Answer:
descriptive and inferential statistics.
Step-by-step explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
Focusing on describing or explaining data versus going beyond immediate data and making inferences is the difference between descriptive and inferential statistics because descriptive statistics focuses on describing or explaining data contained in a population or obtained as a sample while inferential statistics is solely based on drawing an inference from a sample or population.
Answer:
$80,000
Step-by-step explanation:
40%___$32,000
100%___X=$80,000
(100*32,000)/40 = 80,000
Answer:
- 6 ft per flip
- 14 ft from A to B
Step-by-step explanation:
<h3>a.</h3>
If we assume that the first two flips are to the right, for some flip distance f, Croakie will land at ...
B = A + 2 +2f
He will land back at A (the origin) after 1 flip and a slide of 8 ft to the left:
B -f -8 = A
Subtracting A from both equations and substituting for B-A, we have ...
B -A = 2 +2f
B -A -f -8 = 0
(2 +2f) -f -8 = 0 . . . . substitute for (B-A)
f -6 = 0 . . . . simplify
f = 6 . . . . . add 6
The length of a flip is 6 feet.
__
<h3>b.</h3>
B -A = 2 +2f = 2 +2(6) = 14
The distance between A and B is 14 feet.
Answer:
The volume to the cylinder is 433.8 in³
Step-by-step explanation:
To solve this problem we have to know that to calculate the volume of the cylinder we have to multiply the base by the height.
The base of a cylinder is circular, so we have to calculate its area with another formula.
The area of a circle is calculated with the following formula:
r = d/2
r = 8.2 / 2
r = 4.1 in
a = π * r ²
a = 3.14 * 4.1²
a = 52.7834 in²
The volume of a cylinder is calculated with the following formula:
h = 8.2 in
v = a * h
v = 52.7834 in² * 8.2 in
v = 432.82388
round to de nearest tenth
v = 433.8 in³
