A uniform distribution is defined over the interval from 6 to 10.
zhuklara [117]

Answer:

Refer below

Step-by-step explanation:

a) a and b are the lower and higher values of the interval for which uniform distribution is defined.

Here a= 6 and b =10

b) Mean of the uniform distribution= (a+b)/2 = (6+10)/2 =8

Or int x (1/4) dx = x^2/8 = 8

c) Variance of the uniform distribution = (b^2-a^2)/12 = (100-64)/12

= 36/12 =3

Std dev = sq rt of 3 = 1.732

d) To find total area

PDF of the distribution = 1/(b-a) = 1/4, 6<x<10

Area = \int 6 to 10 of 1/4 dx

= x/4

Subtitute limits

= (10-6)/4 =1

So total area = 1

d)P(X>7) = int 7 to 10 of 1/4 dx = 3/4

e) P(7<x<9) = Int 7 to 9 of 1/4 dx = 2/4 = 1/2

Which of the following statements are true?
IgorC [24]

Answer:  statement 2: a square is always a rhombus.

Step-by-step explanation:

A parallelogram does not have all the interior angle as right angle.

Therefore, it does not satisfy property of rectangle.

A square has all sides equal and its diagonals are perpendicular bisector.

Thus,  square satisfies all the properties of rhombus .

A rectangle does not have all the sides are equal.

Therefore, it cannot b e a square.

Pls answer! i will mark brainliest!
Volgvan

Answer:

3 inches

Step-by-step explanation:

(14+2x) × (15+2x) = 2(14×15)

210 +30x +28x + 4x² = 420

4x² + 58x - 210 = 0

2x² + 29x - 105 = 0

2x² + 35x - 6x - 105 = 0

x(2x + 35) - 3(2x + 35) = 0

(x - 3)(2x + 35) = 0

x = 3, -35/2(not possible)

Helppppp meeee plzzzzz

Answer:

∠B = 41°

Step-by-step explanation:

∠BCD is an exterior angle of the triangle

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠A and ∠ B are the 2 opposite interior angles, hence

∠A + ∠B = 113, that is

72 + ∠B = 113 ( subtract 72 from both sides )

∠B = 41°
