Answer:
As we can see the average for the thickness of a chickens egg shell is 0.311 mm and if we want to round this number to the nearest tenth we just need to see the second decimal place and round to one decimal place.
This second decimal place for this number is 1 and this number is
so then if we round to the nesrest tenth we will get:

Step-by-step explanation:
We use the following info in order to complete the qeustion:
Round the thickness of the shell to the nearest tenth.
0.3
0.5
0.92
9
As we can see the average for the thickness of a chickens egg shell is 0.311 mm and if we want to round this number to the nearest tenth we just need to see the second decimal place and round to one decimal place.
This second decimal place for this number is 1 and this number is
so then if we round to the nesrest tenth we will get:

The first one would be approximately -0.8. It has a negative slope and the data points are fairly close together.
The second one is almost a straight line so it would be very close to 1. I would say 0.97
The closer the data is to a straight line the closer the r value is to 1 or negative 1.
Hope this helps.
The arithmetic formula is expressed as an = a1 + d *(n-1)where n is an integer. Substituting from the given a1 = -12 and a27 = 66, 66 = -12 + d *(27-1). hence , d is equal to 3. a42 thus using the formula is equal to 111. The final answer to this problem is 111.
Answer:
DF^2=DH^2+HF^2
DF=√DH^2+HF^2
DF=√2(DH^2) {AS IT IS A CUBE THEN ALL SIDES ARE EQUAL}
DF=√2*11^2 {ALL SIDES OF A CUBE ARE EQUAL}
DF=√2*121
DF=√242
DF=15.555
THEREFORE,OPTION B..
