Answer:
Yeah, She can.
Step-by-step explanation:
Simply using 8/5
Answer:
1 and 1/8
Use common denominators:
5/8 - 4/8
so the answer is the 4th one
Answer:
58.61%
Step-by-step explanation:
Your total backyard is 18ft * 9ft = 162 ft^2
Your patio is 5ft * 8ft = 40 ft^2
Your Garden is 4ft * 7ft = 28 ft^2
Your walkway is 3ft * 9ft = 27 ft^2
Add all those areas together you have 95 ft^2
95 of 162 = 58.61%
Answer:
The error E = ± 4.04 %
Step-by-step explanation:
Solution:-
- The sample data is used to estimate the population proportion ( p ).
- The success p^ = success percentage = 40 %
- The confidence interval CI = 98%
- The sample size n = 800
- The margin of error E:
- The margin of error "E" for estimation of population proportion ( p ) is given by:
Where, Z-critical value is defined by the significance level:
P ( Z < Z-critical ) = α / 2
Where, α : Significance level
α = 1 - CI
P ( Z < Z-critical ) = (1 - 0.98) / 2
P ( Z < Z-critical ) = 0.01
Z-critical = 2.33
- The error E of estimation is:
- The error E = ± 4.04 %
The polynomial with those roots would be:
<span>y = (x + √5)(x - √5)(x - 3) </span>
<span>▬▬▬▬▬▬▬▬▬▬▬ multiply this out to get </span>
<span>y = (x² - 5)(x - 3) </span>
<span>y = x³ - 3x² - 5x +15</span>
