To find 10% you divide the amount by 10 so £1.80 dived by 10 is 0.18p. Therefore you want 10% OFF that amount so you do £1.80-0.80p and you are left with £1.00.
Answer:
As long as the sample size n is large enough: The average IQ of Americans in the sample will be normally distributed.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation 
So the correct answer is:
As long as the sample size n is large enough: The average IQ of Americans in the sample will be normally distributed.
The first thing we must do for this case is to define the variables:
x = the amount earned
y = the money saved
The equation of the line that adapts to this problem is given by:
y = (1/5) x
Let's check:
For x = 20 $ we have:
y = (1/5) (20)
y = 4 $
Answer:
The slope of Mike's graphed line will be:
B) 1/5
Answer:
242.
Step-by-step explanation:
C = 0.03 x 2 − 8 x + 700
When the marginal cost = $522 we have:
522 = 0.03 x 2 − 8 x + 700
0.03x^2 - 8x + 700 - 522 = 0
0.03x^2 - 8x + 178 = 0
Using the quadratic formula:
x = [ -(-8) +/- sqrt( 64 - 4 * 0.03 * 178)] / 0.06
= 8 +/- sqrt42.64 / 0.06
= 242 players.
