UNO [17]

Customer price index is the price index which measures the weight average of price of basket of customers goods or services. The reasonable estimate of the current customer price index is 195. The option B is the correct option.

Given information-

The data table for the given problem is attached below.

<h3>Customer price index</h3>

Customer price index is the price index which measures the weight average of price of basket of customers goods or services. It can be given as,

CPI_t=\dfrac{C_t}{C_0} \times 100

Here C_t is the cost of market basket in current period and C_0 is the cost of market basket in the base period.

Cost of market basket in current period is.

C_t=126.85+29.95+2.25+44.25\\C_t=203.3

Cost of market basket in 1983 is,

C_0=67.45+15.25+1.15+22.85\\C_0=106.7

Put the value in the customer price index formula,

CPI_t=\dfrac{203.3}{106.7} \times 100\\CPI_t=190.5

Thus the value of current CPI is 190.5 which is near about the 195.

Hence the reasonable estimate of the current customer price index is 195. The option B is the correct option.

The area of a rectangle is the product of its length and width. Both length and width are whole numbers. A rectangular poster ha
Alona [7]

Answer:

17 inches.

Step-by-step explanation:

If the area of a rectangle is the product of its length and width, then;

Area of a rectangle = Length × Width

Given that the width of the poster is greater than 10 inches and is prime, this means and W>10

Area of the rectangle = 204in²

On substituting the values in the formula;

A = LW

204 = LW

Since W is greater than 10 and is prime, it can be between the prime numbers 11, 13 and 17. Note that L must be a whole number as well for any number to be the right answer we seek.

Let's test each values of the prime width that will give a length that is a whole number.

If W = 11

204 = 11×L

L = 204/11

L = 18.54

Since the length didn't give us a whole number, this means our width is not 11.

If W = 13

204 = L × 13

L = 204/13

L = 15.69

Also, we can see that the length is not also a whole number for the value of 13 as the prime width.

If W = 17

204 = L × 17

L = 204/17

L = 12

It can be seen that the length of the rectangle gave us a whole number when we used the prime width of 17, hence the width of the poster that is greater than 10 inches and is prime that makes both length and width to be a whole number is 17 inches.

50 POINTS+BRAINLIEST!!!!
Ilya [14]

Answer: So, we know that the internal angles of a triangle add up to 180 degrees, yes?  

60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.

Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!

Brainliest please if I am correct!  and hope it helped.

What is the common ratio and explicit formula for -2,6,-18,54?
Snezhnost [94]

Answer:

The explicit formula for a given geometric sequence is of the form

a_{4} =\frac{1}{(a_{1})^4}

Step-by-step explanation:

Given sequence is {\{-2,6,-18,54}\}

Let a_{1}=-2,a_{2}=6,a_{3}=-18,a_{4}=54

To find the common ratio r:

r=\frac{a_{2}}{a_{1}}

=\frac{6}{-2}

=-3

Therefore r=-3

r=\frac{a_{3}}{a_{2}}

=\frac{-18}{6}

=-3

Therefore r=-3

Therefore common ratio is -3

Therefore given sequence is geometric sequence.

The explicit formula for a geometric sequence is a_{n}=a_{1}^{r-1}, where common ratio is r.

From given sequence we are having  r=-3

Therefore the explicit formula for a given geometric sequence is of the form a_{4} =a_{1}^{-3-1}

a_{4} =a_{1}^{-4}

a_{4} =\frac{1}{(a_{1})^4}
