A ∩ C does not contains any element. So A and C is a disjoint event.
What is Disjoint Set?
Two sets are said to be disjoint sets if they have no element in common.
Here, S = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }
Event A = { 1, 3, 5, 7, 9 }
Event B = { 2, 3, 4, 5, 6, 7, 8, 9, 10}
Event C = { 2 }
Event D = { 2, 4, 6, 8, 10}
Now,
A ∩ B = { 3, 5, 7, 9}
B ∩ C = {2}
C ∩ D = { 2 }
A ∩ C = { }
Thus, A ∩ C does not contains any element. So A and C is a disjoint event.

Step-by-step explanation:
Answer:
x = 60
Step-by-step explanation:
The tick marks imply that all the sides are equal so this is an equilateral triangle. In an equilateral triangle all the angles are the same so since we know one angle is 60 we know the other two are 60 too.

2. A great circle has a circumference of 83.92 cm. Find the Surface
Area and volume.
Answer:
Surface Area = 560.41 cm2
Volume (if it's a sphere) = 9979.71 cm3 or around 10 liters
Step-by-step explanation:
1. The circunference formula is C = 2 * π * R
2. If C = 83.92cm, R is 13.356 cm --> R = C / (2π)
3. The surface area formula is A = π * R * R
4. For R = 13.356 cm, A = 560.41 cm2
5. Sphere volume is V = (4/3) * π * R * R
6. For R = 13.356 cm, V = 9,979.71 cm3
7. 1,000 cm3 = 1 liter, so V is aprox. 10 Liters
There are 8 sweets in a box. There are n jelly beans and the rest are cola bottles. Colin takes 2 sweets out of the box at random. Write an expression for the probability of getting 2 cola bottles. Give your expression as a single fraction and simplify fully.
Answer:
Probability expression = 1 - n/7 - n/8 + n^2 / 56
Probability single fraction based on example = 3/28
Step-by-step explanation:
Total sweets = 8. n jelly beans , 8 - n cola bottles
Prob (getting 1st cola bottle) = Cola bottles / Total sweets = (8-n) /8
Prob (getting 2nd cola bottle) = remaining cola bottles / remaining total sweets = (8 - n - 1) / (8-1) = (7-n) / (7)
Prob (getting both 1st & 2nd cola bottle) = [ (8-n) /8 ] x [ (7-n) / 7 ]
(1 - n/8) x (1-n/7) = 1 - n/7 - n/8 + n^2 / 56
Eg : 5 jelly beans , 3 cola bottles
Similarly, Prob (2 cola bottles) = 3/8 x 2/7 = 6 / 56 = 3/28
8 pounds 15 ounces of clay to make a bowl and twice as much to make a vase. If he had a 25 pound bag of clay available, did he have enough clay to make both items?
Answer:
He does not have enough clay to make both the bowl and the vase together with 25 pounds.There is shortage of 29 ounces or 1 pound 13 ounces.
Step-by-step explanation:
1 pound = 16 ounces
1 bowl requires 8 pound 15 ounces of clay = 8*16+15= 143 ounces
1 vase requires twice of the clay required to make a bowl = 143*2= 286 ounces
He had 25 pounds of clay= 25*16= 400 ounces
Total clay required in making a bowl and a vase is = 143+286= 429 ounces
But he has 400 ounces.
Therefore he does not have enough clay to make both the bowl and the vase together with 25 pounds.There is shortage of 29 ounces or 1 pound 13 ounces.

If the mean of the data below is 3.8, find m
x 1 2 3 4 5 6
f 1 4 7 m 6 3
Answer:
m = 1.8
Step-by-step explanation:
Given data is as follows :
x 1 2 3 4 5 6
f 1 4 7 m 6 3
We need to find the value of m if the mean of the data is 3.8.
Mean = sum of observations/no. of observations
So,
[tex]3.8=\dfrac{1+4+7+m+6+3}{6}\\\\22.8=21+m\\\\22.8-21=m\\\\m=1.8[/tex]
So, the value of m is equal to 1.8.

Answer:
Compound Interest = 9680
Step-by-step explanation:
The formula of Compound Interest: [tex]A = P(1 + \frac{r}{n} )^n^t[/tex]
Where;
A = Compound Interest
P = Principal amount
r = Rate of interest
n = amount of deposite annually
t = total time
Therefore:
[tex]A = 8000(1 + \frac{0.08}{1})^1^*^2^.^5[/tex]
[tex]A = 8000(1 + 0.08)^2^.^5[/tex]
[tex]A = 8000(1.08)^2^.^5[/tex]
A = 8000(1.21)
A = 9680
Therefore, the compound interest = 9680

If a line plot were to be made, the number of "X"s placed above the 2 would be ____
above the 3 would be
____
above the 4 would be _____
and above the 5 would be
_____.
Answer:
No. X's above 2: 1
Above 3: 1
Above 4: 3
Above 5: 3
Step-by-step explanation:
Drawing a line plot of a data set means that you record the number of times that particular value shows up in the set. 2 on the line plot would only have 1 'X' placed above it because there is only one 2 in the data set:
5, 5, 4, 3, 2, 5, 4, 4
3 would also have 1 'X' above it because there is also only one 3 in the data set:
5, 5, 4, 3, 2, 5, 4, 4
Similarly, 4 and 5 would both have three 'X's because there are three 4's and three 5's in the data set:
4's: 5, 5, 4, 3, 2, 5, 4, 4
5's: 5, 5, 4, 3, 2, 5, 4, 4

The width of a triangle of 7 feet longer than its length. Find the dimensions of the rectangle such that the perimeter of the rectangle is 162 feet
Answer:
Length = 37 feets
Width = 44 feets
Step-by-step explanation:
Given that :
Length = l
Width, w = 7 + l
Perimeter , P of rectangle = 162
Recall:
Perimeter of a rectangle = 2(l + w)
P = 2(l + w)
162 = 2(l + (7 + l))
162 = 2(l + 7 + l)
162 = 2(7 + 2l)
162 = 14 + 4l
162 - 14 = 4l
148 = 4l
l = 148 / 4
l = 37 feets
Width = l + 7
Hence,
Width = 37 + 7 = 44 feets

Consider the following pair of equations:
y = x + 4
y = - 2x - 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form. (20 points!)
Answer:
(-2, 2).
Step-by-step explanation:
y = x + 4
y = - 2x - 2
Substitute y = x + 4 in the second equation:
x + 4 = -2x - 2
x + 2x = -2 - 4
3x = -6
x = -2.
Now substitute x = -2 in the first equation:
y = -2 + 4 = 2.
Check the results by substituting for x and y in equation 2:
2 = -2*-2 - 2 = 4 - 2 = 2. - this checks out.
Answer:
(-2, 2).

which of the following cannot be the graph of a function of X?
Why not? Because it fails the vertical line test. Here it is possible to draw a single straight vertical line through more than one point on the curve. That's why choice D is not a function. Choices A,B,C are functions because it's impossible to draw a single vertical line through more than two points on the curve, and therefore we can say they pass the vertical line test.
Side note: choices B and C fail the horizontal line test, so these functions are not one-to-one.
