The answer is :X^2 + 7x + 12
The mistake made was when expanding they added 3 and 4 together instead of multiplying it
Answer:
The height of the tower=2,702 feet
Step-by-step explanation:
The angle of elevation is the angle between the horizontal level ground and the hypotenuse. Since we have the horizontal distance, we can use this to estimate the vertical height from the base of the tower using the expression below;
Tan∅=h/b
where;
∅=the angle of elevation
h=vertical height of the tower
b=the distance from the base of the tower to the point on level ground
In our case;
∅=27.1°
h=unknown
b=5280 feet
replacing;
Tan 27.1=h/5280
h=5,280×Tan 27.1
h=2,701.91 feet
2,701.91 to the nearest foot=2,702 feet
The height of the tower=2,702 feet
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.
