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.

Answers

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.

x = -4y + 9
x - y = 4

Answers

Answer:

please what should we found? is it the value of ×or y

x = -4y + 9
x - y = 4

- rearrange the second equation to x = 4 + y
- then we can plug it into x for the first equation

4 + y = -4y + 9 — then we solve for y
y = -4y + 5
5y = 5 -> y = 1

we can then plug in 1 (our y value) into the original second equation.

x - 1 = 4 -> x = 5

x = 5 & y = 1
you should put it in a coordinate layout so:

Find the length of the segment indicated. Round your answer to the nearest tenth if necessary

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!

Answer:

[tex]Accept = 69.44\%[/tex]

[tex]Reject = 11[/tex]

Step-by-step explanation:

Given

See attachment for dataset

Solving (a): Percentage to accept

The percentage to accept are flea collars that range between 14mg to 16mg (inclusive)

From the attachment, we have:

[tex]Total = 36[/tex]

[tex]n(14mg-16mg) =25[/tex] --- Number of 14mg to 16mg

So, the percentage to accept is:

[tex]Accept = \frac{n(14mg-16mg)}{Total} * 100\%[/tex]

[tex]Accept = \frac{25}{36} * 100\%[/tex]

[tex]Accept = 0.6944 * 100\%[/tex]

[tex]Accept = 69.44\%[/tex]

Solving (b): Collars to reject

In (a), we have:

[tex]n(14mg-16mg) =25[/tex]

The number to reject is then calculated by subtracting the collars to accept from the total (this is called complement rule)

So, we have:

[tex]Reject = Total - n(14mg - 16mg)[/tex]

[tex]Reject = 36 - 25[/tex]

[tex]Reject = 11[/tex]

11 will be rejected
