Olga flips 2 fair coins. What is the probability of obtaining a different result on each coin?
Answer:
2/4
Step-by-step explanation:
Probability of obtaining a different result on each coin is [tex]\frac{1}{2}[/tex].
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given
Olga flips 2 fair coins.
Probability of obtaining a different result on each coin
Total Number of favorable outcomes = {HH,TT,TH,HT} = 4
Number of favorable outcomes = {HT,TH} = 2
P(E) = [tex]\frac{Total Number of favorable outcomes }{Number of favorable outcomes}[/tex]
P(E) = [tex]\frac{2}{4}[/tex]
P(E) = [tex]\frac{1}{2}[/tex]
Thus, Probability of obtaining a different result on each coin is [tex]\frac{1}{2}[/tex].

f(x)=4x+1 and g(x)=x^2-5find(f-g)(x)
Answer:
-x²+4x +6Step-by-step explanation:
Given f(x)=4x+1 and g(x)=x²-5
(f-g)(x) is derived by taking the difference of both functions
(f-g)(x) = f(x)-g(x)
(f-g)(x) = 4x+1 - (x²-5)
(f-g)(x) = 4x+1-x²+5
(f-g)(x) = -x²+4x +6
This gives the requires expression

A 26-foot ladder is placed against a house and reaches the 24-foot roof. What is the distance between the base of the ladder and the base of the house if the ground meets the house at a right angle?
Answer:
The distance from the base of the ladder to the base of the house is 10ft
Step-by-step explanation:
From the question, we can gather that the ladder makes a right angle shape with the wall of the house.
The length of this ladder which represents the hypotenuse of the right angled triangle is 26ft while the height of the house to the roof is 24ft
To calculate the distance between the base of the ladder and the base of the house, we shall be employing the use of Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the square of the 2 other sides
We have established that the hypotenuse is the length of the ladder which is 26ft
Let the distance we want to calculate be d
26^2 = 24^2 + d^2
d^2 = 26^2 -24^2
d^2 = 676 - 576
d^2 = 100
d = square root of 100
d = 10ft
Answer:
10
Step-by-step explanation:
24^2 = 576
26^2 = 676
676 - 576 = 100
the square root of 100 is 10 so the answer is 10
Which is a correct first step in solving the inequality -4(2x - 1)> 5-3x?
Distribute -4 to get-8x + 4 >5-3x.
Distribute - 4 to get-Bx-1 > 5-3x.
Subtract 2x from both sides of the inequality.
Add 1 to both sides of the inequality.
Answer:-4(2x - 1) > 5 - 3x
solution:
-4(2x) -4(-1) > 5 - 3x Distribute -4 to get -8x + 4 > 5 - 3x
-8x + 4 > 5 - 3x
+3x + 3x

-5x > 1
÷ -5 ÷ -5
x < - 1/5
Answer:
A
Step-by-step explanation:
-4(2x - 1) > 5 - 3x
The first step would be to expand the brackets.
-4( 2x ) - 4( -1 ) > 5 - 3x
Distribute the -4 to 2x and -1 to get:

Steven and Jennifer meet their friends at the movies and buys them popcorn and drinks. Steven spends $138.50 for 12 drinks and 5 bags of popcorn. Jennifer buys two drinks and seven bags of popcorn for a total of $57. How much was each drink and each bag of popcorn?
Answer:
The cost of each drink was $9.25 and the cost of each popcorn was $5.5
Step-by-step explanation:
Let the cost of each drink be d
Let the cost of each popcorn be p
Steven spends $138.50 for 12 drinks and 5 bags of popcorn. This implies that:
12d + 5p = 138.50 _________ (1)
Jennifer buys two drinks and seven bags of popcorn for a total of $57. This implies that:
2d + 7p = 57 ______________(2)
We have two simultaneous equations/
12d + 5p = 138.50 _________ (1)
2d + 7p = 57 ______________(2)
Multiply (2) by 6 and subtract (1) from it:
12d + 42p = 342
- 12d + 5p = 138.50
———————————
37p = 203.5
p = $5.5
Puutting the value of p back in (2):
2d + 7(5.5) = 57
2d + 38.5 = 57
2d = 57 - 38.5 = 18.5
d = 18.5 / 2 = $9.25
The cost of each drink was $9.25 and the cost of each popcorn was $5.5

A circle can be characterized by its center's location and its radius's length. The point that lies on the circle is represented by the equation (x−3)² + (y+4)² = 6² is (-3,-4).
What is an equation of a circle?A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x-h)² + (y-k)² = r²
If a circle is graphed with the equation on the graph, also, all the points given are graphed, then it can be observed that the only point that lies on the circle is (-3,-4).
Hence, the point that lies on the circle is represented by the equation (x−3)² + (y+4)² = 6² is (-3,-4).

Answer:
lol don't listen to him/her, they're wrong.
it's 0.92, for plato. i got it right
Step-by-step explanation:
The probability that an athlete uses steroids, given that he tests positive is 0.92. Therefore, option E is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Let the total number of athletes be 'x'. and let 'P' denotes the probability.
Let A shows the event that a athlete test positive for steroids.
Let B shows the event that athlete use steroids as given in the question 12% of the athletes test positive for steroids=0.12 x.
P(A)=0.12 x
also we know that 11% of the athletes test positive for steroids actually use steroids=0.11 x.
P(A∩B)=0.11 x
Now we are asked to find the probability that an athlete uses steroids, given that he test positive that is we have to find
Now, P(B|A)=P(A∩B)/P(A)
= 0.11x/0.12x
= 0.92
Therefore, option E is the correct answer.
