Answer:

no, it is not

if it were a right triangle, 10² + 17² = 18²

but this is not the case

Step-by-step explanation:

we would use Pythagoras theorem to determine if it is a right angle

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

10² + 17² =

100 + 289 = 389

square root of 389 is 19.72 and not 18. thus, it is not a right triangle

Answer: According to Study Island the answer is 65

Step-by-step explanation:

In order to determine the outlier value, create a box plot.

To create a box plot, order the data.

5, 7, 8, 8, 9, 10, 12, 14, 15, 15, 19, 21, 23, 25, 26, 26, 27, 29, 30, 32, 32, 35, 40, 60, 65

Find the median, the first quartile (Q1), the third quartile (Q3), and the interquartile range (IQR).

Median = 23

Q1 =

10 + 12

2

= 11

Q3 =

30 + 32

2

= 31

IQR = Q3 - Q1 = 31 - 11 = 20

Find the upper and lower fences for the given data.

Lower Fence = Q1 - 1.5 × IQR

= 11 - 1.5 × 20

= -19

Upper Fence = Q3 + 1.5 × IQR

= 31 + 1.5 × 20

= 61

Answer:

15!

Step-by-step explanation:

so 40 people volentered to bring cakes, but 10 brought 2. So (30*1)+(10*2)=50 cakes. So, 30 percent of 50 cakes would be 15. To double check, times 50 by 100 and then 30 percent would become 30 (making super sure the actual answer is 15)

Answer:

2.2

Step-by-step explanation:

if force equals mass times acceleration then you divide 7.92(the force) by 3.6(the mass) to find out what would be multiplied by 3.6 to get 7.92.

Sorry if I'm wrong.

The acceleration of an object with F=7.92 newtons and m=3.6 kilograms is 2.2 m / s²

Force is a pull or push upon an object that causes motion .

Mathematically, force is express as follows:

F = ma

where

m = mass

a = acceleration

Force is measured in Newton.

Let's find the acceleration of an object with F =7.92 newtons and m = 3.6 kilograms.

7.92 = 3.6a

divide both sides by 3.6

a = 7.92 / 3.6

a = 2.2 m / s²

Answer:

Step-by-step explanation:

Expression evaluated by the student is,

(-4 + x)

For x = [tex]-9\frac{1}{2}[/tex]

Value of the expression will be,

(-4 + x) = [tex]-4+(-9\frac{1}{2})[/tex]

           = [tex]-4-9-\frac{1}{2}[/tex]

           = [tex]-13-\frac{1}{2}[/tex]

           = [tex]-13\frac{1}{2}[/tex]

While student evaluated the value of the expression as [tex]-5\frac{1}{2}[/tex].

Mistake done by the student may be in the first step [tex][-4+(-9\frac{1}{2})][/tex].

He might have subtracted [tex](-9\frac{1}{2})[/tex] from (-4).

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

Explanations:

To get the mean, you add up all of the values and then you divide by N, where N is the number of values in the list. In this case, you'll divide by N = 8.

Adding up all the values gets you 70+68+70+72+68+66+65+73 = 552. Dividing that over 8 then leads to the arithmetic mean of 552/8 = 69

-------

To find the median, you'll first sort the values from smallest to largest. You should have this set {65, 66, 68, 68, 70, 70, 72, 73} after sorting. Next, cross off the smallest and largest values to end up with this smaller set {66, 68, 68, 70, 70, 72}. We do this so we can locate the middle-most item.

Repeat the process of crossing off the smallest and largest items to get {68, 68, 70, 70}. Do so one more time and we get {68,70}.

The midpoint of those two values is (68+70)/2 = 138/2 = 69. The median is 69. The mean and median may not always be the same value.

--------

The mode is the most frequent value. In this case, we have 68 and 70 show up exactly twice for each unique value. This is the most compared to the other unique values that only show up exactly once.

It is possible to have more than one mode, as long those values are more frequent than the rest. We denote the mode as a set, so the mode is {68, 70}

Answer:

Step-by-step explanation:

Median - The middle number in a list of numbers starting from least to greatest.

Knowing this, we can start.

The first step is to rewrite all the numbers from least to greatest

15, 19, 28, 32, 43, 52, 66, 72, 72, 81

Now cross off a number from the least and greatest until there is 1 or 2 numbers left

19, 28, 32, 43, 52, 66, 72, 72

28, 32, 43, 52, 66, 72

32, 43, 52, 66

43, 52

If you are left we 1 number, that is your answer. If you are left with 2 numbers, there is an extra step

In the case that you have 2 numbers, you need to add them together, and divide by 2

43 + 52 = 95

95 ÷ 2 = 47.5

Thus 47.5 is our answer

Answer:

She has to make 25 consecutive free throws

Step-by-step explanation:

Let the number of consecutive throws be x

So, that would mean the number of free throws would total 25 + x

while the number of free throws made would be 15 + x

So for us to have an 80% raise ;

That would mean;

(15 + x)/(25 + x) * 100 = 80

100(15 + x) = 80(25 + x)

1500 + 100x = 2000 + 80x

2000-1500 = 100x-80x

20x = 500

x = 500/20

x = 25

Answer: C: A=18

Step-by-step explanation: If your are adding 5 every time the x value goes up by one, then you would add 5 to13, henceforth getting 18.

The value of a that completes the table is 18

The rate of change of a function is expressed in term of the slope.

In order to determine the value of a, we will use the expression below;

Slope = a - 13/4-3 = 23-13/5-3
a-13 = 10/2

a - 13 = 5

Add 13 to both sides

a =5 + 13

a = 18

Hence the value of a that completes the table is 18
