Option A:
Solution:
ABCD and EGFH are two trapezoids.
To determine the correct way to tell the two trapezoids are similar.
Option A:
AB = GF (side)
BC = FH (side)
CD = HE (side)
DA = EG (side)
So, is the correct way to complete the statement.
Option B: 
In the given image length of AB ≠ EG.
So, is the not the correct way to complete the statement.
Option C: 
In the given image length of AB ≠ FH.
So, is the not the correct way to complete the statement.
Option D: 
In the given image length of AB ≠ HE.
So, is the not the correct way to complete the statement.
Hence, is the correct way to complete the statement.
Answer:
$10.12
Step-by-step explanation:
Step one:
given data
we are told that the cost of binoculars is $155.75
and also the sales tax is 7%
Step two:
We want to first solve for the sales tax which is 7% of $155.75
=7/100* 155.75
=0.070*155.75
=10.12
Cassie will pay a tax of $10.12
Also Cassie will pay a total amount of
= 155.75+10.12
=$165.87

Step-by-step explanation:
Answer:
the probability that the sample variance exceeds 3.10 is 0.02020 ( 2,02%)
Step-by-step explanation:
since the variance S² of the batch follows a normal distribution , then for a sample n of 20 distributions , then the random variable Z:
Z= S²*(n-1)/σ²
follows a χ² ( chi-squared) distribution with (n-1) degrees of freedom
since
S² > 3.10 , σ²= 1.75 , n= 20
thus
Z > 33.65
then from χ² distribution tables:
P(Z > 33.65) = 0.02020
therefore the probability that the sample variance exceeds 3.10 is 0.02020 ( 2,02%)
multiply 12,800 x 15 = 192,000 then divide 192,000 by 100 = 1,920 so the answer is $ 1,920. Hope this helps!
