Answer:
Step-by-step explanation:
1) (1÷5)*5*14 = 
= 1*14 = 14
2) 6 + 4(19 - 5) = 6 + 4 * 14
= 6 + 56
= 62
Or
Use distributive property. a(b+c) = a*b + a*c
6 + 4( 19 - 5) = 6 + 4* 19 - 4*5
= 6 + 76 - 20
= 82 - 20
= 62
3) 5(14- 5) + 6 (3 +7) = 5 * 9 + 6 *10
= 54 + 60
= 114

Answer: (6.4005, 4.925)
Step-by-step explanation: n = sample size = 68
σ = population standard deviation = 0.35 hours
x = sample mean = 5.8
We are to construct a 95% confidence level for population mean.
This is given below as
Confidence interval = x ± Zα/2 × σ/√n
Where Zα/2 = critical value for a 2 tailed with 5 percent level of significance (that's α=5%) = 1.96
Note that level of significance + confidence level = 100, hence a 95% confidence level will give a 5% level of significance
For the upper limit of the 95% confidence interval, we have that
x + Zα/2 × σ/√n
5.8 +1.96(0.38/√68)
5.8 + 1.96 (0.046)
5.8 + 0.0875
= 6.4005
For the lower limit of the 95% confidence interval, we have that
x - Zα/2 × σ/√n
5.8 - 1.96(0.38/√68)
5.8 - 1.96 (0.046)
5.8 - 0.0875
=4.925

}
<em>Range:</em> {

}
Step-by-step explanation:
To find the domain, find where the function is defined. The range is just the set of values that correspond with the domain.
