Answer:
x = (-39)/11
Step-by-step explanation:
Solve for x:
x - 9 = (3 (5 x + 1))/4
Multiply both sides by 4:
4 (x - 9) = (4×3 (5 x + 1))/4
(4×3 (5 x + 1))/4 = 4/4×3 (5 x + 1) = 3 (5 x + 1):
4 (x - 9) = (3 (5 x + 1))
Expand out terms of the left hand side:
(4 x - 36) = 3 (5 x + 1)
Expand out terms of the right hand side:
4 x - 36 = (15 x + 3)
Subtract 15 x from both sides:
(4 x - 15 x) - 36 = (15 x - 15 x) + 3
4 x - 15 x = -11 x:
-11 x - 36 = (15 x - 15 x) + 3
15 x - 15 x = 0:
-11 x - 36 = 3
Add 36 to both sides:
(36 - 36) - 11 x = 36 + 3
36 - 36 = 0:
-11 x = 3 + 36
3 + 36 = 39:
-11 x = 39
Divide both sides of -11 x = 39 by -11:
(-11 x)/(-11) = 39/(-11)
(-11)/(-11) = 1:
x = 39/(-11)
Multiply numerator and denominator of 39/(-11) by -1:
Answer: x = (-39)/11

researchers collect continuous data with values ranging from 0-100. in the analysis phase of their research they decide to categorize the values in different ways. given the way the researchers are examining the data - determine if the data would be considered nominal, ordinal or ratio (you may use choices more than once).
The data in the given three questions can be considered as nominal, ordinal and ratio, respectively.
The frequency (or absolute frequency) of an event in statistics is the number of times the observation occurred or was recorded in an experiment or research.Within a variable, nominal data is data that may be labelled or categorized into mutually exclusive groups. These categories cannot be meaningfully arranged.Ordinal data is a sort of categorical, statistical data in which the variables have natural, ordered categories but the distances between them are unknown.Two categories ( low vs high): frequency of values between 0-49 and frequency of values between 50-100 : nominal Three frequency (count) categories (low, medium, and high) of values ranging from 0 to 25, 26 to 74, and 75 to 100 : ordinalAnalyze each number in the set individually : ratioTo learn more about frequency, visit :

3:00 pm, 12:30 pm, 10:00 pm,…. conjecture: next term:
The next arrival in the sequence 3:00 pm, 12:30 pm, 10:00 pm,... is 7:30 A.M.
The given sequence is 3:00 pm, 12:30 pm, 10:00 pm,...
Let us first find the difference between the arrivals from the given sequence
3:00 pm - 12:30 pm = 2:30
12:30 pm - 10:00 pm = 2:30
Since, each arrival time is 2 hours and 30 minutes prior to the previous arrival time.
Therefore, the next arrival is:
10:00 pm - 2:30 = 7:30 am
Thus, the next arrival in the sequence is 7:30 A.M.

write the ratio 9:4 in the form n:1
The ratio in the form of n:1 is 2.25:1.
what is ratio?When comparing two amounts of the same sort, ratio is utilised. For two numbers, a and b, the ratio formula is written as a: b or a/b. Two or more ratios are said to be in proportion if they are all equal.
A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same sort and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
ratio 9:4
Now we have to write the ratio in the form of n:1
So, divide the ratio by 4
=9 /4 : 4/4
=9/4: 1
=2.25 :1
Hence, the ratio in the form of n:1 is 2.25:1.

Answer:

Step-by-step explanation:
Find an equation for the line below.
To find the equation of a line, you need to use the formula [tex]m=\frac{y-y_0}{x-x_0}=\frac{rise}{run}[/tex] to find the slope first.
To find the respective points that we need to plug into this formula, we need to use the axes and their values.
We can see that the first point (point on the left) has a position of (-1, -1). For the second point, we see that it has a position of (5, 1).
** remember, whenever you find the position of a point, it's always (x, y). Now that we have our values, we can plug and chug!
[tex]m=\frac{y-y_0}{x-x_0}\\m= \frac{1-(-1)}{5-(-1)} \\m=\frac{1+1}{5+1} \\m=\frac{2}{6} \\m=\frac{1}{3}[/tex]
So your answer should be 1/3 for your slope.
Now you need to find your y intercept, or what y will equal if x = 0. We can find this by using the information we now have. Remember, the equation for a linear line is [tex]y=mx+b[/tex]. So now, we plug in any of the two points (it doesn't matter which pair!) and solve for b!
[tex]y=mx+b\\-1=\frac{1}{3}(-1)+b\\ -1=-\frac{1}{3}+b\\-1+\frac{1}{3}=b\\b=-\frac{2}{3}[/tex]
Now we have b!
So now, we can fully finish the equation of this line. Your final answer should be: y = (1/3)x - 2/3 or [tex]y=\frac{1}{3}x-\frac{2}{3}[/tex].
