Whenever he participates a race, he is the winner. either he participates the race or he is sick. he is not the winner. therefor he is sick write the argument form and test its validity.
A statement 'He is not the winner, then, he is sick.' is a valid argument.
To test the validity of a given argument, we need to see if we can find a counter-example that makes one of the statements non-valid. If after analyzing the statements we can't find a counter-argument, then we can conclude that the argument is valid.
Here we will find that the argument is valid.
We can write given statement as:
1) If he participates in a race then he is the winner.
2) Either he participates in the race, or he is sick.
3) He is not the winner, then, he is sick.
Now, from the first statement, we know that this person participates in a race, he wins.
From the second statement we know that he only participates if he is not sick, we can rewrite that one as:
"If he is sick, then he does not participate in the race".
Finally, from the third one, if he does not win, then he is sick.
This makes sense, he only does not participate when he is sick, then the only races where he is not the winner, are these races where he does not participate, and he does not participate only if he is sick, then this is a valid argument.
Concluding, the 3 statements are valid, as we can't find any counter-argument to any of these 3.
Therefore, a statement 'He is not the winner, then, he is sick.' is a valid argument.

A design engineer is mapping out a new neighborhood with parallel streets. If one street passes through (4, 5) and (3, 2), what is the equation for a parallel street that passes through (2, −3)?
y = 3x + 11
y = 3x − 9
y equals negative 1 third times x plus 1
y equals negative 1 third times x minus 7 thirds
The equation for the parallel street that passes through (2, -3) is: B. y = 3x - 9.
How to Find the Equation of Parallel Lines?Two lines that lie parallel to each other will have a slope (m) that is of the same value. The equation can be written as y = mx + b in slope-intercept form.
Find the slope of the line that passes through (4, 5) and (3, 2):
Slope (m) = change in y / change in x = (5 - 2)/(4 - 3)
Slope (m) = 3/1
Slope (m) = 3
The slope of a parallel line would also be 3.
Substitute (a, b) = (2, -3) and m = 3 into y - b = m(x - a):
y - (-3) = 3(x - 2)
y + 3 = 3x - 6
Subtract 3 to both sides of the equation
y + 3 - 3 = 3x - 6 - 3
y = 3x - 6 - 3
y = 3x - 9
Therefore, the equation for the parallel street that passes through (2, -3) is: B. y = 3x - 9.

Using the midpoint concept, the other endpoint of the segment is: G(18,-9).
What is the missing information?The problem asks for the coordinates of the other endpoint, given by point G.
What is the midpoint concept?The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
Hence the x-coordinate of G is found as follows:

x - 2 = 16
x = 18.
The y-coordinate of G is found as follows:

A 48.75 miles
B 487.5 miles
C 510.875 miles
D 5,108.75 miles
John chose D as the correct answer. How did he get
that answer?
Isabel can drive 510.875 miles with a gas tank that holds 15.1 gallons of gas.
Given that, Isabel’s car gets 33.5 miles per gallon
Her gas tank holds 15.1 gallons of gas
To find the Number of miles can Isabel drive on a full tank of gas
Let "x" be the miles drive with 15.1 gallons of gas
From given,
1 gallon = 33.5 miles
15.25 gallon = x miles
This forms a proportion and we can solve the sum by cross multiplying
1 × x = 15.25 × 33.5
x = 510.875
Thus, Isabel can drive 510.875 miles on a full tank of gas

StarWatch Camping Site Charge per person: £5 per night Tent pitch: (ground surface) < 10 m² at £12 per night > 10 m² at £15 per night Special offer: For every 5 nights you stay, only pay for 4. Lila and Wassim are planning a stay at the StarWatch camping site. They will: ● share a tent between them, both stay for a total of 10 nights, • use a tent with a rectangular base measuring 2.5 by 4.2 metres. The holiday is just 9 weeks away and they each plan to save £12 per week from now until their holiday. Will they save enough money to cover all their camping site charges? If the answer is 'yes' say how much extra money they will save. You must show all your working.
Yes, Lila and Wassim saved the extra money of £16.
What is defined as the total cost?A total is a complete or whole amount, or "to total" means to add numbers or destroy something. In mathematics, you total numbers by having to add them together; the result is indeed the total. Whenever you add 8 and 8, you get 16.For the given data in question;
Charge/person for Camping Site : £5 per night
Charges for Camping Site Tent = £15 per night for Tent pitch > 10m²
calculate the tent pitch;
Tent Pitch = 2.5 × 4.2 = 10.5 > 10
Total charges for tent = £15 per night
As, 2 Lila and Wassim sharing Tent
Total charges per night = Charge/person + Charges for Camping Tent
= 2× £5 + £15
= £25 per night
For every 5 nights of the stay, pay is 4.
Cost for 10 nights for two persons.
Lila and Wassim have to pay the cost for 8 Nights;
Total charges = £25 × 8 = £200
Lila and Wassim each plan to save £12 per week for 9 weeks.
Thus, the total Saving = 2 × 9 × 12 = £216
total Saving = 216 > 200
As, total savings of Lila and Wassim are £216 which are greater than the £200 cost of camping.
The extra money saved is;
= £260 - £200
= £16.
Therefore, Yes, Lila and Wassim will save sifficient money to cover all camping charges with extra saved money of £16.

We get the value of angle Q in the triangle PQR as 155 °.
We are given a triangle PQR.
We are also given that:
∠ P = 110 °
∠ R = 15 °
Now, we need to find ∠ Q.
We know that sum of the angles of a triangle = 180 °
This is called the angle sum property of a triangle.
So, we get that:
∠ P + ∠ Q + ∠ R = 180 °
Substituting the given values, we get that:
110 ° + ∠ Q + 15 ° = 180 °
125 ° + ∠ Q = 180 °
∠ Q = 180 ° - 125 °
∠ Q = 155 °
Therefore, we get the value of angle Q in the triangle PQR as 155 °.
