I do believe it is -65d because the equation will look like this in the end
-65d=-65d.
X -length
y wide
x=4y
2x+2y=12,5
x=4y
8y+2y=12,5
x=4y
y=1,25
x=5
y=1,25
area
x*y=5*1,25=6,25
Answer:
There's 21% of chances
Step-by-step explanation:
Here we have to use the definition of a simple probability, where all fishes has the same probability to be chose.
So, we have to divide the possible outcomes with the total of outcomes. The possible outcomes refer to the number of large-blue fishes, and the total number of outcomes represent the total number of fishes. So
P = 3/4 ≈ 0.21 (or 21%)
Therfore, there's 21% of chances to select one fish randomly and be a large, blue fish.
We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the following exponential function: 
where y represents the car's value and t represents time in years. We are asked to find the decay rate as a percentage.
We know that an exponential decay function is in form 
, where,
y = Final value,
a = Initial value,
r = Decay rate in decimal form,
x = time.
Upon comparing our given function with standard decay function , we can see that 
.
Let us solve for r.
Let us convert 0.24 into percentage.
Therefore, the decay rate is 24%.
