B. if the TV is unplugged, then the TV will not turn on.
A conditional statement has two parts: hypothesis (if) and conclusion (then).
The converse is when we switch or interchange our hypothesis and conclusion.
So, we have given statements as:
A. if an ambulance has emergency lights on, then cars on the road pull over.
B. if the TV is unplugged, then the TV will not turn on.
C. if the wind is blowing, then the weather is chilly.
D. if the light bulb was recently on, then the lightbulb is hot.
If we see the converse statement of C.
If the tv does not turn on it’s unplugged.
So the statement is true in both the ways.

You flip a fair coin until you see three tails in a row. What is the average number of headsthat you’ll see until gettingTTT?
Answer:
14
Step-by-step explanation:
From the given information:
suppose, Y is the number of times a coin is being flipped.
If the coin is flipped for the first time and we get H, then we have:
TTT = [tex]\dfrac{1}{2}(Y+1)[/tex]
Afterward, if we get H, then we waste two times plus the probability of this event [tex]\dfrac{1}{4}[/tex].
Therefore, we have : [tex]\dfrac{1}{4}(Y+2)[/tex]
Afterward, if we get H, then we waste three times plus the probability of this event [tex]\dfrac{1}{8}[/tex].
Therefore, we have : [tex]\dfrac{1}{8}(Y+3)[/tex]
If we got T at the third time, then;
T = [tex]\dfrac{1}{8}(3)[/tex]
Thus, average number of headsthat you’ll see until gettingTTT can be expressed as:
[tex]= \dfrac{1}{2}(Y+1)+ \dfrac{1}{4}(Y+2)+ \dfrac{1}{8}(Y+3)+ \dfrac{1}{8}(3)[/tex]
= 14

A can factory requires 2 sheets of metal to make 36 cans and 10 sheets of metal to make 180 cans. The proportionality constant between the number of cans made and the number of sheets of metal used is 36 18 288 5
Answer:From the statement above, we can say that there is a direct relationship between the number of sheets used to the number of cans that can be made. That is, # of sheets is directly proportional to # of cans. We make an equation as follows:
let y = # of sheets
x = # of cans
y = kx where k is the proportionality constant
Assuming linear relationship of the two, we can use either data point as follows:
y = kx
2 = k(36)
k = 1/18
Therefore, the proportionality constant is 1/18.

Jennifer paid $13.37 for a pack of 12 pairs of sport socks. What was the price of a pair of sport socks
Answer:
Each pair of socks cost around $1.11 excluding taxes.
Step-by-step explanation:
To find how much it costs for one pair of socks, divide the cost with how many pairs there are.
13.37/12 = 1.11426...
Since we are determining the cost of each pair of socks, it's only justifiable if we round it to the nearest hundredths.
Therefore, a pair of socks cost around $1.11 excluding taxes.
4. Ariel loves to go to baseball games. This season she has already attended 23 New York Ducks games. If
Ariel attended nine more weekend games than weekday games, how many weekday games did she attend.
Answer: She attended to 7 weekday games.
Step-by-step explanation:
Let's denote our variables as:
Wd = number of weekday games that she attended.
We = number of weekend games that she attended.
We know that in total, she attended to 23 games, so we have:
Wd + We = 23.
"If Ariel attended nine more weekend games than weekday games" can be written as:
We = Wd + 9.
Then we have the system of equations:
Wd + We = 23.
We = Wd + 9.
The first step would be to replace the second equation into the first one, as:
Wd + We = 23.
Wd + (Wd + 9) = 23
Now we can solve this for Wd.
2*Wd + 9 = 23
2*Wd = 23 - 9 = 14
Wd = 14/2 = 7
She attended to 7 weekday games.
And:
We + 7 = 23
We = 23 - 7 = 16
She attended at 16 weekend games.
A student winds a strip of paper eight times round a cylinderical pencil of diameter 7mm. Use the value 22/7 for the to find the length of the paper( ignore the thickness of the paper)
As per the circumference of a circle, the length of the paper is 176 mm.
What is the circumference of a circle?The circumference of a circle is the total arc length of it.
The diameter of the pencil is(d) 7 mm
Therefore, the radius of the pencil is(r)
[tex]= \frac{d}{2} \\= 7/2 mm\\= 3.5 mm[/tex]
Now, the circumference of the cross-section of the pencil is
[tex]= 2[/tex](π)r units
[tex]= (2) (22/7) (3.5) mm\\= 22 mm[/tex]
Therefore, the length of the paper is

Answer:
The minimum and maximum temperatures in the house are 68.5°F and 76.5°.
To keep the house in heat, the minimum and maximum temperature is set to option 68.5°F and 76.5°F.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The equation |x – 72.5| = 4.
The minimum and maximum temperatures can be found by substituting +4 and -4 in x.
Minimum temperature,
⇒ [tex]|+4-72.5|=|-68.5|[/tex]
⇒ [tex]68.5[/tex]
Maximum temperature,
⇒ [tex]|-4-72.5|=|-76.5|[/tex]

Jamie will choose between two catering companies for an upcoming party. Company A charges a set up fee of $500 plus $25 for each guest. Company B charges a set up fee of $200 dollars plus 30per guest. How many guests are need where the price is equal
Answer:
60 guests
Step-by-step explanation:
We'll say that the number of guests is n.
We're looking for the n where both of these expressions are equal:
Company A (500 set-up fee, 25 for each guest)
500 + 25 * n
Company B (200 set-up fee, 30 for each guest)
200 + 30 * n
500 + 25n = 200 + 30n
Subtract 200 from both sides.
300 + 25n = 30n
Subtract 25n from both sides.
300 = 5n
We'll reverse the sides.
5n = 300
Divide both sides by 5.
n = 300/5 = 60
Thus, both companies are equal when n is 60, or when there are 60 guests.

A projectile is launched from ground level with an initial velocity of 89 ft/sec. It's height(ft), t seconds after launching is given by s=-16t^2 + v0t + s0. a) Fine the time(s) the projectile will reach a height of 100 feet. b) find the time it takes the projectile to hit the ground
Answer:
Step-by-step explanation:
Initial Velocity of projection = 89ft/sec
height(ft), t seconds after launching is given by s=-16t^2 + v0t + s0
A) time the projectile will reach a height of 100 ft
s=-16t^2 + v0t
v0 = 89ft/sec
s = 100ft
100 = - 16t² + 89t
-16t² + 89t - 100 = 0

you can transform 4x + 12 = 9x - 3 again into a simpler form by subtracting 4x form both sides to get 12 = 5x - 3, if you subsitute 3 for x in 12 = 5x - 3, do you still get a true statement
Answer: Yes you will still get a true statement because 3 is the solution to the equation.
Step-by-step explanation:
Well substitute 3 for x into the equation and solve for to see if they equal each other.
12 = 5(3) - 3
12 = 15 - 3
12 = 12
So if you substitute 3 you get the solution .
Now solve for x in the real equation to see if you get 3.
4x + 12 = 9x -3
-4x -4x
12 = 5x -3
+3 +3
15 = 5x
x = 3
