Answer:

$P(X\geq 2) = 0.375$

Step-by-step explanation:

Given

X ------0 --------1 -------- 2--------- 3

P(X) --.1875 -.4375 ---.3125 --- .0625

Required

Determine $P(X\geq 2)$

This is calculated as:

$P(X\geq 2) = P(X = 2) + P(X = 3)$

$P(X\geq 2) = 0.3125 + 0.0625$

$P(X\geq 2) = 0.375$

"EXPLAIN PLEASE" Which equation does the graph below represent

ch4aika [34]

The answer to your problem is A due to the slope of your line being -1/3x.

You can find this slope by picking two points on your graph [i.e. (-1,3) and (0,0)].

Find the difference between the two points, which is a one for the x value and a three for the y values. Now you have a slope of 1/3.

But wait! The slope is downwards, therefore a negative must be applied to your slope.

This provides you with a slope of -1/3x, therefore:

y = -1/3x

John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21 About how far does

Agata [3.3K]

Answer:

John ski down the mountain is 1285.37 feet.

Step-by-step explanation:

Given : John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21.

To find : About how far does John ski down the mountain ?

Solution :

We draw a rough image of the question for easier understanding.

Refer the attached figure below.

According to question,

Let AB be the height of mountain i.e. AB=1200 feet

The angle of depression is 21 i.e. $\theta=21^\circ$

We have to find how far does John ski down the mountain i.e. AC = ?

Using trigonometric,

$\cos\theta = \frac{AB}{AC}$

$\cos(21)= \frac{1200}{AC}$

$AC=\frac{1200}{\cos(21)}$

$AC=1285.37$

Therefore, John ski down the mountain is 1285.37 feet.
