It impacts humans because when we breath we are breathing all that pollution which affects your lungs
The sales person is making 3% so, we would simply multiply $1400 by .03
1400*.03
=$42
They made $42 dollars on a $1400 sale, pretty lousy if you ask me.
Answer:
Step-by-step explanation:
In a deck of 52 cards there are 4 aces.
Therefore the probability of obtaining an ace is:
P (x) = 4/52
The probability of not getting an ace is:
P ('x) = 1-4 / 52
P ('x) = 48/52
In this problem the number of aces obtained when extracting cards from the deck is a discrete random variable.
For a discrete random variable V, the expected value is defined as:
Where V is the value that the random variable can take and P (V) is the probability that it takes that value.
We have the following equation for the expected value:
In this problem the variable V can take the value V = 9 if an ace of the deck is obtained, with probability of 4/52, and can take the value V = -1 if an ace of the deck is not obtained, with a probability of 48 / 52
<span>The “partial quotients”
strategy uses place value and lets students to form on multiplication facts
with friendly numbers. Look at the problem 496 ÷ 4. There are three instances
of a student’s method to answering 496 ÷ 4. We could say that example C is more
effectual than the other two but it is vital to point out how the student is
thinking on comprehending. The students can multiply 4 x 20 over and over again
or use higher multiples of ten proficiently; they all touch the same solution.
The “partial quotient” way will work with any division problem.</span>

Answer:
Step-by-step explanation:
Given,
r=3
arc=3/2*pi
we know that,arc=theta(angle)*2*Pi*r/360
theta*2*pi*3/360=3*pi/2
pi and 3 cancel on both sides
theta*2/360=1/2
theta/180=2
theta=180/2
Hence theta or the angle required=90 degrees(option C)
