The lifespans of crocodiles have an approximately Normal distribution, with a mean of 18 years and a standard

antiseptic1488 [7]

Answer:

0.0618.

Step-by-step explanation:

14-18= -4

-4/2.6= -1.538

Use the Z-table to find the proportion that aligns with 1.54 (round up because of the 0.008)

The intersection between 1.5 and 0.04 will be 0.0618.

y=f(x) is odd (f(-x)=-f(x)) and f(x>0) = x^2-5x-12, x is not = to 0. What points does the line f(x)=12 go through.

solmaris [256]

<span>f(x<0)=-f(x>0)=-x^2+5x+12 When x>0, x^2-5x-12=12, x=8, y=12 Therefore, f(x)=12 goes through point (8,12).</span>

Suppose a triangle has sides a, b, and c, and the angle opposite the side of length b is obtuse. What must be true?

anyanavicka [17]

Answer: D. $a^2 + b^2 < c^2$

Step-by-step explanation:

In the given figure, we have an obtuse triangle which has sides a, b, and c, and the angle opposite the side of length b is obtuse.

∵ In a triangle, the side opposite to the largest angle is largest.

Thus, the largest side in then given obtuse triangle= c

The Pythagorean inequalities theorem says that If a triangle is obtuse than the square of the largest side is greater than the sum of square of other two sides.

Therefore, we have

$a^2 + b^2 < c^2$
