What is m<KNL? <br>Enter your answer in the box<br>

steposvetlana [31]

The measurement of ∠KNL is 102°

First, you must set up an equation to find x.

$5x+2=[3(x+14)$

Then, you must simplify both sides of the equation.

$5x+2=3x+42$

Next, subtract 3x on both sides.

$2x+2=42$

Then, subtract 2 on each side.

$2x=40$

Next, divide 2 on each side.

$x=20$

Now that we have the value of x, we can substitute it in for angle KNL.

$[3(20+14)]$

$[3(34)]$

$102$

$102$ °

Describe the relationship between the area of a circle and its circumstances

valentina_108 [34]

Answer:

$A = \frac{r}{2}C$

Step-by-step explanation:

Given

Shape: Circle

Required

The area and the circumference (relationship)

This implies that, we write an expression that relates the area and the circumference.

Circumference is calculated as:

$C = 2\pi r$

Area is calculated as:

$A = \pi r^2$

The area can be rewritten as:

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

Further rewrite as:

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

Recall that: $C = 2\pi r$

So, the expression becomes

$A = \frac{r}{2}*C$

$A = \frac{r}{2}C$

Let's consider the time as a discrete variable with an increment of 1 minute. You arrive at a bus stop at 10 AM, knowing that th

Dafna11 [192]

Answer:

a) 2/3

b) 1/3

Step-by-step explanation:

Let X be the random event that measures the time you will have to wait.

Since time is uniformly distributed between 10 and 10:30 in intervals of 1 minute

P(n < X ≤ n+1) = 1/30 for every minute n=0,1,...29.

a)

P( X > 10) = 1 - P(X ≤ 10) = 1 - 10/30 = 2/3

b)

P(10 < X ≤ 20) = (20-10)/30 = 1/3
