Circle O is shown below. The diagram is not drawn to scale? If Angle r is 32, what is angle O?

liubo4ka [24]

We have to find the measure of angle O.
We already know that ∠R = 32°.
The measure of the inscribed angle ( here ∠ R ) is half the measure of the central angle ( here ∠ O ).
Therefore:
∠ O = 2 · 32° = 64°
Answer:
B ) 64°

Answer:

The value is $\sigma = 8.5$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 9.7$

The proportion is $P(X >x) = 0.2245$

The value considered is $x = 11.6$

Generally given that the speed measurement is normally distributed we have that

$P(X > 11.6) = P(\frac{ X - \mu }{ \sigma } > \frac{11.6 - 9.7}{ \sigma } ) = 0.2245$

Generally

$\frac{X - \mu}{ \sigma } = Z(The \ z -score \ of \ X )$

$P(X > 11.6) = P(Z> \frac{11.6 - 9.7}{ \sigma } ) = 0.2245$

Hence

$\frac{ 11.6 - 9.7}{ \sigma} = 0.2245$

$\sigma = 8.5$
