X*80+y*60= 50*74
x +y =50 | * ( -60)
80x + 60y= 50*74
-60x - 60y=-50*60
---------------------------
20x= 50*(74-60)=50*14
x=50*14/20=35 pounds of 80 cents tea
y=50-35=15 pounds of 60 cents tea
Answer:
The equation for the amount of salary after x number of years is given by:
where
a is the initial amount
x represents the number of years and
r represents the growth rate( in decimal)
As per the statement:
You begin your first day as a police officer earning $30,000/yr
⇒ a= 30,000
It is also given that you obtain a full 5% increase each year,
⇒
then;
....[1]
we have to find the salary in three years.
⇒
Substitute this value in [1] we have
Simplify:
therefore, your salary be in three years will be $34,4728.75
hey thanks for the point's i really needed them.. Cheers!
many
Precision is a measure of how close a value is to the
ideal value. In this case, we calculate the difference to know what is the
closest to 4 g:
4.05 – 4 = 0.05
3.98 – 4 = -0.02
4.021 – 4 = 0.021
We can see that the value of 3.98g has the lowest
difference and is therefore the closest to 4g. Hence the most precise is:
<span>3.98 g</span>
if the number of times spun is not a multiple of 8, it is impossible to land on an exactly even distribution for this spinner. But since the probabilities of landing on an exactly even distribution are so small, that detail doesn't perturb the overall trend, except perhaps down at n=8 spins So group 3
