Answer:
. B. If the distribution of the sample means is normally distributed, and greater than30, then the population distribution is normally distributed
Area of Trapezoid is = 1/2 x height x (base1 + base2)
Here, Area = 98, base1 = 8, base2 = 20 and height = unknown (x)
So, 1/2 x height x (8+20) = 98
==> 1/2 x height x 28 = 98
==> height x 14 = 98
==> height = 98/14
==> height = 7 units
So, the final answer is --> the value of x = 7 units
9.42 Units
Step-by-step explanation:
Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:
270/360; 360 being the total angle measurement of a circle
270/360 simplifies to 3/4
The fraction represents how much of the circle that arc covers
Now we have to find the circumference which would be
2(3.14)r
r = 2 therefore: 2(3.14)2 = 12.56
Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length
Which gives us 9.42
