The answer isc because complementary angles add up to 90 degrees
Answer:
Step-by-step explanation:
By looking at the graph I notice an open circle at (-4, -5) which means the function is not evaluable at -4, this restricts the domain.
The Domain of a function represents the set of values for which the function has an output.
The Range of a function is the set containing all the possible values associated with all input.
Domain in interval notation: (-4, 3]. The parenthesis denotes that the interval does not contain the extreme point -4. The brackets are the opposite.
Domain in set builder notation: ![$\{x |-4](https://tex.z-dn.net/?f=%24%5C%7Bx%20%7C-4%3Cx%20%5Cleq%203%20%5C%7D%24)
Range in interval notation: (-5, -3]
Range in set builder notation: ![$\{y |-5](https://tex.z-dn.net/?f=%24%5C%7By%20%7C-5%3Cy%20%5Cleq%203%20%5C%7D%24)
Hi there!
<u>Set A has a LARGER standard deviation. </u>
A set's standard deviation is equivalent to:
![\sigma = \frac{\sqrt{\Sigma (x - \mu)^2 }}{n-1}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Cfrac%7B%5Csqrt%7B%5CSigma%20%28x%20-%20%5Cmu%29%5E2%20%7D%7D%7Bn-1%7D)
σ = standard deviation
x = value
μ = mean
n = # of observations
Basically, standard deviation is calculated using how far apart EACH value is from the set's mean. If more values are FARTHER away from the mean, the standard deviation increases and vice-versa.
Set A has a GREATER RANGE and its values are farther from 13 on both sides compared to Set B which has a SMALLER RANGE and its values are closer to 13.
Therefore, Set A will have a larger standard deviation.
Y=mx+b now just re do them
Answer:
Value = 44,0000(0.75)^t
Where t = number of years
Value after 4 years = 44,000 (0.75)^4
