Answer:

$1.6 \times {10}^{1}$

Step-by-step explanation:

$160 \times \frac{1}{10} = \frac{160}{10} = 16$

$16 \: can \: be \: written \: as \: 1.6 \times {10}^{1}$

(Q6) Decide if the function is an exponential function. If it is, state the initial value and the base. y= -4.8·4^x

topjm [15]

Answer:

Step-by-step explanation:

Exponential equation takes the form $y=a*b^x$ where

a is the initial value ( a ≠ 0), and
b is the base ( b ≠ 1)

The equation given in the problem can be written as $y=-4.8*4^x$ , so it is <em>an exponential equation, </em> where a = -4.8 and b = 4.

Thus we can say that the initial value = -4.8 and the base is 4

The correct answer is D

American kestrels live in More Mesa near your professor’s house. Suppose that there are 100 birds, of which a random sample of s

Ulleksa [173]

Answer:

P(X=3) = 0.2013

Step-by-step explanation:

After taking and tagging the first 20 birds, then we have a proportion of 20% of tagged birds within the population, that is

$p=\frac{n}{N}$

$p=\frac{20}{100}=0.20$

Supposing that the probability (0.20) of capturing a bird <em>remains constant</em>, we may resolve it as it follows:

Capturing 10 birds can be considered as a binomial experiment with a success probability p = 0.2

Let, $P(X=x)=nCx*p^{x}*(1-p)^{n-x}$ be the expression of the binomial distribution, for our case we have:

p=0.2

x = 3

n=10

Then,

$P(X=3)=10C3*0.2^{3}*0.8^{10-3}$

$P(X=x)=0.2013$

Therefore, the probability that exactly 3 of the 10 birds in the new sample were previously tagged is 20.13%

Mei Mei invested $1700 in an account that pays 3% interest compounded annually.

algol [13]

Answer:

$2728

Step-by-step explanation:

Use compound interest formula:

$A = P(1 + \frac{r}{n})^{nt}$

P = 1700, r = 0.03, n = 1, t = 16

Plug in numbers:

$A = 1700(1 + \frac{0.03}{1})^{(1)(16)}$

Simplify:

$A = 1700(1.3)^{16$

Use calculator:

$A = 2728$
