Answer: kindly check explanation
Step-by-step explanation:
Given that number of dolphins = 800 with different length and ages
Median length = 5.8 feets
The median may be explained to be a measure of center which gives the information as regards around the middle or midpoint of a dataset. According to the information above, the median length if the 800 dolphins is 5.8 feets, this means the 50th percentile value is 5.8 feets and hence, Half of the dolphins sampled have a length which is greater than 5.8 feets and the other half has a length which is less than 5.8 feets.
The probability that the market will go up and interest rate will go down during the period in question is 0.03.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that the market will go up and interest rate will go down = 0.08 X 0.40 = 0.03

The answer to this is y= 5.
<span>We need to divide 72 rolls into 2 groups so that their ratio is 3:5. First, we can see that the ratio of 3:5 tells us there is 8 separate groups of rolls. Now its easy, since we have 72 rolls and we need to divide them into 8 equal groups: 72/8=9. So each group has 9 rolls. Now we separate them into groups with the ratio 3:5, so: 3*9:5*9 and that is: 27 rolls and 45 rolls. </span>
