First, you would multiply $210 by 20%
This is done by converting 20% to a decimal, .2
So, 210 • .2 = 42
Then to find the sale price, you would subtract that 42 that you just got from 210,
and you get $168 as the final sale price.
Answer:
a) It can be used because np and n(1-p) are both greater than 5.
Step-by-step explanation:
Binomial distribution and approximation to the normal:
The binomial distribution has two parameters:
n, which is the number of trials.
p, which is the probability of a success on a single trial.
If np and n(1-p) are both greater than 5, the normal approximation to the binomial can appropriately be used.
In this question:

So, lets verify the conditions:
np = 201*0.45 = 90.45 > 5
n(1-p) = 201*(1-0.45) = 201*0.55 = 110.55 > 5
Since both np and n(1-p) are greater than 5, the approximation can be used.
Answer:
C
Step-by-step explanation:
A =
r²
so we do
5² = 25 * 
25 * 
= 78.5 square units
Answer:
Step-by-step explanation:
What i would do is multiply both sides by 2z + 1
so you get z-6=20z+10
-19z=16
z=-16/19
<span>To solve for the given, </span>40, 800 ÷ 10 in unit form and standard form
<span>in unit form and standard form </span>
<span>We can first standardize the given into a equation form which will be: </span>
<span>1. 40,800 / 10 which yield 4,080 </span>
<span>40,800 x 10 = 4080 </span>
<span>Notice the amount of zero the value of 40,800 decreased. </span>
<span>2. The standard form then is 4080 </span>
<span>3. The word form of the quotient is four thousand eighty..<span>
