Step-by-step explanation:
The slope of a line is Change in y
--------------------
change in x
y does not change
0
------
change in x
Slope = 0
Horizontal lines have 0 slope
Vertical lines have undefined slope
Answer:
Step-by-step explanation:
Hope this helps!
Step-by-step explanation:
put the value of y and get the value of x.then plot it in graph.(try to get non fractional values)
Answer:
X=40°
X=30°
X=50°
Step-by-step explanation:
Let our unknown angles be denoted by
Part I
We are given the sum of the angles as 70°, the known as 30° and the unknown as X;
To find X, we subtract the known angle from the sum as:
X=70°-30°=40°
Hence X= 40°
Part II
We are given the sum of the angles as 70°, the known as 40° and the unknown as X;
To find X, we subtract the known angle from the sum as:
X=70°-40°=30°
Hence X= 30°
Part III
We are given the sum of the angles as 80°, the known as 30° and the unknown as X;
To find X, we subtract the known angle from the sum as:
X=80°-30°=50°
Hence X= 50°
13 spades, 52 cards total
probability of drawing a single spade = 13/52 = 1/4
If we replace that card, then the probability of drawing of drawing a spade is still 1/4 as nothing has changed
Overall, the probability of getting two spades in a row is (1/4)*(1/4) = 1/16
note: the two events are independent because of the replacement happening
---------
The answer as a fraction is 1/16
As a decimal, that would be 0.0625 which converts to 6.25%
