Given:
Consider the below figure attached with this question.
To find:
The solution to this linear system.
Solution:
From the below graph it is clear that both lines intersect each other at point (2,3).
Here,
x-coordinate = 2
y-coordinate = 3
Therefore, the solution to the given system is (2,3).
Hence, the required answer for first blank is 2 and for second blank is 3.
Answer: 0.030
Step-by-step explanation:
Given: The percent of the items produced by a machine are defective :
The percent of the items produced by machine which are not defective:
Sample size : n = 100
Now, the standard error of the proportion is given by :-

Hence, the the standard error of the distribution of the sample proportions=0.030
Answer:
The distance between the end of the ramp and the bottom of the platform is about 9.8 feet
Step-by-step explanation:
use the pythagorean theorem (a²+b²=c²) to solve
a and b are the legs, c is the hypotenuse
plug in given values:
2² + x² = 10²
solve for x:
x² + 4 = 100
x² = 96
x ≈ 9.80
