a). (20 x 80) + (20 x 6) + (7 x 80) + (7 x 6)
Answer:
Infinate
Step-by-step explanation:
The normal distribution is dependent on the standard deviation and what the value of the mean is. But this then implies that a different standard deviation or a different mean leads to a different normal distribution. Making there many possibilities for normal distributions.
There are infinitely many possibilities for normal distributions as there are indefinitely many values possible for both the mean and standard deviation.
Answer:
55 - you multiplied 6 by 11 to get 66 so you multiply by 5 by 11 to get 55.
Answer: t = 9
Step-by-step explanation: 11 is greater than t so that means it can’t be t=11 or t=12
ANSWER
EXPLANATION
The given quadratic functions are;
and
A fractional coefficient indicates a horizontal stretch.
The smaller the coefficient, the wider the stretch for
and
Also
indicates a horizontal compression.
The higher the value the narrower the graph.
Therefore from widest to narrowest, we have,
