Answer:The importance of sample size calculation cannot be overemphasized. A research can be conducted for various objectives. A smaller sample will give a result which may not be sufficiently powered to detect a difference between the groups and the study may turn out to be falsely negative leading to a type II error.
Answer:
-288
Step-by-step explanation:
<h3>Given AP</h3>
<u>To find,</u>
- The sum of first 18 terms
<h3>Solution</h3>
<u>The first and 18th terms as per the formula</u>
- t(1) = 3 - 2 = 1
- t(18) = 3 - 18*2 = 3 - 36 = -33
- S18 = 1/2*18(1 - 33) = 9*(-32) = -288
<u>Answer is</u> -288
Answer:
Step 1: 798/ 8= 99.75
Step 2: 99.75 * 41 = 4089.75
The first significant figure is the first non-zero digit in a number. Therefore the first significant figure in 4089.75 is 4.
If the number following the value that you are rounding to (in this case, the first significant figure ie 4) is greater than or equal to 5, round up the value, ie add 1 to the number. Otherwise round down to the nearest whole number.
Since the number following the significant digit, 4, is zero we therefore round down the number.
Resulting in:
4000.
Therefore, your answer is 4000
Answer: -0.5
<u>Step-by-step explanation:</u>
the x-value for A is 0.
the x-value for B is -2.
The total distance from A to B is -2.
= -0.5
A + -0.5
= 0 - 0.5
= -0.5
