Answer:
250 sq ft
Step-by-step explanation:
Since the shorter side is along the street and the setback is 10ft from each side, the house is 50 ft wide
and 100 -20 -30 = 50 ft long
50 x 50 = 250 sq ft
Answer:
We have been given confidence interval 95%, mean 20 , data set 30 and standard deviation 3.
We will use the formula: 
Here,
Z-score value at 95% confidence interval is 1.96
On substituting the values in the formula to plug the values:
Now, we have a formula for marginal error:
Marginal error means your answer will be within that percentage only.
Say you have 3% marginal means your value will be within 3% real population 95% of the time.
Answer:
0
Step-by-step explanation:Velocity at t= 0s is 20m/s and the velocity at t= 10s is 20m/s.
a= 20-20/ 10s
a=0m/s
Answer:
angle 1= 76 degrees
angle 2= 61 degrees
Step-by-step explanation:
if you draw a line down the middle of the trapezoid and think of the two halves as parallel lines cut by a transversal, your angle are alternate interior, which makes them equal to each other or congruent. another way to find the measure is by finding the supplement to your angle that are already labeled.
just subtract 76 and 119 from 180 to find the supplements, which are 104 and 61, respectively. now that you have two angles labeled inside the trapezoid, you can use your quadrilateral rules to find the other ones. the rule in this case is "consecutive angles equal 180." so, the angle right below to angle R (119 degrees) is angle 2. using subtraction rule, 180-119= 61.
repeat for angle Q to find the measure of angle 1, 180-104= 76.
