Answer:
1,54,&2
Step-by-step explanation:
To find the area of the Trapezoid you add the top base and the bottom base then divide them by 2 is y X+Y is the Trapezoid. remember don't multiply all the sides. you have to use the formula to find the Area of the Trapezoid. A=a+b/2(h) A=9+17/2(6)A=78
So let us set up the equations:
d = rt
d = 12t and plug in r = 12
so after t hours, the faster runner is 12t miles which is
for the faster runner.
d = rt
d = 8t plug in r = 8
so after t hours, the slower runner has 8t miles.
Now if you want to get the distance, simply subtract:
12t – 8t = 4t
Since we need to get the distance of ¼ mile, meaning:
12t – 8t = ¼
= 4(12t – 8t) = 4 x 1/4 -> multiply both sides by the lcd
to clear the fractions
= 48t – 32t = 1
=16t = 1
Get t by dividing both sides by 16 to isolate t.
So the answer is 1/16 which is about 0.0625.

Answer: 20
Step-by-step explanation:
Formula to find the minimum sample size(n) when prior population standard deviation is known.
, where E = Margin of error , = Critical z-value for c confidence interval.
Given : E = 225 g , g
Critical z value for 90% confidence = 1.645
Now,
Hence, the required minimum sample size = 20
