Answer:
A scatter plot is a plot or graph where you apply cartesian coordinates to display data.
You should have Plotted your graph already with "Birth weight" as the independent variable and Adult weight" as the dependent Variable.
Now
To answer the second part of the page.
It said
Which regression Equation would best model the data
Y=mx + c
You need to get this equation either using Micro soft excel(You can search for the steps online) or using the formula below
m= n(£xy) - (£x)(£y) / [ n(£x²) - (£x)²]
For C
C= £y - m(£x) / n
You'd need to draw a diagram and figure out these values
You need to be careful and know that £x² is not same as (£x)²
Know this to avoid mistakes.
Do this and fix your m and c values to get you regression line Equation.
Note: £ stands for Summation.
Evaluate those numbers like you would a statistical data.
Step-by-step explanation:
And For the Last... question...
We see a correlation... As the x value tends to increase.... y value also follows. This correlation is positive... So yeah... Its expected to grow exponentially

A simple impact crater on the moon has a diameter of 15 kilometers. A complex impact crater has
a radius of 30 kilometers. How much greater is the circumference of the complex impact crater than
the simple impact craters?
Answers
Answer:
141.3 km
Step-by-step explanation:
First crater has the radius (that is, half the diameter) of 7.5 km; the circumference of this crater is C = 2(pi)r, or 2(3.14)(7.5 km) = 47.1 km;
Second crater radius is C = 2(pi)(30 km) = 188.4 km
The circumference of the complex (larger) impact crater is
(188.4 - 47.1) km greater than the circumference of the simple (smaller) crater:
141.3 km

Sabi has $2.50 more than Toni. Together they have $17.50. How much does Toni have?
Answers
Answer:
6.25
Step-by-step explanation:
17.50/2=8.75
8.75+2.50=11.25
17.50-11.25=6.25
Answer:
Toni has $7.50
Step-by-step explanation:
Tobi = x
Sabi = x + 2.5
x + x + 2.5 = 17.5
2x + 2.5 = 17.5
2x = 15

Caitlyn recorded the height of each plant after she exposed each plant to a set amount of darkness daily. The scatterplot shows her results after 2 weeks of exposing each plant to the amount of darkness.
A graph titled Plant Growth has hours of darkness on the x-axis, and height of plant (inches) on the y-axis. Points are grouped closely together and decrease. Point (17, 12) is above the cluster.
Which statement about the scatterplot is true?
The point (17, 12) could cause the description of the data set to be overstated.
The point (17, 12) could cause the description of the data set to be understated.
The point (17, 12) shows that there is no relationship between the number of hours of darkness and the height of the plant.
Although (17, 12) is an extreme value, it should be part of the description of the relationship bet
Answers
Answer:
B. The point (17, 12) could cause the description of the data set to be understated.
Step-by-step explanation:
All other points on the scatter plot except point (17, 12), all follow a similar trend showing the negative relation between height of plants and darkness. If we are to consider just point (17, 12) alone when describing the data set, we might likely understate the relation between both variables.
Therefore, the statement that is true about the scatter plot is "B. The point (17, 12) could cause the description of the data set to be understated."
