Answer:
x=9
Step-by-step explanation:
To solve for x, you can set up a proportion between the 2 triangles we see.
The small triangle can be written as
, and the large triangle can be written as
.
Set both proportions equal to each other.

Cross multiply and solve for x.

32x+272=560
32x=288
x=9
There are 1,61 kilometers in a mile or more correctly 1,60934 kilometers in a mile.
<span>But first, a short history.... Both kilometers and miles are units of measurement. They are used to measure distance. Miles are part of the imperial measurement system and kilometers are part of the metric measurement system. </span>
To calculate how many miles a person will run during a 10-kilometer race, you need to divide 10 kilometers by 1,61 miles (1,60934 rounded up to two digits).
Therefore your equation is as follows:
10÷1,61 or 10 000 meters ÷ 1 610 metres
1000 meters is equal to 1 kilometer.
The answer = 6, 21 miles.
Therefore, a person who runs 10 kilometers will run 6,21 miles
Answer: = ( 0.411, 0.409)
Therefore at 95% confidence interval (a,b) = (0.411, 0.409)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean gain x = 0.41
Standard deviation r = 0.016
Number of samples n = 1000
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
0.41+/-1.96(0.016/√1000)
0.41+/-1.96(0.000506)
0.41+/-0.00099
0.41+/-0.001
= ( 0.411, 0.409)
Therefore at 95% confidence interval (a,b) = (0.411, 0.409)
