the table below shows the linear relationship between the number of people at a picnic and the total cost of the picnic. which statements about the function described by the table are true? check all that apply. the independent variable is the number of people. the initial value (initial fee) for the picnic is $40. the rate of change is $8.67 per person. as the number of people increases, the total cost of the picnic increases. if 4 people attended the picnic, the total cost would be $46.
The correct statements are:
a) The independent variable is the number of people.
b) The initial value (initial fee) for the picnic is $40.
d) As the number of people increases, the total cost of the picnic increases.
A general linear equation is given by:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know that the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is given by the formula:
m = (y - y')/x - x'
Now let's analyze the table:
The x-values are the ones in the left and the y-values are the ones on the right, now from the table we can use two points, let's use the first two:
(6, 52) and (9, 58).
Then the slope is:
a = (58 - 52)/9 -6 = 2
Then the line is something like:
y = 2*x + b
To find the value of b, we use the point (6, 52). This means that when x = 6, y must be equal to 52.
We will get:
52 = 2*6 + b
52 = 12 + b
52 - 12 = b = 40
Then the linear equation is:
y = 2*x + 40
Now let's see which statements are correct.
a) The independent variable is the number of people.
True, the "x" represents the number of people.
b) The initial value (initial fee) for the picnic is $40.
True, the y-intercept does not depend on the value of x, so we can say that you need to pay that indifferent of the number of people that goes.
c)The rate of change is $8.67 per person.
False, the rate of change is equal to the slope, in this case is $2 per person.
d) As the number of people increases, the total cost of the picnic increases.
True.
e) If 4 people attended the picnic, the total cost would be $46.
To see if this is true or not, we just need to evaluate the function that we got in x = 4.
y = 2*4 + 40 = 48
So we can see that this is false.
Therefore, the correct statements are A, B, D

14) The sum of the digits of a two digit number is 12. The number obtained by reversing the digits is 18 less than the original number. What is the original number? Solve by using a system of equations. Write the 2 equations in the space provided. Show all work, including the method of your choice, used to solve.
Equation 1:
Equation 2:
The original number is 57.
The two equations are x+y = 12 and (10y+x)−(10x+y) = 18.
Let the digit at the tens place be x and the digit at the unit place be y.
x+y = 12 .........(1)
Required Number = (10x+y).
Number obtained on reversing the digits = (10y+x).
According to the condition, we get
(10y+x)−(10x+y) = 18
→ 9y−9x = 18
→ y−x = 2 ..........(2)
Adding (1) and (2), we get
2y = 14
y =7
x = 12 - 7
x = 5
Hence, the required number is 57.
The equations used to solve this is x+y = 12 and (10y+x)−(10x+y) = 18.

A card is drawn randomly from a standard 52-card deck. Find the following: Write all answers as simplified fractions (not mixed numbers). Probability the card drawn is a face card _____
Probability the card drawn is not a face card. ____
Odds in favor of drawing a face card ______
Odds against drawing a face card _____
The probability the card drawn is a face card is 3/13. The probability the card drawn is not a face card is 10/13. The odds in favor of drawing a face card is 3/10. The odds against drawing a face card are 10/3.
There are 52 cards in a standard deck, and 12 of them are face cards (jack, queen, and king). Therefore, the probability of drawing a face card is 12/52, or 3/13.
The probability of not drawing a face card is 1 minus the probability of drawing a face card. Since the probability of drawing a face card is 3/13, the probability of not drawing a face card is 1 - 3/13, which is 10/13.
The odds in favor of drawing a face card are 3:10, or 3/10. The odds against drawing a face card are 10:3, or 10/3.
In summary:
The probability the card drawn is a face card: 3/13
The probability the card drawn is not a face card: 10/13
Odds in favor of drawing a face card: 3/10

Answer: Im sorry I cant help im just doing this for points
Step-by-step explanation:
The correct answer is [tex]H_0: p = 0.24 and H_1: p < 0.24[/tex].
How to write this in maths notationIn mathematical notation, the null hypothesis can be written as:
H_0: p = 0.24
where p is the proportion of uninsured motorists in Florida.
The alternative hypothesis can be written as:
H_1: p < 0.24
This means that we are testing the hypothesis that the proportion of uninsured motorists has decreased to a level that is less than 24%.
The null hypothesis is the default assumption, and we will only reject it if we have enough evidence to support the alternative hypothesis. In this case, we would need to collect data that suggests that the proportion of uninsured motorists has decreased to a level that is significantly less than 24%.
The correct answer is [tex]H_0: p = 0.24 and H_1: p < 0.24[/tex].
The other options are incorrect because they either do not specify the direction of the hypothesis test (i.e., whether we are testing whether the proportion of uninsured motorists has increased or decreased) or they are not supported by the given information.

The volume of the cone is approximately 134 ft cube.
The cone would fit in 4 times in the red beach ball.
How to find the volume of a sphere and cone?The diameter of the red beach ball is 8 inches, then the cone has the same radius and a height of 8 inches .
Therefore, to know the number of times the beach ball will fit into the cone, we have to find the volume of each solid shape.
Therefore,
volume of the beach ball(sphere) = 4πr³
where
r = radiusr = 8 /2 = 4 inches
volume of the beach ball(sphere) = 4 × π × 4³
volume of the beach ball(sphere) = 256π ft³
Therefore,
volume of the cone = 1 / 3 πr²h
where
r = radiush = heightvolume of the cone = 1 / 3 × π × 4² × 8
volume of the cone = 128π / 3
volume of the cone = 42.7π
volume of the cone = 134.078
volume of the cone ≈ 134 ft³
Therefore,
volume of beach ball / volume of cone = 256π / 42.7π = 5.99531615925

He pays $500 each time. If the interest on the loan is 2% compounded semi-annually and he still has 8 years left to pay off the debt, how much does he still owe?
To find out how much Mark still owes on his debt, we need to calculate the amount of interest that has accrued on the loan over the time that he has been paying it off. The interest on the loan is compounded semi-annually, so the amount of interest that accrues on the loan will be added to the principal every six months. Since Mark has been paying off his debt for 8 years and the interest is compounded semi-annually, he will have made 16 payments of $500.
To calculate the total amount of interest that has accrued on the loan, we need to know the original principal amount of the loan. Since we don't have that information, we won't be able to calculate the exact amount that Mark still owes on his debt. However, we can use the information that we have to make an educated guess.
If Mark has been making payments of $500 every six months for eight years, then he has paid a total of $500 x 16 = $<<50016=8000>>8000 in principal and interest payments. If the interest on the loan is 2% compounded semi-annually, then the total amount of interest that has accrued on the loan over the past eight years is $8000 x 2% = $<<80002*.01=160>>160. This means that the original principal amount of the loan was $8000 - $160 = $<<8000-160=7840>>7840.
Since Mark still has 8 years left to pay off the debt, and he is making payments of $500 every six months, he will need to make a total of 8 years x 2 payments per year = <<82=16>>16 more payments of $500 to pay off the debt. This means that he will have to pay a total of $500 x 16 = $<<50016=8000>>8000 in principal and interest over the next eight years.
Since the total amount of interest that has accrued on the loan over the past eight years was $160, the total amount of interest that will accrue on the loan over the next eight years is also $160. This means that the total amount of interest that Mark will have to pay over the next eight years is $160 x 2 = $<<160*2=320>>320.
Adding the amount of interest that Mark will have to pay over the next eight years to the amount of principal that he will have to pay, we find that the total amount that Mark will owe on the loan over the next eight years is $8000 + $320 = $<<8000+320=8320>>8320.
Therefore, if Mark has been paying off his debt for eight years and still has eight years left to pay, he still owes a total of $8320 on the loan.

sum from k equals 0 to 4 of negative 12 plus 7 times k
sum from k equals 1 to 5 of negative 12 minus 7 times k
The option that represents the arithmetic series is;
Option C: sum from k equals 0 to 4 of negative 12 plus 7 times k
What is the formula for the arithmetic sequence?
An arithmetic series is defined as an arithmetic sequence, whereby each term of the series is gotten from the previous term by the addition or subtraction of a common term.
The series is given as;
-12 + (-5) + 2 + 9 + 16
By careful observation, we see that each term in the series is gotten from the previous term by the addition of 7.
The series here is therefore an example of arithmetic sequence.
The equation of the series when the first term is -12 can therefore be written as; -12 + 7·k
Where;
-12 is the first term
7 is the common difference
n is the number of terms
k = n - 1
When k = 0, we have;
-12 + 7·k
= -12 + 7 × 0
= -12
When k = 1, we have;
-12 + 7·k
= -12 + 7 × 1
= -5
When k = 2, we have;
-12 + 7·k
= -12 + 7 × 2
= 2
When k = 3, we have;
-12 + 7·k
= -12 + 7 × 3
= 9
When k = 4, we have;
-12 + 7·k
= -12 + 7 × 4
= 16
Therefore, we conclude that using values of k that range from k = 0 to k = 4, the expression that represents the series is therefore the option C

Answer:
To solve the given system of equations, we can start by substituting the value of x in the second equation into the first equation. Since the second equation tells us that x = y - 2, we can substitute y - 2 for x in the first equation to get:
x = 17 - 4y
y - 2 = 17 - 4y
Then, we can combine like terms on the right-hand side to get:
x = 17 - 4y
-3y = 15
Finally, we can divide both sides by -3 to solve for y, and then substitute this value back into one of the original equations to solve for x:
x = 17 - 4y
y = -5
x = 17 - 4(-5) = 17 + 20 = 37
Therefore, the solution to the system of equations is x = 37 and y = -5.

The missing features of the Venn diagram include the following:
I=472, II=449 ,IV=459 ,V=218 , VI=456,
What is a Venn diagram?A Venn diagram is a circular illustration of how variables are interrelated to each other.
To solve for I;
Total number of students taking dance = 1031
Total number of students taking science and dance= 449
Total number of students taking all three courses= 218
Total number of students taking science and English = 459
Therefore, the number of students taking only science;
I =( II-V)+ (IV-V)
I= (449-218)+(459-218)
I = 231+241
I= 472
The number of students that took Science, Dance, or English =V= 218
The number of students took Dance and English, but not Science = VI = 456
The number of students took Science or didn't take Dance = IV = 459
The number of students took none of the courses = VIII = U
The number of students took Science or English, but not Dance = 459 students.

write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros -2, 3, 8
A polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros -2, 3, 8 is x³ - 7x² + 36.
Define polynomial function.In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1.
Given,
As stated, the polynomial's leading coefficient is equal to 1.
The function's zeroes are also listed as -2, 3, and 6.
For root 3: ( x - 3)
for root 6: (x - 6)
As a result, the polynomial function is
f = 1(x+2)(x-3)(x-6) (x-6)
f = (x+2)(x² - 6x - 3x + 18)
f = (x+2)(x² - 9x + 18)
f = x³ - 9x² + 18x + 2x² - 18x + 36
f = x³ - 7x² + 36
A polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros -2, 3, 8 is x³ - 7x² + 36.

A spinner is divided into five equal sections labeled 1, 2, 3, 4, and 5. Another spinner
is divided into two equal sections labeled A and B. Nigel will spin each spinner one
time.
How many of the possible outcomes have a number less than 3 or an A?
Hint: first write out the sample space (you should have 10)
Which samples have a number less than 3 or an A?
Answer:
There are 5 possible outcomes when the first spinner is spun, and 2 possible outcomes when the second spinner is spun. Therefore, the sample space of possible outcomes when both spinners are spun is 5 x 2 = <<5*2=10>>10.
The possible outcomes are:
1A
1B
2A
2B
3A
3B
4A
4B
5A
5B
Of these, 3A, 2A, 1A, and 4B have a number less than 3 or an A. Therefore, there are 4 possible outcomes that have a number less than 3 or an A.
