Answer: C. An inscribed angle

Step-by-step explanation:

Central angle is an angle that is subtended by an arc in a circle, it is also known as the arc's angular distance.

Interior angle is an angle between two sides inside a polygon or a shape.

Inscribed angle is an angle formed by two chords in a circle which have a common endpoint, and by the inscribed angle theorem, the measurement of inscribed angle is half the measure of the intercepted arc.

SOLUTION:

Case: Hypothesis testing

Step 1: Null and Alternative hypotheses

$\begin{gathered} H_0:\mu=P127.50 \\ H_1:\mu\leq P127.50 \end{gathered}$

Step 2: T-test analysis

$\begin{gathered} t=\frac{\hat{x}-\mu}{\frac{s}{\sqrt{n}}} \\ t=\frac{135-127.5}{\frac{75.25}{\sqrt{450}}} \\ t=2.144 \end{gathered}$

Step 3: t-test with the significance level

$\begin{gathered} t_{\alpha}=? \\ \alpha=0.05 \\ From\text{ }tables \\ t_{0.05}=1.654 \end{gathered}$

Step 4: Comparing

$t>t_{\alpha}$

So tail to reject the null hypothesis. There is enough evidence at a 0.05 level of significance to claim that the mean spent is greater than P127.50.

Final answer:

Yes, there is evidence sufficient to conclude that the mean amount spent is greater than P127.50 per month at a 0.05 level of significance.

A circle has a center at -4,-5 and a radius of sqrt6. what is the equation of the circle

scoundrel [369]

Answer:

Step-by-step explanation:

if (h,k) is the center and r be radius of circle.

Then eq. of circle is (x-h)^2+(y-k)^2=r^2

reqd. eq. of circle is (x+4)²+(y+5)²=(√6)²

or (x+4)²+(y+5)²=6
