T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released. The average rate of change in T(d) for the interval d = 4 and d = 10 is 0. Which statement must be true?
A: Fewer tickets were sold on the fourth day than on the tenth day.
B:No tickets were sold on the fourth day and tenth day.
C: The same number of tickets was sold on the fourth day and tenth day.
D: More tickets were sold on the fourth day than on the tenth day.
The statement that must be true since the average rate of change T(d) for the interval d = 4 and d = 10 is 0 is this:
C: The same number of tickets was sold on the fourth day and tenth day.
What is the average rate of change?The average rate of change is a measurement that shows how much the function of a unit changes over a given interval. In the above question, we can see that the average rate of change given the two intervals is zero and this means that there was no change among the variables.

What is parabola?A parabola is an approximately U-shaped, mirror-symmetrical planar curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves.
One definition of a parabola includes a line and a point (the focus) (the directrix). The directrix is not the main focus. The locus of points in that plane that are equally spaced apart from the directrix and the focus is known as the parabola.
Given a horizontal parabola centered on the origin opens to the left,
the equation for a horizontal parabola,
(y − b)² = 4p(x − a), p≠0
a and b are the vertex of parabola,
since the parabola is centered on the origin, a and b are (0, 0)
vertex of parabola is at (0, 0),

Mia pend 1/4 of her money on a ticket, he ha 30 pound left. How much wa the ticket ?
Mia spend 1/4 of her money on a ticket, he has 30 pound left. Therefore the ticket was 120 pound.
Pound:
The sterling is the currency of the United Kingdom and nine associated territories. The pound (symbol: £) is the primary unit of sterling, and the word "pound" is also commonly used to refer to British currency, and in international contexts is often British It is called pound or pound sterling.
The sterling is the world's oldest currency still in use and has been in continuous use since its creation. It is currently the fourth most traded currency in the foreign exchange market, after the US dollar, the euro and the Japanese yen. Together, these three currencies and the renminbi form a basket of currencies for calculating the value of the IMF's Special Drawing Rights. As of late 2022, the pound is the world's reserve currency and he is also the fourth most held reserve currency.
According to the question:
Since, 1/4 of her money is spent on the tickets.
Then , there left 3/4 part of money.
Therefore,
So she spent a total of 1/4 of her money in the tickets, and therefore had 3/4 of her money left at the end. So 3/4 of the money she started with is 30 pound.
Therefore she started with 30 * 4 = 120 pound.

Find an expression to present the perimeter of the rectangle below
An expression to represent the perimeter of the rectangle with 10/(x² + 11x +24) and (x+1)/(x+3) would be (x+12)(x+6)//(x+8)/(x+3).
What is the perimeter?
A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter. There are numerous uses in real life for perimeter calculations.
Here, we have
Given: Sides = 10/(x² + 11x +24) and (x+1)/(x+3)
The perimeter is when you add all the sides of a shape.
In a rectangle, two sides are the same, and so are the other two. therefore, if the two sides are 10/(x² + 11x +24) and (x+1)/(x+3) the expression will be:
= 2(10/(x² + 11x +24)) + 2(x+1)/(x+3)
= 20/(x² + 11x +24) + 2(x+1)/(x+3)
= 20/(x+8)/(x+3) + 2(x+1)/(x+3)
= {20 + 2(x+1)(x+8)}/(x+8)/(x+3)
= {20 + 2(x² + 9x + 8)}/(x+8)/(x+3)
= { 20 + 2x² + 18x + 16}/(x+8)/(x+3)
= {2x² + 18x + 36}/(x+8)/(x+3)
= (x+12)(x+6)//(x+8)/(x+3)
Hence, an expression to represent the perimeter of the rectangle with 10/(x² + 11x +24) and (x+1)/(x+3) would be (x+12)(x+6)//(x+8)/(x+3).

1. |5+m|<13 is an "or" compound inequality. 2. 4|y + 6| ≥ 3 is neither compound inequality. 3. null set.
1. The inequality is given in the question, is as follows:
|5+m| < 13
The absolute value of the expression "5+m" is less than 13.
To solve the inequality, we need to split the inequality in two separate inequalities: 5+m < 13 and -5-m < 13.
Thus, |5+m|<13 is an "or" compound inequality.
2. 4|y + 6| ≥ 3 is neither compound inequality because we have just one inequality.

How do you know if a number is integer or decimal?In this method, we will check the number by dividing it with 1, if it is completely divided by 1 then the function will return value as 0 and the number is a whole number. Otherwise, the number is a decimal point number.Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.An integer, also called a "round number" or “whole number,” is any positive or negative number that does not include decimal parts or fractions.

The value of k are the graphs (equations) equal is k = -3/2

How to find for what value of k are the graphs equal?Since we have the two equations 12y = -3x + 8 and 6y = kx -5, re-writing them, we have
12y = -3x + 8

Comparing with (1) and (2), with (3) and (4) above, we have that
a = 3, b = 12c = -8a' = -kb' = 6 andc' = 5So, using a/a' = b/b', we find k.
So, substituting the values of the variables into the equation, we have that
a/a' = b/b'
⇒ 3/-k = 12/6
Cross-multiplying, we have that
3 × 6 = -k × 12
k = -3 × 6/12
k = -3/2
So, the value of k = -3/2

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 447 gram setting. Based on a 24 bag sample where the mean is 444 grams and the standard deviation is 10, is there sufficient evidence at the 0.1 level that the bags are underfilled or overfilled? Assume the population distribution is approximately normal.
Step 5 of 5: Make the decision to reject or fail to reject the null hypothesis.
The decision rule for is to reject null if critical value is higher than the test statistic, since there is insufficient evidence to show that the machines are underfilling the bag.
How to carry out the hypothesis testFirst we have to solve for the test statistic
t = x - u / s /√n
the variables are stated as:
where x = 444
u = 447
n = 24
s = 10
we would have the test statistic solved as :
444 - 447 / 10 / √24
-3 / 2.0412
= -1.4697
at 0.1 significance level, we would have:
degree of freedom
n - 1
= 24 - 1 = 23
the critical value is -1.3194.
Because the critical value is greater than the test statistic, we are going to reject the null.

Can someone explain this, I got x = 0
Elena and Jada each make money by helping out their neighbor. Elena babyit. Her earning are given by the equation y=8. 40x, where x repreent how many hour he work and y repreent how much money he earn. Jada earn $7 per hour mowing her neighbor' lawn. How long would it take to make each peron 150$?
If Elena earn y = 8.40x dollars where x represent how many hours she work and Jada earn $7 per hour, it would take Elena approximately 17.86 hours and Jada approximately 21.43 hours to earn $150
To find out how many hours it would take for Elena to earn $150, we need to solve the equation:
y = 8.4x
150 = 8.4x
x = 150/8.4
x ≈ 17.86 hours
So it would take Elena approximately 17.86 hours to earn $150.
To find out how many hours it would take for Jada to earn $150, we divide 150 by her hourly rate:
= $150 /( $7/ hour)
≈ 21.43
So it would take Jada approximately 21.43 hours to earn $150.
