t+12÷t-8=0
3 : 1, or 3 to 1, thus 3 times as many.
Answer:
It is on the x - axis
Step-by-step explanation:
Point (2, 0) lie on the x axis
Answer:
It is on the X axis
Step-by-step explanation:
The horizontal line is the x axis and the x coordinate is always given first (x, y) or in this case (2, 0)
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.

Answer: 120 lb of potatoes.
Step-by-step explanation:
Let the pounds of potatoes sold by farmer Bill = X lb
Fractional part sold to the first person = 1/4
Therefore 1/4 of X = 1/4 x X
= X/4 lb of potatoes.
No of potatoes left for sale = X - X/4
= ( 4x - x )/4
= 3x/4 lb.
Fractional part sold to the second person out of the reminder = 4/9
Therefore 4/9 of 3x/4 = 4/9 x 3x/4
= x/3 lb of potatoes.
Amount of potatoes left for sale = 3x/4 - x/3
Resolve into fraction , we have = (9x - 4x)/12, because 12 is the LCM.
= 5x/12
Third buyer bought 4/5 of the left over = 4/5 of 5x/12
= x/3 lb of potatoes.
Amount of potatoes left = 5x/12 - x/3
Resolve in to fraction again taking 12 as the LCM = ( 5x - 4x )/12
= x/12 lb of potatoes .
Therefore, the left over was 10 lb .
To determine the value of x now which correspond to the amount of potatoes sold by Farmer Bill, we shall the equate the left to x/12 = 10
we now cross multiply to get the value of x x = 120 lb.
therefore the pound of potatoes sold by farmer Bill = 120 lb.
