The King's records for January, February, March, April and May show that their expendiures totaled $3,012, $2,977, $2,340, $3,333 and $2,765, respectively. What is their average monthly expenditure for the five months?
Answer:
Average cost= $2,885.4
Step-by-step explanation:
Giving the following information:
February, March, April and May show that their expendiures totaled $3,012, $2,977, $2,340, $3,333 and $2,765, respectively.
First, we need to calculate the total expenditures:
Total cost= 3,012 + 2,977 + 2,340 + 3,333 + 2,765
Total cost= $14,427
Now the average cost:
Average cost= total cost / number of moths
Average cost= 14,427 / 5
Average cost= $2,885.4
Perform the indicated operation.

The value of a boat is $22,000. It loses 20% of its value every year. Find the approximate monthly percent decrease in value. Round your answer to the nearest hundredth of a percent. PLZ HELP! I"LL GIVE BRAINLIEST!!!!
Answer:
If it lost 20% of the original value per year, it lost $4,400 in value in the first year.
There are 12 months in a year.
4,400 divided by 12 is 366.67 (rounded since this is about money)
So the boat lost $366.67 in value each month for the first year.
Or 1.67% value per month

H e l p p l e a s e i n e e d h e l p i m d u m b
Answer:
1/2
Step-by-step explanation:
To compare 3/8 with the answer choices, you need to make sure they have a common denominator. You can achieve this by multiplying each answer choice with 4/4 to get a common denominator of 8. Now, your answer choices are: 0, 4/8, 8/8, and 12/8. From these, 4/8 is the closest to 3/8, which means that rounding 3/8 to the nearest half will get you 4/8, which is equal to 1/2. Thus, your answer is 1/2.

please help solve for x ................................................................
Answer:
104°+33°+(5x+13)°=180°[all angle sum is 180°]
137°+(5x+13)=180°
137°+13+5x=180°
150°+5x=180°
5x=180°-150°
5x=30
x=30/5
×=6
Answer:
x = 6
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
5x + 13 + 104 + 33 = 180, that is
5x + 150 = 180 ( subtract 150 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6

What is the best definition for "sample" as used in statistics? the entire population of the group a part of the population that represents the entire population the difference between the maximum and minimum values observed a measure of how much the values within a population vary
Answer:
a part of the population that represents the entire population
Step-by-step explanation:
A sample simply refers to a smaller group of observation usually drawn from a larger group or a collection of the total possible observation that fits a particular or specific characteristic(population). This smaller group or subset of observation is usually chosen to be representative of the larger group of population. Representative Samples are usually obtained by drawing at random from the population and are very important where using the entire population for a study seems impossible or very expensive or intensive.

Point O is a centroid of the triangle LMN. If OM=38 cm, what is MP?
a.) 114 cm
b.) 19 cm
c.) 57 cm
d.) 25.5 cm
9514 1404 393
Answer:
c.) 57 cm
Step-by-step explanation:
The centroid divides the median into parts with a 2:1 ratio.
OM : OP = 2 : 1
OM : MP = 2 : (2+1) = 2 : 3
As a fraction with MP on top, this is ...
MP/OM = 3/2
MP = (3/2)OM = 3/2×(38 cm)
MP = 57 cm
__
Comment on the answer choices
Often, you can eliminate a number of the choices in a multiple-choice question just by testing whether they are reasonable. Here, the longer part of a line segment has length 38, so the whole segment will not be shorter than that. The choices 19 and 25.5 make no sense.
The remaining choices are 114 cm and 57 cm. The former is 3 times the length of the given segment, which the drawing tells us is unreasonable.
The only reasonable choice offered is 57 cm.

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,047
was collected on the sale of 1,291 tickets. How many of each type of ticket were sold?
The basketball game sold
adult tickets and
student tickets.
Answer:
The basketball game sold 439 adult tickets and 858 student tickets.
Step-by-step explanation:
A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is, in the systems of equations, one must look for the values of the unknowns, with which when replacing, they must give the solution proposed in both equations.
Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,047 was collected on the sale of 1,291 tickets.
With "x" the number of adult tickets sold and "y" the number of student tickets sold, you have the following system of equations:
[tex]\left \{ {{x+y=1291} \atop {5*x+1*y=3047}} \right.[/tex]
Through the substitution method, you must solve for one of the unknowns in one of the equations and substitute its value in the following one: in this case you solve for the variable y from the first equation:
y=1291 -x
and you replace in the second equation:
5*x + 1291 - x= 3047
Solving, you get:
5*x-x= 3047 - 1291
4*x= 1756
x= 1756÷4
x=439
Replacing this value in the expresion y=1291 -x you get:
y=1291 -439
y= 858
The basketball game sold 439 adult tickets and 858 student tickets.
y is inversely proportional to the cube root of x
When y = 2500, x = 64
(a) Find the value of y when x = 8
(b) Find the value of x when y = 2000
Answer:
b) Find the value of x when y = 2000
find. the value of y when x 8
