Answer:

X= 7 I hope this helped!

<u>Steps for equation/answer :</u>

1.Divide both sides by 3.

4x+9= 111/3

2.Simplify 111/3 to  37.

4x+9=37

3.Subtract 9 from both sides.

4x=37−9

4. Simplify  37-9  to  28.

4x=28

5. Divide both sides by 4.

x = 28/4

6. Simplify 28/4 to 7

x=7

suppose we flip a fair coin five times and each time it lands heads up. the probability of landing heads up on the next flip is
aleksley [76]

Probability is simply how likely something is to happen, so the probability of landing heads up on the next flip is 1/2.

<h3>How is probability determined?</h3>

The probability is obtained by dividing the total number of outcomes by the entire number of potential ways an event may occur. Odds are a separate concept from probability. The probability of an event happening is divided by the probability that it won't, and the result is the odds.

<h3>What is probability?</h3>

Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A value among 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty.

P(H)= Probability of getting  head while flipping a coin is 1/2

and,

P(T)= Probability of getting  tail while flipping a coin is 1/2

Hello BusyBunny, this is quite simple. All you would need to do is multiply .10 or 10% * $3.49 which will give you a 10% discount.

A researcher plans to identify each participant in a certain medical experiment with a code consisting of either a single letter
Digiron [165]

Answer:

at least 5

Step-by-step explanation:

<u><em>If the question was similar to the one given below </em></u>

A researcher plans to identify each participant in a certain medical experiment with a code consisting of either a single letter or a pair of distinct letters written in alphabetical order. What is the least number of letters that can be used if there are 12 participants, and each participant is to receive a different code?

<em><u>The answer would be as follows</u></em>

If we use 3 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get

4C2= 6 ways to use these letters and the comma

If we use 4 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get

5C2= 10 ways to use these letters and the comma

If we use 5 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get

6C2= 15 ways to use these letters and the comma

We need the least number of the alphabets to assign codes to 12 participants.

So the least number of alphabets is 5 because it can give codes to at least to  12 people .

Pair of alphabets + distinct letter ≥ 12

5 + 1  ≥ 12

6c2  ≥ 12

15  ≥ 12

Which of the following is the equation of a line in slope-intercept form for a
Triss [41]

Answer:

A

Step-by-step explanation:

Slope m = 2

The point is (0,3)

x1 = 0 and y1 = 3

And y - y1 = m(x - x1)

y - 3 = 2(x - 0)

y - 3 = 2x

y = 2x + 3 this is the equation
