(5×6)-9+31-30-1=

(3x5)+(3x2)=

9+10=

if you know, you know

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

i think it’s c i believe

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
