Answer:
37
Step-by-step explanation:
Here, we have two different samples, hence, to obtain the confidence interval, we use the relation for the confidence interval for two sample means ;
(x1 - x2) ± Margin of error
Where, (x1 - x2) = point estimate of the sample mean, this is the difference in mean of the two samples.
From the question ;
x1 = 1150 ; x2 = 1113
Hence, the point estimate is : (1150 - 1113) = 37
Give me points first!! 9ft is the answer
Question 1)
Let "y" denotes the number of yards and "m" denotes the number of meters. According to the give statement, measurement in yards can be changed to measurement in meters by multiplying the measure in yards by 0.9144.
So,
Measure in Meter = 0.9144 x Measure in Yards
m = 0.9144y
Question 2)
We are to convert 7200 yards into meters. Using the values in above equation we can write:
m = 0.9144 x 7200
m = 6583.68 meters
This means 7200 yards are equivalent to 6583.68 meters..
Question 3)
We are to convert 2500 meters to yards.
Using the value in above equation, we get:
2500=0.9144y
⇒
y = 2500/0.9144
y = 2734.03 yards
So this means 2500 meters are equivalent to 2734.03 yards.

Step-by-step explanation:
Let ratio be x
$72=5x+4x
$72=9x
X=$72/9=$8
Required share=5×$8=$40
And 4×$8=$32
