Answer:

The correct answer is 10+6p

Step-by-step explanation:

The mistake is that for the first step instead of distributing 2 to 3p and 1 they added 8+2 first. your actually supposed to distribute and get, 8+6p+2, then combine like terms and get 10+6p

Which function has the greatest rate of exponential growth?

Veronika [31]

Answer:

Step-by-step explanation:

Here, we want to find which of the expressions have the greatest rate of exponential growth.

The easiest way to go about this is have a substitution for the term t;

Let’s say t = 6

Thus;

h(t) = 1.18^1 = 1.18

K(t) = 0.375^6 = 0.002780914307

f(t) = 1.36^6 = 6.327518887936

g(t) = 0.86^6 = 0.404567235136

Another way to find this is to express each as a sum of 1

f(t) = (1+ 0.36)^t

g(t) = (1-0.14)^t

k(t) = (1-0.625)^t

We can see clearly that out of all the terms in the brackets asides 1, 0.36 is the biggest in value

Use the data set to answer the question. {22,26,28,35,45,63,91} What is the mean absolute deviation (MAD) of the data set? Enter

shtirl [24]

Answer:

mean absolute deviation is 18.85

Step-by-step explanation:

Step 1:-

Given observation values 22,26,28,35,45,63,91

$mean (x ) = \frac{22+26+28+35+45+63+91}{7}$

mean = 44.28≅ 44

Step2:-

The deviations of the respective observations from the mean (x)

That is $x_{i}-x$

22-44, 26-44,28-44,35-44,45-44,63-44,91-44

-22, -18 ,-16 ,-9, 1, 19, 47

Step 3:-

The absolute values of the given data

$x_{i}-x$

modulus of all these values

22,18,16,9.1,19,47

Step 4:-

Mean absolute deviation M.D=∑ $\frac{x_{i} - x }{n}$

$MAD = \frac{22+18+16+9+1+19+47}{7}$

on simplification we get mean absolute deviation is 18.85
