Answer:
X=6
Step-by-step explanation:
If B and C equal 8 and is larger than x than x is a smaller number. D and C is 4 but its smaller than x so x has to be bigger. Your left with 3 choices 5, 6, and 7. Measure it and find out how big x is and its between 6 or 7. If any means they do decimals it can also be 6.5 so x=6 or x=7 or x=6.5
Daniel made an error in line 3. He wrongly divided the sum of sides and height. The area of the trapezoid is 42 cm².
<h3>What is the area of the trapezoid?</h3>
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides.
Area of a trapezoid = 1/2 x (sum of the lengths of the parallel sides) x height
- Line 1: A = 1/2 x (6) + (7 + 7)
- Line 2: A = 1/2 (6) (14)
- Line 3 : 3 x 14
- Line 4 : A = 42 cm²

Answer:
option a
Step-by-step explanation:
given that at a large Midwestern college, 4 % 4% of the students are Hispanic.
A random sample of 20 students from the college is selected.
We have each student is independent of the other to be hispanic
p = success = being hispanic = 0.04 while
q = failure = being non hispanic = 0.96
X - no of hispanics is thus binomial with p = 0.04 and n =20 (sample size)
Since X is binomial
Var(x) = npq = 0.768
Std dev (x) = Square root of variance = 
rounded off it gives 0.88
So option a is right
