Answer: P (4 or even) = 1/2 = 50% = 0.5
Step-by-step explanation:
Concept:
Here, we need to know the idea of probability.
Probability is a measure of the likelihood of an event to occur.
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
The numbers on a dice: 1, 2, 3, 4, 5, 6
Total numbers: 6
Numbers of 4 = 1
Numbers of even = 3
[Since 4 is one of the even numbers and they are overlapping, so we should subtract 1 from the number of favorable outcomes]
P (4 or even) = Favorable / Total (refer to attachment)
P (4 or even) = [(1 + 3) - 1] / 6
P (4 or even) = (4 - 1) / 6
P (4 or even) = 3 / 6
P (4 or even) = 1 / 2
Hope this helps!! :)

To solve this equation , we need to write it in quadratic form
To get the equation in quadratic form we replace x^2 with u
can be written as
, Replace u for x^2
So equation becomes
Now we factor the left hand side
-16 and -1 are the two factors whose product is +16 and sum is -17
(u-16) (u-1) = 0
u -16 = 0 so u=16
u-1 =0 so u=1
WE assume u = x^2, Now we replace u with x^2
Now take square root on both sides , x= +4 and x=-4
Now take square root on both sides , x= +1 and x=-1
So zeros of the function are -4, -1, 1, 4
The answer Is C: SAS Congruence Postulate.
(1)4x + 3> 15 or -6x>=12
4x+3>15, subtract 3 on both sides (4x> 12) and then divide both sides by 4
x > 3
-6x>=12, divide both sides by -6 , so x<=-2
x>3 or x<=-2
The middle graph satisfies the above inequality
(2) -8x>-24 and -10<=2x-6
-8x>-24 , divide both sides by -8 , so it becomes x < 3
-10<=2x-6, add both sides by 6 , -4<=2x . then divide both sides by 2
x >=-2
x>-2 and x<3
The last graph satisfies the above inequality
-29<=9x-2<16
Add both sides by 2 and then divide both sides by 9
-27 <= 9x < 18
divide both sides by 9
-3 <= x < 2
x lies between -3 and 2
The first graph satisfies the above inequality
