Answer:
Random type
Step-by-step explanation:
Random sampling is like to put everyone's name into a hat and drawing out several names. In our case, that is basically what they did. The numbers of the 1069 adults were picked randomly.
In systematic sampling some samples are counted off. That is, every kth element is taken but in our case this didn't happen.
Convenience sampling uses the first people the surveyor runs into. which didn't happen because they call multiple samples.
Cluster sampling is accomplished by dividing the population into groups -- usually geographically. These groups are called clusters or blocks.
Stratified sampling also divides the population into groups called strata. However, this time it is by some characteristic, not geographically, which didn't happen in our case neither.
(2129-1727)/1727=0.232
The percentage of increase is 23%.
Answer:
A. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation:
A continuous data is any data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
Hence, the exact heights of different elephants represents a continuous data because the data can take on any value in an interval.
On the other hand, a discrete data is any data set in which the number of possible values are either finite or countable. Thus, a discrete data can only take on specific values. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
Answer:
x=4.6
Step-by-step explanation:
step 1 : calculate angle P since you know 2 angles
Step 2 : 57° - 90° = 180° [interior angles of a triangle ]
Step 3 : x/sin(33°) =7.1/sin(57°)
: x= 7.1Sin(33°)/sin(57°)
: x=4.6
