Answer:
Approximately : 135
Step-by-step explanation:
60sec x 3 = 180sec
45 x 3 = 135
Answer:
The possible rational roots are
Step-by-step explanation:
We have been given the equation 3x^3+9x-6=0 and we have to list all possible rational roots by rational root theorem.
The factors of constant term are 
The factors of leading coefficient are 
From ration root theorem, the possible roots are the ratio of the factors of the constant term and the factors of the leading coefficient. We include both positive as well as negative, hence we must include plus minus.
Answer:
The correct conclusion is;
d) Additional information is needed to draw a proper conclussion
Step-by-step explanation:
The given parameters are;
When listening to music;
Physiological measure Critical t > Test statistic Accept H₀
Anxiety measure Critical t < Test statistic Reject H₀
When composing music;
Physiological measure Critical t > Test statistic Accept H₀
Anxiety measure Critical t > Test statistic Accept H₀
When the test statistic is larger the critical 't'
Therefore, the test suggest that there is no difference between physiological and anxiety influence of composing music on pediatric asthma patients
There is sufficient statistical evidence to suggest that listening to music has an influence on the anxiety of pediatric asthma patients however, the nature of the influence is not specified and more information is needed to draw a proper conclusion
