Suppose that you spin the double wheel pictured to the right. Assuming that the wheels are independent and each outcome is equal
Anna11 [10]

Answer:

0.125

Step-by-step explanation:

<u>Smaller Wheel</u>

Total Number of Equal Sectors = 8

The number of Red sectors =3

The probability of obtaining red on the smaller wheel =\dfrac38

<u>Larger Wheel</u>

Total Number of Equal Sectors = 12

The number of Red sectors =4

The probability of obtaining red on the larger wheel =\dfrac{4}{12}

Assuming that the wheels are independent and each outcome is equally​ likely, the probability that we get red on both wheels

=\dfrac38 \times \dfrac{4}{12}\\\\=\dfrac18\\\\=0.125

The probability is: 0.125

1.) you have a credit card with an initial balance of $3,168 and an interest rate of 12.75 % APR if you make no payments on the
polet [3.4K]

Answer:

1.) [B]

2.) [C]

(3.) [D]                            

Step-by-step explanation:

1.) Initial amount = $3168

Annual percentage rate = 12.75

per month percentage rate = 1.06%

Interest after 3 months =  P*R*T/100

                                      = 3168*1.06*3/100

                                      = 100.74 (aprox)

Balance after 3 months = 3168-100.74

                                        = $3270.06 (aprox) (B.)

2.) Gross pay = $2759

Total interest rate = 7.65%+12%+7% =  26.65%

interest amount= 26.65% *2759 =$728.24 (aprox)

Housing and fixing expenses= $728.54  (C.)

3.) 1 hour = $8.25

1 week= 35 hours

3 weeks = 35*3 hours = 105 hours

Total income= 105 hours = $8.25*105= $866.25

Total interest to be deducted = 7.65+13+9 = 29.65 %

Income after deducting interest =  $866.25-256.843 = $609.407

(D.)

3/8(2x-8/3x)=21 solve the equation for x​
mart [117]

Answer:

\boxed{\bold{x=-84}}

Explanation:

Multiply Both Sides By 8:

= \bold{8\cdot \frac{3}{8}\left(2x-\frac{8}{3}x\right)=21\cdot \:8}

Simplify:

= \bold{-2x=168}

Divide Both Sides By -2:

= \bold{\frac{-2x}{-2}=\frac{168}{-2}}

Simplify:

= \bold{x=-84}

//Mordancy //.
