17. 2x<16 x=7 or lower
All I can help you with is #17,
sorry that I can't answer the other 3.
I hope this helped! :-)

17) Let, the number = x
It would be: 2x ≥ 16
Divide both sides by 2,
2x/2 ≥ 16
x ≥ 8

19) Let, the number = x
5 < x/3 - 11 < 10
Add 11 to each side,
16 < x/3 < 21
Multiply 3 to the each side,
48 < x < 63

21) It would be: 1/0.06 < x< 1/0.02
[ 1 m = 100 cm] so, [6cm = 0.06 m & 2m = 0.02 cm]
17 < x < 50

23) Let, that number of books = x
It would be: 30 + 1.5x = 60
Subtract 30 from both sides,
1.5x = 30
Divide by 1.5,
x = 20

Hope this helps!

A circle with radius 4 inches is inscribed in an equilateral triangle. Find the area of the triangle.

LUCKY_DIMON [66]

The inscribed circle has its center at the point of intersection of the angle bisectors, which also happen to be the medians. Hence the altitude of the triangle is 3 times the radius, or 12 inches.

The side length of this triangle is 2/√3 times the altitude, so the area is

... Area = (1/2)·b·h = (1/2)·(24/√3 in)·(12 in)

... Area = 48√3 in² ≈ 83.1384 in²

Answer:

c) 2

d) 0.96

Step-by-step explanation:

We are given the following in the question:

$f(x) = 2x^{-3}, x > 1\\~~~~~~~= 0, x \leq 1$

a) probability density function.

$\displaystyle\int^{\infty}_{\infty}f(x) dx = 1\\\\\displaystyle\int^{\infty}_{-\infty}2x^{-3}dx = 1\\\\\displaystyle\int^{\infty}_{1}2x^{-3}dx\\\\\Rightarrow \big[-x^{-2}\big]^{\infty}_1\\\\\Rightarrow -(0-1) = 1$
