Answer:
22 units
Step-by-step explanation:
The formula for the area of a trapezoid is A = 
where a and b are the <u>bases</u> and h is the <u>height</u> of the trapezoid.
In this case, the numbers that will be replacing a and b will be 4 and 7, making the equation look like this: A = 
.
Now, you have to determine the height of the trapezoid, which in this case is 4 units. The equation will now look like this: A = 
.
You can solve from here like so:
A = 
A = 5.5(4)
A = 22
sorry that took long :3))
I got the measurements like 4, 7, and the other 4 from rotating the shape to have the longer side on the bottom.

Answer: Correct critical value = 2.2622
Step-by-step explanation:
Confidence interval for population mean when population standard deviation is unknown:
, where 
= sample mean, n= sample size, s= sample standard deviation, 
= two-tailed t value.
As per given: n= 10
degree of freedom : df = n-1=9
Critical t-value : 
So, the 95 percent confidence interval estimate for the mean :
The 95 percent confidence interval estimate for the mean:(190.14, 295.06)
Answer:
0.7.
Step-by-step explanation:
x^2 = 0.7x
x^2 - 0.7x = 0
x(x - 0.7) = 0
x = 0, 0.7.
