Answer:

Step-by-step explanation:

If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.

We have n = 50 and:

As per above described 2 to k rule, we are taking k = 6.

So 6 classes should be used.

0.05 x $980 = $49

$49 x 9 = $441.

Answer:

$266

Step-by-step explanation:

The amount did Ian pay, without tax,for the guitar is to be considered as the $266 when the off and discount are given.

Since the cost of the guitar is $350

There is 20% off.

And, there is 5% off the sale price

So, it be like

= 350 (1 - 0.20) (1 - 0.05)

= $266

hence, The amount did Ian pay, without tax,for the guitar is to be considered as the $266 when the off and discount are given.

Answer:

135°, 135° and 90°

Step-by-step explanation:

It is given a triangle with a right angle (90°) and the other two angles have equal measures, so they are both (45°)

exterior angles are thus 180 - 45, 180 - 45, 180 - 90

which are 135°, 135° and 90°.

Answer:

$42 dollars is the cost per dozen.

Step-by-step explanation:

3.50 is the cost for ONE muffin and we know that 12 goes into a dozen. Simply multiple 3.50 by 12 (3.50 X 12) to get your answer 42.

Answer:

42 dollars

Step-by-step explanation:

A dozen is equal to 12. A muffin is equal to 3.5 dollars each. Therefore, you have to multiply them together. 12 times 3.5 is equal to 42. Therefore, it is 42 dollars a dozen.

Answer:

x=88

Explanation:

x+6+x-2=180

2x+4=180

2x=180-4

2x=176

*divivd both sides*

x=88

Answer:

x = 88

A = 94°

B = 102°

C = 86°

D  = 78°

Step-by-step explanation:

We find the angle measurements by finding x first.

what we first do in this equation x+6+x-2=180 is combine like terms

this would equal

2x+4=180

we want x by itself so we subtract 4 from both sides

this would equal

2x=176

x is still not by itself so now we divide 2 by both sides

this would equal

x = 88

Now we just plug in our answers in to the angles meaning

we replace everything that is x in the quadrilateral with 88

Now that we found all the sides with equations there is still one angle that is undefined

We figure this out by subtracting all the angles with 360.

this is because all the angles degrees added in a quadrilateral equals 360. so 360-258=102

so the angle measurement of angle B is 102

Step-by-step explanation:

Hello There!

We are going to convert each fraction to decimal form to make it easier to tell if the statement is true or false

[tex]\frac{2}{3} =.66\\\\\frac{2}{6}=.33[/tex]

.66 is greater than .33 therefore [tex]\frac{2}{3} >\frac{2}{6}[/tex] is a true statement

[tex]\frac{8}{10} =.8\\\\\frac{6}{5} =1.2[/tex]

1.2 does not equal 8 therefore [tex]\frac{8}{10} =\frac{6}{5}[/tex] is a false statement

[tex]\frac{1}{8} =.125\\\\\frac{1}{4}=.25[/tex]

.25 is greater than .125 therefore  [tex]\frac{1}{8} <\frac{1}{4}[/tex] is a true statement

[tex]\frac{2}{4} =.5\\\\\frac{1}{2} =.5[/tex]

.5 is equal to .5 therefore [tex]\frac{2}{4} >\frac{1}{2}[/tex] is a false statement

[tex]\frac{4}{10} =.4\\\\\frac{4}{6} =.66[/tex]

.66 is greater than .4 therefore [tex]\frac{4}{10} <\frac{4}{6}[/tex] is a true statement

Step-by-step explanation: have a nice day

Answer:

It is a really idealistic way to estimate probability.

It usually works well for random events where there is no restriction like:

"There are N elements in a set, the probability of randomly selecting any element is the same (so there is no restriction) meaning that for every single element, the probability is 1/N.

Now suppose that there are K elements (K < N) with a given characteristic, then the probability of randomly selecting one of the K elements out of the sett with N elements is equal to K times the probability of each element, this is:

P = K*(1/N) = K/N"

Then if a dice has 6 possible outputs, and we want to find the probability of getting a 3 or a 5, we need to find the quotient between the outcomes where we get a 3 or a 5 (2) and the total number of outcomes (6)

P = 2/6

Now let's go to the case in the problem:

We know that out of the last 20 games, your team won 18.

Then yes, your team won (18/20)*100% = 90% of their played games.

Does this mean tath the probability of winning the next game is 90%?

Well no, because this is not a random selection, there are a lot of other things needed to analyze, as the win rate of the other team (suppose that the other team won 14 of their last 20 games, then their win rate is (16/20)*100% = 70%

Does this mean that the probability where our team wins is 90%, and the probability of the enemy team winning is 70%?

Well no, this makes no sense at all, and this is why this method is not a good way to estimate probability in complex cases like this one.

This is impossible. The answer is 0.2. Tell your teacher about the impossible problem.

Step-by-step explanation:

Let the shared amount be 2x and 3x Then

2x + 3x = £ 250

5x = £ 250

x =£250/ 5

x = £ 50

Now

2x = 2 *£ 50 = £ 100

3x = 3 * £50 = £150

Answer: 9n-18

Step-by-step explanation:

1. We distribute the 9 to the n and -2

2. 9n-2(9)

3.9n-18 is our answer.

Answer: 9n-18 would be equivalent to to 9(n-2)

Step-by-step explanation: First multiply 9 times n. Then multiply 9 and 2 and you get -18.

Answer:

f(y) = 4y2 - 4v

f(y) = 4y² - 4(-4) = 4y² + 16

f(y) = 4y² - 4(-3) = 4y² + 12

f(y) = 4y² - 4(-2) =4y² + 8

f(y) = 4y² - 4(-1) = 4y² + 4
