1. incorrect
odd number multiplied by odd number is still an odd number, 3 being an odd number when multiplied by 3 is 9 which is an odd number
2.incorrect
this states that if 6 is less than 7, which is true, then 4 is greater than 7, which is incorrect. The 2 statements are not related
3.correct
6 is divisible by 3, 6/3 = 2, this means that 6 can be divided by 3 without giving a remainder.
10 is a multiple of 2. multiples of 2 in other words are numbers that are divisible by 2. Since 2*5 = 10, its a multiple of 2.
4.Incorrect.
Average of data is the sum of the data values divided by the number of values there are, so the average value cannot be greater than the largest data value.
Also second statement too is wrong, there are some instances when the data values all may be equal e.g.: 45,45,45, then the average of these data are also 45, hence the average cannot always be lesser than the largest data value. Average should be equal to or less than the largest data value.
5. Incorrect
the slope is the rate of change m(gradient) = change in y/change in x. however the y intercept is not the initial value. Intercept is merely the point at which the graph cuts the y axis, not its initial value.
6.incorrect
sum of the interior angles of a triangle is 180°. since there are 3 equal angles, 180°/3 = 60°. therefore each angle is 60°.

<u>Looking for key words in the problem:</u>
"At Most" represents important key words, meaning the maximum amount of hotdogs that are at the barbecue.
<u>Inequality:</u>
h 
16 represents the maximum amount of hotdogs that has to be at the barbecue, also represents less than 16 can be cooked.
Answer:
a) The symbol for sample standard deviation is S
b) The symbol for population standard deviation is б (sigma)
c) The symbol for sample variance 
d)The symbol for population variance is 
Step-by-step explanation:
Step 1:-
Population:- Population consists of the total of the observations with which we are concerned.
Parameters:- The statistical constants of the population namely mean , variance
and standard deviation 'б '
Sample:- A sample is a subset of a Population
statistics:-
he statistical constants of the sample namely mean , variance
and standard deviation 'S '
step2:-
a) The symbol for sample standard deviation is S
b) The symbol for population standard deviation is б (sigma)
c) The symbol for sample variance
d)The symbol for population variance is
