False
because tan^2 45 = 1^2 = 1
and sec^2 x = 1/ cos^2 45 = (sqrt2)^2 = 2
so the sum = 3
Answer:
is neither significantly low nor significantly high.
Step-by-step explanation:
From the information given, we know that:
The mean is 
and the standard deviation is 
.
The range rule of thumb says that:
Applying these definitions, we get that
We note that is between 
and 
, which indicates is neither significantly low nor significantly high.
The shape at the top is a trapezoid with width 2 cm and lengths 4 and 8 cm.
Its area is
4+8
-------- 2 cm = 12 cm^2
2
The lower part consists of two congruent triangles. The area of a triangle is
A = (1/2)(b)(h). Here, A = (1/2) (4)(5.75) = 11.5, so the area of both triangles is 23 cm^2.
Thus, the total area is (12+23) cm^2, or 35 cm^2.
Answer:
8
Step-by-step explanation:
(24-12)/1.50=8
