A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process
The simplest expression is (2w)+(2*3w), because to calculate perimeter, you have to use this formula: 2length+2width.

10.35 according to chemistry . product
Answer:
a x (23a+5a^4 - 11)
Step-by-step explanation:
(a x (13a - 6a^4 - 2) + 10a^2 + 11a^5 - 9a
rewite the expression and remove any unnecessary parentheses.
a x (13a - 6a^4 -2) + 10a^2 +11a^5 - 9a
factor the expression.
a x (23a - 6a^4-2+11a^4-9)
connect like terms.

Answer:
Part (A)
and 
Part (B)
and 
Step-by-step explanation:
Consider the provided information.
Null hypothesis refers the population parameter is equal to the claimed value.
If there is no statistical significance in the test then it is know as the null which is denoted by
, otherwise it is known as alternative hypothesis denoted by
.
Part (A): The diameter of a spindle in a small motor is supposed to be 2.5 millimeters (mm) if the spindle is either too small or too large, the motor will not work properly.
Thus, the required null and alternative hypothesis are:
and 
Part (B) The nationwide average price of a certain brand of laundry detergent is $16.35 and Harry thinks that prices in Caldwell are lower than the rest of the country.
Thus, the required null and alternative hypothesis are:
and
