Answer:

The amount in the account in the beginning of the 6th year is $6375 .

Step-by-step explanation:

Formula

$Simple\ interest = \frac{Principle\times Rate\ times Time}{100}$

As given

You invest $5000 in an account at 5.5% per year simple interest.

Principle = $ 5000

Rate = 5.5 %

Time = 5 years

(As calculate amount in the account for beginning of 6th year.)

Putting all the values in the formula

$Simple\ interest = \frac{5000\times 5.5\times 5}{100}$

$Simple\ interest = 50\times 5.5\times 5$

Simple interest = $ 1375

Amount = Principle + Simple interest

Putting values in the above formula

Amount = $5000 + $1375

Amount = $ 6375

kenny6666 [7]

we know that

Normal distribution:

The normal distribution is a very common continuous probability distribution

A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean

now, we will check each options

option-A:

we know that number of coupons will always be counted

so, it is discrete in nature

so, this is not normal distribution

option-B:

we know that

the weights of the pumpkins that are delivered to a supermarket can be any values

so, this will be continuous in nature

so, this is normal distribution

option-C:

the number of raisins in each 8-oz box of raisins at a supermarket

number will always be counted

so, this is discrete in nature

so, this is not normal distribution

option-D:

the amount of time customers spend waiting in the checkout line at a supermarket

time can be decimal or number

so, this is continuous in nature

so, this is normal distribution

A typical song downloaded from the internet is 4 megabytes in size. Lindy has satellite internet, and her computer downloads mus

nasty-shy [4]

So the first thing you do is you divide 1024 by 256. you will come out with the answer of 4. it takes 4 seconds to download 1 megabyte. but, it takes 4 megabytes, so you need to multiply 4 by 4. you will get 16. it takes 16 seconds to download 1 song.

to figure out how many songs Lindy can download in 2 hours, you multiply 60 by 60. you will get an answer of 3600. there are 3,600 seconds in an hour. now to find out how many are in 2 hours you multiply 3,600 by 2. you will get a sum of 7,200

now to figure out how many songs Lindy can download in 2 hours, you divide 7,200 by 16. you will come out with a quotient of 450.

Lindy can download a total of 450 songs in the space of 2 hours.
