Answer:

c) 1 2 4 8

Step-by-step explanation:

<u>Explanation </u>:-

<u><em>Geometric sequence</em></u>

The sequence is of the form a , a r , a r² , a r³ ,.......

'a' is the first term

'r' is the common ratio

1 , 1(2) , 1( 2)² , 1( 2 )³ ......  is a geometric sequence

here a = 1

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

                        r =  \frac{4}{2} = 2

                       r =  \frac{8}{4} = 2

<em>The sequence 1 2 4 8 is a geometric sequence</em>

              Upper ≠ 1 so statement is false

<u>Step-by-step explanation:</u>

The Lower quartile (Q1) is the left side of the box.<em> I estimate it to be 1.</em>

The Median (Q2) is the line dividing the box.<em> I estimate it to be 2.</em>

The Upper quartile (Q3) is the right side of the box.<em> I estimate it to be 4.</em>

Leslie has a voucher worth $5 coupon from Wal-Mart.She visits the store and purchases a wallet that amounted to double the price
jasenka [17]

Answer:

The Cost of wallet was $26.30.

Step-by-step explanation:

Given:

Total billed after redeeming voucher = $34.45

Voucher worth = $5

We need to find the cost of Wallet.

Solution:

Let the amount paid for groceries be 'x'.

Now Given:

She purchases a wallet that amounted to double the price she paid for the groceries she bought.

Cost of wallet = 2x

Now to find the cost of wallet we will consider the amount before redeeming the voucher.

Hence Total bill before redeeming the voucher = \$34.45+\$5=\$39.45

Now We can say that;

Total bill is equal to sum of Cost of wallet and Cost of groceries.

framing in equation form we get;

x+2x=39.45\\\\3x=39.45

Dividing both side by 3 we get;

\frac{3x}{3}=\frac{39.45}{3}\\\\x=\$13.15

Cost paid for groceries = $13.15

Cost paid for wallet = 2x=2\times 13.15 =\$26.30

Hence the Cost of wallet was $26.30.
