Answer:
r = 5
Step-by-step explanation:
(r + 8)^2 = r^2 + 12^2
r^2 + 16r + 64 = r^2 + 144
16r = 80
r = 5
Answer:
And we can find this probability with this difference
And we can see the figure in the plot attached.
Step-by-step explanation:
Let X the random variable that represent the redings on thermometers of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
We can use the z score formula given by:
Using this formula we got:
And we can find this probability with this difference
And we can see the figure in the plot attached.
Answer:
y = ($2500)(1.04)^x
Step-by-step explanation:
The initial value = $2500
The value of the stock is expected to grow at the rate of 4%
Let x represent the number of years since the stock was made available for purchase.
Let y represent the value of the stock x years later.
y1 = amount of money after one year.
y1 = $2500 (100% + 4%)
y1 = $2500 (104%)
y1 = $2500(1.04)
y2 = amount of money after two years
y2 = y1 (100% + 4%)
y2 = y1 (104%)
y2 = y1(1.04)
y2 = $2500(1.04)(1.04)
y2 = $2500(1.04)^2
This will give a pattern
y5 = $2500(1.04)^5
After x years the model of the equation will be y = ($2500)(1.04)^x
