Answer:
70.83% entrants will have distances between 150 and 160.
Step-by-step explanation:
This question is incomplete without an attachment; here is the attachment enclosed with the answer.
From the graph attached,
Number of entrants having distances between 150 and 160 feet = 8 + 9 = 17
Number of entrants between 140 and 200 feet = 8 + 9 + 4 + 2 + 1 = 24
Percent of entrants having distance between 150 and 160 feet =
=
= 70.83%
Therefore, 70.83% entrants will have distances between 150 and 160.
To find the percent of entrants with distances between 150 and 160 feet in the frequency polygon, calculate the area of the rectangle between the two values and divide it by the total area under the polygon. Multiply the result by 100 to get the percent.
To find the percent of entrants with distances between 150 and 160 feet, we need to look at the area under the frequency polygon between the two values. Since the frequency polygon represents the distribution of distances, we can estimate the percent by calculating the proportion of the area under the polygon between 150 and 160 feet. First, find the total area under the polygon by adding up the areas of all the rectangles formed by the frequency values and the width of each interval. Then, calculate the area of the rectangle between 150 and 160 feet by multiplying the frequency of that interval by its width. Finally, divide the area of the rectangle by the total area under the polygon and multiply by 100 to get the percent.

Step-by-step explanation:
b. 1/x^-1
=(1/x)^-1
=x
d. x^1/3 * x^1/3 * x^1/3
=x^1/3+1/3+1/3
=x^3/3
=x^1
=x....

Here are a couple of examples (a+b)c or (c+b)a or (a+c)b
Step-by-step explanation:
To “associate” means to connect or join with something. According to the associative property of multiplication, the product of three or more numbers remains the same regardless of how the numbers are grouped. Here's an example of how the product does not change irrespective of how the factors are grouped.
In 5 minutes 195 sit ups can be done.
For the given question.
If 78 sit-ups is done in 2 minutes.
this can be written as;
2 minutes -------> 78 sit ups.
For 1 minutes, divide both side by 2.
1 minutes -------> 39 sit ups.
For 5 minutes, multiply both sides by 5.
5 minutes -------> 195 sit ups.
Thus, in 5 minutes 195 sit ups can be done.
