If a car can travel 300 miles in 4 hours, how far can it go in an hour and a half?
Answer:
112.5miles
Step-by-step explanation:
4hrs=8 half hours
And 1hr30min=3 half hours
If a car travels 300miles in 8 half hours with the mathematical expression of
300miles-8hh
Then for the 3 half hour we have
X-3hh
Comparing the two
300miles-8hh
Xmiles-3hh
By cross multiplying
8×X=3×300
8X=900
X=900/8
X=112.5miles

Determine whether each sequence is arithmetic. If so, identify the common difference. 1,1,2,3,5,8, ...........
The sequence 1,1,2,3,5,8, ........... doesn't form an AP as they have the varying common difference.
What is the sequence of AP arithmetic progression?In Arithmetic Progression, the difference between these two numerical orders is a fixed number (AP). Arithmetic Sequence is another name for it.
We'd come across a few specific keywords in AP that had been labeled as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)As shown below, the AP can also be explained in expressed in the form of common differences.
The following is the procedure for evaluating an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' : d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, the sequence given is; 1,1,2,3,5,8, ...........
The series contains of given 6 terms.
Let the initial term be 'a₁' = 1.
The second term be 'a₂' = 1.
The third term be 'a₃' = 2.
And, the fourth term is 'a₄' = 3.
For the sequence to form the AP, they must have the equal common difference. So,
d = a₃ - a₂
Substitute the values.
d₁ = 2 - 1
d₁ = 1
Thus, the calculated common difference is 1.
or d = a₅ - a₄ (Put the values)
d₂ = 5 - 3
d₂ = 2
Since, d₁ ≠ d₂
Thus, we can say that the given sequence is not forming an AP.

How to get the equation of a line
Answering the Question
There are a couple ways we can get the equation of a line, depending on what we're given.
The Equation FormMost linear equations are organized in slope-intercept form:
[tex]y=mx+b[/tex]
m = slopeb = y-interceptSlopeThe slope of a line can be calculated algebraically when we know two points that fall on the line:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the two pointsY-interceptThe y-intercept is the value of y when the line crosses the y-axis, or when x = 0. When given a graph, you can sometimes read the y-intercept directly from the graph.
For instance, if the line passes through the point (0,5), then the y-intercept is 5.
You can also find the y-intercept algebraically if you know the slope and one point that falls on the line. You plug in that point as (x,y) and isolate b.
Summary
For most cases, you can use the following method to find the equation of a line:
Find the slope of the line (using the slope equation) and plug it into y=mx+bFind the y-intercept of the line algebraically and plug it into y=mx+bSelect the correct answer.
The spread of data set X is greater than the spread of data set Y, and the data sets are normally distributed. Which statement is true?
OA The mean of data set XIs greater than the mean of data set Y.
OB. The median of data set X is less than the median of data set Y.
OC. The standard deviation of data set Xis greater than the standard deviation of data set Y.
OD. The range of data set X is less than the range of data set Y.
O E.
The mode of data set X is greater than the mode of data set Y.
Answer:
C
Step-by-step explanation:
Just the spread of normally distributed data tells us nothing about the mean, mode or median, so answers A, B, and E are out of question.
The range is based on the difference between the highest and lowest elements. As there can be big outliers, we have no idea if D is true, although we expect distributions with bigger spread to generally exhibit bigger ranges.
We're left with answer C. Standard deviation is a measure of "how much the data can deviate from the mean". It's also one of the measures of spread. We expect data that's more spread out (higher spread) to have a higher standard deviation.

Write each equation in slope-intercept form. Then find the slope and y -intercept of each line. - [ (1/2)x - y ] = 3/4
The slope is 1/2 and the y-intercept is 3/4 in the equation - [ (1/2)x - y ] = 3/4.
What is a slope of line?A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.
The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.
Therefore,
m = y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.
Be aware that tan ∅ = y/x
We also refer to this tan as the line's slope
We know that the equation for slope(m) and y - intercept(c) of a line is given by :
y = mx + c
Here given the equation - [ (1/2)x - y ] = 3/4, lets simplify
⇒ - [ (1/2)x - y ] = 3/4
⇒ -(1/2)x + y = 3/4
⇒ y = (1/2)x + 3/4
Hence, the slope is 1/2 and the y-intercept is 3/4 in the equation - [ (1/2)x - y ] = 3/4

From the Soldier's point of view, the American Civil War was not a continuous battle. Instead, it was long monotonous marches and long residency in camps punctuated by the terror and chaos of combat. When winter set in and the campaigning season came to a close, most Soldiers counted on a long, cold stay in a winter camp. The four log cabins at the center of the Army Heritage Trail represent the types of buildings which Soldiers in both the Union and the Confederate Armies spent the long dreary months of winter. The cabins are modeled after images from the USAHEC collection, including the Army of the Potomac's winter camp at Brandy Station and the Confederate camp at Centerville

Write an explicit and a recursive formula for each arithmetic sequence. -2,-13,-24, . . . . .
Given an arithmetic sequence -2,-13,-24, . . . , the recursive formula is: a(n) = a(n-1) -11 and the explicit formula is a(n) = 9 - 11n
Suppose we are given an arithmetic sequence:
a(1), a(2), a(3), a(4), ....
Then, in an arithmetic sequence, the next term is obtained by adding a constant to the previous term. This constant is called a common difference.
Let d = common difference, then
a(2) = a(1) + d
a(3) = a(2) + d
and so on, until
a(n) = a(n-1) + d
This is a recursive formula. Here a(n) = nth term, and a(n-1) = (n-1)th term.
The sequence in the problem:
-2,-13,-24, . .
Notice that:
-13 = -2 + (-11)
-24 = -13 + ( -11)
Hence, d = -11, and therefore, the recursive formula for the nth term is:
a(n) = a(n-1) -11
To find the nth term, we can also use the explicit formula:
a(n) = a(1) + (n-1).d
In the given sequence, a(1) = -2, and d = -11. Substitute these parameters:
a(n) = -2 + (n-1) . (-11)
= -2 - 11n + 11
= 9 - 11n
Thus, the explicit formula is a(n) = 9 - 11n.
