Jennifer belongs to a gym that requires a monthly membership fee of $100 plus an additional $10 fee for each yoga class she atte

MrRissso [65]

First of all, we need to know what is the slope-intercept form which is:
y=mx+b where m represent slope and b represent y intercept
Then,
Let y represent the total amount of money that Jennifer pays monthly
mx represent the total amount of money that Jennifer pays for classes she attends
b represent the memberships fee, so:
y=10x+100 the following slope-intercept form equations models the total amount that Jennifer pays monthly. Hope it help!

PLEASE HELP!!! I don't understand.

Answer:

arithmetic: 130
geometric: ±50

Step-by-step explanation:

Arithmetic sequence

The terms of an arithmetic sequence have common difference. If the missing term is x, then the difference between terms is the same:

x -250 = 10 -x

2x = 260 . . . . . . add 250+x to both sides

x = 130 . . . . . . . . divide by 2

The missing term of an arithmetic sequence is 130.

(the common difference is -120)

Geometric sequence

The terms of a geometric sequence have a common ratio. If the missing term is x, then the ratios between terms are the same:

x/250 = 10/x

x^2 = 2500 . . . . . . . multiply both sides by 250x

x = ±√2500 = ±50 . . . take the square root

The missing term of a geometric sequence is +50 or -50.

(the common ratio is ±1/5)

3. Make a class frequency table using 2 rule of the following data. Find the Mean and make a Cumulative frequency Histogram [10]

sashaice [31]

Answer: Mean = 284

Step-by-step explanation:

Data:

125, 126, 127, 127, 137

201, 202, 207, 211, 215, 218, 224, 237, 261

301, 308, 310, 315, 330, 330, 360, 380, 393, 394

401, 401, 410, 421, 422, 424

Class Frequency Table:

$\boxed{\begin{array}{c|c|c}\underline{\text{Intervals}}&\underline{\text{\qquad Frequency\qquad}}&\underline{\text{Cumulative Frequency}}\\0-49&0&0\\50-99&0&0\\100-149&5&5\\150-199&0&5\\200-249&8&13\\250-299&1&14\\300-349&6&20\\350-399&4&24\\400-449&6&30\\450-499&0&30\end{array}}\\.\qquad \qquad \qquad \qquad \quad \ 30$

Mean:

The sum of the numbers divided by the quantity of numbers:

8518/30 = 283.933

Cumulative Frequency Histogram:

Create the graph based on the Interval and Cumulative Frequency of the class frequency table above. (see image)
