Travka [436]

Answer:

Option D

Step-by-step explanation:

Let an exponential function

$f(x)=ab^x$

Where a=Constant $\neq 0$

$b\neq 0$

We know that

$b^0=1$

Therefore,

Point (0,0) can not be obtained by exponential function.

Hence,option A and C are incorrect.

Substitute (0,1)

$1=a$

$f(x)=b^x$

Substitute (1,2)

$2=b^1$

$\implies b^2=4\neq 5$

Hence, option B is incorrect.

D.(0,1),(1,3),(2,9),(3,27)

$f(1)=b=3$

$b^2=(3)^2=9$

$b^3=3^3=27$

Hence, option D is correct.

Answer:

Sample A Estimate: 330

Sample B Estimate: 420

Sample C Estimate: 360

Median: 360

Range: 90

Step-by-step explanation:

For the sample estimate, multiply 600 by 11/20, 7/10, and 3/5 in order.

600 * 11/20

6600/20

330 people for Estimate A.

600 * 7/10

420/10

420 people for Estimate B.

600 * 3/5

1800/5

360 people for Estimate C.

330, 360, 420

360 is the median of these estimates.

420 - 330 = 90

90 is the range of these estimates.
