The graph shows the height, y, in centimeters, of a plant after a certain number of weeks, x. Shania drew the line of best fit o

tia_tia [17]

You are given a a graph titled Plant Height that shows Number of Weeks on x axis and Height of Plant in cm on y axis. Plotting this and you will get an equation of y = 1.2792x - 0.1665 (I used excel using the given points from the above problem).

y = 1.2792x - 0.1665
y = 1.2792 (7) - 0.1665
y = 8.78 centimeters.

The most likely approximate height of the plant after 7 weeks is 8.7 centimeters.

Randall recorded 8 songs on his most recent CD the total length of the CD is 49 minutes find a until rate to represent the avera

olganol [36]

Answer:

6.125 minutes per song

Step-by-step explanation:

Unit rates are based on a single unit of something. Like price per 1 gallon of gas; price for 1 pound of bananas; miles driven per 1 gallon of gas, etc. What we are looking for in minutes per song.

Use a proportion to solve this with minutes on top and number of songs on the bottom. We know that 49 minutes = 8 songs, and we want to know how many minutes (x) per 1 song:

$\frac{min}{song}:\frac{49}{8}= \frac{x}{1}$

Cross multiply to get

8x = 49 so

x = 6.125 minutes per song

Aroon is asked to choose five integers so that the mode is 2 more than the median and the mean is 2 less than the median.

torisob [31]

The mean is the sum of observations divided by number of observations.

x bar = (∑x)/n
The median is the middle value of the ordered data or the value of the interval n+1/2 for odd numbered data.
The mode is the repeated value.

<h3>The highest value is 0</h3>

Number of observations= n= 5
Median is the 3rd value when the data is arranged.
Mode is unknown

The relation between Mean, Median and mode is given by

Mode= 3 Median - 2Mean---- equation1

According to the given condition

Mode= 2+median ----- equation 2

Putting equation 2 in equation 1

2+median= 3 Median - 2Mean

2 Mean= 3 Median - 2- Median

2 Mean= 2 Median - 2

Mean= Median-1

Mean- Median=1--------Eq. A

According to the second condition

Median- Mode=-2-----------eq. 3

Putting eq. A in eq. 3

Mean -1 - Mode=-2

Mean- Mode=-1

Mode- Mean=1------equation 4

Adding equation A and equation4

Mode- Mean=1

Mean- Median=1

Mode+ Median =2------- equation5

Again Putting equation2 in equation 5

2+median + Median =2

2 Median =2-2

2 Median =0

Median=0

Mean= 0-1

Mean= 0-1=-1

Mode- Mean=1

Mode-(-1)=1

Mode=0

Putting values in the formula of mean

x bar =∑x/5

(-1)5 = 0+0+ x1+x2+0

-5= x1+x2

So the highest value is 0.
