What is the 3rd term in the sequence?​
makvit [3.9K]

Answer:

6

Step-by-step explanation:

To find the third term substitute n = 3 into the n th term formula

a(3) = \frac{3}{2}(-2)^{3-1}

      = \frac{3}{2}(-2)^{2}

      = \frac{3}{2} × 4 = 6

given a rectangle of length a and width b if A and B are both rational numbers would the perimeter be irrational or rational? Gi
Kitty [74]
The perimeter would be rational due to both the width and length being rational numbers. A rational number is a number that can be written as a fraction such as 8 it can be written as 8/1, but a irrational would be a decimal number which in this case there would be none because both length and width is rational number. For example, Lets say the width is 8 and the length is 10. once both are written into fraction form such as 8/1 and 10/1 we add them to get a perimeter of 18.

The test scores of five students for the first two test of the semester are shown in the table below.
Mekhanik [1.2K]

Answer:

A

Step-by-step explanation:

Take test score from Test 1 and add them all together and divide by the number of test

ex) 77+82+69+85+93=406

    406/5= 81.2

Then repeat with Test 2

ex) 75+76+71+68+72=362

    362/5= 72.4

Therefore the MAD of Test 1 > MAD of Test 2
