Let A be the event A=\{choosing \;an \;odd \;number\} and B be the vent B=\{choosing \;an \;even \;number\}. Since the intersection of the events A\cap B=\phi, the events A and B are mutually exclusive.

The number is either odd or even. Since P(A)+P(B)=1, the events are mutually exclusive and exhaustive.

Correct choice is "the number is either odd or even".

Given the following points, write the equation of the line that goes through them. ( -12,56), (0,8), and (8,-24).
BaLLatris [955]

Answer:

y=-4x+8

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

take two points from the data

(0,8), and (8,-24).

substitute

m=\frac{-24-8}{8-0}

m=\frac{-32}{8}

m=-4

step 2

Find the equation of he line in slope intercept form

y=mx+b

we have

m=-4

b=8 ----> the y-intercept is given

substitute

y=-4x+8

Solve for the value of y.<br> 60°<br> (8y-2)
rusak2 [61]
Since it's a right angle the sum of the two angles equals 90°
(8y-2)°+60°=90°
8y-2=90-60
8y-2=30
8y=30+2
8y=32
y=32/8
y=4

The value of c is equal to _____.
DENIUS [597]

For this case we have that by definition, the Pythagorean theorem states that:

c = \sqrt {a ^ 2 + b ^ 2}

Where:

a, b: Are the legs

c: It is the hypotenuse

According to the figure we have to:

a = 20\\b = 21

Substituting in the formula we have:

c = \sqrt {(20) ^ 2 + (21) ^ 2}\\c = \sqrt {400 + 441}\\c = \sqrt {841}\\c = 29

Answer:

Option D
