Gina surveyed students about their lunch time preference. Out of 50 students, 20 prefer eating lunch at 11:00am, 15 prefer eating at 11:15a.m., 10 prefer eating at 11:30a.m. , and 5 have no preference. Based on the information, what is the probability that a student chosen at random has no lunch time preference?
That 0.98% of people that have cats hate dogs and that 2 percent of people that have cats don't hate dogs.
If you add them all together, you'd get 157. Then you divide by 7 and you'd get 31.4
We want to find how many ounces of fertilzer we put for every 1 square meter
we have
(1/2oz)/(5/8m^2)
find x/1
(1/2)/(5/8)=x/1=x
remember, when dividing fractions, invert bottom one and multiply them
(1/2)/(5/8)=(1/2)(8/5)=8/10=4/5
answer is 4/5oz per square meter
The table is usually the shape of a rectangle. The area is equal to the length times the width. To make sure, let's recalculate the solution.
Area = length × width
Area = 103.50 cm × 73.75 cm
Area = <span>7,633.125 cm</span>²
So, we established that the answer is correct. Now, I'll introduce the concept of significant figures. There are rules regarding significant figures to be applied conventionally in measurements and calculations. This is to increase precision of the data. Significant figures are digits that carry meaning. When you are given data with a specific number of significant figures, the final answer should also contain the same number of significant figures. In convention, the rule says that the zero's after non-zero digits after the decimal point are significant. Also, all non-zero digits are significant. The value 103.50 has 5 significant figures, and 73.75 has 4. When it comes to multiplication, the answer should contain the least significant figures. So, we should have 4 significant figures. Therefore, the final answer to be reported should be 7,633 cm².
