about 117 hours bc there are about 52 weeks in a year. And one week of 3 lessons is 2 (1/4)hrs. And 2(1/4) × 52 = 117 hrs
Answer:
C. The principal randomly selects homeroom classes and surveys each student in the chosen classes.
Step-by-step explanation:
Middle school is 6-8th. Surveying only the eighth-grade students won't give a representative sample of the whole school only the eighth-graders. Option A is incorrect.
Surveying only the students in detention represents a very small amount of students compared to the school, therefore it is not a representative sample. Option B is incorrect.
Yet again, the students in the math club is a small amount of students compared to the school. It does not represent the entire, or majority of the population. Option D is incorrect.
Picking students from homeroom classes and surveying each will give a wider variation of opinions from each grade and therefore a representative sample. Option C is the correct answer.
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
also is this for edge cause im doing the same lesson rn
Do you know how to change the 1 hour to minutes
Circumference=Diameter*pi
56.5=3.14*D
Divide both sides by 3.14
D=17.99
Diameter= 2(radius)
17.99= 2r
Divide both sides by 2
The radius is about 8.995 or 9m
