Answer:
1/4
Step-by-step explanation:
HT represent the probability of tossing a head then Tail.
There is 4 possible results and only 1 give us HT.
We call this theoretical probability. which is
[tex] \frac{x}{y} [/tex]
where x is favorable outcomes and y is total number of outcomes.
So there is a 1/4 probability of getting a head followed by a tail.
1) A head followed by a head.
2) A head followed by a tail.
3) A tail followed by a head.
4) A tail followed by a tail.
Therefore,
Total possible outcomes = 4
Now, the given condition is a head followed by a tail. In the possible outcomes there is only one (i.e; 2) that satisfies this condition.
Therefore, outcome of getting head followed by tail = 1
Finally,
P(getting head followed by tail) = outcome of getting head followed by tail / Total possible outcome.
Which is 1/4.
Hope this helps.

Answers
Answer:
45 degrees
Step-by-step explanation:
Hi there!
We're given that one of the triangle's exterior angles is 90 degrees. Using that, we can solve for the corresponding interior angle by subtracting 90 from 180 degrees:
180-90 = 90
Given that the two legs of this right triangle are of equal length, we know that the remaining two angles both measure x. Knowing that the sum of the interior angles in a triangle is 180 degrees, we can set up an equation:
x+x+90=180
2x=90
x=45
Therefore, x is 45 degrees.
In fact, any right triangle with legs of equal length will be a 45-45-90 triangle, meaning the other two angles measure 45 degrees.

Given m || n, find the value of x and y.
Answers
Answer:
x = 60
y = 60
Step-by-step explanation:
To find y (y and 120 are supplementary angles):
y + 120 = 180
y = 180 - 120
y = 60
x = y (because of corresponding angles)
x = 60
If angle 1 and angle 2 are vertical angles, and the m<1 = 10x - 9 and m<2 = 4x + 15. Find the value for x.
Answers
Answer:
x = 4
Step-by-step explanation:
Vertical angles are equal.
m∠1 = m∠2
10x - 9 = 4x + 15
Add 9 to both sides
10x = 4x + 15 + 9
10x = 4x + 24
Subtract 4x from both sides
10x -4x = 24
6x = 24
Divide both sides by 6
x = 24/6
x = 4

Step-by-step explanation:
Sum of angles = 180, so

8x = 180 - 140 = 40
x = 40/8 = 5
Jonathan has no money and he owes three friends fifteen dollars each. What is his worth?
Answers
Answer:
-$45
Step-by-step explanation:
Find how much he owes his friends in total by multiplying 3 by 15:
3(15)
= 45
So, he owes his friends $45.
Since he has no money, we can find his worth by subtracting 45 from 0:
0 - 45
= -45
His worth is -$45.
When Ms. Perez has excellent service at a restaurant, the amount she leaves for a tip t is at least 20% of the cost of the meal c. Write a model representing the amount of the tip.
Answers
Answer:
t ≥ 0.2c
Step-by-step explanation:
Her tip is at least 20% of the cost of the meal, so her tip is greater than or equal to 20% of the cost of the meal
tip ≥ 20% of the cost of the meal
t ≥ 20% of c
Another way of writing "20% of c" is multiplying the two values, so we have
20% of c = 20% * c
t ≥ 20% * c
To convert from a percentage to a decimal, we can divide the percentage by 100. Here, we have
20% = 0.2
t ≥ 0.2 * c

The new graph is the inverse of the time vs height graph, but I’d not a function. How would you restrict the domain on the original function to make it invertible?
Answers
Using inverse function concepts, it is found that the domains that make the function invertible are: [tex]t \in [0, 2.5][/tex] of [tex]t \in [2.5, 5][/tex].
-----------------------------------
A function is invertible if each output is related to only one value of the input.-----------------------------------
In the graph given in this question, other than the maximum height at [tex]t = 2.5[/tex] seconds, all outputs are related to two input values.To be invertible, the domain has to be divided at the half-way point, either between 0 and 2.5 seconds, or between 2.5 seconds and 5 seconds. This way, each output will be related to only one input.Thus, the domains that make the function invertible are: [tex]t \in [0, 2.5][/tex] of [tex]t \in [2.5, 5][/tex].

At the beginning of March, a store bought a leather couch at a cost of $960.70 and marked it up 20%. At the end of the month, the leather couch had not sold, so the store marked it down 25%. What was the discounted price? Submit
Answers
Answer: $864.63
Step-by-step explanation:
First find the original price. Write 20% as the decimal 0.20 before using it in the equation.
price
= cost+mark-up
= 960.70+0.20×960.70
= 960.70+192.14
= 1,152.84
The original price was $1,152.84.
Now find the discount price. Write 25% as the decimal 0.25 before using it in the equation.
discount price
= original price–discount
= 1,152.84–0.25×1,152.84
= 1,152.84–288.21
= 864.63
The discount price was $864.63.
