For the past 100 days hunter ran an average of 6.8 kilometers each day.(a)how many kilometers has he run in the last 100 days? (
myrzilka [38]

Answer:

(a) 680 km

(b) 680000 m

Step-by-step explanation:

(a) Distance run by hunter every day = 6.8 km

Total number of days under consideration = 100

So the total distance covered by the hunter = \[6.8 * 100\]&#10;

= 680 km

The hunter ran 680 km in the last 100 days.

(b) Converting this value to meters:

1 km = 1000 m

=> 680 km = 680 * 1000 m

= 680000 m

The equivalent distance run by the hunter when converted to meters is 680000 meters.

Determine whether or not the given procedure results in a binomial distribution. If not, identify which condition is not met. Sp
laila [671]

Answer:

Step-by-step explanation:

A binomial distribution as the name indicates two possible outcomes.

This procedure does not result in binomial distribution.

Conditions not met is that a binomial distribution only works when there are two choices available. And 7777 is not evenly divisible by 2.
