The Air Quality Index, or AQI, measures how polluted the air is in your city and assigns a number based on the quality of the air. Over 100 is “Unhealthy”.
The following quadratic regression equation gives us an estimate of n, which is the number of days the AQI exceeded 100 a particular year. We will use this equation to estimate the number of days the AQI was over 100 in the year 1995.
n = 1.76 t squared minus 13.32 t + 41.00
(Let t represent the number of years since 1990. Therefore, t = 0 corresponds to the year 1990. For the estimate of n, round to the nearest whole day.)

Find the equation of the line in slope-intercept form. a Slope of 2 and y-intercept of −7
Answer:
round 49,815,662 to the nearest hundred thousand
Answer:
49,800,000 is the answer
Answer:
50,000,000
Step-by-step explanation: What you would do is if you have to round up, remember this way to always get it right. 4 or below = stays the same 5 or above = rounds up. so 49,815,662. Well we would take the 8 and round it up to the 9 making it 10 so 49 turns into 50.
Two slices of dance famous pizza half 250 cal how many calories are in five slices of pizza
Answer:
625
Step-by-step explanation:
Since two slices is 250 calories, let us find how many calories is there in one.
250/2=125 (note, slash signs represents divide sign. When writing down, please write the actual sign.)
Now, we find how many calories are there in 5 pizza slices.
125x5=625

The life zones on Mount Rainier, a mountain in Washington, can be approximately classified by elevation, as follows.
Low-elevation forest: above 1700 feet to 2500 feet
Mid-elevation forest: above 2500 feet to 4000 feet
Subalpine: above 4000 feet to 6500 feet
Alpine: above 6500 feet to the summit
Write a compound inequality that represents the elevation range h
for each type of plant life.
Answer:
Look down below
Step-by-step explanation:
It's been a little while since I've looked at compound inequalities, so forgive me if this is a bit long.
Let's start with the Low Elevation Forest. Let x represent what is considered the forest. If this is above 1700, x>1700 (which can be rewritten as 1700<x). (Remember, as silly as this may sound, the mouth of the alligator eats the larger part! So the large number has the wide part of the symbol. Remember also that if the sign is < or >, then it includes the number the 'mouth' is facing.) If the forest is up to 2500, you'll generally include 2500 in your equation, so x<2500. This means 1700<x<2500 or x>1700 and x<2500.
Now let's repeat that with the other parts of the question. Mid elevation is x>2500 and x<4000. Subalpine would be x>4000 and x<6500. Alpine is then x>6500 and x< the summit (which is probably the elevation of Mount Rainer in this problem or 14410 feet).
Now we have the question itself. Let's replace x with t for trees for part a. This would mean in the low elevation forest, t>1700 and t<2500 which can be rewritten 1700<t<2500. Now we have flowers in the subalpine AND alpine zones. Let's use f for flowers. If flowers can be in either zone, let's combine them! Because t>4000 and t<6500 in the subalpine level and t>6500 and < the summit (aka 14410 feet), flowers can grow anywhere above 4000 feet. So flowers would be f>4000 and f<14410. Again, you can combine these into: 400<f<14410.
Sorry this is so long, but I hope it helps :)

The average a of two numbers c and d is equal to half the sum of c and d
Answer:
[tex]\frac{c + d}{2}= \frac{c + d}{2}[/tex]
Step-by-step explanation:
Required
Write the given statement as an equation
To start with, we solve for the average of c and d
[tex]Average = \frac{\sum x}{n}[/tex]
[tex]Average = \frac{c + d}{2}[/tex]
Next, is to determine half sum
[tex]Half\ sum = \frac{c + d}{2}[/tex]
Since both are equal; we have"
[tex]\frac{c + d}{2}= \frac{c + d}{2}[/tex]
The above shows that the statement is true

Tuberia, y cada tubo mide 6 metros de largo. ¿Cuantos tubos se necesitan?
Answer:
n = 641
Step-by-step explanation:
Pipe required to provide water is 3846 m
Length of each pipe is 6 m
We need to find the no of tubes required. Let there are n tubes. It can be calculated as follows :
[tex]n=\dfrac{3846 }{6}\\\\n=641[/tex]
Hence, 641 tubes will be needed.
90 minus 50 divided by 5 times 6 plus 2
Anwer:32
Step-by-step explanation:
Answer:
32
Step-by-step explanation:
To find out what to do first, use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, ans Subtraction)
Now it should look like this: (90-((50/5)*6)) + 2
First, divide 50 by 5 and get 10
So now it will be like this: (90-(10 x 6) + 2
Next, multiply 10 by 6 and you'll get 60.
The problem is looks like this: (90 - 60) + 2
Then, subtract 60 from 90 and get 30.
30 + 2
Lastly, add 30 and 2 to get 30.
Hope this helps.

Mrs. Powell is hiking up to the highest peak at the Rocky Mountains. What kind of slope would she have?
a. negative
b.positive
c.zero
d. unidentified
Answer:
Positive slope
Step-by-step explanation:
Because he's going up
Answer:
B, Positive
Step-by-step explanation:
Since Mrs. Powell is hiking UP,
the slope would also go up.
On a number line, the numbers going up get higher ( 1, 2, 3, ).
The altitude is getting higher, so numbers are being added.
A number with a plus ( + ) is positive.

Which is larger: 90%of 20 OR 20% of 95
Answer: 20% of 95
Step-by-step explanation: 20% of 95 is 19 and 90% of 20 is 18. So 19>18.
Hi! I believe your answer is ---20% of 95--- because 90% of 20 is 18, but 20% of 95 is 19, so that is larger. I hope this helps you! Good luck and have a great day. :)
