Quotient is Latin for "how many times" and it is the answer to a division problem.
560/7=80
we can prove this by doing it backwards
7*80=560
Answer:
y= 1/2x - 1
Step-by-step explanation:
TO FIND SLOPE: Count the rise over run. Rise= how much the next point RISES (on the y axis). Run= how much the next point RUNS (moves on the x axis)
TO FIND Y-INTERCEPT: Where the line meets the y axis. We see that the line crosses over on the -1.
We are given in the problem the data on the number of respondents, the mean and the standard deviation. In this problem, we find first the z-score through z = (65-62.5)/2.5 = 1. We find next the probability of this z-score then multiply the probability to the number of respondents. That is the answer
A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25 meters thick. Let y represent the ice sheet's thickness ( in meters) after x weeks. Complete the equation for the relationship between the thickness and number of weeks.
Answer:
y = 2 - 0.25x
Step-by-step explanation:
From the question, the initial thickness of the ice sheet = 2 meters,
After 3 weeks, the thickness of ice sheet reduced to 1.25 meters
Hence, the difference in the thickness in 3 weeks is calculated as:
2m - 1.25m = 0.75m
The amount of changes that occurred in 3 weeks is given as:
= 0.75/3 = 0.25 meters,
We are told that, the ice is melting with the constant rate.
Therefore, the equation for the relationship between the thickness and number of weeks is given as:
y = 2 - 0.25x
