Answer:

Mean = 62

Step-by-step explanation:

X = mean ± sd

82 = mean + 2(s.d) - - (1)

32 = mean - 3sd ___(2)

82 = mean + 2sd

82 - 32= 2sd + 3sd

50 = 5sd

sd = 50/5

sd = 10

From (2):

32 = mean - 3sd

32 = mean - 3(10)

32 = mean - 30

32 + 30 = mean

62 = mean

Con has two credit cardsU and V. card U has a balance of 414.55 card V has a balance of $751.81 the minimum monthly payment on c
Stells [14]

Answer:

$11.54

Step-by-step explanation:

The computation of the greater amount on card V than card U by considering the minimum payment is shown below:

But before that first we have to compute it separately and then take a difference to reach a solution

On Credit card U

= Balance × given percentage

= $414.55 × 2.82%

= $11.69

On Credit card V

= Balance × given percentage

= $751.81 × 3.09%

= $23.23

So, the difference in amount is

= $23.23 - $11.69

= $11.54

(08.03) Consider the following pair of equations:
Luba_88 [7]

Substitution method is used to solve the linear system of equations for one or more variables.

Consider the first equation y = 3x + 3 -----(1)

In equation (1) plug in y=x-1, we get

x -1 = 3x + 3

Add -3x on both side , we get

x-3x -1 = 3x-3x +3

-2x-1=0 + 3

Now add +1 on both sides, we get

-2x-1+1= 3+1

-2x + 0 =4

Now divide both side by -2

-2x/-2= 4/-2

X= -2

Now put x=-2 in the the second equation,

y=x-1

y=(-2)-1

y=-3

Solution(-2,-3)

Debbie cut a cord into sixths . She used five of the to make necklaces . She used equal lengths of the remaining cord for each o
Brut [27]
So she used \frac{5}{6} of the cord to make necklaces.
1- \frac{5}{6} = \frac{1}{6}

She splits the \frac{1}{6} length into 4 equal lengths.
To divide a fraction by a fraction, you multiply it by its reciprocal.
\frac{1}{6} ( \frac{1}{4})
=\frac{1}{24}

She used \frac{1}{24} of the original chord to make each bracelet.
