Compute the average (mean) from the data shown. (round to the nearest tenth) {89 , 36 , 49 , 98 , 40 , 79 , 28 , 86}

63.1

Step-by-step explanation:

to find the mean you first add up all the numbers. that gives you 505. then you divide that by however many numbers there are. there are 8 numbers so you would do 505/8. that gives you 63.12500 and rounded to the nearest tenth 63.1 ( or if you want you could make it a whole number 63)

Hope this helps!

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
