A television game has 6 shows doors, of which the contests must pick 2. behind two of the doors are expensive cars, and behind the other 4 doors are consolation prizes. Find the probability that the contestant wins exactly 1 car? no car? or atleast one car?
Answer:
In this question, there are 4 consolation door and 2 car doors of total 6 doors. That means for the first door the chance to get consolation is 4/6 and car is 2/6. In second door, only 5 remains so the chance to get consolation is either 4/5 (if 1st door car) or 3/5(if 1st door consolation)
Win 1 car condition:
1. 1st door car, 2nd door consolation = 2/6 * 4/5 =8/30
2. 1st door consolation, 2nd door car= 4/6 * 2/5 = 8/30
8/30+8/30= 16/30
No car condition
1. 1st door consolation, 2nd door consolation= 4/6 * 3/5= 12/30
At least one car condition
1. 1st door car, 2nd door car = 2/6 * 1/5 =2/30
2. 1st door car, 2nd door consolation = 2/6 * 4/5 =8/30
3. 1st door consolation, 2nd door car= 4/6 * 2/5 = 8/30
2/30 + 8/30 + 8/30= 18/30

How many numbers are 10 units from 0 on the number line? Type your answer as a numeral.How many numbers are 10 units from 0 on the number line?
Answer:
10 number
Step-by-step explanation:
A number line is a straight horizontal line which shows integers. Center of number line is 0.
Left side of 0 is negative integers or numbers
Right side of 0 is positive integers or numbers
" 10 units from 0 on number line"
It would be either left side or right side.
So, number will be -10 or 10.
Please have a look in attachment for number line.
So, 10 number from 0 on number line either left or right side.

In triangle FGH, GJ is an angle bisector of ∠G and perpendicular to FH.
What is the length of FH?
___ units
we know that
in the right triangle FGJ
[tex]cos(FGJ)=\frac{GJ}{FG}= \frac{GJ}{3x-8}[/tex] ----> equation A
in the right triangle GJH
[tex]cos(JGH)=\frac{GJ}{GH}= \frac{GJ}{16}[/tex] ----> equation B
m∠(FGJ)=m∠(JGH) ------> because GJ is an angle bisector of ∠G
so
equate equation A and equation B
[tex]\frac{GJ}{3x-8}=\frac{GJ}{16}\\ 3x-8=16\\3x=24 \\x=8\ units[/tex]
that means
[tex]FG=3*8-8=16\ units[/tex]
[tex]FG=GH[/tex]-------> the triangle FGH is an isosceles triangle
hence
[tex]FJ=JH\\FJ=8\ units[/tex]
[tex]JH=8\ units[/tex]
[tex]FH=FJ+JH=8+8=16\ units[/tex]
therefore
the answer is
[tex]FH=16\ units[/tex]

graph of the quadratic function f(x)=‒(x+4)(x‒6) is shown on the coordinate grid below.
Which statement is not true?
A.
The maximum of this function occurs when y=25.
B.
The function increases in the interval 1 to 6.
C.
The has a zero at (‒4,0).
D.
The function positive in the interval ‒4 to 6.
Answer:
Option B is not true.
Step-by-step explanation:
The quadratic function is f(x) = -(x + 4)(x - 6)
Now we check each option given
Option A.
It is clear from the graph function is maximum at y = 25.
TRUE.
Option B.
Function increases in the interval 1 to 6.
Let's check this at x = 2 and x = 3
f(2) = -(2 + 4)(2 - 6)
= -(6)(-4)
= 24
f(3) = -(3 + 4)(3 - 6)
= - (7)(-3)
= 21
So we find this function is decreasing in this interval.
So the given option is FALSE.
Option C.
The function has a zero at (-4, 0)
f(-4) = -(-4 + 4)(-4 + 6) = 0
So the function has a zero at (-4, 0).
Option is True.
Option D.
The function is positive in the interval -4 to 6
f(x) = -(x + 4)(x - 6)
f(-3) = -(-3 + 4)(-3 - 6)
= -(1)(-9)
= 9
f(0) = -(0 + 4)( 0 - 6)
= 24
Therefore, this function is positive in this interval so the option is TRUE.
Option B is not true.

Given the number 456789abh, list out its byte value in little-endian order
The little-endian byte value of 456789abh is 0xab896745, listed in reverse order of its hexadecimal representation.
To represent the number 456789abh in little-endian byte order, we break it into bytes (8 bits each) and reverse their order:
456789abh = 0x456789ab
In little-endian order:
- 0xab
- 0x89
- 0x67
- 0x45
So, the little-endian byte value of 456789abh is 0xab896745.

At the beginning of a bake sale mary set aside 4 pies for herself karen bought half of the remaining pies for her birthday party and 5 more pies were sold during the sale. When the sale was over there were 19 pies remaining. How msny pies were there before the bake sale started
There were 52 pies before the bake sale started as per the provided condition.
Let's break down the information given step by step:
At the beginning of the bake sale, Mary set aside 4 pies for herself. So, the number of remaining pies is the total number of pies minus 4.
Karen then bought half of the remaining pies for her birthday party. This means the number of remaining pies is now half of the previous remaining pies.
Next, 5 more pies were sold during the sale. Therefore, the number of remaining pies is further reduced by 5.
Finally, when the sale was over, there were 19 pies remaining.
Let's use variables to solve the problem. Let's say the initial number of pies before the sale started is "x."
After Mary set aside 4 pies, the number of remaining pies is (x - 4).
Karen bought half of the remaining pies, so the number of remaining pies becomes (x - 4)/2.
5 more pies were sold, reducing the number of remaining pies to (x - 4)/2 - 5.
According to the given information, (x - 4)/2 - 5 equals 19.
Now, we can solve the equation to find the value of x:
(x - 4)/2 - 5 = 19
Simplifying the equation, we have:
(x - 4)/2 = 24
(x - 4) = 48
x = 52
Therefore, there were 52 pies before the bake sale started.

how many times that a one-to-one function crosses the horizontal line?
We want to see how many times a one-to-one function crosses the x-axis (this is equivalent to see how many values of x are mapped into y = 0).
We will see that it crosses the x-axis only one time.
A function is a relation that maps elements from one set, the domain, into elements from another set, the range. Such that each element in the domain can be mapped into only one element in the range.
Now we add the restriction that the function is one-to-one, this means that no two elements from the domain can be mapped into the same element from the range.
With this is easy to see that the one-to-one function crosses the horizontal line only once, as the value y = 0 can be assigned to only one value in the domain.
