1. The total area within any continuous probability distribution is equal to 1.00.

Mathematics

olchik [2.2K]3 years ago
5 0

Answer:

1. True

2. False.

3. True.

Step-by-step explanation:

1. The total area within any continuous probability distribution is equal to 1.00: it is true because the maximum probability (value) is one (1), therefore, the total (maximum) area is also one (1).

<em>Hence, for continuous probability distribution: probability = area</em>.

2. For any continuous probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: False because it has an infinite number of possible values, which can not be counted or uncountable.

<em>Hence, it cannot be computed. </em>

3. For any discrete probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: True because it has a finite number of possible values, which are countable or can be counted.

<em>Hence, it can be computed. </em>

Which graph represents the solution set to this system of equations? –x + 2y = 6 and 4x + y = 3 On a coordinate plane, a line go
erastova [34]

Answer:

On a coordinate plane, a line goes through (0, 3) and (2, 4) and another line goes through (0, 3) and (0.75, 0).

This answer almost coincide with option C. I suppose there was a mistype.

Step-by-step explanation:

The system of equations is formed by:

–x + 2y = 6

4x + y = 3

In the picture attached, the solution set is shown.

The first equation goes through (0, 3) and (2, 4), as can be checked by:

–(0) + 2(3) = 6

–(2) + 2(4) = 6

The second goes through (0, 3) and (0.75, 0), as can be checked by:

4(0) + (3) = 3

4(0.75) + (0) = 3

If f(x)=7x-7 what is f(8)+f(4)
NARA [144]

<u>Given Function is</u>

  • f ( x ) = 7x - 7 ------- eqn ( 1 )

<u>Now , put the value of x = 8 in eqn ( 1 )</u>

  • f ( 8 ) = 7 ( 8 ) - 7
  • f ( 8 ) = 56 - 7
  • f ( 8 ) = 49 ------- eqn ( 2 )

<u>Now , put the value of x = 4 in eqn ( 1 )</u>

  • f ( 4 ) = 7 ( 4 ) - 7
  • f ( 4 ) = 28 - 7
  • f ( 4 ) = 21 ------- eqn ( 3 )
<h3 />

<u>From eqn ( 2 ) nd eqn ( 3 ) we get,</u>

  • f ( 8 ) + f ( 4 )
  • 49 + 21
  • 70

Hope Helps! :)

Triangle ABC has vertices at A(3, 8) , B(11, 8) , and C(9, 12) . Triangle FGH has vertices at F(1, 3) , G(9, 3) , and H(7, 7) .
Alex17521 [72]
Hmm, (x,y)
x is horizontal or left right
y is vertical or up down


so

we see that A to F is move left 2 and down 5
B to G is left 2 and down 5
C to H is left 2 and down 5


so translatete ABC left 2 and down 5 and
translate FGH right 2 and up 5

not 1st option
2nd works
3rd works
4th is false


2nd and 3rd
