Answer:
Solving 14t-3t we get 22 and 3t-14t we get -22
So, 14t-3t is not equivalent to 3t-14t.
Step-by-step explanation:
We need to explain weather 14t-3t is equivalent to 3t-14t. Support your sender by evaluating the expression for t=2.
<em>Equivalent expressions are those that have same values for any value of variable substituted.</em>
Now, We check if our expressions are equivalent, by evaluating the expression for t=2.
If they are equivalent, they would have same result after evaluation.
First, put t=2 into 14t-3t

Now put t=2, into 3t-14t

For solving 14t-3t we get 22 and 3t-14t we get -22
So, 14t-3t is not equivalent to 3t-14t.
Answer:
The approximate area of the circle is <u>2462 centimeters²</u>.
Step-by-step explanation:
Given:
John and Becky measured the circle-shaped part of a sun they drew on the sidewalk. The diameter of the circle is 56 centimeters.
Now, to get the area of the circle approximately.
Diameter of the circle = 56 centimeters.
<em>So, the radius </em><em>(r)</em><em> of the circle</em> = 
Using 3.14 for π.
Now, to get the area of circle by putting formula:

<u><em>Approximately the area of the circle = 2462 centimeters².</em></u>
Therefore, the approximate area of the circle is 2462 centimeters².
The area of a triangle can be shown in the equation Area=1/2(base)(height). Since you are given area and height, you can just solve for the base.
6=1/2(base)(4) ---> 6=2(base) ---> base=3
Answer:
Expectation number of books a customer will purchase = 1.3
Step-by-step explanation:
x : 0 1 2
p(x) :0.2, 0.3, and 0.5
Expectation
E(X) = ∑x P(x)
= 0 X 0.2 +1 X 0.3+ 2 X 0.5
= 1.3
Expectation E(X) = 1.3
Expectation number of books a customer will purchase = 1.3
