In the spinner there are eight numbers numbered from 1 to 8.
To solve this problem, we must remember that probability is:
Probability = number of successful events / number of total
events
a. P (even number). There are 4 even numbers, therefore the
probability is:
P (even number) = 4 / 8
P (even number) = ½ = 0.5 = 50%
The probability of getting an even number is 50%.
b. P (a number greater than
3). There are 5 numbers greater than 3, therefore the probability is:
P (number greater than 3) = 5
/ 8
P (number greater than 3) = 0.625
= 62.50%
The probability of getting a number greater than 3 is 50%.
c. P (an odd number). Similar
to the even number, there are 4 odd numbers. Therefore,
The probability of getting an odd number is 50%.
I not sure if you mean the gradient of the line or the equation, so here is both.
Gradient (=m) :
( 4, 4 ) ( 6, 5 )
( x1 , y1) ( x2, y2 )
m = y2-y1 / x2-x1
= -5-4 / 6 - 4
= -9 / 2 (as a fraction)
= -4.5 (as a decimal)
Equation of the line :
m = -9/2
( 4, 4 )
( a, b )
y - b =m (x - a)
y - 4= -9/2 (x - 4)
(Multiply both sides by 2 to get rid of fraction)
2y - 4 = -9 (x - 4)
2y - 4 = -9x + 36
2y = -9x + 36 + 4
2y = -9x + 40
2y + 9x = 40
Please feel free to ask if you have any questions
|3x|=9
3x=9 -3x=9
X=9/3 x=9/-3
x=3 x=-3
Whenever you have an absolute value sign you have to find both the positive and the negative because they didnt signs into the equation but sometimes a question will ask for strictly the positive value or the negative value but if its not stated, find both.
