Step-by-step explanation: Coplanar points are points that lie in the same plane. Collinear points are points that lie in the same line. It does not mean that coplanar points are immediately collinear.
In a classic Conan Doyle story, Sherlock Holmes solves a crime mystery by recognizing that a guard dog didn't bark. Therefore, the dog must have known the perpetrator. Holmes' reasoning goes like this: if the guard dog doesn't know a person, then it barks. The dog didn't bark. Therefore, it knew the person.
Which rule of inference is being used here?
a. Addition.
b. Simplification.
c. Conjunction.
d. Modus Ponens.
e. Hypothetical Syllogism.
f. Disjunctive Syllogism.
g. Modus Tollens.
h. Resolution.
Answer:
G. Modus tollens
Step-by-step explanation:
This question used the inference called modus tollens.
Modus tollens is a a valid form of argument that is of this form below:
If S, then T
if not S, then not T.
S = dog doesn't know perpetrator
Not S = dog knows who the perpetrator is
T = the dog barked
Not T = the dog did not bark.
So if we put this into the statement in bold letters, we would have:
The dog doesn't know perpetrator, so it barked.
And,
The dog didn't bark, so it knows the perpetrator.

A gardening company sells clay flower pots and plastic flower pots. There must be at least 2 pots in each shipment, but there cannot be more than 8 in a shipment. Additionally, the shipment must weigh less than 100 pounds. Each shipment container weighs 20 pounds, and there is 1 pound of packing material. A clay flower pot weighs 15 pounds, whereas a plastic flower pot weighs 7.5 pounds.
A) Suppose that Horace wanted to buy 2 clay pots and 5 plastic pots. Would he be able to get all the pots in one shipment? Explain how you determined your answer.
B) Suppose that Jaleesa wanted to buy 4 clay pots and 4 plastic pots. Would she be able to get all the pots in one shipment? Explain how you determined your answer.
Answer:
I am 100% Sure it's A) Suppose that Horace wanted to buy 2 clay pots and 5 plastic pots. Would he be able to get all the pots in one shipment? Explain how you determined your answer.
I think he would be able to get all the pots in 1 shipment because he spent too much time on making money and now he has enough for this.
Step-by-step explanation:
Therefore,he will get all the pots in one shipment.
What is the simplification?
Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
Here given that,
A gardening company sells clay flower pots and plastic flower pots. There must be at least 2 pots in each shipment, but there cannot be more than 8 in a shipment.
Additionally, the shipment must weigh less than [tex]100[/tex] pounds. Each shipment container weighs [tex]20[/tex] pounds, and there is one pound of packing material.
A clay flower pot weighs [tex]15[/tex] pounds, whereas a plastic flower pot weighs [tex]7.5[/tex] pounds.
A) Suppose that Horace wanted to buy [tex]2[/tex] clay pots and [tex]5[/tex] plastic pots.

I'm in need of some desperate help
Answer:
77/134 or 0.5746
Step-by-step explanation:
The approximate relative frequency is "the number of times that the event occurs during experimental trials, divided by the total number of trials conducted."
So we need to identify the number of times the event occured, the amount of times children chose sweet snacks, and the total number of trials conducted. So since the question wants the approximate relative frequency by column, we use the number 134 for the total number, and 77 for the number of times the event occurred. We then divide 77 by 134, which looks like this: 77/134. In decimal form, this equals 0.5746. It can't be simplified anymore in fraction form, so 77/135 would be another way to answer.
Find the equation of the line specified. The slope is 6, and it passes through ( -4,4)
a. y = 6x + 4
b. y = 6x - 20
c. y = 12x + 28
d. y = 6x + 28
Please select the best answer from the choices provided
Answer:
d. y = 6x + 28
Step-by-step explanation:
Since the slope and one point are given to us we can put this equation into slope-point form. This is [tex]y-y_{1}=m(x-x_{1})[/tex], so this equation would be y-4=6(x+4). Then solve for y to get the final equation. Once solved for y the slope-intercept equation is y = 6x + 28.

Answer: should be 3.5
Step-by-step explanation:
Answer:3.5
Step-by-step explanation:
Three friends (A, B, and C) will participate in a round-robin tournament in which each one plays both of the others. Suppose that
P(A beats B) = 0.5
P(A beats C) = 0.6
P(B beats C) = 0.9
and that the outcomes of the three matches are independent of one another.
a. What is the probability that A wins both her matches and that B beats C?
b. What is the probability that A wins both her matches?
c. What is the probability that A loses both her matches?
d. What is the probability that each person wins one match? (Hint: There are two different ways for this to happen.)
Answer:
0.27 ; 0.30 ; 0.20 ; 0.21
Step-by-step explanation:
Given that :
P(A beats B) = 0.5
P(A beats C) = 0.6
P(B beats C) = 0.9
Since the outcomes are independent :
A.) probability that A wins both her matches and that B beats C
P(A beats B) * P(A beats C) * P(B beats C)
0.5 * 0.6 * 0.9 = 0.27
B.) probability that A wins both her matches
P(A beats B) * P(A beats C)
0.5 * 0.6 = 0.3
C.) probability that A loses both her matches?
(1 - P(A beats B)) * (1 - P(A beats C)
(1 - 0.5) * (1 - 0.6)
0.5 * 0.4 = 0.20
D.) probability that each person wins one match
Either (A beats B), (B beats C). (C beats A) OR (A beats C), (C beats B), (B beats A)
Hence;
(0.5 * 0.9 * (1 - 0.6)) + (0.6 * (1 - 0.9) * (1 - 0.5)) = 0.21

Write an equation of a line that passes through the point (2,0) and is perpendicular to the line y=−12x+3.
Answer:
Equation of a line that passes through the point (2,0) and is perpendicular to the line y=−12x+3 is
[tex]y = 2x-4[/tex]
Step-by-step explanation:
Slope of the line y=−12x+3 is m1=-12
We know slopes of perpendicular lines are negative reciprocals of each other. Therefore m2=2
Equation of line in point slope form is
[tex]y-y_1 = m_2 (x-x_1)[/tex] ----------- (1)
Here
[tex]m_2 = 2 \ \ \ and \ \ \ (x_1, y_1) = (2, 0)[/tex]
Substituting values in equation (1)
[tex]y-0 = 2 (x-2)[/tex]

Jessie is going to the county fair. The cost of admission is $5.00 and it is $2.00 for each ride. If Jessie has $19.00, Write an equation to determine how many rides Jessie can ride.
Answer:
x=7, Jessie can ride 7 rides with $19
Step-by-step explanation:
The cost of admission is $5.00 and it is constant,
Then for each ride the cost is $2.00
If we let the number of rides be X, then the cost function, C(X) will be given as
C(X)=5+2X
If Jessie has $19, then we can equate the cost function to $19 and solve for x
5+2x=19
Subtracting 5 on both sides,
2x=19-5
2x=14
x=7

8 Prove that 8^6+4^11 is divisible by 17. Answer __*17
Answer:
262,144 goes in the blank
Step-by-step explanation:
8^6 = 262,144
4^11 = 4,194,304
4,194,304 + 262,144 = 4,456,448
4,456,448 ÷ 17 = 262,144
You can use the fact that 8 is cube of 3 and 4 is square of 2.
The value in the blank space given is [tex]2^{18}[/tex]
Given that:To prove that [tex]8^6+4^{11}[/tex] is divisible by 17Converting [tex]8^6+4^{11}[/tex] in terms of 2:[tex]8^6 = (2^3)^6 = 2^{3 \times 6} = 2^{18}[/tex]
[tex]4^{11} = (2^2)^{11} = 2^{2 \times 11} = 2^{22} [/tex]
Thus,
[tex]8^6 + 4^{11} = 2^{18} + 2^{22} = 2^{18}(1 + 2^{4}}) = 2^{18} \times 17[/tex]
Thus, it is multiple of 17 and thus, divisible by 17.
The value in the blank space given is [tex]2^{18}[/tex]

- A married couple decided to file their taxes jointly. Their joint (total) income for the
year is $155,920. Since the couple does not have any kids yet, they are required to
pay a 30% annual income tax rate.
How much does the couple have to pay in income taxes for the year?
Answer:
They will pay $46,776 in income taxes. The money they will have after income taxes is $109,144.
Step-by-step explanation:
Because this problem involves a deduction of a percentage, you first need to multiply 155,920 by 30% in its decimal form - .30.
Then, with that answer - 46,776 - you subtract it from their total income - 155,920 - and get 109,144.
Now you have what they lose and what they have after the deduction.
So, they will pay $46,776 in income taxes and keep $109,144.

2 1/3 can be rewritten as 2 6/18
now the sum can be calculated:
4 14/18 + 2 6/18 = 6 20/18 = 7 2/18
This is within the tolerance of 7 1/18 to 7 3/18, so it will fit.
