5 0

The variance of a population can be completed with the following steps:

Compute the mean of the measurement.

Take the difference between each element in the population and the mean.

Square that difference.

Sum the squares of the difference.

Finally, divide by the number of measurements in the population.


Hope this helped!!!XD

Assume y = 100 − 2x. If x goes up by 3, the corresponding y-value changes by:
frutty [35]

Given: y = 100 - 2x

New: y = 100 - 2(x + 3)

           = 100 - 2x - 6

           = 94 - 2x

The original equation had a y-intercept of 100.  The new equation has a y-intercept of 94.  The y-value changes -6 units

Answer: -6

Working together,edith and rupert can pick 3 quarts of blueberries in an hours.how many quarts can they pick in 7 hours?
expeople1 [14]
Since they pick 3 quarts in 1 hour they can pick 6 quarts in 2 hours and 9 quarts in 3 and so on. So the number of quarts they can pick in a certain amount of hours is just the total number of hours they spend picking times 3 quarts. So since they picked for 7 hours and each of those hours they picked 3 quarts, in total they picked 21 quarts

7 x 3 = 21 quarts

e-lub [12.9K]

Answer: After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.


Step-by-step explanation:

Given: Sharon is conducting research on two species of birds at a bird sanctuary.

The number of birds of species A is represented by the equation below,where S represents the number of birds, x years after beginning her research.

S=2^x+12

The number of birds of species B is represented by the equation below,where S represents the number of birds, x years after beginning her research.

S=15x+35

To plot the above function, first find points by which they are passing.

For species A, At x=0 , S=1+12=13

At x=2 , S=2+12=14

Similarly find more points and plot curve on graph.

For species A, At x=0 , S=0+35=35

At x=2 , S=15+35=50

Plot a line with the help of these two points.

Now, from the graph the intersection of curve (for A) and line (for B) is at (7,140) which tells that After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.
