What's the mean, median, and mode of 3, 5, 1, 5, 1, 1, 2, 3, 15.
lara [203]
<h3><em>Answer:</em></h3>

<em>mean = 4</em>

<em>Median = 3</em>

<em>Mode = 1</em>

Step-by-step explanation:

first let’s arrange the numbers from least to highest:

1 , 1 , 1 , 2 , 3 , 3 , 5 , 5 , 15

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

The median is the number that’s comes in the middle of the data set ⇒ median = 3  ( the fifth number in the data set)

1 , 1 , 1 , 2 , <u>3</u>, 3 , 5 , 5 , 15

________________________

The mode is the number that repeats the most ⇒ mode = 1  (repeated 3 times)

____________________________________

\text{the mean} =\frac{1+1+1+2+3+3+5+5+15}{9} = \frac{36}{9}=4

Find x and y. Give reasons to justify your solution
kkurt [141]

Answer:

Y=21

X=8

Step-by-step explanation:

In the middle there is a right angle

therefore 27 +3y=90

Y will be 21

Then x+27+63+8x+18=180

x=8

Hence 8+27+3(21)+8(8)+18=180

Select the correct answer from each drop-down menu.<br>​
horrorfan [7]

Answer:

4x^{5} - 16x^{3} + x^{2} - 4

Step-by-step explanation:

(0.5 x^{2} - 2) * (8 x^{3} + 2)

0.5 x^{2} *8 x^{3} = 4x^{5}

0.5x^{2} * 2= x^{2}

-2* 8x^{3}= -16 x^{3}

-2 * +2 = -4

so we have

4x^{5} - 16x^{3} + x^{2} - 4

Find the equation of the circle centre (3-2)radius 2 unit<br><br>​
il63 [147K]

Answer:

(x - 3)^2 + (x + 2)^2 = 4

Step-by-step explanation:

Equation of circle:

(x - h)^2 + (x - k)^2 = r^2

(h, k) = (3, -2)

r = 2

(x - 3)^2 + (x - (-2))^2 = 2^2

(x - 3)^2 + (x + 2)^2 = 4
