Answer:
x = 3, JL = 17, MN = 13
Step-by-step explanation:
Given 2 intersecting chords in a circle , then
The product of the parts of one chord is equal to the product of the parts of the other chord, that is
14x = 7 × 6 = 42 ( divide both sides by 14 )
x = 3
Then
JL = x + 14 = 3 + 14 = 17
MN = 6 + 7 = 13
Answer:
30
Step-by-step explanation:
Subtract the 3 from both sides of the equation.
Divide both sides of the equation by 3
Raise both sides of the equation to the 5th power
Take the cube root of both sides of the equation
Subtract 2 on both sides of the equation
[67.9 %, 82.1 %] is the 95% confidence interval for the proportion of test-takers answering the question correctly. So we have [67.9 %, 82.1 %] In a random sample of 144 test-takers with 75% answered the question correctly. So the answer in this question is [67.9 %, 82.1 %].
