The equation |x − 8| = 3 represents the minimum and maximum percent of people in a survey who are undecided about an issue. What percent of the people in the survey are undecided about an issue?

Answers

Answer 1

Answer:

The equation represents the minimum x = 5 or 0.05% and maximum percent x = 11 or 0.11% of people in a survey who are undecided about an issue.

Given that,

Equation |x − 8| = 3 ,

The minimum and maximum percent of people in a survey who are undecided about an issue.

We have to find,

What percent of the people in the survey are undecided about an issue.

According to the question,

Equation, |x − 8| = 3

The equation with mod solving two time with positive and negative sign.

On solving the equation,

$x - 8 = 3\n$

Adding 8 both the sides,

$x - 8 + 8 = 3 +8\nx = 11$

And Again solving with (-) sign,

$- (x-8) = 3\n-x + 8 = 3$

Subtract 8 from both sides,

$-x + 8 - 8 = 3-8\n- x = -5$

Divided by (-) both the sides,

x = 5

The minimum 0.05%.

Hence, The equation represents the minimum x = 5 or 0.05% and maximum percent x = 11 or 0.11% of people in a survey who are undecided about an issue.

Answer 2

Answer: | x - 8| = 3

x - 8 = 3 - (x - 8) = 3
x = 3 + 8 -x + 8 = 3
x = 11 -x = 3 - 8
-x = - 5
x = 5

Minimum : 5% Maximum : 11% if u need them added it is 16%

Please help will give brainliest!CheapBuys, a large bulk store, sells cases of bottled water for $13.49. There are 48 bottles in each case and the bottles are 12 ounces each. Sarah remembers that the vending machine at work sells the same size bottle for $0.75 per bottle. Calculate the cost for one bottle and tell if Sarah should buy bottled water by the case or not.

A: Buying in bulk will not save her any money since the bottles in the case and the bottles from the vending machine are both about 75 cents each.

B: The cost per bottle at CheapBuys is approximately 28 cents, so Sarah will save a considerable amount of money by buying water in bulk rather than from the vending machine.

C: Each bottle of water in the case from CheapBuys is 35 cents, so she should buy the case instead of buying it at work.

D: The case of water is $13.49. Since the individual bottles are cheaper in the vending machine, Sarah should buy the bottles at work.

Answers

Answer: B

Step-by-step explanation:

$13.49 ÷ 48 = $0.28 per bottle in the case

Answer:

Step-by-step explanation:

Step 1:

Cost of 1 case of water with 48 bottles - $13.49

Step 2:

Calculate cost of 1 bottle of water - (Cost of 1 case)/(Number of bottles)

13.49/48 = $0.28

I am in a game show.In this game show there are 3 doors. Behind one of these doors lies a brand new and spectacular Ferrari, however, behind two of these doors lie nothing.

These doors are represented by the letters A, B and C respectively.

The host of this game show gives me the opportunity to win a Ferrari, and tells me that if I open the door which has this Ferrari sitting behind it, I will get to keep it. The problem is, I will only get to open one door. If it turns out to have nothing behind it, I will go home empty handed.

So, the game show host asks me which door I'd like to open. I select the door B.

Before the host opens the door B for me, he opens up the door C and shows me that nothing lies behind it.

This means that the Ferrari is either behind door A or door B.

Now, the host asks me if I'd like to open door A instead of door B. He gives me the chance to open door A. Should I open door A or should I open door B?

Would my chances of winning a Ferrari increase if I were to open door A instead of door B?

Explain your answer and justify why you are correct...

Answers

This is the well known Monty Hall problem.

You have more chances of winning by switching doors.

Let A,B,C denote the events "The ferrari is behind A" and so on
Let HA,HB,HC denote the events "The host opens A" and so on

By Baye's formula, $P(B)_(HC)=(P(HC)_BP(B))/(P(HC))=\frac{\frac{1}2\cdot\frac{1}3}{\frac{1}2}=\frac{1}3$ whereas $P(A)_(HC)=(P(HC)_AP(A))/(P(HC))=\frac{1\cdot\frac{1}3}{\frac{1}2}=\boxed{\frac{2}3}$ !!

if you switch after the host shows you the door without the ferrari, your chance of getting the car is greater.

we have 3 hypothetical situations.

if the car is in door A, but and then you pick door A, the host will open either door B or C and you will pick the other remaining door, resulting in a loss.

if the car is in door B, and you pick door A, the host will show you door C, and if you switch to door B, you will win.

if the car is in door C, and you pick door A, the host will show you door B, and if you switch to door C, you will win.

There is a 2/3 chance of winning a ferrari if you switch after the host shows you the door without.
