Find an expression for the number in the nth term pattern of the sequence.
4 , 7 , 12, 19
Answer:
n^2 + 3.
Step-by-step explanation:
4 7 12 19
Differences are 3 5 7 so this a quadratic sequence.
2nd difference = 2 2
So the first part of the expression is n^2
Terms: 4 7 12 19
n^2 1 4 9 16
Difference = 3 3 3 3 3
So the answer is n^2 + 3.
0.5757… as a fraction
Answer:
Your answer is [tex]\frac{19}{33}[/tex]
Step-by-step explanation:
That is kind of hard. I have used the internet to help create that repeating decimal to a fraction and got that as your answer.
Answer:
19/33
Step-by-step explanation:
There are two repeating decimals so divide 57 (repeating part)... by 100x minus x
57/100x -x
57/100x - x = 0
100x - x = 57
99x=57
x=57/99

What is the slope of the line that passes through the points (4, 7) and (8, 9)
Answer:
y = 0.5x + 5
Step-by-step explanation:
Use the slope formula to find the slope of a line given the coordinates of two points on the line.
The slope formula is:
m = [tex]\frac{y{2}-y{1} }{x{2}- x{1} }[/tex] = [tex]\frac{y}{x}[/tex]
The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
Now let's fill in the formula with the points,
m = [tex]\frac{8-4}{9-7}[/tex]
Solve,
⇒ Y = 9 – 7 = 2
⇒ X = 8 – 4 = 4
m = [tex]\frac{8-4}{9-7}[/tex] = [tex]\frac{2}{4}[/tex]
Simplify,
⇒ [tex]\frac{2}{4}=\frac{1}{2}=0.5[/tex]
Therefore, the Equation of the line is y = 0.5x + 5.

Is the data set approximately periodic? If so, what are its period and amplitude?
Considering the given table and the periodicity concept, it is found that the data set is not periodic.
What is the period of a data-set?The period of a function is given by the distance between it's repetitions.
An example of a periodic data-set with a period of 3 would be 1,2,3,1,2,3,1,2,3,...
In this problem, looking at the table, it is found that there are no patterns of repetitions, that is, the number of cars washed do not follow a repeated pattern, hence the data set is not periodic.

Ryan used 50 apples to make several pies. He put the same number of apples in each pie. He had 1 apple left over. How many pies did he make ?
Answer:
7
Step-by-step explanation:
50-1 = 49
Since all pies must have the same amount of apples, we can do √49 and get 7, meaning there are 7 pies with 7 apples each.
Answer: 7
Step-by-step explanation: of he had 1 apple left, he used 49 Apples.
if he used sane number of apple in each pie, we can use square root of 49 which is 7

The exam scores for 200 students are normally distributed with a mean of 72 and a standard deviation of 10. Which answer choice below represents the number of students with scores between 72 and 82?.
Using the normal distribution, it is found that there are 68 students with scores between 72 and 82.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by:
[tex]\mu = 72, \sigma = 10[/tex]
The proportion of students with scores between 72 and 82 is the p-value of Z when X = 82 subtracted by the p-value of Z when X = 72.
X = 82:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{82 - 72}{10}[/tex]
Z = 1
Z = 1 has a p-value of 0.84.
X = 72:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{72 - 72}{10}[/tex]
Z = 0
Z = 0 has a p-value of 0.5.
0.84 - 0.5 = 0.34.
Out of 200 students, the number is given by:
0.34 x 200 = 68 students with scores between 72 and 82.

the same. Working together, how many minutes
will it take them to unload 35 truckloads of
hay?
Answer:
600 minutes ( 10 hours)
Step-by-step explanation:
rate c = 1 job/30 min
rate r = 1 job/40 mi

please show work.
In this article, I will show you how to find the area of a circle and express your answer in terms of pi (π). First, you'll need to familiarize yourself with the formula for calculating the area of a circle:
A = π * r²
Let's define our variables:
A: area of the circle
π: pi (a mathematical constant that is approximately equal to 3.141492 . . .)
r: radius of the circle (the distance from the circle's center point to its edge)
Typically, to find the area of a circle, we would simply plug in the circle's radius for r and 3.141592 for π. If so, our answer would be a number.
Therefore, the answer is 16π.

Under his cell phone plan, Oliver pays a flat cost of $49 per month and $5 per gigabyte. He wants to keep his bill at $73.50 per month. How many gigabytes of data can he use while staying within his budget?
He must consume only 4.9 gigabytes to maintain his bill at $73.50 per month.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
According to the question,
Oliver pays a flat cost of $49 per month and $5 per gigabyte.
Let the number of gigabytes he consumes be x,
He wants to keep his bill at $73.50 per month. So,
49 + 5x = 73.50
5x = 73.50 - 49
x = 24.5/5
x = 4.9
He must not consume less or more than 4.9 gigabytes to maintain his bill at $73.50 per month.
Thus, he must consume only 4.9 gigabytes to maintain his bill at $73.50 per month.
