Answer:

Median equals 45. Mean equals 48

Step-by-step explanation:

To find the mean you add up all the numbers and divide by the number of numbers there are.

For median you put them from least to greatest and check them off from each side until you get a number in the middle.

chelsea takes the bus to school,but she walks home. the bus travels to the school at an average speed of 45 miles per hour. whil

jekas [21]

For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
the equation that will help find the time it takes chelsea to get to school on the bus is:
45 * t = 2.5 * (1-t)
Note: the equation will have one solution.

The nth term of a sequence is 2n2² - 4n+4 Work out the 8th term of the sequence. 8th term= Submit Answer Skip for Now

Marrrta [24]

The nth term of a sequence exists 2n2² - 4n+4 is 36.

<h3>What is PEMDAS' order of operations?</h3>

The order of operations exists as a rule that describes the right sequence of measures for estimating a math expression. We can recognize the order utilizing PEMDAS: Parentheses, Exponents, Multiplication, and Division (from left to right), Addition, and Subtraction (from left to right).

$$2*8*2^{2} - 4*8+4$

Follow the PEMDAS order of operations

Calculating the exponents, we get 2² = 4

$= 2*8*4 - 4*8+4$

= 64-32 +4

= 36

Therefore, the nth term of a sequence that exists 2n2² - 4n+4 is 36.
