Answer:
Complete Table:
Result of Roll ------ Frequency ------- Experimental Probability
1 --------------------------- 22 ------------------- 0.176
2 --------------------------- 13 ------------------- 0.104
3 --------------------------- 18 ------------------- 0.144
4 --------------------------- 29 ------------------- 0.232
5 --------------------------- 37 ------------------- 0.296
6 --------------------------- 6 ------------------- 0.048
Step-by-step explanation:
Required: Complete the table
The table is divided into 3:
1. Result of Roll
2. Frequency (F)
3. Experimental Probability (P)
The relationship between (2) and (3) is:
[tex]P = \frac{F}{N}[/tex]
Where
N = Number of Rolls
N = 125
For Roll of Result = 2
Frequency = 13
The probability is calculated as thus:
[tex]P = \frac{13}{125}[/tex]
[tex]P = 0.104[/tex]
For Roll of Result = 3
Probability = 0.144
The Frequency is calculated as thus:
[tex]0.144 = \frac{F}{125}[/tex]
[tex]F = 0.144 * 125[/tex]
[tex]F = 18[/tex]
For Roll of Result = 4
Frequency = 29
The probability is calculated as thus:
[tex]P = \frac{29}{125}[/tex]
[tex]P = 0.232[/tex]
For Roll of Result = 5
Probability = 0.296
The Frequency is calculated as thus:
[tex]0.296 = \frac{F}{125}[/tex]
[tex]F = 0.296* 125[/tex]
[tex]F = 37[/tex]
For Roll of Result = 6
Frequency = 6
The probability is calculated as thus:
[tex]P = \frac{6}{125}[/tex]
[tex]P = 0.048[/tex]
For Roll of Result = 1.
To get the frequency; we subtract the sum of frequencies of roll of results 2 to 6 from the total number of rolls.
In other words:
Frequency of 1 = Total Rolls - (Frequency of 2 + Frequency of 3 + Frequency of 4 + Frequency of 5 + Frequency of 6)
Frequency of 1 = 125 - (13 + 18 + 29 + 37 +6)
Frequency of 1 = 125 - 103
Frequency of 1 = 22
The probability is calculated as thus:
[tex]P = \frac{F}{N}[/tex]
[tex]P = \frac{22}{125}[/tex]
[tex]P = 0.176[/tex]

Step-by-step explanation:
The straight line L has equation y = 2x - 5
Find an equation of the straight line perpendicular to L which passes through (-2, 3).
Answer:
slope of perpendicular line - m = -1/2
passing through (-2,3)
thus,
y-3 = -1/2 (x+2)
or y = -1/2x +2
An equation of the straight line perpendicular to [tex]\boldsymbol{y=2x-5}[/tex] which passes through [tex]\boldsymbol{(-2,3)}[/tex] is [tex]\boldsymbol{x+2y-4=0}[/tex]
An equation of a straight line is [tex]\boldsymbol{y=2x-5}[/tex]
Compare this equation with the form [tex]\boldsymbol{y=mx+b}[/tex] where [tex]\boldsymbol{m,b}[/tex] denote slope and [tex]\boldsymbol{y-}[/tex]intercept respectively.
So,
[tex]\boldsymbol{m=2}[/tex]
As the slopes of two perpendicular lines are negative reciprocals of each other, slope of a required line is equal to [tex]n=\frac{-1}{2}[/tex]
Take [tex](x_1,y_1)=(-2,3)[/tex]
Equation of the required line is [tex]\boldsymbol{y-y_1=n(x-x_1)}[/tex]
[tex]y-3=\frac{-1}{2}(x+2)[/tex]
[tex]2y-6=-1(x+2)[/tex]
[tex]x+2y-4=0[/tex]

If zeina has seven times as many books as ali if zeina gave ali 15 books they would eash have the same number of books how many books did each have
Answer:
Zeina had 35 books and Ali had 5 books
Step-by-step explanation:
Equations
We know Zeina has seven times as many books as Ali. If we call
x = Number of books Ali has
Then Zeina has
7x = Number of books Zeina has
We also know if Zeina gave Ali 15 books, they would have the same number of books, thus:
x + 15 = 7x - 15
Adding 15:
x + 15 +15 = 7x
Subtracting x:
15 +15 = 7x - x
Operating:
30 = 6x
Dividing by 6:
x = 30 / 6
x =5
7x = 35
Thus Zeina had 35 books and Ali had 5 books
