Question:
You flip a fair coin ; What is P(heads)? If necessary, round your answer to 2 decimal places
Answer:
[tex]P(Head) =0.50[/tex]
Step-by-step explanation:
Given:
A fair coin
Required
Determine [tex]P(Head)[/tex]
A coin has two faces (Head (1) and Tail (1) )
i.e. 1 head and 1 tail
Both of which have equal probability, which is calculated as follows:
[tex]P(Head) = P(Tail) = \frac{1}{1 + 1}[/tex]
[tex]P(Head) = P(Tail) = \frac{1}{2}[/tex]
[tex]P(Head) = P(Tail) = 0.5[/tex]
Hence:
[tex]P(Head) =0.50[/tex]
Answer: Its 0.50

Answer:
y=-4x+1
Step-by-step explanation:
m=-4
h=1
Answer:
Step-by-step explanation:
b is the y intercept. Start with b. The graph shows that the point (0,b) is (0,1)
So far what you have is y = mx + 1
Now you have to deal with m
m = (y2 - y1)/(x2 - x1)
m = (1 - 0)/(0 - -1/2) = 1 /0.5 = 2 Use your calculator for this.
So the line is y = 2x + 1
As you move into the shaded area y > 2x + 1
I reproduced the graph to show that pointed the arrow in the right way. You can try it to see if it works by trying a couple of points. y should work out to be greater than 2x + 1
Five friends ate lunch together. They each paid the same amount the total cost of all five meals was $51.94 which included a 6% sales tax, what was the cost of one meal before tax was added?
Given:
Total number of friends = 5
Total cost of all five meals = $51.94
Sales tax = 6%
To find:
The cost of one meal before tax was added.
Solution:
Let x be the cost of all five meals before tax.
Then, Amount of tax = 6% of x
According to he question,
[tex]x+\dfrac{6}{100}x=51.94[/tex]
[tex]x+0.06x=51.94[/tex]
[tex]1.06x=51.94[/tex]
Divide both sides by 51.94.
[tex]x=\dfrac{51.94}{1.06}[/tex]
[tex]x=49[/tex]
So, the cost of all five meals before tax is $49.
Divide this cost by 5 to get the cost of one meal before tax was added.
[tex]\dfrac{49}{5}=9.8[/tex]
Therefore, the cost of one meal before tax was added, is $9.8.

Answer:
a.
Step-by-step explanation:
(2, 10) and (4, 10) have the same y value so it's not a function etc. etc.
Answer:
D. The relation represents y as a function of x, because each value of x is associated with a single value of y
Step-by-step explanation:
As long as no one x-value has two solutions, it can be considered a function. The x-values are {0, 2, 4, 6, 8}. Since there isn't any repetition, this can be considered as a function. The fact that 10 is repeated in the y-values doesn't affect that it is a function.

Answer:
$68.00
Step-by-step explanation:
Let s represent the opening price. Then the closing price is ...
s - 3.25% × s = $65.79
s(1 -0.0325) = $65.79 . . . . collect terms
0.9675s = $65.79 . . . . . . . simplify

Zeno jumped 8 meters. Then he jumped half as far again (4 meters). Then he jumped half as far again (2 meters). So after 3 jumps, he was 8 + 4 + 2 = 14 meters from his starting place.
a. Zeno kept jumping half as far again. How far would he be after 4 jumps?
14/2 = 7
7/2 = 3.5
3.5/2 = 1.75
1.75/2 = 0.875
9514 1404 393
Answer:
15 meters
Step-by-step explanation:
Zeno's last jump was 2 meters, so another jump half as far adds 1 meter to the 14 m total.
After 4 jumps, Zeno would have jumped 15 meters from his starting place.

Comment on the question
The given distances give a total "after 3 jumps." The question asks for a total "after 4 jumps." It is not clear whether that is 4 jumps total, or 4 more jumps. In the above, we have assumed it is 4 jumps total.

Answer:
Step-by-step explanation:
Since on each day 9 shells were found, and there are 7 days: 7 x 9 = 63
Number of shells found this summer: 63
Number of shells found fewer this year than last year: 152 - 63 = 89
Hence, Jon’s family found 63 fewer shells than last year
Jon’s family found 63 fewer shells than last year if last summer, Jon’s family found 152 shells at the beach. This summer they were at the beach for 7 days.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
Last summer, Jon’s family found 152 shells at the beach. This summer they were at the beach for 7 days.
Let x be the number of shells they find this year than last year.
The value of x can be found as follows:
x = 152 - 7×9
x = 152 - 63
x = 89 shells
Thus, Jon’s family found 63 fewer shells than last year if last summer, Jon’s family found 152 shells at the beach. This summer they were at the beach for 7 days.

krytine has a weekend job advertising an upcoming play. she has two options for being paid. Option A is an hourly wage of $7.50 Option B is 5% commission on all money made at the play. she plans to work 7 hours each day on Saturday and Sunday. krystine estimates the play will make about $2,000 this weekend. Which option gives more earnings this weekend?
The Answer is: The hourly rate option of $112 is higher than the commission rate of $105.
Step-by-step explanation:
She will work 16 hours at $7.00 per hour:
16 * 7 = $112
Or she could take the 5% commission on $2,100:
2100 * .05 = $105.
The hourly rate is higher than the anticipated commission amount.

What is the value of the expression 5y² + 4x when x = 2.5 and y = 3?
Answer:
55
Step-by-step explanation:
the value of the expression 5y² + 4x when x = 2.5 and y = 3 will be 55.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given an expression 5y² + 4x
To calculate the value of expression at x = 2.5 and y = 3
Substitute the value of x and y in the expression:
=> 5y² + 4x
=> 5* 9 + 4 * 2.5
=> 45 + 10
=> 55
therefore, 55 is the value of the expression 5y² + 4x when x = 2.5 and y = 3.
