At a photography contest, entries are scored on a scale from 1 to 100. At a recent contest with 1,000 entries, a score of 68 was at the 77th percentile of the distribution of all the scores. Which of the following is the best description of the 77th percentile of the distribution?
a. There were 77% of the entries with a score less than 68.
b. There were 77% of the entries with a score greater than 68.
c. There were 77% of the entries with a score equal to 68.
d. There were 77 entries with a score less than 68.
There were 77% of the entries with a score less than 68. Therefore, the correct answer is option A.
Given that, at a recent contest with 1,000 entries, a score of 68 was at the 77th percentile of the distribution of all the scores.
A score X being in the xth percent of a distribution means that x% of the scores are below X and 100 – x% of the scores are above X.
In this question, we have that:
A score of 68 is in the 77th percentile of the distribution.
This means that 77% of the scores are below 68, and 100 – 77 = 23% of the scores are above 68.
Therefore, the correct answer is option A.

Suppose you have a population in which 60% of the people approve of gambling. Is the value 0.60 a parameter or a statistic
Answer:0.60 is a parameter .
Step-by-step explanation:
In statistics, a parameter is a number that summarize the data for a whole population.
On the other hand , statistic gives a measure for sample of population.
Given: We have a population in which 60% of the people approve of gambling.
60% = 0.60
Since it is a measure for the population , it is denoted as population parameter.
Hence, 0.60 is a parameter not statistic.
Write an equation of the locus of all points equidistant from the x axis and the y axis and whose coordinates have the opposite signs.
Answer:
y=-x
Step-by-step explanation:
Since the y-axis and x-axis are intersecting lines then you need to apply the locus of intersecting lines which would be the angle bisector and since the problem is asking for the opposite signs you need to make it -x instead of x.

As pointed out, you lose if the pile has 1, 6, 11 or 16 sticks. How many sticks are needed in the next two piles for you to lose
Answer:
21 and 26 totaling 47sticks
Step-by-step explanation:
Th number of sticks form an arithmetic progression
1, 6, 11, 16...
The nth term of an arithmetic progression is expressed as;
Tn = a+(n-1)d
a is the first term = 1
d is the common difference
d = 6-1 = 11-6 = 5
n is the number of terms
The next two terms are the fifth and sixth term
T5 = 1+(5-1)5
T5 = 1+4(5)
T5 = 1+20
T5 = 21
T6 = 1+(6-1)5
T6 = 1+5(5)
T6 = 1+25
T6 = 26
Hence the number of sticks needed in the next two piles are 21 and 26 totaling 47sticks

Mike was ordering pizzas for a party. He ordered triple the number of sausage pizzas as cheese pizzas. He ordered twice as many pepperoni pizzas as cheese. He also requested a fourth as many supreme pizzas as pepperoni. If he paid for 39 pizzas total, how many of each type of pizza did he order? Write an equation or draw a diagram to support your answer.
Answer: Number of cheese pizzas = 6
Number of sausage pizzas =18
Number of pepperoni pizzas = 12
Number of supreme pizzas = 3
Step-by-step explanation:
Let x= Number of cheese pizzas.
Number of sausage pizzas = 3x
Number of pepperoni pizzas = 2x
Number of supreme pizzas = [tex]\dfrac{2x}{4}=\dfrac{x}{2}[/tex]
Total pizzas = [tex]x+3x+2x+\dfrac{x}{2}=39[/tex]
[tex]\Rightarrow\ \dfrac{13x}{2}=39\\\\\Rightarrow\ x=\dfrac{39}{13}\times2\\\\\Rightarrow\ x=6[/tex]
Number of cheese pizzas = 6
Number of sausage pizzas = 3(6) = 18
Number of pepperoni pizzas = 2(6) = 12
Number of supreme pizzas = [tex]\dfrac{12}{4}=3[/tex]

If a number reads the same forwards or backwards, like 404 and 1221, then it's called a palindrome. The first palindrome greater than 9999 is 10 001. What is the fifth palindrome greater than 9999?
Answer:
The fifth Palindrome greater than 9999 is 10,401
Step-by-step explanation:
Here, we want to get the fifth palindrome greater than 9999
To get this, we are going to write out the palindromes that are greater than 9999
we have them as follows to the fifth
10,001
10,101
10,201
10,301
10,401
So the fifth Palindrome greater than 9999 is 10,401
Use the Distributive Property to expand 2 (-3x + 5).
Answer:
-6x+10
Step-by-step explanation:
The distributive property states that multiplying each term will yield the same product as multiplying the sum. This means to expand this expression multiply both addends by 2 then add together. So, the new expression is, 2 * -3x + 2 * 5, which simplifies to -6x+10.
Answer:
Step-by-step explanation:
-6x+10

What is the solution of the following systems of equations? y = 1/2x
y = -x -3
Answer:
x = -2, y = -1
Step-by-step explanation:
System of Equations
Solve the system:
y = 1/2x
y = -x - 3
Multiplying the first equation by 2:
2y = x
Substituting x in the second equation:
y = -2y - 3
Adding 2y:
3y = -3
y = -3/3
y = -1
And x = 2*(-1) = -2
Solution: x = -2, y = -1
A woman purchased a used car for $3,000. She decided to sell the car for 20% above her purchase price. She could not sell the car so she reduced asking price by 20%. If she sells the car at the reduced price, she will have a profit or a loss or will she break even?
10.1 #17
Answer:
She will have a loss of $ 120
Step-by-step explanation:
Purchase price of car = $ 3000
20% of 3000 = [tex]\frac{20}{100}*3000[/tex]
= 20 * 30
= $ 600
Selling price = 3000 + 600 = $ 3600
Reduction price = 20% of 3600
[tex]\frac{20}{100}*3600[/tex]
= 20 * 36
= $ 720
Current selling price after reduction = 3600 - 720
= $ 2880
Loss = 3000 - 2880
= $ 120

Two cuboids have the same surface area
one is (1 , a , 9) and the other is (2 , a , 7)
what is a?
Answer:
a = 5
Step-by-step explanation:
Surface Area of a Cuboid
Given a cuboid of dimensions x,y, and z, the surface area is:
A = 2xy + 2yz + 2xz
The first cuboid of dimensions 1,a,9 has a surface area of:
A1 = 2a + 18a + 18 = 20a + 18
The first cuboid of dimensions 2,a,7 has a surface area of:
A2 = 4a + 14a + 28 = 18a + 28
Both areas are equal, thus:
20a + 18 = 18a + 28
Rearranging:
20a - 18a = 28 - 18
2a = 10
a = 5

Step-by-step explanation:
Answer:
We are asked to find the area of the rectangle that has side lengths of 3/4 yard and 5/6 yard.
We know that area of rectangle is width times length.
To find the area of the given rectangle we will multiply both side length as:
Area of regatangle = width x Lenghth
Area of regtangle = 3/4 x 5/6 yard to the 2 power
Area of regtangle = 1/4 x 5/2 yard to the 2 power
Area of regtangle = 1 x 5/ 4x2 yard to the 2 power
Area of regtangle = 5/8 yard to the 2 power
Therefore, the area of the given rectangle would be 5/8 square yards.
In the figure below, k || o. Find the values of y and z.
Answer:
y = 112
z = 27
Step-by-step explanation:
Alright,
So we know that a straight line adds up to 180. And looking at the figure, it looks like 68 + y = 180 if you do some visualization.
So, we can already calculate y.
y = 180 - 68
y = 112
Now we find z. z here is represented in an expression. We can see that y and the expression z is in are congruent to each other which means they will equal each other. And since we know that y = 112, we know that the expression z is in is also equal to 112.
So we set up an equation like so:
112 = 3z + 31
And start to simplify:
81 = 3z
Finally we divide:
27 = z
Therefore, z is 27
