Find the slope of the line that passes through the pair of points. (2, 6), (7, 0)

Sergio039 [100]

Answer:

The slope is -6/5

Step-by-step explanation:

You find ur y2 and y1 then set it over your x2 and your x1

that gives you 0-6 / 7-2

that gives you -6/5

An experiment consists of drawing 1 card from a standard 52-card deck. What is the probability of drawing a black 6?

Mrac [35]

1/26

In a standard pack of 52 playing cards there are 2 black 6 's

The 6 of spades and the 6 of clubs

Probability = number of favourable outcomes / number of possible outcomes

P( black 6 ) =2/52 = 1/26 in simplest form

Find x.______________a0

velikii [3]

Answer:

$x=4$

Step-by-step explanation:

Before we find x, we need to set up this triangle a little more. We need to find the triangle's altitude before we can solve for x. We will use the heartbeat method to find the altitude.

Let altitude = y; solve for y:

$\frac{2}{y}=\frac{y}{6}$

$y^2=12$

$y=\sqrt{12}$

$y=2\sqrt{3}$

Now that we know the altitude, we can use the Pythagorean Theorem to find the hypotenuse (x).

$a^2+b^2=c^2$

$2^2+(2\sqrt{3})^2=c^2$

$4+12=c^2$

$c^2=16$

$c=4$

Since c and x are the same; c is just the hypotenuse in the Pythagorean Theorem.

$x=4$

Let the domain of x be the set of geometric figures in the plane, and let Square(x) be "x is a square" and Rect(x) be "x is a re

Musya8 [376]

Answer:

a) The statement is also true, because a square is a geometric figure in the plane and a square is also a rectangle.

b) The statement is also true, because for example a rectangle with length 4 and width 6 is a possible rectangle that is not a square (as the length and the width are unequal).

c) The statement is true, because squares are a specific type of rectangle and thus all squares are rectangles.

Step-by-step explanation:

Negation ~P: not P

Conjunction p ∧ q: p and q

Conditional statement p --> q: if p, then q

Existential statement ∃xP(x) is true if and only one element x in the domain for which P(x) is true.

Universal statement ∀xP(x) is true if and only if P(x) is true for all values of x in the domain.

Domain=set of all geometric figures in the plane

Square(x)="x is a square"

Rect(x)="x is a rectangle"

(a)

∃x such that Rect(x) ∧ Square(x)

∃ mean "there exists"

In words, the given statement then means that: There exists a geometric figure in the plane that is a rectangle and that is a square.

The statement is also true, because a square is a geometric figure in the plane and a square is also a rectangle.

(b)

∃x such that Rect(x) ∧ ~ Square(x)

∃ mean "there exists"

In words, the given statement then means that: There exists a geometric figure in the plane that is a rectangle and that is not a square.

The statement is also true, because for example a rectangle with length 4 and width 6 is a possible rectangle that is not a square (as the length and the width are unequal).

(c)

∀x, Square(x) —> Rect(x)

∀ means "for every".

In words, the given statement means that: All squares are also rectangles.

The statement is true, because squares are a specific type of rectangle and thus all squares are rectangles.

Shea's mother wanted to get him a doctor's bag for a graduation present. She thought it would cost $125, but the actual cost was

Ostrovityanka [42]

So percent error= $\frac{|actual value-predicted value|}{predicted value}$ times 100
note: |x| means absolute value of x means makes it positive

predicted value=125
actual value=95.99
subaitute
$\frac{|95.99-125|}{125}$ times 100= $\frac{|-29.01|}{125}$ times 100= $\frac{29.01}{125}$ times 100= $\frac{2901|}{125}$ =23.208 or about 23%

the answer is 23%
