Find the first differences for each data set, and write an equation to represent the data pattern
The first differences for each data set is 120 120 120 120 120 120, and the equation to represent the data pattern is y = 120
How to find the first differences for each data set, and write an equation to represent the data pattern?The table of values represents the given parameters
On the table of values, we have the following function range
60 180 300 420 540 660 780
Calculate the first differences for each data set
i.e. Difference = Tn - T(n-1) Where n > 1
So, we have
120 120 120 120 120 120
The numbers in the above pattern are the same
So, the equation can be represented as
y = 120
Hence, the first differences for each data set is 120 120 120 120 120 120, and the equation to represent the data pattern is y = 120

42 miles kelly's car can go if 1 gallon of gas is used .
WHAT IS UNITARY METHOD ?Using the unitary approach, you can solve problems by first figuring out the value of a single unit, then multiplying that value by the number of units you need.
CALCULATIONtotal miles travelled = 26 1/4 miles = 26.25 miles
gas used = 5/8 = 0.625 gallon
distance car can travel in 1 gallon = 26.25 / 0.625

What is the Pythagorean theorem?According to the Pythagorean Theorem, the hypotenuse square in a right-angled triangle equals the square of the sum of the other two sides.
This statement states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
This is a right-angled triangle which means that the missing length can be solved using the Pythagorean theorem:
c² = a² + b²
Where c is the hypotenuse, a and b are the other sides.
c = 6
a = 3
b =?
6² = 3² + b²
36 = 9 + b²
b² = 27

How to simplify arational algebraic expressions
Answer:
To simplify any rational expressions, we apply the following steps:
Factorize both the denominator and numerator of the rational expression. Remember to write each expression in standard form.
Reduce the expression by cancelling out common factors in the numerator and denominator
Rewrite the remaining factors in the numerator and denominator.
Step-by-step explanation:
Example:
Simplify: (x^{2} + 5x + 4) (x + 5)/(x^{2} – 1)
Solution:
Factoring the numerator and denominator to get;
⟹ (x + 1) (x + 4) (x + 5)/(x + 1) (x – 1)
Now cancel the common terms.
⟹ (x + 4) (x + 5)/(x – 1)

m∠UVX = 76 and m∠XVW = 64, what is the measure of m∠UVW
Based on the angles addition postulate, m∠UVW = 140°.
What is the Angles Addition Postulate?The angles addition postulate says that two smaller angles that is composite of a larger angle can be added together to give the measure of the larger angle.
Based on the angle addition postulate, the following equation that can be used to solve the problem given is derived below:
measure of angle XVW + measure of angle UVX = measure of angle UVW
Given the following:
measure of angle UVX = 76°
measure of angle XVW = 64°
Thus, using the above equation, we have:
64 + 76 = measure of angle UVW
140 = measure of angle UVW
measure of angle UVW = 140°

Why is the GCF of two prime numbers always one
Answer:
Step-by-step explanation:
A prime number has only two factors (1 and itself). Hence, two prime numbers cannot have any common factor other than 1. Therefore, the greatest common factor of two prime numbers is always 1. For example, the greatest common factor of 5 and 7 is 1.
Determine the probability of following event, rolling a pair of dice and not getting a 3
According to the question, the probability of the event in which rolling a pair of dice and not getting a 3 is as follows:
What is Probability?
The term probability means the study of the occurrence or the outcomes of the event. It is the measurement of the events that occurred during events. And many uncertain events cannot be measured.
Probability of not getting 3= 1 - P(getting three)/Total number of events
Probability of not getting 3=1-2/36 = 1-1.18 =17/18
Hence, the probability of not getting three while rolling a pair of dice is 17/18 .

What is meant by centroid theorem?The triangle's centroid is the point where the three medians intersect. According to the centroid theorem, the centroid is 23 times the distance from each vertex to the midpoint of the opposite side.
The centroid has the unique property that the distance from a vertex to the centroid is twice that of the distance from the centroid to the midpoint of the side opposite that vertex for each median. In addition, the three medians of a triangle divide the triangle into six equal-area regions.
Given: In Δ SZU, UJ = 9, VI = 3 , and ZT = 18 .
Since ZV ≅ VU, Y is the midpoint of UZ and SV is a median of Δ ZSU. Similarly, points Y and T are also midpoints of SZ and SU, respectively, so YU and ZT are also medians. Therefore, point J is the centroid of
Δ ZSU and, according to the Centroid Theorem, SJ is 2/3 of SV.
SJ = 2/3 (SV)
= 2/3 (SJ + VJ)

there are three age groups in a competition.
john wants to do a survey of the competitors.
he uses a stratified sample of exactly 50 competitors according to each age group.
work out the number of competitors in each age group that should be in his stratified sample of 50
There are 10 people in the 16-18 group , 22 people in the 19-24 group and 18 people who are 25+ in the stratified sample.
A method of sampling from a population that can be divided into subpopulations is known as stratified sampling in statistics. When subpopulations within a larger population differ in statistical surveys, it may be desirable to sample each subpopulation separately.
From the given table we can calculate the total of population:
population = 120 + 250 + 200 = 570 people
Now since it is a stratified sample, the ratio of each age group is equal in the sample as in the population.
∴Number of people in the 16-18 group :
[tex]=\frac{120}{570} \times 50\\\\=10.52[/tex]
∴Number of people in the 19-24 group :
[tex]=\frac{250}{570} \times 50\\\\=21.929[/tex]
∴Number of people in the 19-24 group :
[tex]=\frac{200}{570} \times 50\\\\=17.543[/tex]
Now as 10.52 is closer to 10 than 17.54 is closer to 17 , we will round off 10.52 to 10.
Hence there are 10 people in the 16-18 group , 22 people in the 19-24 group and 18 people who are 25+ in the stratified sample.

The mass of the planet Mercury is 1.74 × 10⁻⁴ kg time the mass of the planet Jupiter.
Mass of Mercury = 3.3 × 10²³ kg
Mass of Jupiter = 1.9 × 10²⁷ kg
We need to find that how many times the mass of Mercury is the mass
