Round 2.643 to the nearest tenth

2.6

Step-by-step explanation:

the nearest tenth is located right where the 6 is in 2.643.

now you need to look at the number behind the 6→ 2.643.

if your numbers range from 1-4 then you round to zero

if your numbers range from 5-9 then you round up

2.643.

since the number behind the 6 is 4 then you round to zero

so 2.643 rounded to the nearest tenth is equal to 2.60 which is equal to 2.6

I hope this helped

Have a good day

step-by-step explanation:

p(x=0) = 0.25
