The maximum height is 64ft and the ballon is only in the air for 2 seconds
Answer:
x
Step-by-step explanation:
f(x) = (x-1)/3
g(x) = 3x+1
f(x) °g(x) =
Substitute g(x) in for x in the function f(x)
f(x) °g(x) = (g(x) -1)/3
= (3x+1 -1)/3
= 3x /3
=x
Answer:
3. 17x + 5 = 90° ( alternate exterior angles are equal)
=> 17x + = 90 – 5
=> 17x = 85
=> x = 85/17
=> x = 5
4. 63° + c + 110° + 75° + 50° = 360 °
=> c + 298° = 360°
=> c = 360° – 298°
=> c = 62 °

Step-by-step explanation:
Answer:
68% of the incomes lie between $36,400 and $38,000.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $37,200
Standard Deviation, σ = $800
We are given that the distribution of SAT score is a bell shaped distribution that is a normal distribution.
Empirical rule:
- Almost all the data lies within three standard deviation of mean for a normally distributed data.
- About 68% of data lies within one standard deviation of mean.
- About 95% of data lies within two standard deviation of mean.
- About 99.7% of data lies within three standard deviation of mean.
Thus, 68% of data lies within one standard deviation.

Thus, 68% of the incomes lie between $36,400 and $38,000.
