Answer:
(3,7), (3,8), (3,9), (3,10) is not a function.
Step-by-step explanation:
A function is defined as a relation in which each input value has only a single output value.
This means that for each value there should be only one
value. If this criteria is not fulfilled then the relation cannot be called a function.
For the given set of points, we notice that for , which shows there are many y-values o for a single x-value. This means there are many outputs for a single input. This disqualifies it to be a function.
Thus, (3,7), (3,8), (3,9), (3,10) is not a function.
Answer:
c = 4.79 feet
Step-by-step explanation:
Given question is incomplete without a picture; find the question with the attachment.
Two poles AD and DB of same length are leaning against each other.
Distance between the poles (AB) = 45 feet
m(∠ADB) = 180°- (60 + 50)°
= 70°
By sine rule,
= 36.68 ft
Similarly,
DB =
= 41.47 ft
Now c = DB - AD
= 41.47 - 36.68
= 4.79 feet
Answer:
The Pearson's coefficient of correlation between the is 0.700.
Step-by-step explanation:
The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.
The formula to compute correlation between two variables <em>X</em> and <em>Y</em> is:
The formula to compute covariance is:
The formula to compute the variances are:
Consider the table attached below.
Compute the covariance as follows:
Thus, the covariance is 75.
Compute the variance of X and Y as follows:
Compute the correlation coefficient as follows:
Thus, the Pearson's coefficient of correlation between the is 0.700.
