Answer:

Step-by-step explanation:

the distance around the figure--we need to find the perimeter

we have rectangle that has the side, 8 and 15

P(r)=2(8)+2(15)=16+30=46

we also have half of the circle with the diameter =8 and r=4

Circumference =2*3.14*r

C=2*3.14*4=25.12

we need just half of the circle 25.12/2=12.56

P figure=46+12.56=58.56

Area= rectangle=l*w=8*15=120

Area(circle)=3.14*r^2=3.14*16=50.24

half circle 50.24/2=25.12

Area figure=120+25.12=145.12

Jess rounds a number, x to one decimal place
The result is 9.8
Write down the error interval for X​

Answers

The error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.

The number that is rounded off is:

x = 9.8

9.8 can be rounded off for 9.75 to 9.84

So, this means that:

9.75 ≤ x

or 9.84 ≥ x

So, the error interval becomes:

9.75 ≤ x ≤ 9.84

Therefore, we get that, the error interval when x is rounded off to 9.8 will be given as 9.75 ≤ x ≤ 9.84.
