Mr. Whittaker’s science class uses tide gauges to measure annual variations in water levels at different parts of a river, and t
hen compares those variations to the average annual trend. Matea recorded that the water level in one part of the river fell 1.05 millimeters per year for 2.48 years. This data will be compared to the average annual trend, which shows the water level rising 1.8 mm/year. Which number represents the rate at which the water level fell? Which number should the rate be multiplied by to find the total variation in water level?

Therefore the Last option is correct
Step-by-step explanation:
Given:
Radius = r = 8 in
θ = 42°
To Find:
Area of Sector = ?
Solution:
We know that
Substituting the given values in the formula we get
Which is the required Answer.
Therefore the Last option is correct
Part I:
1. If you have to circle each outcome in the table that at least 1 die is a 4, then you have to circle row corresponding to the number 4 and column corresponding to the number 4.
2. If you have to cross out each outcome where the sum of the dice is greater than 5, then you have to cross out all not bold numbers 6, 7, 8, 9, 10, 11 and 12 in the table.
Part II:
Here you can see 36 possible outcomes.
1. The probability that at least 1 die is a 4 is:
- (favorable outcomes are 4+1=5, 4+2=6, 4+3=7, 4+4=8, 4+5=9, 4+6=10, 1+4=5, 2+4=6, 3+4=7, 5+4=9, 6+4=10).
2. The probability that the sum of the dice is greater than 5 is:
3. The probability that at least 1 die is a 4 and that the sum of the dice is greater than 5 is
4. The probability that at least 1 die is a 4 or that the sum of the dice is greater than 5 is:
We know that distance = rate(time). We need to solve for time here.
