A large restaurant chain wanted to determine if its employees were taking sick days on some days of the week more than others. T
lidiya [134]

Answer:

0.2

Step-by-step explanation:

Given the data :

Day : Mon Tue Wed Thu Fri Sat Sun

# of sick days 22 11 16 17 21 28 25

The expected count of sick days taken on Saturday is obtained thus :

Expected count = (row total * column total) / overall total

Here, the table is just one way :

Hence, we use :

Observed value / total days

Hence,

Expected count on Saturday = sick days on Saturday / total sick days

Expected count on Saturday = 28 / (22+11+16+17+21+28+25)

Expected count on Saturday = 28 / 140

= 0.2

An airplane is flying 35,000 feet above sea level .the airplane starts to descend at a rate of 2,500 feet per minute .let m be t
marusya05 [52]

Answer:

35000 - 2500m

Step-by-step explanation:

Height of the airplane before it starts descending = 35,000 feet

Rate of descend = 2500 feet per minute

This means for every 1 minute the height of airplane is decreasing by 2500 feet. So, for every "m" minutes the height of airplane will decrease by 2500m feet.

Let h(m) denotes the height of the airplane after m minutes. The equation for h(m) can be set up as:

Height of airplane at m'th minute = Original Height - Distance descended in m minutes

So,

h(m) = 35000 - 2500m

This expression describes the height of airplane after any number of minutes(m).
