Round each number to the nearest tenth what is the best estimate for the answer to 38.94+65.43
Answers
Answer 1
Answer:
38.94 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down
38.94
The number is 4, so we round down. 38.94 becomes 38.9
65.45 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down.
65.43
The number is 3, so we round down. 65.43 becomes 65.4
38.9+65.4= 104.3
If you were to estimate 38.94+65.43, we round the number to numbers that we can easily calculate in our head. 38.94+65.43 becomes 40+65
40+65=105

y=-x+2 (equation one rearranged, label this equation equation three)
sub 3 into 2 x-(-x+2)=4 x+x-2=4 2x-2=4 2x=6 x=3 sub x=3 into equation one
3+y=2 y=-1
therefore x=3 and y=-1

A scale drawing of a living room is shown below: A rectangle is shown. The length of the rectangle is labeled 3 inches. The width of the rectangle is labeled 5.5 inches. The scale is 1 to 30. What is the area of the actual living room in square feet? Round your answer to the nearest whole number. 17 ft2 41 ft2 495 ft2 103 ft2
Answers
103 ft^2 take 3 and 5 and multiply it by 30 3*30=90 5.5*30=165 then divide them both by 12 to convert inches to feet 90÷12=7.5 165÷12=13.75 then multiply both dividends together 7.5*13.75=103.125 then round to the nearest whole number 103
Answer:
103 sq. ft.

Is a simple random sample (sometimes, always or never) valid?
Answers
A simple random sample is SOMETIMES valid.
This is cuz it can be different in another sample like the random on. It can be different options or different opinions. When its different it can be valid OR invalid. It can always be a different thought from a different set of people/animals/books or whatever the case is. That is why your answer would be SOMETIMES.
