Morgarella [4.7K]

Answer:

The mean is 0.32 and the standard deviation is 0.0122.

Step-by-step explanation:

Given that the Tampa Times polled 1,457 adults in the city to determine whether they put on their shirt before they put on their pants.

Of the respondents, 48% said they put their shirt on first.

32% of all adults actually put their shirt on first

i.e. sample proportion is 48% while population proportion is 32%

Hence sampling distribution follows a distribution with mean = population proportion p

Hence here mean = 0.32

Std deviation of sampling distribution = \sqrt{\frac{pq}{n} } =\sqrt{\frac{0.32(0.68)}{1457} } \\=0.0122

Hence option 3) The mean is 0.32 and the standard deviation is 0.0122.

is right

Leona purchased a $1,000 bond having a quoted price of 99.875. She had to pay a 5.5% brokerage fee (of the selling price). What
Ede4ka [16]

Answer:

None of these choices are correct.

Step-by-step explanation:

The quoted value of 99.875, means that this bond is sold at 99.875%  of the face value and not at a price of  $99.875.

Therefore, calculate price;

Price = 0.99875 * 1000

Price = $998.75

Since brokerage fees is 5.5% of the selling price, Leona will pay additional cost to the quoted price making the total cost to be more than $998.75;

Brokerage fees = (0.055*998.75) = $54.93

Total cost = $998.75 +$54.93

= $1053.68

Therefore, none of the choices is correct.

Maddie and her friends are making s'mores over the campfire. they have a bag of 48 marshmallows, 2 packs of graham crackers cont
VladimirAG [237]

The answer would be 16 S'mores and the limiting reactant would be the grahams.


(This is assuming that S'mores would need 2 grahams, 1 marshmallow and 1 chocolate piece.)


Limiting reactant would be the reactant that runs out first.


Let's take your problem into account and see what we have:

48 marshallows

32 grahams (2 x 16 per pack)

45 chocolate pieces (5 x 15 pieces per bar)


Since need 2 of the grahams per S'more then the maximum yield of the grahams is 16 S'mores.

The maximum yield of marshmallows is 48.

The maximum yield of chocolate is 45.


Since you cannot make S'mores without the grahams, then you can only make 16 S'mores before the grahams run out.
