</span>Leah found that 25% of the students in her class
prefer ice cream for dessert
=> Now, if she has 24 students in her class. Let’s find out how many of her
students prefer ice cream for dessert.
=> 24 students = is the 100% of the number of student.
Now, 25% of it preferred ice cream as dessert. Lets solve
=> 25% / 100% = .25
Now, multiply this decimal with the value of our 100%
=> 24 * .25
=> 6, thus 6 of her students prefer ice cream for dessert.</span>
Answer:
0.
Step-by-step explanation:
If you take these two equations to a graphing calculator, you'll find that they are parallel. I. E. they don't intercept.

You measure two quantities as A=1.0m±0.2m, B=2.0m±0.2m. We should report correct value for
AB
as
Medium

Correct option is
D
1.4m±0.2m
Here, A=1.0m±0.2m, B=2.0m±0.2m
AB=(1.0m)(2.0m)=2.0m

AB
=
2.0m
=1.414m
Rounding off to two significant figures, we get
AB
=1.4m
