Answer:
86.2%
Step-by-step explanation:
25/29=0.862
Total tickets: 7
Popcorn costs: $5
total cost: $54
7x + 5 = 54
- 5 -5
7x = 49
49/7 = 7
Final Answer: x=7
15.3 cm- 9.46 cm= 5.84 cm.
The plant grew 5.84 cm from the beginning to the end of the month~
Answer: (a) (602.95,705.37)
(b) 33
Step-by-step explanation:
(a) Given : Sample size :
Sample mean :
Standard deviation :
Significance level :
Critical value :
The confidence interval for population mean is given by :-
Hence, the 95% (two-sided) confidence interval for true average level in the population of all homes from which the sample was selected.
(b) Given : Standard deviation :
Margin of error :
Significance level :
Critical value :
The formula to calculate the sample size is given by :-
Hence, the minimum required sample size would be 33.
Answer:
All values of x are solutions
Step-by-step explanation:
−15x+4 ≤ 109 OR −6x + 70 > −2
-15x ≤ 105 OR -6x > -72
-x ≤ 7 OR -x > - 12
x ≥ -7 OR x < 12
Answer
x ≥ -7 OR x < 12
All values of x are solutions
