Answer: 33.33 minutes longer.
Step-by-step explanation :
We need to remember the following formula:
Where "t" is the time, "d" is the distance and "V" is the speed.
We know that she runs approximately 5.4 miles per hour, then:
Since she plans to run 9 miles on Tuesday, her run's time on Tuesday will be:
Making the conversion from hours to minutes, we get:
Since she plans to run 12 miles on Thursday, her run's time on that day will be:
Making the conversion from hours to minutes, we get:
Finally in order to find how many longer will her run be on Thursday compared to Tuesday, we need to make the following subtraction:
Answer:
y=-8
Step-by-step explanation:
First, rewrite the equation in slope-intercept form:
Now just look at the slope-intercept form and your y-intercept is -8, and your slope is .
If you don't know what slope-intercept form is it is y=mx+b where m is your slope and b is your y-intercept.
Hope this helps! :)
Answer:
Mixed probabilty
Step-by-step explanation:
What is the probability that the first and second ball chosen are both targets, that is, X1 = 1 X2 = 2?
For this we must study the simple probability of each, for example for the target in that event is 5/13. However for the second chosen but also white in the second event where there is already a total of 12 balls is 4/12.
Thus
In this way is generated for all probabilities
b) In the same way analogous to the past example we can perform all cases of combinations, therefore it would be so
Answer:
There are 52 cards in a deck. Four kings and 13 clubs. So the probability of choosing a king or a club is 17/52. The probability that it's both a king and a club is 1/52 because it's only one king that's a club. Hence for drawing a card from a deck, each outcome has probability 1/52. The probability of an event is the sum of the probabilities of the outcomes in the event, hence the probability of drawing a spade is 13/52 = 1/4, and the probability of drawing a king is 4/52 = 1/13.
