Answer:

  • 4.3

Step-by-step explanation:

<u>Use cosine:</u>

  • cos = adjacent / hypotenuse
  • cos ∠L = KL/JL
  • cos 21° = 4/x
  • x = 4 / cos 21°
  • x = 4.3 (rounded)

Answer:

  • 4.3

Step-by-step explanation:

Here we will use cosine to find the value..

<h3>\cos =  \frac{adjacent}{hypotenuse}</h3><h3>\cos∠l =  \frac{kl}{jl}</h3><h3>\cos21° =  \frac{4}{x}</h3><h3>x =  \frac{4}{ \cos21° }</h3><h3>x = 4.3 When rounded off...</h3>

Write an equation of the line with slope 2/3 that goes through the point -2,5
irinina [24]

Answer:

y = 2/3x + 19/3

Step-by-step explanation:

First, this is your current equation: y = 2/3x + b. Plug in your point to the equation, it should look like this: 5 = 2/3(-2) + b. 2/3 times -2 equals -4/3. So, this is what your equation should look like: 5 = -4/3 + b. Add 4/3 to both sides of the equation to get 19/3 = b. Go back to your original equation and plug 19/3 to b. This is your final equation: y = 2/3x + 19/3. Hope this helped!

Identify the area of the trapezoid.
Vlad1618 [11]

Option B: The area of the trapezoid is 157.5 m²

Explanation:

We need to determine the area of the trapezoid.

The area of the trapezoid can be determined by the formula,

Area=\frac{h}{2} (a+b)

where h is the height, a and b are the base of the trapezoid.

From the figure, it is obvious that a=14 , b=7 and h=15

Substituting these values in the formula, we have,

Area=\frac{15}{2} (14+7)

Simplifying the terms, we have,

Area=\frac{15}{2} (21)

Multiplying the terms in the numerator, we have,

Area=\frac{315}{2}

Dividing, we get,

Area= 157.5 \ m^2

Thus, the area of the trapezoid is 157.5 m²

Hence, Option B is the correct answer.

Suppose that events a and b are mutually exclusive with p(a) = ½ and p(b) = ⅓.
irina1246 [14]
No, a & b are not independent if they're mutually exclusive.

Mutually exclusive means the two events cannot occur simultaneously. So if "a" happens "b" cannot. In contrast, two events are independent if the occurrence of one has no effect on the occurrence of the other.
