Answer:
Pick c, 2/27
Step-by-step explanation:
Bag #1 has 4 + 6 + 3 + 5 = 18 total tiles.
4 are black.
So prob (black) from bag 1 = 4/18.
Bag #2 has 3 + 2 + 3 + 1 = 9 total tiles.
3 are black.
So prob(black) from bag 2 = 3/9.
Multiply those 2 independent probabilities together.
(4/18) x (3/9) = (2/27)

The coordinates of point S are (4, 3.5)
How to find the coordinates of point S?Remember that the coordinates of a point are written in the notation (x, y), such that the first value is the value in the horizontal axis, and the second value is the value in the vertical axis.
Each one of the squares is one unit, then the x-value of the point S is:
x = 4
And for the y-value we can see that the point is halfway between the third and the fourt lines, then:
y = 3.5

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

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.
Answers
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

Step-by-step explanation:
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
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
Answers
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.

Red: 0.3469
Blue: 0.2449
Green: 0.0816
Yellow: 0.2449

Probability (Green) = Frequency (Green) / Total Spins
= 4 / 49
= 0.0816 (rounded to four decimal places)
Probability (Yellow) = Frequency (Yellow) / Total Spins
= 12 / 49

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
Answers
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.

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).

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.
Answers
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 .
