shoppers with store credit
cards: 37 through 80
Answer: a) and b)
Step-by-step explanation: Lets find the percentages for each option.
a). with 1-11 without 12-20
Here there are 20 shopers. From 1 to 11, there are 11 shoppers. From 12 to 20, there are 9 shoppers. 11 of 20 have credit cards, and 11/20 = 0.55. So this option is correct
b). with 1-33 without 34-60
Here there are 60 shoppers. 1 to 33 there are 33 shoppers with store credit cards. 33/60 = 0.55. So this is also a simulation which represents this situation.
c). with 1-24 without 25-40
Here there are 40 shoppers. 1 to 24, so there are 24 shoppers with the store credit card. 24/40 = 0.6. So this is not a correct option.
d). with 1-21 without 22-40
Here there are 40 shoppers, of which 21 have the credit card. 21/40 = 0.525, so this is not one of the options
e). with 1-18 without 19-40
Here there are 40 shoppers, of which 18 have the credit card. 18/40 = 0.45, so this is not one of the options.
f). with 1-36 without 37-80
Here there are 80 shoppers, of which 36 have the credit card. 36/80 = 0.45,
so this is not one of the options.

Answer:
True.
Step-by-step explanation:
A system of a mathematical expression such as a matrix is said to be in echelon form when it has many variables.
There are two (2) forms of echelon matrices and these includes;
I. Reduced row echelon form (RREF)
II. Row echelon form (REF)
Hence, a system in echelon form can have more variables than equations.

Use the scale factor from Part I and a proportion to find the length of RT. Show your work.
Similar triangles are those triangles whose corresponding sides are in the same ratio. The length of the sides ST and RT are 5 units and 3 units, respectively.
What are similar triangles?Similar triangles are those triangles whose corresponding sides are in the same ratio. And the corresponding angles measure the same. It is denoted by ‘~’ symbol.
Given that the two triangles are similar because the two have the same ratio. Therefore, the ratio of the corresponding sides in the triangle can be written as,
Ratio = AB/RS = BC/ST = AC/RT
Ratio = 18/6 = 15/ST = 9/RT
Now, using the ratio the length of the sides can be written as,
18/6 = 15/ST
ST = (15 × 6)/18
ST = 5 units
18/6 = 9/RT
RT = (9 × 6)/18
RT = 3 units
Hence, the length of the sides ST and RT are 5 units and 3 units, respectively.

A multiplier of 1.641 corresponds to a percentage increase or decrease of what percent?
Answer:
A multiplier of 1.641 corresponds to a percentage increase or decrease of 64.1%.
Step-by-step explanation:
To determine a percentage increase or decrease of a certain number, a calculation consisting of the multiplication of said number by 1 plus the decimals corresponding to the percentage to be increased must be performed. Thus, for example, if you want to increase a number by 50%, you must multiply that number by 1.50. Therefore, if you multiply a number by 1,641, this implies that you are wanting to increase or decrease the initial number by 64.1%.
Ann Nguyen would like an installment loan for $5,750. Her bank will loan her the
money at 18% for 18 months. Her insurance company will loan her the money at
18% for 24 months. How much money will she save by choosing the smarter loan?
9514 1404 393
Answer:
$281.40
Step-by-step explanation:
A financial calculator tells you the payment for the 18-month loan is $361.46, so her total payback amount is $6506.28.
Similarly, the payment for the 24-month loan is $282.82, and the total amount repaid is 6787.68.
The shorter-term loan costs less by ...
$6787.68 -6506.28 = $281.40
Ann can save $281.40 by choosing the shorter-term loan.
