The answer is "c. continuous probability distribution."

"Continuous" means it is a subset of the real numbers set: it can take any value in a specified range. For example, if you break at random a stick with a given length of 12 cm, and then measure the shortest piece, you can get any value in the range (0 cm, 6 cm). This is a continuous random variable.

A random variable is said to be "discrete" if it can only take values from a finite (or countably infinite) set. For example, if you roll a dice, you can get only 1, 2, ..., 6. But you cannot get any vaue in the range [1, 6], because the value must be an integer (e.g., you cannot get the vaue 2.5). This is a discrete random variable.

A somewhat technical explanation:

- A random variable is a mapping from a event space to a number set: it associates a number (a value of the variable) with every event.

- The random variable is said to be continuous if it maps events to numbers from a subset of the set of real numbers.

- The probability distributions corresponding to continuous random variables are called continuous probability distributions.

The three angles of a triangle measure 2x – 6, 3x + 5, and 2x + 20. What is the measure of the smallest angle in degrees
Radda [10]

Answer:

Smallest angle = 40

Step-by-step explanation:

Angle sum property:Sum of all three angles of triangle is 180

2x - 6 + 3x + 5 + 2x + 20 = 180   {Combine like terms}

2x + 3x + 2x - 6 + 5 + 20 = 180

                     7x  + 19       = 180            {Subtract 19 from both sides}

                                  7x = 180 - 19

                                  7x = 161               {Divide both sides by 7}

                                    x = 161/7

x = 23

2x - 6 = 2*23 - 6 = 46 - 6 = 40

3x + 5 = 3*23 + 5 = 69 + 5 = 74

2x + 20 = 2*23 + 20 = 46 + 20 = 66

Smallest angle = 40

Uhhh I am struggling with this question algebra 1
Olin [163]

Answer:

-2x^2 +16x -8

Step-by-step explanation:

Oh s-

Like terms i guess Same variable you can substract. Remember you only substract from 1 number not from all.

-2x^2 stays the same as there is no like term

9x - (-7x)

-2 - (6)

-2x^2 + 9x+ 7x -2-6

-2x^2 +16x -8

Vladimir79 [104]

Answer:

6 vans

Step-by-step explanation:

If 1 van can seal 18 students...

116 ÷ 18 = 6.4

Since it's not a whole number, we will estimate it to the nearest whole number which is 6.

igomit [66]

length (l) =54

breath (b) =72

l²+b²= diagonal²..........(Pythagoras theorem) and (all sides of rectangle are 90degree)

(54)²+(72)²=diagonal²

2916+5184=diagonal²

8100=diagonal²

90= diagonal.............(taking square root)

length of diagonal is 90ft

i hope it helps
