Answer:
b) statistic.
Step-by-step explanation:
In applied statistical work we rarely have the opportunity to measure entire populations, instead we make inferences about the populations from samples drawn, ideally randomly from the population. We usually want to know averages from whole populations, but use the average from a sample as our best guess at the population average. The unknown population average is called a parameter. The known sample average is called a statistic.
As a matter of convention, most statistical texts use greek symbols for population parameters and the English or Arabic letters for sample statistics. For example, a sample mean is often denoted as x-bar . Population means are denoted with the lower-case greek letter mu μ .
The answer is C
Start by making two equations with the given information
The first would just be their total cans:
E + A = 257
The second would be:
5E - A = 13
Then combine the equations to eliminate one variable.
6E = 270
E = 45
Now plug E back into one of the equations.
45 + A = 257
A = 212
Answer:
CD is the name of a ray in the drawing ⇒ 3rd answer
Step-by-step explanation:
A ray is a part of a line that has one endpoint and goes on infinitely in only one direction.
From the drawing:
∵ CA has C as a starting point
∵ A is a point on it
∵ Its direction from C to A
∴ CA is a ray
∵ CB has C as a starting point
∵ B is a point on it
∵ Its direction from C to B
∴ CB is a ray
∵ CD has C as a starting point
∵ D is a point on it
∵ Its direction from C to D
∴ CD is a ray
∵ CF has C as a starting point
∵ F is a point on it
∵ Its direction from C to F
∴ CF is a ray
From the answer:
CD is the name of a ray in the drawing
Answer:
35
Step-by-step explanation:
by adding three to the next number each time, the answer is 35
The ratio expression is £ 1.00 : £0.64 = 100:64
= 25:16
