Jackson purchases a new car for $48,000. The car's value can be modeled by the

vekshin1

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: $y = 48000(0.76)^t$ 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 $y=a\cdot (1-r)^x$ , where,

y = Final value,

a = Initial value,

r = Decay rate in decimal form,

x = time.

Upon comparing our given function $y = 48000(0.76)^t$ with standard decay function $y=a\cdot (1-r)^x$ , we can see that $1-r=0.76$ .

Let us solve for r.

$1-1-r=0.76-1$

$-r=-0.24$

$r=0.24$

Let us convert 0.24 into percentage.

$0.24\times 100\%=24\%$

Therefore, the decay rate is 24%.

monitta

Answer:

$46,053

Step-by-step explanation:

Convert 29% into a decimal, which is 0.29.
Multiply $35,700 by 29% as a decimal (0.29), which is 10,353.
Since the keyword is more, we want to add $35,700 and 10,353 (29% of $35,700). The answer will be $46,053.

The median of a continuous random variable having distribution function F is that value m such that F(m) = 1/2 . That is, a rand

neonofarm [45]

Answer:

Step-by-step explanation:

To find median and mode for

a) In a uniform distribution median would be

(a+b)/2 and mode = any value

b) X is N

we know that in a normal bell shaped curve, mean = median = mode

Hence mode = median = $\mu$

c) Exponential with parameter lambda

Median = $\frac{ln2}{\lambda }$

Mode =0
