Identify a pattern and find the next three numbers in the pattern.
6,12,18,24, . . .
The answer is 6, 12, 18, 24, 30, 36, 42.
The pattern is in increasing order i.e., +6.
How to find the pattern in the numbers?Given,
6,12,18,24, . . .
Solution:
Note the difference in the given number series 6,12,18,24, . . .
12 - 6 = 6
18 - 12 = 6
24 - 18 = 6
The difference is common and is 6.
The sequence is in increasing order.
So, add 6 to 24 and the consecutive numbers to get the answer.
24 +6 = 30
30 +6 = 36

An equation of he line through the points (-2,5) and (3,-4)
The equation of the line passing through points (-2,5) and (3,-4) is 9x + 5y = 7.
Hence, option C) 9x + 5y = 7 is the correct answer.
What is the equation of line that passes through the points (-2,5) and (3,-4)?Given the data in the question;
Point1 (-2,5)
x₁ = -2y₁ = 5Point2 (3,-4)
x₂ = 3y₂ = -4First, we determine the slope of the of the line,
m = (y₂-y₁)/(x₂-x₁)
m = ( -4-5 )/( 3-(-2) )
m = -9/5
Using the formula for equation, we determine the y-intercept
y = mx + b
Plug in the first point (-2,5) and the slope and then solve for the y-intercept b.
5 = -9/5(-2) + b
5 = 18/5 + b
b = 5 - 18/5
b = ( 25 - 18 )/5
b = 7/5
Now, plug the slope and y-intercept into y = mx + b to determine the equation of the line.
y = mx + b
y = -(9/5)x + 7/5
Convert to standard form
y = -(9/5)x + 7/5
Multiply each term by 5
5y = -9x + 7
5y + 9x = 7
9x + 5y = 7
The equation of the line passing through points (-2,5) and (3,-4) is 9x + 5y = 7.
Hence, option C) 9x + 5y = 7 is the correct answer.

What is surface area of cuboid ?
The six rectangular faces of a cuboid. Add the areas of each of the cuboid's six faces to determine its surface area. Additionally, we can label the prism's length (l), width (w), and height (h), and then calculate its surface area using the formula SA=2lw+2lh+2hw.Let y = total charge for a car rental and x = miles driven
Proxy car equation: y = 0.32x + 18
YourPal equation: y = 0.36x + 12
Set equations right sides equal to each other... meaning their cost, y, are equal
0.32x + 18 = 0.36x + 12
18 = 0.04x + 12 (subtract 0.32x from both sides of the equation)
6 = 0.04x (subtract 12 from both sides of the equation)
150 = x (divide both sides of the equation by 0.04)

Suppose that e and f are two events and that p(e)=0.6 and p(f|e)=0.4. what is p(e and f)?
The required value of p(e and f) is 0.24, which is calculated using the conditional probability formula.
What is conditional probability?
Conditional probability is the measure in probability theory that depicts the probability of occurrence of an event given that another event has already occurred. Its mathematical formulation is given by:
P(A/B) = P(A∩B) / P(B)
Here, A is the event and B has already occurred
The calculation for the value of p(e and f)
The assigned value of p(e) = 0.6
Conditional probability, p(f/e) is given as 0.4
We know, that conditional probability = p(e∩f) / p(e)
W need to calculate p(e∩f) which is equal to p(f/e) × p(e)
p(e∩f) = 0.4 × 0.6
= 0.24
Hence, the value of p(e and f) is 0.24.

The Atlanta Falcons scored 13 more points than twice the number of points that the Miami Dolphins scored. Altogether, the teams scored 43 points. How many points did the Dolphins score? Is 21 a viable solution to this problem?
Yes, because 21 points is less than the total number of points scored
No, because 2(21) + 13 ≠ 43
Yes, because 21 points is less than the number of points Atlanta scored
No, because 2(21) ≠ 43
Answer:
No, because 2(21) + 13 is not equal to 43.
The Dolphins scored 10 points.
Step-by-step explanation:
A = 13 + 2D
43 = 13 + A + D
43 = 13 + 3D
43 - 13 = 30
30 = 3D
30/3 = 10
D = 10
A = 13 + 2(10)
A = 33
D + A = 43
33 + 10 = 43
Therefore, the Atlanta Falcons scored 33 points which is 13 points more than twice what the Dolphins scored.

The equation of the line satisfies the given conditions. the line passes through (25,24) and is perpendicular to y=6 is x = 25.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Solve each inequality. Check your solution. 3n < -4(2+n)
The inequality given by 3n < -4(2 + n) has the solution n < -8/7 or (-∞ , -8/7).
Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.
To solve an inequality is to find the values of x such that when we substitute that number for x we have a true statement.
Given the inequality 3n < -4(2 + n), expand the right term by distributing -4 inside the parenthesis.
3n < -4(2 + n)
3n < -8 - 4n
Add 4n to both sides.
3n + 4n < -8 - 4n + 4n
7n < -8
Divide both sides by 7
7n < -8
n < -8/7
To check, let n = -9/7
n = -9/7 < -8/7
Substitute this value to the inequality.
