Any answer is correct because when you plug in any number you'll get the same thing on both sides
3x-2=3x-2 (any value can be plugged in for x)

If P(A)=0.54 then what value of P(B) the event A and B are complementary event

aleksley [76]

Answer:

P(B) = 0.46

Step-by-step explanation:

Probability

The complementary event of a given event A is defined as "not A" or the event that A does not occur.

For example, if A is defined as 'getting a job', then the complement of A is 'not getting a job'.

Event A and its complementary event (call it B) must satisfy:

P(A) + P(B) = 1

If we know P(A)=0.54, then

P(B) = 1 - P(A)

P(B) = 1 - 0.54

P(B) = 0.46

What is the distance between (-6,0) and (5,3)?

Dmitriy789 [7]

Answer:

$\sqrt{130}$ or 11.4

Step-by-step explanation:

Use the distance formula:

d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

Plug in the points:

d = $\sqrt{(-6 - 5)^2 + (0 - 3)^2}$

Simplify:

d = $\sqrt{(-11)^2 + (-3)^2}$

d = $\sqrt{121 + 9}$

d = $\sqrt{130}$

= approximately 11.4

So, the distance is $\sqrt{130}$ or approx. 11.4

Which is equivalent to..... algebra II engenuity

katrin2010 [14]

Answer:

The correct answer is second option option

9¹/⁸ ˣ

Step-by-step explanation:

Points to remember

Identities

ᵃ√x = = x¹/ᵃ

√x = x¹/²

(xᵃ)ᵇ = xᵃᵇ

To find the correct option

It s given that,

(⁴√9)¹/² ˣ

By using the above identities we can write,

(⁴√9)¹/²ˣ = (9¹/⁴)¹/²ˣ [ since ⁴√9 = 9¹/⁴]

= 9⁽¹/⁴ * ¹/²⁾ ˣ

= 9¹/⁸ ˣ

Therefore the correct answer is second option option

9¹/⁸ ˣ

Given the coordinates of the vertices of a quadrilateral, determine whether it is a square, a rectangle, or a parallelogram. The

vodomira [7]

Answer:

2) ABCD is a RECTANGLE.

Perimeter = 30 units

Step-by-step explanation:

Here, the given points of the quadrilateral are:

A(6, –4), B(11, –4), C(11, 6), D(6, 6)

Now, if P(a,b) and Q(c,d) are any two given points, then the distance between them is given by DISTANCE FORMULA as:

$PQ = \sqrt{(c-a)^2 + (d-b)^2$

Use this to find the length of all 4 sides:

AB with coordinates A(6, –4), B(11, –4) is given as:

$AB = \sqrt{(11-6)^2 + (-4-(-4))^2} = \sqrt{(5)^2 + 0} = 5$

⇒ AB = 5 units

BC with coordinates B(11, –4), C(11, 6) is given as:

$BC = \sqrt{(11-11)^2 + (6-(-4))^2} = \sqrt{(0)^2 + 10^2} = 10$

⇒ BC = 10 units

CD with coordinates C(11, 6), D(6, 6) is given as:

$CD = \sqrt{(11-6)^2 + (6-6)^2} = \sqrt{(5)^2 + 0} = 5$

⇒ CD = 5 units

AD with coordinates A(6, –4),D(6, 6) is given as:

$AD = \sqrt{(6-6)^2 + (-4-(-4))^2} = \sqrt{(0)^2 + 10^2} = 10$

⇒ AD = 10 units

Now, here AB = CD = 5 units, AD = BC = 10 units

Also, in a RECTANGLE, OPPOSITE SIDES ARE EQUAL IN LENGTH.

Hence, ABCD is a RECTANGLE.

Perimeter = AB + BC+ CD + AD = 5 + 10 + 5 + 10 = 30 units
