Drag each label to the correct location on the chart.

Answer:

Maintains Biodiversity: A and D

Increase Biodiversity: B and C

Step-by-step explanation:

"Aug 23, 2019 — Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans."

~National Geographic Society

i make this note because it explains this point in a way that is understandable, with this, we can see why planting more trees -making more room and suitable habitat for animals- could maintain (or possibly increase) biodiversity where as dumping sewage water -killing a lot of marine life due to chemicals in the sewage or trash such as plastic items- would decrease it

hope this helps you out :)

The housing market has recovered slowly from the economic crisis of 2008. Recently, in one large community, realtors randomly

Gwar [14]

Answer:

Step-by-step explanation:

Given that the housing market has recovered slowly from the economic crisis of 2008. Recently, in one large community, realtors randomly sampled 38 bids from potential buyers to estimate the average loss in home value.

s = sample std deviation = 3000

Sample mean = 9379

Sample size n = 38

df = 37

Std error of sample mean = $\frac{s}{\sqrt{n} } \\=486.66$

confidence interval 95% = Mean ± t critical * std error

=Mean ±1.687*486.66 = Mean ±821.003

=(8557.997, 10200.003)

a) If std deviation changes to 9000 instead of 3000, margin of error becomes 3 times

Hence 2463.008

b) The more the std deviation the more the width of confidence interval.

You have 50$ to spend at the carnival. First, you must pay $9.20 for an entrance ticket. Each snack costs $4.25, including tax.

asambeis [7]

50 - 9.20 = 40.80 so 40.80/ 4.25 = 9.6 but you can’t buy .6 of a snack so it’s 9

A single tree produces about 2.6 x 10^2 lb of oxygen each year.The Amazon rainforest has about 3.9 x 10^11 trees.About how many

inna [77]

So to multiply standard form we multiply the 2 numbers and the 2 indices separately.

$2.6*3.9=10.14$
$x^{2} * x^{11} = x^{13}$

So we've got $10.14*10^{13}$
However Standard form must be $1 \leq x \leq 10$ therefore we need to divide that by 10 but to get the same number we add one onto the power of 10.

So the answer is:

$1.014*10^{14}$ lbs of oxygen are produced in the rainforest each year.
