Question 60:
The answer is B. 25.57.
Mean is calculated by adding up all the values of a data set, and then dividing that sum by the amount of values.
25, 32, 16, 21, 30, 18, 37=179
179÷7=25.57
Question 61:
The answer is A. 102.
Mode is the number in a data set that appears most often. 102 shows up twice, while the other values only appear once. So 102 is the mode.
Answer:
n = 3.68
Explanation:
We know that:
1 mg is equivalent to 0.0001 dag
To convert 38600 mg to dag, we will simply use cross multiplication as follows:
1 mg ..............> 0.0001 dag
38600 mg ......> n
n = (38600*0.0001) / 1
n = 3.68
Hope this helps :)

Answer:
The correct answer is a. $2275.28; b. 17.04 years
Step-by-step explanation:
Principal to be invested is $2000
Interest rate (r) per year is 6.5 quarterly.
Interest is calculated compoundly.
a. Time (t) for the investment is given to be 2 years.
Amount after two years is = Principal × 
where the value of n is 4.
⇒ A = 2000 × 
⇒ A = $2275.28.
b. Now the value of A is given to be triple the principal = $ (3 × 2000).
Therefore we need to find the value of t.
⇒ 3 × 2000 = 2000 × 
⇒ ㏑ 3 = 4t × ㏑ ( 1.01625)
⇒ t = 17.04
Therefore it would take 17.04 years for the principal to triple.
Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.
