse side of a triangle is equal to the sum of the squares of the other two sides.
This is represented as;
x²= y²+ z²
Now, substitute the values, we get;
x² = 11. 9² + 7.9²
Find the square values, we have;
x² = 141. 61 + 62. 41
add the values, we have;
x² = 204. 02
Now, find the square root of both sides, we get;
x = √204. 02
x = 14.28

A company studied how much they pay employees. They found the mean and median annual salaries. These values are given in the table.
Annual Salary Data
Mean Annual Salary $62,000
Median Annual Salary $35,000
Which measure of center is best to describe salaries at the company? Select the statement that BEST explains your choice.
a. the mean, because people who earn too little make the median too small
b. the mean, because most workers earn a salary that is near this value
c. the median, because it is the measure of center with the lower value
d. The median, because people who earn a lot make the mean too large
The best measure of center to describe salaries at the company is the median. The Option D is correct.
Why is median best measure to describe salaries?The reason is that the median is less affected by extreme values or outliers which can greatly affect the mean. In this case, the mean annual salary is $62,000 while the median is only $35,000.
This large difference suggests that there are some very high earners at the company that are pulling up the mean. The median indicates that half of the employees earn less than $35,000 and half earn more which gives a more accurate picture of the typical salary at the company.

when given angle measures of 25,65,and 90,is it possible to draw a triangle,possible to draw only one triangle,or possible to draw more than one triangle?explain.
The total angle measurement of a triangle sum above is 180°. So yes, it is possible to only make a right angle triangle but impossible to draw a triangle
What is the triangle?To check if a triangle can be drawn with 25°, 65°, and 90° angles, we use the Triangle Angle Sum Theorem stating that all triangle angles add up to 180 degrees.
If you add all the angles together (25 + 65 + 90 = 180°), We can draw a triangle based on this sum, but we only consider the angles' nature. The triangle has angles of 25°, 65°, and 90°, making it a right triangle. It only applies to right triangle and not others triangle .
Note that based on the given angle measures of 25°, 65°, and 90°, it is impossible to draw a triangle as it does not follow the triangle inequality property.

According to the NCAA, 12.8% of high school men's lacrosse players will end up playing at the collegiate level. If 20 male high school lacrosse payers are selected at random, find the probability that exactly four of them will play at the college lacrosse. Express your answer as a probability between C and 1 and round to three decimal places.
This question involves using the binomial distribution.
Let X be the number of male high school lacrosse players who will play at the college level out of the 20 selected players . We can model X as a binomial random variable with parameters n=20 and p=0.128, where p is the probability of success (i.e., a player going on to play at the college level).
The probability of exactly 4 players playing at the college level is given by the formula:
P(X=4) = (20 choose 4) * (0.128)^4 * (1-0.128)^(20-4)
Using a calculator, we can evaluate this expression to find:
P(X=4) = 0.155
Therefore, the probability that exactly four of the 20 male high school lacrosse players selected at random will end up playing at the college level is 0.155, or between C and 1 (inclusive).
Note that we rounded to three decimal places as requested .

Based on the given data, the probabilities of the spinner landing on each color are approximately:
Red: 0.3469
Blue: 0.2449
Green: 0.0816
Yellow: 0.2449
Purple: 0.0816
To calculate the probability of the spinner landing on a specific color, we need to divide the frequency of that color by the total number of spins.
Given the spinner results:
Color Frequency
Red 17
Blue 12
Green 4
Yellow 12
Purple 4
To find the probability of landing on a specific color, we divide the frequency of that color by the total number of spins:
Probability (Red) = Frequency (Red) / Total Spins
= 17 / (17 + 12 + 4 + 12 + 4)
= 17 / 49
= 0.3469 (rounded to four decimal places)
Probability (Blue) = Frequency (Blue) / Total Spins
= 12 / 49
= 0.2449 (rounded to four decimal places)
Probability (Green) = Frequency (Green) / Total Spins
= 4 / 49
= 0.0816 (rounded to four decimal places)
Probability (Yellow) = Frequency (Yellow) / Total Spins
= 12 / 49
= 0.2449 (rounded to four decimal places)
Probability (Purple) = Frequency (Purple) / Total Spins
= 4 / 49

Answer:
(a) width = 71 ft; (b) length = 77 ft
Step-by-step explanation:
(a) The formula for area of a rectangle is
A = lw, where
A is the area in units squaredl is the lengthw is the widthBecause we're already given the area and length, we can find the width by plugging everything into the formula and solve for width, w:
6319 = 89w
71 ft = w
(b) The formula for perimeter of a rectangle is
P = 2l + 2w, where
P is the perimeterl is the lengthw is the widthSince we're given the perimeter and width this time, we can plug everything into the formula and solve for l:
272 = 2l + 2(59)
272 = 2l + 118
154 = 2l
77 ft = l
We can check our answers for (a) and (b) by plugging in the length and width for (a) into the area formula and seeing whether we get 6319 and plugging in the length and width for (b) into the perimeter formula and seeing whether we get 272
Checking answers for (a):
6319 = 89 * 71
6319 = 272
Checking answers for (b):
272 = 2(77) + 2(59)
272 = 154 + 118
272 = 272

Plot and connect the points A(4, 6), B(4, 0), C(1, -3), and D(1, 3), and find the area of the parallelogram formed.
Answer:
18 square units
Step-by-step explanation:
The parallelogram has been plotted in the attached figure
The area of a parallelogram is b x h
where b is one side and h is the vertical distance between the two bases
In the figure, we see that base = AB is parallel to the y-axis
This means the y-coordinates of A and B are the same and the distance is obtained by taking the absolute difference between the x-coordinates of A and B
b = |x1 - 2| = |6 - 0| = 6
The height h is a perpendicular line from point D(1, 3) to the base which touches the base at point E
Since this line is horizontal to the x-axis in the figure, the y coordinates of the endpoints of the line are the same i.e y1 =3 and y2 = 3
Therefore h = absolute difference between the x coordinates
= |1-4| = 3
Given b = 6, h = 3
area = 6x 3 = 18 square units

The graph of which equation passes through the point
(4, - 3) and has a slope 4
A.5x+4y=8
B.5x - 4y = 8
C.4x + 5y = 8
D.4x - 5y = 8
The equation that passes through the point (4, -3) and has a slope of 4 is option A: 5x + 4y = 8.
To determine which equation passes through the point (4, -3) and has a slope of 4, we can substitute the values of x and y into each equation and check if the resulting equation is true.
Let's substitute x = 4 and y = -3 into each equation:
A. 5x + 4y = 8
Substituting x = 4 and y = -3:
5(4) + 4(-3) = 20 - 12 = 8
The equation is true for points (4, -3).
B. 5x - 4y = 8
Substituting x = 4 and y = -3:
5(4) - 4(-3) = 20 + 12 = 32
The equation is not true for points (4, -3).
C. 4x + 5y = 8
Substituting x = 4 and y = -3:
4(4) + 5(-3) = 16 - 15 = 1
The equation is not true for points (4, -3).
D. 4x - 5y = 8
Substituting x = 4 and y = -3:
4(4) - 5(-3) = 16 + 15 = 31
The equation is not true for points (4, -3).
Therefore, the equation that passes through the point (4, -3) and has a slope of 4 is option A: 5x + 4y = 8.

Muya had a 6 2/3hectares piece of land. .He donated 7/8hectares to a school, and 1 1/2 to a children's home. The rest of the land was shared equally between his son and daughter .Find the size of the land
The size of the land that Muya's son and daughter received is [tex]1\frac{11}{12}[/tex] hectares.
We can see that, Muya started with a [tex]6\frac{2}{3}[/tex] hectares piece of land, which we can write as an improper fraction i.e.:
[tex]6\frac{2}{3}[/tex] = (6 × 3 + 2) / 3 = [tex]\frac{20}{3}[/tex] hectares
The Muya donated [tex]\frac{7}{8}[/tex] hectares to a school and [tex]1 \frac{1}{2}[/tex] hectares to a children's home. The total amount of land he donated is:
[tex]= \frac{7}{8}+ \frac{11}{2} \\\\= \frac{7}{8} + \frac{3}{2} \\\\= \frac{14}{8} + \frac{12}{8} \\\\= \frac{26}{8} \\\\= \frac{13}{4} hectares[/tex]
The size of the land left is:
[tex]\frac{20}{3} - \frac{13}{4} = (\frac{80}{12}) - (\frac{39}{12}) = \frac{41}{12} hectares[/tex]
Muya's son and daughter share this remaining land equally, so each of them gets:
[tex](\frac{41}{12}) / 2 = \frac{20.5}{12} = 1 \frac{11}{12} hectares[/tex]
Therefore, the size of the land that Muya's son and daughter received is 1 11/12 hectares.

Step-by-step explanation:
First, we need to arrange the data in order. We can convert the mixed numbers to improper fractions for ease of comparison:
1/3, 2/1, 4/1, 1/1, 7/3, 4/5, 5/2
Now, let's arrange them in ascending order:
1/3, 4/5, 1, 7/3, 2, 5/2, 4
The median is the middle value in the data set. Since we have an odd number of values, the median is the middle value when the data is arranged in order. Therefore, the median is:
median = 2
Therefore, the correct option is C
Answer:
1.5
Step-by-step explanation:
1/3 2 4 1 7 2/3 4/5 5/2
Write the numbers in ascending order.
1/3 2/3 4/5 1 2 5/2 4 7
The median is the middle value if there is an odd number of numbers.
If there is an even number of numbers, the median is the mean of the middle two numbers.
Here, there are 8 values, so we do the mean of the middle 2 values.
median = (1 + 2)/2
median = 1.5
the ratio of 2/3 to 8 as a fraction in simplest form
To write the ratio of 2/3 to 8 as a fraction in simplest form, we need to divide the numerator and denominator by their greatest common factor (GCF).The GCF of 2 and 8 is 2.So, we divide both the numerator and denominator by 2:2/3 ÷ 8/1 = (2/3) ÷ (8/1) = 2/3 x 1/8 = (2 x 1) / (3 x 8) = 2/24Now, we can simplify the fraction by dividing the numerator and denominator by their greatest common factor again.The GCF of 2 and 24 is 2.So, we divide both the numerator and denominator by 2:2/24 ÷ 2/2 = (2/24) ÷ (2/2) = 2/24 x 1/2 = (2 x 1) / (24 x 2) = 1/12Therefore, the ratio of 2/3 to 8 as a fraction in simplest form is 1/12.
Answer:
How to find Ratio?
Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B. For example, if A is five and B is 10, your ratio will be 5/10
In order to find the ratio of a certain number to another number or the relation of each other, we also need to know the concept of fraction and percentage.
1/12 or 1 to 12
The ratio is 2/3*8=23⋅8=2/24=1/12
