Answer:
170 mph
Step-by-step explanation:
Let x mph be the plane's speed.
If the car travels 110 mph slower than the plane, then the car's speed is x - 110 mph.
<u>Plane:</u>
Speed = x mph
Distance = 1,020 miles
Time = t hours
<u>Car:</u>
Speed = x - 110 mph
Distance = 360 miles
Time = t hours
A plane can fly 1020 miles in the same time as it takes a car to go 360 miles, so
Cross multiply:
25 times 3 divided by 10 is 7.5 so the mural has to be 7.5 feet
Answer:
Therefore, for the case above; the Alternative hypothesis is;
H1: is not equal to $50,000.
H1: ≠ $50,000.
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is not different than its mean.
While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above; the Alternative hypothesis is;
H1: is not equal to $50,000.
H1: ≠ $50,000.
Answer:
59°
Step-by-step explanation:
as angle 6 and 7 are co interior angle
121°+ x°=180°
x=180-121
x=59°
