Answer:

-3/1

Step-by-step explanation:

(3,8)   4,5)

5-8 divided into    4-3

-3/1

Mark the point (3,8) on  the coordinate plan on graph paper. Then go 3 down,1 right, and you'll reach (4,5)      (from left to right, from 3,8 to 4,5)

3 down means  negative 3

1 right  means positive 1

In circle B with m AC.

Answers

We need to find the angle measure of the minor arc which is [tex]\sf\widehat{AC}[/tex] . We note that the measure of a complete angle is 360 degree. So that ,

Using this :-

[tex]\sf : \implies \angle ABC + m\angle ABC = 360^o \\\\\sf: \implies 106^o + m\angle ABC = 360^o \\\\\sf: \implies m\angle ABC = 360^o - 106^o \\\\\sf: \implies \red{ m \angle ABC = 254^o }[/tex]

Hence the required answer is 254° .

Answers

Answer:

Hope this helped! <3

Step-by-step explanation:

the median for number 1 is: 7.5 and the mean is 9.16667

the median for number 2 is: 100 and the mean is 90.4

the median for number 3 is: 10.5 and the mean is 18.16667

Answer:

Hi!

number 1: median: 8, 12 or 10

number 2: median: 100

number 3: median: 12, 2 or 7

number 1: mean: 9.16

number 2: mean: 90.4

number 3: mean: 18.16

Step-by-step explanation:

The mean is just all the numbers added up in a data set divided by how many numbers are in the data set. That gets you the average

The median is just the number in the middle of the data set.

Also for the first the median is either 10 or both 8 and 12 Because there's not 1 number in the middle it can be 8 and 12 of you want it averaged them it would be 10 I dont know which you want so you would have to figure that out

same with number 3

Also for the means it might vary depending if you need to round or not

Answer:

C. 1/3

Step-by-step explanation:

Replace each letter with their corresponding value and simplify using the order of operations:

a(b - c*c)

turns into:

[tex]\frac{2}{3} (\frac{3}{4}-(\frac{1}{2}*\frac{1}{2}))[/tex]

You want to remember that order of operations follows the rules of PEMDAS. The operations within the parentheses come first.

1/2 times 1/2 = 1/4

Now we have:

[tex]\frac{2}{3}(\frac{3}{4}-\frac{1}{4})[/tex]

Then 3/4 - 1/4 = 2/4 = 1/2

[tex]\frac{2}{3}(\frac{1}{2})[/tex] = 1/3

Therefore your answer is C. 1/3

Three friends will run race. If three friends no ties, in how many distinct order can these 3 friends finish the race?​

Answers

Answer:  6 different ways

===========================================================

Explanation:

Let's name the friends A, B, C

If person A is first, then B or C could be second and third.

So we have ABC or ACB as two possible outcomes.

If B is first, then either A is second or C is second. Meaning we have BAC or BCA.

If C is first, then we have CAB or CBA

Overall here are the 6 different ways to have the runners finish

ABC ... A is firstACB ... A is firstBAC ... B is firstBCA ... B is firstCAB ... C is firstCBA ... C is first

Note how for the first slot we have 3 ways to pick the winner. Then after that selection is made, we have 2 choices left, then 1 choice for third place. Therefore, 3*2*1 = 6 different outcomes are possible.

We can use the factorial operation on the calculator to do this with one button press, so we'd say 3! = 6. The exclamation mark means "multiply from 3 down to 1, counting down the whole time".

Another example of a factorial is:

5! = 5*4*3*2*1 = 120

Now that we’ve learned how to solve word problems involving the sum of consecutive integers, let’s narrow it down and this time, focus on word problems that only involve finding the sum of consecutive even integers.

But before we start delving into word problems, it’s important that we have a good understanding of what even integers, as well as consecutive even integers, are.

Even Integers

We know that even numbers are integers that can be divided exactly or evenly by 22. Thus, the general form of the even integer nn, is n = 2kn=2k, where kk is also an integer.

In other words, since even numbers are the multiples of 22, we can represent an even integer nn by 2k2k, where kk is also an integer. So if we have the even integers 1010 and 1616,

At Anthony's school, 260 of the 500 students are girls. At Theresa's school, 360 of the 600 students are girls. Whose school has the greater percent of girls.

Answers

Answer:

Theresa school has greater % of girls

Step-by-step explanation:

Given

Number of girl in the Anthony school = 260

Total student in Anthony school = 500

% of girl in the Anthony school = 260/500 * 100 = 52 %

Number of girl in the Theresa school = 360

Total student in Theresa school = 600

% of girl in the Theresa school = 360/600 * 100 = 60%

Theresa school has greater % of girls
