Delicious77 [7]

the fees in 1997 was $3088

fees in 2000 was $3292

average rate of increase= (3292-3088)/(2000-1997) = 204/3=68

so average rate of increase is $68 per year

Answer:

$P(A\textrm{ and }B)=\frac{3}{14}$

Step-by-step explanation:

Given:

$P(A)=\frac{4}{7}$

$P(B|A)=\frac{3}{8}$

We know that, conditional probability of B given that A has occurred is given as:

$P(B|A)=\frac{P(A\cap B}{P(A)}$ . Expressing this in terms of $P(A\cap B)$ , we get

$P(A\cap B)=P(B|A)\times P(A)$

Plug in the known values and solve for $P(A\cap B)$ . This gives,

$P(A\cap B)=P(B|A)\times P(A)\\P(A\cap B)=\frac{3}{8}\times \frac{4}{7}\\P(A\cap B)=\frac{12}{56}=\frac{3}{14}$

Therefore, the probability of events A and B occurring is $\frac{3}{14}$ .

The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri

vlada-n [284]

Option B: 256 is the diameter of the bacteria after 8 hours.

Explanation:

From the given, it is obvious that the graph is an exponential function.

The general formula is given by,

$y=a(b)^x$

Where a is the initial population,

b is the growth rate and

x is the number of hours.

It is given that the diameter of the bacteria doubles every hour.

Then, we have,

$b=2$

Let us substitute the coordinate (0,1) and $b=2$ , we get,

$1=a(2)^0$

$1=a$

Thus, substituting $a=1$ and $b=2$ in the general formula $y=a(b)^x$ , we have,

$y=1(2)^x$

We need to determine the diameter of the bacteria after 8 hours.

Let us substitute x = 8 in the equation $y=1(2)^x$ , we get,

$y=1(2)^8$

$y=1(256)$

$y=256$

Thus, the diameter of the bacteria after 8 hours is 256

Hence, Option B is the correct answer.

Find the equation of the line with a slope of − 1/2 through (4, 5)

STALIN [3.7K]

Answer: Hello:

Slope - intercept form is y = mx + b.

Since -1/2 is your slope and 5 is your y - intercept, all you need to do is substitute those values into the equation:

y = -1/2 + 5

Hope this helps!
