Answer:

The CPI is defined as a statistical estimate of the value of something many years ago as compared to the current time.

Like if you purchased something in 1990 for $10, so what is the value of that thing in current time. Its the comparison of basically currency. That time, the value of $10 was very high as compared to today's time.

So, this is the difference that is measured by CPI.

This is based on inflation and this is the reason, there is a gradual change in living standard.

Answer:

One solution: 0x + 0.5y = 0

Step-by-step explanation:

9x + 4y = 36

6x + 2.5y = 24

2 * Eq. 1

18x + 8y = 72

-3 * Eq. 2

-18x - 7.5y = -72

Add the multiples of the equations.

0x + 0.5y = 0

Answer: One solution: 0x + 0.5y = 0

110 freshmen participated in sports or clubs or both. 55 are involved in sports and 68 are involved in clubs. How many students

Varvara68 [4.7K]

Answer: 42

Step-by-step explanation:

Let A represents the number of freshmen participated in sports and B represents the number of freshmen participated in clubs.

Then , we have given that

$n(A)=55\\\\n(B)=68\\\\n(A\cup B)=110$

Using formula

$n(A\cup B)=n(A)+n(B)-n(A\cap B)$

We have,

$110=55+68-n(A\cap B)\\\\\Rightarrow\ n(A\cap B)=123-110=13$

Now, the number of students are involved in just sports is given by :-

$n(A)-n(A\cap B)=55-13=42$

Hence, 42 students are involved in just sports.

What transformation maps quadrilateral EFGH to quadrilateral QRSP?

sashaice [31]

The markings indicate the figures are congruent. The orientation of both figures is clockwise, so no reflection is involved. The direction of QR appears to be 90° counterclockwise from the direction of EF, It appears as though the center of rotation is somewhere in the triangle EGS.

The transformation appears to be a 90° CCW rotation.
