To multiply one number ( a multiplicand ) by another ( a multiplier ) means to repeat a multiplicand as an addend times. The result of multiplying is called a product. The operation of multiplication is written as: 12 x 6, or 12 * 6
Multiply 12 by 6
6 is called the Multiplier
12 is called the Multiplicand
72 is called the Product
Therefore, a multiplicand and a multiplier are called factors or multipliers.

The answer is 8.2×10^5 . All you have to do is move the decimal place over till there is only one number after the decimal.
Answer:
The number of heads observed is 121.14 heads
Step-by-step explanation:
The formula for the z-score of a proportion is given as follows;
Where:
= Sample proportion
p = Population success proportion = 0.5
q = 1 - p = 1 - 0.5 = 0.5
n = Number in of observation = 200
z = 2.99
Hence, we have;
Therefore;
= 0.6057
∴ The number of heads observed = 200 × 0.6057 = 121.14 heads.

Apply the Keep Flip Change rule here
1/4 has been kept the same
The sign has been changed
The other fraction needs to be flipped
Thus, z = -2/7
