There are 4 triangles with base of 5 and height of 8.4

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 5 x 8.4 = 21 m^2

Multiply by 4 = 21 x 4 = 84 m^2

Area of the base = length x width = 5 x 5 = 25 m^2

Total area = 84 + 25 = 109 m^2

Answer:

$P(X = x) = C_{8,x}.(0.4)^{x}.(0.6)^{8-x}$

In which x is the number of which we want to find the probability.

Step-by-step explanation:

For each traffic fatality, there are only two possible outcomes. EIther it involved an intoxicated or alcohol-impaired driver or nonoccupant, or it didn't. Traffic fatalities are independent of other traffic fatalities, which means that the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

The probability is .40 that a traffic fatality involves an intoxication or alcohol-impaired driver or nonoccupant.

This means that $p = 0.4$

Eight traffic fatalities

This means that $n = 8$

Find the probability that the number which involve an intoxicated or alcohol-impaired driver or nonoccupant is

This is P(X = x), in which x is the number of which we want to find the probability. So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = x) = C_{8,x}.(0.4)^{x}.(0.6)^{8-x}$

Holly deposited $10,000 in an investment account. After 6 years the account is worth approximately $13,400. Which formula repres

Nady [450]

Formula for exponential growth is:

A = P(1+r)^t

Where A is the resulting amount, P is the initial value, r is the rate, and t is the time passed.

Filling this out for this situation gets you:

13400 = 10000(1+r)^6

Solving for r:

Divide 13400 by 10000

1.34 = (1+r)^6

Take the 6th root of both sides...
1 + r = 1.05

No more work is needed, since you aren’t solving for r.

Full equation:
V = 10000(1.05)^t
Answer C is correct
