There's a theorem for this: the angle made by two intersecting secants of a circle has a measure equal to half the difference of the arcs the secants intercept. In this case,
<em>x</em> = (130° - 30°) / 2 = 50°
For a clinical trial (study) on the proportion of people who own cats, the appropriate null and alternative hypotheses would be given by:
<h3>What is a null hypothesis?</h3>
A null hypothesis (H₀) can be defined the opposite of an alternate hypothesis (H₁) and it asserts that two (2) possibilities are the same.
For a clinical trial (study) on the proportion of people who own cats, the appropriate null and alternative hypotheses would be given by:
In conclusion, we can infer and logically deduce that this test would be right-tailed.

7 because the circumference is 22
If u can find it i can’t sorry lol
The roots of
f(x) = x² - 48
are found by solving
x² - 48 = 0
x² = 48 . . . . . . add 48
x = ±√48 . . . . take the square root
The roots of f(x) are -4√3 and +4√3.
