Do you mean this:

The growth rate is exponential, it doubles every time interval. So by the time you have one bottle, after the next interval you have 2, 4 and so forth.

Answer:

0.6 is the required probability.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 250

Probability of accessing internet at work = 37%

$P(W)=0.37$

Probability of accessing internet at home = 44%

$P(H)=0.44$

Probability of accessing internet at work and home = 21%

$P(W\cap H)=0.21$

We have to evaluate the probability that a person in this sample accesses the internet at home or at work.

$P(H\cup W) = P(H) + P(W) - P(W\cap H)\\P(W\cup H) = 0.37 + 0.44-0.21\\P(H\cup W) = 0.6$

Thus, 0.6 is the probability that a person in this sample accesses the internet at home or at work

What is the area of a sector when r = 2 and 0 = 1.75 radians? [?] sq units Round your answer to the nearest tenth. Enter

krok68 [10]

Answer:

Step-by-step explanation:

The area of a sector in terms of radians as opposed to degrees is

$A=\frac{\theta}{2\pi }*\pi r^2$

Filling in the formula accordingly gives us

$A=\frac{1.75rad}{2\pi rad}*\pi (2)^2$

The radians cancel out, the pi's cancel out, the 2 in the denominator cancels out (divides into 2-squared once), leaving us with

A = 1.75(2) so

A = 3.5 units squared
