Gekata [30.6K]

Answer:

$46.746

Step-by-step explanation:

Allen is buying a video that originally cost = $ 49

Discount coupon = 10%

Sales tax= 6%

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{100-10}{100}×\frac{100+6}{100}

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{90}{100}×\frac{106}{100}

Price of video after discount coupon and sales tax= $ 49 × 0.9× 1.06

price of video after discount coupon and sales tax=  $46.746

Hence, the correct answer is $46.746

zavuch27 [327]

Answer:

50.72 us fl oz

Step-by-step explanation:

Given:

500 ml of ingredient to be mixed with 1000 ml of another ingredient.

\therefore \textrm{Total solution contains} = 1500ml

Now we need to convert ml into Ounces.

Formula:

\texttrm{us fl oz} = ml \times 0.033814= 1500 \times0.033814 = 50.72 oz

\therefore \textrm{Total solution contains} = 50.72 ounces

Suppose that the waiting time for a license plate renewal at a local office of a state motorvehicle department has been found to
zysi [14]

The probability that a randomly selected individual will have a waiting time between 16 and 44 minutes is 93.72%.

Given mean of 30 minutes and standard deviation of 7.5 minutes.

In a set with mean d and standard deviation d. , the z score is given as:

Z=(X-d)/s.

where d is sample mean and s is standard deviation.

We have to calculate z score and then p value from normal distribution table.

We have been given d=30, s=7.5

p value of Z when X=44 subtracted by the p value of Z when X=16.

When X=44,

Z=(44-30)/7.5

=14/7.5

=1.87

P value=0.9686

When X=16

Z=(16-30)/7.5

=-1.87

P Value=0.0314.

Required probability is =0.9686-0.0314

=0.9372

=93.72%

Hence the probability that a randomly selected individual will have a waiting time between 16 and 44 minutes is 93.72%.

A box contains 5 blue, 4 red, and 3 yellow marbles. Two marbles are randomly drawn and not replaced. What is the probability of
Nataly_w [17]

Answer:

the answer is 5/33

Step-by-step explanation:

Total marbles = 5 blue + 4 red + 3 yellow = 12

Two marbles are selected, first is blue which gives us :

5/12 --eq 1

Then red marble is selected ( note: one marble is already drawn and not replaced so we have a total of 11 marbles )

The probability of red gave us :

4/11 --eq 2

Now we multiply eq 1 and 2

5/12 x 4/11 = 5/33
