Steve flipped a coin 10 times and recorded his results in this chart.

Part C: Did Steve’s EXPERIMENTAL result match the THEORETICAL probability of a coin landing heads up? If the probabilities are not the same, explain at least one possible reason for the difference.

Steve Flipped A Coin 10 Times And Recorded His Results In This Chart.Part C: Did Steves EXPERIMENTAL

Answers

Answer 1
They are not the same but very close, the reasoning for this is that theoretical things are not 100% accurate therefore meaning that the answers with a real experiment may vary.
Answer 2
it’s 100% accurate i did this before

Answer:

the answer is $102.20 because first lots are 8 of the and second lot are 7 of them,so 7×14.60=102.20

Answer:

Question 2: $102.20 collected second day

Question 1: x[tex]\leq[/tex]-5

Step-by-step explanation:

Question 2:

We know that there are 15 members total.  The first day 8 members paid and the remaining paid on the second day.  To find the second day total just subtract first day from total members and that leaves the number who paid on second day.

15-8=7

So now we know 8 paid on 1st day and 7 on 2nd day.  To find the total paid on either day just multiply cost of dues by number who paid that day.

14.60*7=102.2

Question 1:

First let's make an equation with info from picture...

In first box there are 4 of the rectangles and the Key tells us they represent x.  We also have 12 white squares the Key tells us represents 1 each.  So first box is...

4x+12

Second box has 8 shaded squares that Key tells us represents -1 each.  So second box is...

-8

Our equation to solve with these values would be...

4x+12[tex]\leq[/tex]-8

4x[tex]\leq[/tex]-20

x[tex]\leq[/tex]-5

Answers

okay so we know that a circle is 360°

the one angle is 135 degrees and to find the other one we can just subtract 360 - 135

the other angle is 225°



we can set it up as:

12 yd x
——— = ——-
225 135


to find x, cross multiply 135 and 12 which gives you 1,620
1,620 / 225 = 7.2

the other angle is 7.2 yards!

Answers

-4(x-1)=-3x+13-9-x
-4x+4=-3x+4-x
-4x+4=-4x+4
-4x=-4x
0=0

Answer:

x can be any real number.

Step-by-step explanation:

- 4 (x - 1) = - 3x + 13 - 9 - x

The easiest approach to solving this problem is to simplify each side. Start by focusing on the left side, distribute the term outside of the parenthesis, multiply every term inside the parenthsis by the term outside of it,

- 4 ( x - 1 ) = - 3x + 13 - 9 - x

Distribute,

(-4)(x) + (-4)(-1) = - 3x + 13 - 9 - x

Simplify,

-4x + 4 = - 3x + 13 - 9 - x

Simplify the right side of the equation, combine like terms,

-4x + 4 = - 3x + 13 - 9 - x

Rearrage,

-4x + 4 = -3x - x + 13 - 9

Simplify,

-4x + 4 = -4x + 4

At this point, one should use inverse operations to solve the problem, but the given equation is an identity, meaning that any real value can be substituted into the parameter (x), and the equation will yield a true result. Thus, (x) equals all real numbers.

What is the measure of ∠KMN?
A. 29 degrees
B. 66 degrees
C. 53 degrees
D. 89 degrees

Answers

Answer:

  ∠KMN = 66°

Step-by-step explanation:

In ΔKMN,

∠MKN + ∠KNM + ∠KMN = 180       {Angle sum property of triangle}

39 + 75 + ∠KMN = 180

       114 + ∠KMN = 180

               ∠KMN = 180 - 114

           ∠KMN = 66°

Answer:

B) 66

Step-by-step explanation:

75+39=114

180-114=66
