Answer:

The CPI is 178 .

Option (c) is correct .

Step-by-step explanation:

Formula

$CPI = \frac{(Current\ price\ of\ pair\ of\ jeans)\times 100}{Old\ price\ of\ pair\ of\ jeans}$

As given in the question

In 1983, a pair of jeans cost $66.35.

If a pair of jeans costs $118.10 today .

Put all the values in the formula

$CPI = \frac{118.10\times 100}{66.35}$

$CPI = \frac{11810}{66.35}$

CPI = 178 (Approx)

Therefore the CPI is 178 .

Option (c) is correct .

Hello I need help Finding the probability

Stolb23 [73]

Each petal of the region $R$ is the intersection of two circles, both of diameter 10. Each petal in turn is twice the area of a circular segment bounded by a chord of length $5\sqrt2$ , which implies the segment is subtended by an angle of $\dfrac\pi2$ . This means the area of the segment is

$\text{area}_{\text{segment}}=\text{area}_{\text{sector}}-\text{area}_{\text{triangle}}$
$\text{area}_{\text{segment}}=\dfrac{25\pi}4-\dfrac{25}2$

This means the area of one petal is $\dfrac{25\pi}2-25$ , and the area of $R$ is four times this, or $50\pi-100$ .

Meanwhile, the area of $G$ is simply the area of the square minus the area of $R$ , or $10^2-(50\pi-100)=200-50\pi$ .

So

$\mathbb P(X=R)=\dfrac{50\pi-100}{100}=\dfrac\pi2-1$
$\mathbb P(X=G)=\dfrac{200-50\pi}{100}=2-\dfrac\pi2$
$\mathbb P((X=R)\land(X=G))=0$ (provided these regions are indeed disjoint; it's hard to tell from the picture)
$\mathbb P((X=R)\lor(X=G))=\mathbb P(X=R)+\mathbb P(X=G)=1$

Given f(x)= -x^2+3x-4 and g(x)=2/3x +5 find f(g(-9))

scZoUnD [109]

Answer:

Step-by-step explanation:

First, you plug -9 into g(x) and you get g(-9) = - 1. After that, you solve f(-1), which you then reach the solution of 0 by solving.
