The time X it takes Hattan to drive to work on a randomly selected day follows a distribution that is approximately Normal with

mean 15 minutes and standard deviation 6.5 minutes. Once he parks his car in his reserved space, it takes 5 more minutes for him to walk to his office. Let T = the total time it takes Hattan to reach his office on a randomly selected day, so T = X + 5. Describe the shape, center, and variability of the probability distribution of T.

Dons signature coffee blend is 60% dark roast and 40% light roast. He has 10 kg of blend A, which is 80% dark roast and 20% ligh
astraxan [27]

Answer

Find out the how many kilograms of blend A will don need to use to make 10 kg of his signature blend .

To proof

As given

Dons signature coffee blend is 60% dark roast and 40% light roast.

He has 10 kg

60 % is written in the decimal form

= \frac{60}{100}

= 0.6

40 % is written in the decimal form

= \frac{40}{100}

= 0.4

Now 60% dark roast of  10 kg = 0.6 ×10

                                                 = 6 kg

Now 40% of  10 kg = 0.4 × 10

                               = 4 kg

As given

He has 10 kg of blend A, which is 80% dark roast and 20% light roast  i.e 80% of the 6kg is dark roast and 20% of the  4kg is light roast .

80% is written in the decimal form

= \frac{80}{100}

= 0.8

80% of the 6kg is dark roast = 0.8 × 6

                                                = 4.8 kg

20% is written in the decimal form

= \frac{20}{100}

= 0.2

20% of the 4kg is light roast = 0.2 × 4

                                               = .8kg

Total kilograms of blend A will don need to use to make 10 kg of his signature blend =  4.8 kg + .8 kg

                          = 5.6 kg

Hence proved

1,478 people went to the movies on Saturday, and 956 people went to the movies on
wlad13 [49]

The percent decrease in people going to the movies from Saturday to Sunday is 35.3%

Step-by-step explanation:

The percent decrease is given by the formula:

Percent\ decrease = \frac{Decrease}{Old\ Value}*100\\where \\Decrease = Old\ value -New\ value\\

Given

New Value = 956

Old Value = 1478

Decrease = 1478-956

= 522

Percent\ decrease= \frac{522}{1478}*100\\=0.353*100\\=35.3\%

The percent decrease in people going to the movies from Saturday to Sunday is 35.3%
