Answer:
5 months and the cost is $430
Step-by-step explanation:
Let's start by figuring out the equations for both dance studios.
Q : 30 registration fee plus 80 per month.
R : 105 registration fee plus 65 per month.
We can use the variable m for months.
Registration is a flat fee, so that will be it's own term. Plus the costs per month. We will multiply the costs per month times months, m.
Q : 30 + 80m
R : 105 + 65m
Now, if we want to find out how many lessons until the costs are equal, we need to make the two equations equal to each other.
80m + 30 = 65m + 105
Now, we work backwards to find out what m is.
Subtract 30 on both sides.
80m = 65m + 75
Subtract 65m on both sides
15m = 75
Divide by 15 on both sides to isolate m.
m = 5
After 5 months, the total cost of the dance lessons will be equal at the two studios. To find out the cost, we must multiply the months back in. We can substitute 5 in for any of the equations as they are equal. I will use 80m + 30.
80(5) + 30 = ?
400 + 30 = ?
430 = ?
The cost for both studios will be equal at 5 months, with a cost of $430.

From the given frequency table, we observe that the chicken lays 5 or more eggs on day 4, 5 and 6, and the eggs laid by the chicken are the greatest on day 4.
What is a frequency table?A frequency distribution table is a tool for structuring the provided data in a way that makes sense and facilitates comprehension. Two or three columns make up a frequency distribution table.

All of the results are shown in the first column as individual values or as class intervals.
The table's second column contains the results' totals, which also display the frequency as vertical lines. It's not required.
The frequency of each result is revealed in the third column.
The frequency table uses lines to depict the number of laid eggs. Here, 5 is represented using a hashed line over four lines. Thus, we see that the maximum number of eggs laid are 6, on day 4.
Also, the chicken lays 5 or more eggs on day 4, 5 and 6.

In a raffle, 1,500 tickets are sold for $3 each. One ticket will be randomly selected and the winner will receive a laptop computer valued at $1000. What is the expected value for a person that buys one ticket?
e(x)=-2.33
how do you find that answer ?
The solution to probability problem is the expected value for a person that buys one ticket is -$2.32
What is probability?Probability is a measure of the likelihood or chance that a specific event will occur, expressed as a number between 0 and 1, where 0 represents impossibility and 1 represents certainty.
According to the given information:
To find the expected value, you need to multiply each possible outcome by its probability and then add them together.
In this case, there are two possible outcomes: either the person wins the laptop computer (with a probability 1/1500), or they don't win anything (with a probability 1499/1500).
So, the expected value can be calculated as:
E(x) = (1/1500)($1000) + (1499/1500)(-$3)
E(x) = $0.67 - $2.99
E(x) = -$2.32
So the expected value for a person that buys one ticket is -$2.32.

If a polynomial f\mathopen{}\mathclose{\left(x\right)}f(x) has a remainder of 22 when divided by x-6x−6, what is f\mathopen{}\mathclose{\left(6\right)}f(6)?\
f\mathopen{}\mathclose{\left(6\right)}f(6) = (6-6)(something) + 22 = 0(something) + 22 = 22 which has a remainder of 22 when divided by x-6x-6. f\mathopen{}\mathclose{\left(6\right)}f(6) = \boxed{22}.
What is the remainder theorem?The remainder theorem states that when a polynomial is divided by a linear term, the remainder equals the value of the polynomial at the root of the linear term. This theorem may be used to determine the roots of a polynomial by dividing it by a linear term and solving for the remainder. For instance, when the polynomial x3+x2-5x+6 is divided by (x2), the result is identical to the polynomial's value at x=2. After finding the remainder, we may determine that the polynomial's root is 2, which we can do by solving for the remainder. This theorem may also be used to discover the roots of higher degree polynomials by combining linear terms.
How to solve?
f\mathopen{}\mathclose{\left(x\right)}f(x) can be written as (x-6)(something) + 22.
f\mathopen{}\mathclose{\left(6\right)}f(6) = (6-6)(something) + 22 = 0(something) + 22 = 22.
Therefore, f\mathopen{}\mathclose{\left(6\right)}f(6) = \boxed{22}.

10 Find the value of 2x+y for the simultaneous equations.
3x + 5y = 48
2x-y=19
y=3
x=11
hence answer 25
3x+5y=48
2x-y=19
eliminate x to find y
(3x+5y=48)2
(2x-y=19)3
(6x + 10y. = 96)
- minus direct
(6x - 3y. = 57)
=
13y = 39
Note: (10y -(-3y)=13y)
divide by 13 to remain with y
y =3
substitute to any equation to get x lets pick second one
2x-(3)=19
2x-3=19
2x=19+3
2x/2=22/2. (to remain with x value)
x=11
therefore 2x+ y results to 2(11) +3=25
Answer:
2x + y = 25
Step-by-step explanation:
Given equations:
[tex]\begin{cases} 3x + 5y = 48\\\;\;2x-y=19\end{cases}[/tex]
Rearrange the second equation to isolate y:
[tex]\implies 2x-y=19[/tex]
[tex]\implies 2x-19=y[/tex]
Substitute the found expression for y into the first equation and solve for x:
[tex]\implies 3x+5y=48[/tex]
[tex]\implies 3x+5(2x-19)=48[/tex]
[tex]\implies 3x+10x-95=48[/tex]
[tex]\implies 13x=143[/tex]
[tex]\implies x=11[/tex]
Substitute the found value of x into the equation for y and solve for y:
[tex]\implies y=2x-19[/tex]
[tex]\implies y=2(11)-19[/tex]
[tex]\implies y=22-19[/tex]
[tex]\implies y=3[/tex]
Therefore, the solution of the given system of equations is:
x = 11, y = 3To find the value of 2x + y, substitute the found values of x and y into the expression and solve:
[tex]\begin{aligned}\implies 2x+y&=2(11)+3\\&=22+3\\&=25\end{aligned}[/tex]

represents the height of the plant above ground level, and x represents the
number of days since it was planted.
a. What is the y-intercept of the best fit line? What does the y-intercept of the line mean in this situation? Is it reasonable?
The y-intercept of the line of best fit is -5.18cm and it is showing the initial height of the plant immediately it was planted and it is not reasonable because it shows a negative height
The general form of the equation of a line in slope intercept form is expressed as;
y = mx + c
where;
m is slope
c is y-intercept.
Now, we are given the equation of the line of best fit as;
y = 0.404x - 5.18
where;
y represents the height of the plant above ground level.
x represents the number of days since it was planted.
a) From the given equation, we see that the slope is; m = 0.404 and that the y intercept is -5.18.
Now, what the y-intercept means is that the height of the plant is 5.18 cm below the ground and this is not reasonable.

Given the table below, write a linear equation that defines the
dependent variable, a, in terms of the independent variable, p.
Someone help
Answer:
a = 4p + 3
Step-by-step explanation:
The general form of a linear equation is y = mx + b
where y is the dependent variable, x the independent variable
m = slope(rate of change)
b = y-intercept which is the value of y when x = 0
In this problem, instead of x we are asked to use p and instead of y we are using a
Therefore we get
a = mp + b
We have to compute m and b
Since b is the value of a when p = 0, we can easily see that a = 3 when p = 0
Therefore:
a = mp + 3
To determine m, take any value of p, find the corresponding a from the table, plug in these values and solve for m
When p = 1, a= 7
So we get
7 = m(1) + 3
7 = m + 3
or
m = 7-3 = 4
So the equation is
a = 4p + 3
You can verify this as correct by plugging in different values for p from the table and checking if you get the corresponding a value
