Answer:
2 is the bigger number
Step-by-step explanation:
Answer:
<u>The correct answer is B. Exponential form.</u>
Step-by-step explanation:
The exponential form was developed to express repeated multiplications and to make it easier to write long numbers. The exponential notation has two parts. The base, as the name says, is the number below. The other part of the notation is a small number written on the superscript to the right of the base, called an exponent. We will use an example to learn about the exponential form or notation.
2³
In this example the base is 2. This means that 2 is a factor, and that it will be multiplied by itself a certain number of times. The precise number of times is given by the exponent, the number in the superscript. In this case, the exponent is 3, which means that base 2 will be used as a factor 3 times. So 2³ means 2 • 2 • 2 and the result is 8.
Answer:
The mean is 70.8.
Step-by-step explanation:
Finding the arithmetic mean, or average, can be found by adding up all the numbers divided by the total count of those numbers.
So, we have :: 60, 67, 71, 76, 80.
These numbers added together = 354.
There are 5 numbers listed.
354 / 5 = 70.8.
Answer:
-1
Step-by-step explanation:
All you have to do is fill in -3 in for y and you will find your x.
I got; -1 Because
2x-(-3)=1
2x+3=1
-3 -3
2x/2=-2/2
x=-1
Answer:
Step-by-step explanation:
Using the FOIL method:
Simplify the expression by squaring:
Now we can use the Foil method:
First, Outside, Inside, Last
Multiply the first terms within each grouping:
Insert as the first term:
Now multiply the outside terms in each grouping:
Insert as the next term:
Now multiply the inside terms:
Insert as the third term:
Now multiply the last terms in the grouping:
Insert as the last term:
Simplify by combining like terms:
