Answer:
The answer is C.
Step-by-step explanation:
As you can see, It won't be a square because the bottom is 4 units long and the triangle is an estimated 3 units tall, so you can cross those two answers out. Next, you can look at the first answer. What is obvious, the triangle is definitely not double a rectangle what has the same basic measurements as the triangle. Answer C is the only one that is logical.
Answer: (29.35, 40.95)
Step-by-step explanation:
Formula to find the confidence interval for population mean :-
, where 
= sample mean.
z*= critical z-value
n= sample size.
= Population standard deviation.
As per given , we have
n= 37
Using z-table, the critical z-value for 95% confidence = z* = 1.96
Then, the confidence interval for the population mean will be :
Hence, a 95% confidence interval for the population mean = (29.35, 40.95)
I think the answer is 2.07, I’m not positive so I’m really sorry if I’m wrong
Answer:
x = 16 2/3
Step-by-step explanation:
The altitude divides the triangle into similar triangles. We can form the ratio between the hypotenuse and the short leg for two of the triangles. Those ratios will be a proportion:
10/6 = ((x-6) +6)/10
100/6 = x . . . . . multiply by 10 and simplify
x = 16 2/3
The answer will be close to 470 1/2
