vlada-n [284]

Answer:

The slope of the line that passes through these two points is 2/5

hope this helps ;)

Step-by-step explanation:

to find the slope (m) use the slope formula

m= y2-y1 / x2-x1

*plug in your points*

m= 4-2 / 3- -2    note here the <u>3- -2</u> changes to <u>3+2</u>

solve for m

m= 2/ 5  

slope= 2/5

A certain lot consisting of ten items has three defective items and seven nondefective items. How many possible subsets of 2 ite
Charra [1.4K]

Answer:

45

Step-by-step explanation:

The order in which the items are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

How many possible subsets of 2 items can be chosen from this lot?

Combinations of 2 from a set of 10. So

C_{10,2} = \frac{10!}{2!(10-2)!} = 45

If a rectangle measures 21 centimeters by 28 centimeters what is the length in centimeters of the diagonal of the rectangle
SOVA2 [1]

Answer:

35cm

Step-by-step explanation:

Given data

Length= 21cm

Width= 28cm

Diagonal= ???

Applying Pythagoras theorem

D^2= L^2+W^2

D^2= 21^2+28^2

D^2= 441+784

D^2= 1225

D= √1225

D= 35cm

Hence the diagonal is 35cm
