The standard deviation of a particular sample is equal to the standard deviation divided by the square root of the sample size. That is,
The mean of a particular sample is equal to the mean of the set the sample was taken from. That is,
Answer: If Tom finished the race in 95 seconds and Robert finished 20 seconds before Tom, Robert finished in 75 seconds.
The expression that shows this is 95-20=75.

Answer:
<h3><u>Required Answer</u><u>:</u><u>-</u></h3>
Every number raised to a negative exponent will have a value smaller than 1.
<h3><u>Reason</u><u> </u><u>:</u><u>-</u></h3>
- It will only be negative if the number is negative with an odd exponent.
- what you're actually doing is dividing instead of multiplying.

Answer:
140 ml is needed to give 10.5g of Gantrisin
Step-by-step explanation:
In this question, we are asked to calculate how many milliliters liters will give a certain mass of Gantrisin.
Firstly, from the first values given, we can calculate the value if the density of the liquid.
Mathematically, the value of the density can be calculated by ;
Density = mass/volume = 1.5g / 20ml = 0.075 g/ml
Now for the second part of the question, we have the mass, but we do not know the volume. We can use the calculated density to know this.
We use the formula
volume = mass/density
Volume = 10.5g/(0.075g/ml)
Volume = 140 ml
