2/3 of a foot is 8 inches
6 feet is 72 inches
72/8 is 9
the answer is 9 pieces of yarn
Bus company wants to use data to show how long a bus takes to complete the route:
The data set of the time taken to complete the route is given as follows:
31 31 31 33 31 32 32 60 31 32 33
Median: Median is the mid value of the data set when the data is arranged in the order from lowest to greatest. Mid value can help us create a bus schedule. Here in our case mean of the data set is 34.17 and there is another element in the data set that is 60 which is way beyond the average value.
Mean: Mean or the average is obtained by summing up all the values and dividing that by number of values in the data set. It can tell us how much time does the bus take on an average to complete the route and it can help up to create a bus schedule but in this case there are values which are way beyond the mean, therefore it is a little hard to consider mean to design a bus schedule.
Minimum: Minimum of a data set can not help us to create a bus schedule.
Range: Range is defined by the difference between the maximum and the minimum value of a data set, it can not help us to figure out how much time on an average does a bus take to complete its route.
So, in this case median can help us create a bus schedule.
Elaine, because she brought 0.75 pounds of potato salad while Jake brought 0.66 pounds of macaroni salad. The strategy you would use is you would divide 3 by 4 for the first part and 2 by 3 for the second part.
First you would have to set it up so that the fractions line up: 7/8
<u>- 5/8
</u>Since the denominators (8) are the same, you can just subtract the numerators. You then get 2/8, which can be simplified. If you divide both the numerator and the denominator by two, then your final answer becomes 1/4.
Answer:
15
Step-by-step explanation:
the height of the person is y = 6 and the distance from the ladder is also 6 = x. To find the angle formed by the ladder we use 
which in this case is
now we know that the person is 9 feet away from wall and 6 feet away from the ladder so the total x distance is 9+6 = 15 = x
to find y we use tan(45) = 
multiply both sides by x = 15 and simplify to get y = 15
