Aliun [14]

Answer:

The correct option is C) Both of the above.

Step-by-step explanation:

Consider the provided statement.

First understand the meaning of Confidence level.

Confidence level refers to the percentage of likelihood, or assurance, that when you draw a random sample several times, the confidence interval will contain the true population variable.

99% confidence means We are 99% sure that most of these confidence intervals contain the true parameter of the population.

Therefore, both the statement are correct.

Hence, the correct option is C) Both of the above.

A=63°
bekas [8.4K]

Answer:

B. 7.35 inches

Step-by-step explanation:

In the triangle:

  • A=63°
  • c = 7.75 inch
  • B = 47°

Now we know that:

\angle A+\angle B+\angle C=180^\circ$ (Sum of angles in a \triangle)\\63^\circ+47^\circ+\angle C=180^\circ\\\angle C=180^\circ-(63^\circ+47^\circ)\\\angle C=70^\circ

Using the Law of Sines

\dfrac{a}{\sin A} =\dfrac{c}{\sin C}\\\\\dfrac{a}{\sin 63^\circ} =\dfrac{7.75}{\sin 70^\circ} \\\\a=\dfrac{7.75}{\sin 70^\circ} \times \sin 63^\circ\\\\a=7.35$ inches (to the nearest hundredth of an inch)
