Answer:

y intercept is 140, slope is 2/1

Y intercept: when x = 0
Coordinate will be (0, y)
Look at the graph
Solution: y intercept: (0, 140)
Slope is the rate of change
(20,100) (0,140)
Slope formula: (y2-y1)/(x2-x1)
(140-100)/(0-20) = 40/-20 = -2
Solution: the slope is -2
Now use formula: f(x) = mx + b
m = slope, b = y intercept
Solution: function: f(x) = -2x + 140

When Lila conducted an experiment on citywide pond water, all of her samples came from the pond in her uncle's backyard. Explain
liq [111]

Her area of study is too narrow. There are other sources of water in the city that she is not considering. So her sample is too biased leaning toward the Uncle's pond water, and that leaves out every other source. We say that the Uncle's source of water is over-represented while the other sources are completely under-represented.

Let's put it this way: We have a hypothetical city that has 100 acres of pond water either in or surrounding the city limits. If the Uncle's pond only represents 1% of this, then she's ignoring the other 99% of the ponds.

What Lila needs to do to to fix this error is to draw up a map of each major pond and mark those ponds with numbers 001,002,...998,999. In this example, there are 999 ponds. Then she needs to either use a random number table or computer software to help randomly generate values to help select the ponds. Doing so will ensure that she spans a good portion of the city and not stay focused on just the narrow area of her Uncle's backyard.

The reason why she needs to enlarge her area of study is because the results of her Uncle's pond study may lead to the wrong conclusion of the city overall. Let's say his pond is contaminated somehow, and it's only his pond that's the unfortunate one. She would likely see the pond is contaminated and conclude that the whole city's water is ruined as well, which isn't the case. Or we could have nearly the entire city's pond water in trouble, but her Uncle's pond is one of the lucky ponds not to get contaminated. We can see that Lila would likely conclude that no action needs to be taken to clean up the city's water sources, which is also not the case.

If Lila only cared about her Uncle's pond, then that pond (and perhaps immediate close surrounding area) would be her population of study. However, her study is about citywide pond water which is why she needs to extend to other places in the city or in the outer surrounding areas.

A small tree was planted at a height of 9 feet. The tree has been planted for 16 months and is now 57 feet tall. Write an equati
bekas [8.4K]

Answer:

First you have to know what x and y mean in the equation. They told you in the problem that x is the avg # of feet the tree grew each month. That means that the number multiplied by x is the number of months.Y will be the total height. That number is 57.6. When y = 57.6, the number that should be multiplied by x is 16.The tree starts at 8 ft tall, not 0 feet, so the y-intercept in this equation should be 8, because even when 0 months have passed, it will be 8 ft tall. So you know the equation will have the +8 in it added to the slope times x part.It should be d. 16x + 8 = 57.6.
