Answer:

1. Mean: 10 Median: 11 Mode: 13

2. Mean: 26.7 Median: 20.5 Mode: 20

Step-by-step explanation:

1. Mean: 6+7+11+13+13 = 50 then, 50/5 = 10

Median: 6, 7, 11, 13, 13 in the middle: 11

6- crossed

13- crossed

7- crossed

13- crossed

That leaves 11!

Mode: 13 appears two times. All the other numbers only appear once.

2. Mean: 0+20+20+30+40+70 = 160 then, 160/6 = 26.7 ( rounded to nearest tenth)

Median: 0, 20, 20, 30, 40, 70

0- crossed

70- crossed

20- crossed

40- crossed

20- crossed

30- crossed

They all are crossed, but the last 2 to be crossed are 20 and 30. The middle of those two numbers is 20.5 therefore, the median is 20.5!

Mode: 20 appears twice while the rest only appears once.

I hope this helps, good luck! :)

Help Please . its due in 5 hours and i cant find answers

dolphi86 [110]

Answer:

39 pi cubic inches

Step-by-step explanation:

The volume of a cone is (1/3)(area of the base)(height).

$V=\frac{1}{3}Bh$

Find the area of the circular base. The circumference of a circle is $C=2\pi r$ , so

$2\pi r = 6\pi\\\\r=3$

Now that you know the radius of the circular base, you can find its area:

$A=\pi r^2 = \pi(3^2)=9\pi$

The height of the cone is 13. Time to use the volume formula.

$V=\frac{1}{3}Bh\\\\V=\frac{1}{3}(9\pi)(13)\\\\V=39\pi$

How is the sum expressed in sigma notation? <br> 1/64+1/16+1/4 + 1 + 4

shusha [124]

9514 1404 393

Answer:

sum = ∑[n=1,5] 4^(n-4)

Step-by-step explanation:

First of all, you need to be able to describe the n-th term.

Here, we have ...

term #: 1, 2, 3, 4, 5

value: 4^-3, 4^-2, 4^-1, 4^0, 4^1

That is, the exponent of 4 is 4 less than the term number. So, the n-th term is 4^(n-4). The sum of the 5 terms shown is then ...

$\displaystyle sum=\sum_{n=1}^5{4^{n-4}}$

Find the volume of the prism.<br> 9km 8km 6km

HACTEHA [7]

The correct answer is option B which is the volume of the prism is 216 km³.

<h3>What is the volume of the prism?</h3>

A prism is a three-dimensional solid with a triangular base called a triangular prism. The volume of the triangular prism is equal to the product of the area of the base and the height of the prism.

The volume of the prism will be calculated by using the formula below:-

V = Area of the base x Height

Since the base is a right-angle triangle so we will calculate the area of the right-angle triangle.

V = Area of the triangle x Height

V = ( 1/2 ) x 8 x 6 x ( 9 )

V = 216 km²

Therefore the correct answer is option B which is the volume of the prism is 216 km³.
