Answer:
The best way to show and explain direct proportional relationships is by graphing two sets of related quantities. If the relation is proportional, the graph will form a straight line that passes through the origin.
Answer:
91 cents
Step-by-step explanation: 3 times 25 is 75
3 times 5 is 15 then 1 so add to together
a.

is a proper joint density function if, over its support,
is non-negative and the integral of
is 1. The first condition is easily met as long as
. To meet the second condition, we require

b. Find the marginal joint density of
and
by integrating the joint density with respect to
:


Then


c. This probability can be found by simply integrating the joint density:


<h3>The given expression as single exponent is:</h3>

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

In exponents,
When the base is same, exponents can be added
Which means,

Therefore,

Thus the given expression as single exponent is:
