1/11 is the probability
Explanation: Their are 11 letters in the word probability and your choosing one letter out of the eleven other letters.
Answer:
(2,10) and (10,90)
Step-by-step explanation:
First: Find the slope
Formula for Finding Slope
Plug in the values (1,0) and (5, 40) in the formula
=
= 10
Slope = 10
Second Step: Find the y-intercept
Slope-Intercept Form Formula: y = mx + b
mx is the slope and b is the y-intercept
0 = 10(1) + b
0 = 10 + b
b = -10
Third Step Plug in the values
x-value is 2
y = 10(2) - 10
y = 20 - 10
y = 10
y-value = 10
y-value is 90
90 = 10x - 10
90 + 10 = 10x - 10 + 10
10x = 100
x = 10
7(3a + 12) = 168 ← ( divide both sides by 7 )
3a + 12 = 24 ← ( subtract 12 from both sides )
3a = 12 ← ( divide both sides by 3 )
a = 4
OR
distribute the parenthesis by 7
21a + 84 = 168 ← ( subtract 84 from both sides )
21a = 84 ← ( divide both sides by 21 )
a = 4
