Answer:
D: How many hours did you spend watching TV today?
Step-by-step explanation:
Statistical questions can be identified by the fact that they can have multiple answers. This question could be answered in many different ways. "Did you watch four hours of TV today?" is a yes or no question (which makes it non statistical), "Did you watch TV today?" is the same way. "Did you watch five or six hours of TV today?" also only has two possible answers, which means it is non statistical.
D: How many hours did you spend watching TV today? is the only option that has multiple possible ways of answering
Answer:
Step-by-step explanation:
To figure out this problem we need to divide 6 1/2 by 4.
Convert any mixed numbers to fractions. Then your initial equation becomes:
Applying the fractions formula for division:
Simplifying 13/8, the answer is:
Answer:
yes
Step-by-step explanation:
Answer:
y = 0
Step-by-step explanation:
The given sinusoidal equation is
The general form of the sin function is presented as follows;
y = A·sin(B·(x - C)) + D
Where;
A = The amplitude
The period, T = 2·π/B
The frequency, f = B/2·π
C = The horizontal shift
D = The vertical shift
By comparison with the given sine function, we have;
The amplitude, A = 2
The frequency, f = B/2·π = π/2/(2·π) = 1/4
The frequency, f = 1/4 Hz
C = The horizontal shift = 3/(π/2) = 6/π
The vertical shift, D = 0
Given that the mid line of the parent function, sin(x), is the line y = 0, and that the vertical shift is 0, the midline of the function, , is therefore, the line;
y = 0.
