The last question: Did the majority of students pass the quiz (70% or Better)?

Answer:

33

Step-by-step explanation:

It's decreasing by 7

The relation is the descending the series by 7 and the next term is 33.

We have to determine, find the pattern and what numbers come next

We have given that, 61, 54, 47, 40.

What is the series?

A series is, roughly speaking, a description of the operation of adding infinitely many quantities, one after the other.

61-54=7

54-47=7

47-40=7

So the next term is

40-7=33

Therefore the relation is the descending the series by 7 and the next term is 33.

Answer: x>12 so anything greater than 12 is correct

Step-by-step explanation:

The solution to the given inequality is all values that are greater than 12.

Important information:

We have,

[tex]25x>300[/tex]

Divide both sides by 25.

[tex]\dfrac{25x}{25}>\dfrac{300}{25}[/tex]

[tex]x>12[/tex]

Therefore, the solution to the given inequality is all values that are greater than 12.

Solution :

a). This histogram is not a bell shaped.

    Here we cannot use the theorem of the central limit as the histogram is being plotted by using 365 samples data values of the one sample.

b). This histogram may be bell shaped approximately since the sample size is large.

   Here there are 50 sample each having a size of 500 and there is 50 sample proportions. The histogram shows sampling distribution of the sample proportion. Thus the central limit theorem can be used.

The histogram is approximately bell shaped as there is 50 samples of each having 500 size and an average of 50. Thus the central limit theorem can be used.

c). The histogram is not a bell shaped.

   In this case central limit theorem cannot be used as the histogram is plotted by using 100 sample data values of one sample.

d). The histogram is a bell shaped since the sample size is large.

   In this case 200 samples  of each having a size of 50 and a data values of 50. The histogram here shows a sampling distribution of the sample proportion. Thus the central limit theorem can be used.

In the second also the histogram is of bell shaped as the sample size is large.

There are 200 samples of each sample having a size of 40 and they have 40 data values , i.e. sum of rolls.

e). It is not a bell shaped.

  The histogram here is plotted using 100 sample data values having one sample. Therefore we cannot use the central limit theorem.

I just learned about this yesterday. The line inside of the box is the median. The left side of the box, on the number 2, is the lower quartile. The dot on the line to the left, outside of the box, is above the smallest value. The right side of the box is the upper quartile. The line outside of the box on the right is the highest value.

Answer:  r = 4cm/θ

Step-by-step explanation:

For a circle of radius R, the perimeter is:

P = 2*pi*R

Now, if we have an arc with an angle θ, the cord of this arc is:

C = (θ/2*pi)*2*pi*R

Where you can see that if θ = 2*pi (this is the full circle) we have the perimeter of the circle.

In this case, we can see that the cord for an angle θ is 4cm, then:

C = 4cm = (θ/2*pi)*2*pi*r = θ*r

Now we can solve this for r:

 r = 4cm/θ

Step-by-step explanation:

g(x) = - 2x + 5

Then

g(x) = - 5

- 2x + 5 = - 5

- 2x = - 5 - 5

- 2x = - 10

x = 10 / 2

x = 5

Answer: 1/6

Step-by-step explanation: To find the probability of rolling a six,

let's use our ratio for the probability of an event.

number of favorable outcomes / total number of outcomes

Since only one side of a die has a six on on it, the number of favorable

outcomes for rolling a six is 1 and since there are six sides to a die and it's

equally likely that the die will landy on any of these sides, the total number

of outcomes is 6.

So the probability of rolling a six is 1/6.

Step-by-step explanation:

Median - The middle number in a set a data

First, you need to list the numbers least, on the left, to greatest, on the right.

3, 3, 4, 5, 5, 5, 6, 8, 8

Once you have done this, you can follow these steps.

Cross off the lowest number. Cross off the highest number. Repeat until there is one or two numbers left.

3, 4, 5, 5, 5, 6, 8

4, 5, 5, 5, 6

5, 5, 5

5

Since there is one number left, that is the median. In case of there being two numbers left, you add them together. Then divide by 2 and that would be your median

Answer:

[tex](x,f(x)) = (-1,8)[/tex] -- Another point

[tex]a = 8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = a|x|[/tex]

[tex](x,f(x)) = (1,8)[/tex]

Solving (a): Another point

Substitute 1 for x and 8 for f(x) in [tex]f(x) = a|x|[/tex]

[tex]8 = a|1|[/tex]

Remove absolute bracket

[tex]8 = a*1[/tex]

[tex]8 = a[/tex]

[tex]a = 8[/tex]

Substitute 8 for a in [tex]f(x) = a|x|[/tex]

[tex]f(x) = 8|x|[/tex]

Let x = -1

[tex]f(x) = 8|-1|[/tex]

Remove absolute bracket

[tex]f(x) = 8*1[/tex]

[tex]f(x) = 8[/tex]

So, another point is:

[tex](x,f(x)) = (-1,8)[/tex]

Solving (b): The value of a

This has been solved in (a) above

[tex]a = 8[/tex]
