Axis of symmetry shows the min/max. its a max in this case and its at t=1.5
so the ans is <span>t = 1.5; it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground</span>
If she runs 7 miles every hour and runs a total of 11.2 miles, we can set this up as:
Where x represents the # of hours she ran for. Let's solve for x:
So, she ran for a total of 1.6 hours.
Answer:
y = -2x - 2
Step-by-step explanation:
The equation it's asking you to enter is in the form y=mx+b
where m is the slope
and b is the y-intercept
first, find the slope:
find a point on the graph and count how many cells you have to go down and over to get to the next point.
in this case, for each point, you have to go 2 down and 1 right.
The slope must be negative because the line is going across the graph from top-left to bottom-right
because slope is always rise/run, the slope of this line is -2/1, or just -2
Next, find the y-intercept:
look at the line on the graph where x=0
follow it down until you find a point
this is the y-intercept
in this case it is (0, -2)
but in equations we only use the y value of this point
So, the equation is y = -2x - 2
Hope this helps!
Sorry if I over-explained.
I tend to do that a lot.
Based on the scatter plot for this data, we can logically deduce that the association between them is a <u>positive association</u>.
<h3>What is a scatter plot?</h3>
A scatter plot can be defined as a type of graph which is used to graphically represent the values of two (2) variables, with the resulting points showing any association (correlation) between the data set.
<h3>Part A.</h3>
Based on the scatter plot for this data, we can deduce that the association between them is a <u>positive association</u> because the price and customer rating increases together.
<h3>Part B.</h3>
An example of a data point which would affect the appropriateness of using a linear regression model to fit all the data is car price of $4,601 and customer rating of 100.
<h3>Part C.</h3>
An example of a car that is cost effective and rated highly by customers is the one with a customer rating of 100 and sold at $3,500.
