Answer:
g=8 and f=6
Step-by-step explanation:
Area of ABCD=f×g
or,48=fg
or,48/g=f.........(i)
we have,
AD=BC=f
Now,
Area of ABCD+Area of ADE=Area of ABCE
f×g+1/2×DE×AD=60
or,48/g×g+1/2×4×f=60
or,48+2f=60
or,2f=12
therefore,
f=6
And,
48/g=6
or,48=6g
therefore,
g=8
- <em>margin of error tells you how many percentage points your results will differ from the real population value. </em>
<h2><em>hope</em><em> it</em><em> helps</em><em>!</em></h2>
Step-by-step explanation:
- <em>For example, a 95% confidence interval with a 4 percent margin of error means that your statistic will be within 4 percentage points of the real population value 95% of the time</em>
Answer:
35
Step-by-step explanation:
Since the two sides are equal in a parallelogram angle B = y ,so we have angle to be equal to 145°
We sum both angles and divide from
360° - [145° +145°]
360° - 290° = 70
Since the left sides( X And Z) are equal then we divide what we got into 2
70 ÷ 2 = 35
therefore angle X equals 35
Answer:
The water in the tank filled to capacity lasts 20 days.
Step-by-step explanation:
Total number of students in the hostel = 300
The average need of water per day = 36,000 L
The dimensions of the tank = 10 m × 8 m × 9 m
Now, the capacity of the tank = LENGTH X WIGHT X HEIGHT
= 10 m × 8 m × 9 m = 720 cubic meters
Now, 
⇒
So, the capacity of the tank = 720,000 L
and the average usage of water by 300 students = 
⇒
or, number of days = 20
Hence, the water in the tank filled to capacity lasts 20 days.
