Answer:
your answer is 0 because it's a horizontal line
Answer: A. True.
Step-by-step explanation:
A relationship is linear when the points on a scatterplot follow a somewhat straight line pattern. This is the relationship that we will examine. Linear relationships can be either positive or negative. Positive relationships have points that incline upwards to the right. As x values increase, y values increase.
Answer:
Step-by-step explanation:
radius(r)=diameter/2
=10.4/2
=5.2 cm
circumference of a circle =2πr
=2*3.14*5.2
=32.656
=32.7
Finding two geometric means between 10 and 125:
a 1 = 10, a 4 = 1250
a 4 = a 1 * q^3
1250 = 10 * q^3
q^3 = 1250 : 10
q^3 = 125
q = 5
a 2 = 10 * 5 = 50
a 3 = 10 * 5² = 10 * 25 = 250
Answer: The two geometric means are: 50 and 250, since 10, 50, 250 , 1250 forms a geometric sequence.
Answer:
Part A:
Type of Sampling: Convenience Sampling
It is a non-probability sampling technique. Though it is easy to carry out, it might be biased and can lead to under - representation or over - representation of particular groups within the sample. Since the sampling frame is not known and the sample is not chosen randomly, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied.
Part B.
The committee can implement this method as follows:
Step 1: Assign Serial Number to each and every student of the total of 2,500 student names.
Step 2:Using Random Number Generator App, obtain 400 Random numbers.
Step 3; The 400 numbers got in Step 2 form the desired Sample of 400 students out of 2,500 students.
