Answer:
Option c. is correct
Step-by-step explanation:
The standard deviation is a measure of the amount of dispersion in a set of values.
Mean of a normal distribution (m) = 154
Standard deviation (s) = 15
z-score = 2.2
To find: value (x) that has a z-score of 2.2
z-score is given by
Put
Option c.is correct
Answer:
6.8 nearly 7
Step-by-step explanation:
beacuse mean is sum of all terms in a data/number of terms in the data
Answer:
b. a specific value of the dependent variable for a given value of the independent variable
Step-by-step explanation:
In correlation analysis, one can measure the strength of the relationship between two or more variables.
The aim of this analysis is to understand that in case of any change in the <em>independent variable </em>there is also change in the<em> dependent variable</em> or not.
The most common correlation method used is Pearson correlation, which measures <em>linear relationships</em> between variables.
We can find the midpoint of any line segment using the midpoint formula: M=(x1+x2/2,y1+y2/2). Essentially, the midpoint formula finds the average of two points. If we use B and the first point and C as the second, when we plug in our values we would have M=(5-4/2,9-5/2). This can be simplified to M=(1/2,4/2) or M=(1/2,2) which is the final answer.
I hope this helps.
Answer:
18.84
Step-by-step explanation:
1. The formula for volume of a cone is (r^2x3.14xh)/3
2. So it would be 3^2x3.14x2 divided by 3
3. that would be 18.84
