What is the area of ABC? I need to find out how many units, please help

nikitadnepr [17]

To find the area of this figure, let's first split this into two triangles by drawing a vertical line from point B down to the bottom of the figure. We then have two triangles:

One triangle with a base of 6 units and a height of 6 units
And a second triangle with a base of 1 unit and a height of 6 units

We know that to find the area of a triangle, we must use the equation:

$A= \frac{1}{2}bh$

So let's solve for the first triangle:

$A= \frac{1}{2}(6)(6)=18 units^{2}$

The let's solve for the second triangle:

$A= \frac{1}{2}(1)(6)=3 units^{2}$

Now to find the total area of the figure, let's add them together:

$18units^{2}+ 3units^{2} = 21units^{2}$

Now we know that the area of this figure is $21 units^{2}$ .

17. Northern Airlines has a reputation for being on time 86% of the time.

m_a_m_a [10]

Answer:

85.33% probability that a Northern Airlines plane will be on time for at least four of its next five flights.

Step-by-step explanation:

For each Northern Airlines flight, there are only two possible outcomes. Either it is on time, or it is not on time. The probability of a flight being on time is independent of other flights. So we use 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.

Northern Airlines has a reputation for being on time 86% of the time.

This means that $p = 0.86$

Find the probability that a Northern Airlines plane will be on time for at least four of its next five flights.

$P(X \geq 4) = P(X = 4) + P(X = 5)$

In which

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

$P(X = 4) = C_{5,4}.(0.86)^{4}.(0.14)^{1} = 0.3829$

$P(X = 4) = C_{5,4}.(0.86)^{5}.(0.14)^{0} = 0.4704$

$P(X \geq 4) = P(X = 4) + P(X = 5) = 0.3829 + 0.4704 = 0.8533$

85.33% probability that a Northern Airlines plane will be on time for at least four of its next five flights.

Prove or disprove that (1)/(1-cot x) is the same as (sin x)/(sin x - cos x)

SIZIF [17.4K]

$\dfrac{1}{1-\cot x}=\dfrac{\sin x}{\sin x-\cos x}\\\\L_s=\dfrac{1}{1-\dfrac{\cos x}{\sin x}}=\dfrac{1}{\dfrac{\sin x}{\sin x}-\dfrac{\cos x}{\sin x}}=\dfrac{1}{\dfrac{\sin x-\cos x}{\sin x}}=\dfrac{\sin x}{\sin x-\cos x}=R_s$

$\text{Used:}\\\\\cot x=\dfrac{\cos x}{\sin x}$
