Answer and Step-by-step explanation:

How to know if the side lengths can form a triangle:

Add together two of the lowest numbers. If it is greater than the largest number, it can form a triangle.

13. Yes, these side lengths can form a triangle.

-- 4 + 5 = 9.

-- 9 is greater than 7, the largest length.

14. No, these side lengths can't form a triangle.

-- 2 + 3 = 6

-- 6 is equal to 6, not greater than.

15. Yes, these side lengths can form a triangle.

-- 2 + 4 = 6

-- 6 is greater than 5, the largest number.

16. Yes, these side lengths can form a triangle.

-- Don't get confused when you see that there are two side lengths that are the same (it means that this is an isosceles triangle); the rules still apply.

-- 2 + 8 = 10

-- 10 is greater than 8, the largest number.

17. Yes, these side lengths can form a triangle.

-- 5 + 6 = 11

-- 11 is greater than 9, the largest number.

18. Yes, these side lengths can form a triangle.

-- 4 + 5 = 9

-- 9 is greater than 8, the largest number.

I hope this helps!!

Compute the standard deviation of the following set of data to the nearest whole number: 8, 12, 15, 17, 18

attashe74 [19]

We have that

set of data [8, 12, 15, 17, 18]

step 1
Find the mean
[8+ 12 + 15 + 17 + 18]/5-------> 70/5------> 14

step 2
for each number: subtract the Mean and square the result
(8-14)²----->36
(12-14)²----> 4
(15-14)²----> 1
(17-14)²----> 9
(18-14)²----> 16

step 3
 work out the mean of those squared differences
[36+4+1+9+16]/5-----> 66/5-----> 13.2----> this value is called the "Variance"

step 4
Take the square root of that
standard desviation=√13.2-----> 3.63-------> 4

the answer is
4

two cars start from two towns 400 miles apart and travel towards each other. They pass each other after 4 hours. find the speed

Gemiola [76]

use an expression
s = speed of the slower car
then
(s+20) = speed of the faster car

When they meet is after 400 miles

Write distance equation

slow car d + fast car d = 400 mi
4s + 4(s+20) = 400

8s + 80 = 400

8s = 400 - 80

8s = 320

s = 40 m/H

How many ways can you arrange your 3 statistics books, 2 math books, and 1 computer science book on your bookshelf if (a) the bo

katrin [286]

Answer:

720 different ways.

Step-by-step explanation:

Permutation has to do with arrangement. For example, in order to arrange 'n' objects in any order, this can only be done in n! ways since there is no condition or restriction on how to arrange the objects.

n! = n(n-1)(n-2)... (n-r)!

If there are 3 statistics books, 2 math books, and 1 computer science book on your bookshelf, the total number of books altogether is 3 + 2 + 1 = 6 books.

The number of ways that 6 books can be arranged in any order is 6!.

6! = 6(6-1)(6-2)(6-3)(6-4)(6-5)

6! = 6*5*4*3*2*1

6! = 120*6

6!= 720 different ways.

Hence, the books on your shelf can be arranged in 720 different ways.
