ANSWER

x = 22 \: units

EXPLANATION

The length of the two chords in the diagram are the same because equal chords are equal distance from the center.

We can see that the two chords are all 12 units from the center.

The line from the center meeting the chords at right angles bisects these chords.

Therefore

x = 2 \times 11

x = 22 \: units

malfutka [58]
Well you need to know that a yard is 36 inches. Therefore, you need to multiply 75 by 36 and you will get the amount of inches total which is 2700. Then turn that into feet by dividing it by 12. That gives you 225. Hope I helped!

lions [1.4K]

Answer:

Step-by-step explanation:

The sample proportion \hat p = \dfrac{50}{200}

\hat p = 0.25

The null hypothesis and the alternative hypothesis:

H_o: p = 0.20  \\ \\  H_1 : p > 0.20

Thus; the test statistics is:

Z = \dfrac{\hat p - p_o}{\dfrac{p_o(1-p_o)}{n} }

Z = \dfrac{0.25 -0.20}{\sqrt{\dfrac{0.20(1-0.20)}{200} }}

Z = \dfrac{0.05}{\sqrt{\dfrac{0.16}{200} }}

Z = \dfrac{0.05}{\sqrt{0.0008 }}

Z = 1.768

P-value = 2 × P(Z< - 1.768)

From the z tables

P-value = 2 × 0.03853

P-value = 0.07706

Thus, the p-value is 0.05 < P-value < 0.10
