They're usually 365 days in each year every 4th year is call a leap year and has one extra day in February how many days are the
Mariana [72]

Answer:

Total number of days in 8 years is 2,922 days.

Step-by-step explanation:

Number of days in a Normal year  = 365 days

Number of days in a  leap year  =  366 days

Also, Leap year comes exactly ONE TIME in every FOUR YEARS.

⇒ In every consecutive 4 years, 1 year is a leap year.

⇒ So, number of leap years in 8 years  =   2

Now, 8 Years  = 6 Normal years +  2 leap Years

<u>Number of days in 6 normal years</u>

= 6 x ( Number of days in a regular year)

= 6 x (365 days)  = 2,190 days

<u>Number of days in 2 leap years</u>

= 2 x ( Number of days in a leap year)

= 2 x (366 days)  = 732 days

So, Total number of days in 8 years

= Number of days in 6 regular years  + Number of days in 2 leap years

= 2,190 days  +  732 days

= 2,922 days

Hence, total number of days in 8 years is 2,922 days.

timofeeve [1]

Answer:

\frac{37}{389}

Step-by-step explanation:

Given that a  medical study investigated the effect of calcium and vitamin supplements on the risk of older Americans for broken bones. A total of 389 older Americans who lived at home and were in good health were studied over a three-year period. While all of the 389 people took in at least 700 milligrams of calcium and 200 units of vitamin D through their normal diet, 187 of them were given additional supplements containing 500 milligrams of calcium citrate and 70 units of vitamin D daily. Of the 187 who took additional supplements, 11 of them suffered broken bones over the three-year period. Of the 202 older Americans who did not take the additional supplement, 26 of them suffered broken bones over the study period.

                     Group I           Group II           Total

n                      187                  202                389

favour x             11                    26                  37

The fraction of older Americans who were included in the study suffered broken bones during the three-year period

=Total x/total n

= \frac{37}{389}
