Answer:
7/16
Step-by-step explanation:
Odds against = number of failures / number of successes
So number of failures = 9 and the number of successes = 7.
Probability = number of successes / number of total events
P = 7 / (7 + 9)
P = 7/16

We need to write the given statement in math terms:
y increased by 4
Recall that increased means that we are adding 4 to the previous number.
Then the mathematical expression is:
y + 4
The quantity y has been increased by 4 units.

What can be used to predict diameter, given family income
We can see (by observation) that the data on the table can only be represented on a scattered plot, and scattered plot uses regression equation for data prediction.
i.e.
--- equation of line of best fit
In this case;


<em>When the x value (income) is known, we can simply plug in the value in the above equation to get the y value (diameter)</em>
