You have several options to add to your brand new car: leather seats, heated seats, sunroof, tinted windows, and back up camera.

scZoUnD [109]

Answer:

The number of different ways the car can be built is 31 different ways

Step-by-step explanation:

The given options are'

1), Leather seats, 2) Heated seats, 3) Sunroof, 4) Tinted windows, 5), back up camera

Therefore, the number of different ways the car can be built, n, is given as follows;

n = ₅C₁ + ₅C₂ + ₅C₃ + ₅C₄ + ₅C₅

n = 5 + 10 + 10 + 5 + 1 = 31 different ways

The number of different ways the car can be built = n = 31 different ways

1 + 1 + 2+2+2+2+3+3+3+3+3+3+3+3+3+4+4+4+4+4+4+4+4+5+5+5+5+5=94

94/29 = 3.3793103448276

Mean - 3.3793103448276

Median ( Find Middle Number)

3. A prescription for an ointment has 3.5 mL of liquid menthol in a total of 220 mL. Calculate the percentage (v/v) of liquid me

Marina CMI [18]

Answer:

The percentage (V/V) of liquid menthol in the ointment is 1.59%.

Step-by-step explanation:

Given : A prescription for an ointment has 3.5 mL of liquid menthol in a total of 220 mL.

To find : Calculate the percentage (V/V) of liquid menthol in the ointment ?

Solution :

Volume of liquid menthol is $V_m= 3.5\ mL$

Total volume of ointment is $V_t= 220\ mL$

The V/V percentage is given by,

$\frac{V}{V}\%=\frac{V_m}{V_t}\times 100$

$\frac{V}{V}\%=\frac{3.5}{220}\times 100$

$\frac{V}{V}\%=0.0159\times 100$

$\frac{V}{V}\%=1.59\%$

Therefore, the percentage (V/V) of liquid menthol in the ointment is 1.59%.
