Answer:
Step-by-step explanation:
The regular pentagonal pyramid has a base that is a regular pentagon and lateral faces that are equilateral triangles.
Calculate standard Z values for the given data:-
z = (80 - 110) / 20 = - 3/2 = -1.5
and z = (115 - 110) / 20 = 0.25
so we need Prob ( -1.5 < z < 0.25)
Using standard tables this comes to 0.5319 Answer
Answer:
b
Step-by-step explanation:
In a 30-60-90 right triangle, the hypotenuse is twice the length of the short leg.
The hypotenuse is AB and is 18.
The short leg is BC and is 9.
The only choice with BC = 9 is b.
Answer: b
Answer: I think the answer is C.
Step-by-step explanation:
In order to solve this problem you have to subtract 193 from 249 and divide the number by 7 to get 8. Since the bicycle costs more than $8, you need to put a open circle to represent that $8 is less than the arrow pointed to.
