Answer:
Step-by-step explanation:
Area = (17×35) - (6×15) = 595 - 90 = 505 ft²
Answer:
1/2
Step-by-step explanation:
It's the first one because all the y's are the same number. That means that when you graph the chart you would get a horizontal line. Horizontal lines on graphs always have a slope of zero....unlike a verticals slope is undefined.
Answer:
The probability is 0
Step-by-step explanation:
Since proportion of time spent on mowing will be 200/400 = 0.5, there will be no chance that the true proportion of time spent mowing is exactly equal to the sample proportion. Where true proportion is 200 and sample is 400 . So the probability is 0.
Answer:
30° or 60°
Step-by-step explanation:
Range of a projectile on level ground is:
R = v₀² sin(2θ) / g
Given R = 15 m and v₀ = 13 m/s:
15 m = (13 m/s)² sin(2θ) / (9.8 m/s²)
sin(2θ) = 0.870
2θ = 60.4° or 119.6°
θ = 30.2° or 59.8°
Rounded, the launch angle required is either 30° or 60°.
