The probability is 0.2 that a person shopping at a certain store will spend less than $20. For groups of size 17, find the mean

Mila [183]

Answer:

<em>The correct option is : C. 3.4</em>

Step-by-step explanation:

The probability that a person shopping at a certain store will spend less than $20 is 0.2

That means, here $p= 0.2$

Given that, the sample size $(n)= 17$

So, the Mean $=n*p= 17*0.2=3.4$

Thus, the mean number who spend less than $20 will be 3.4

Answer:

$sin \theta = \frac{\sqrt {19}}{10}$

Step-by-step explanation:

$( \sin \theta) ^{2} + ( \cos \theta) ^{2} = 1 \\ \\ \therefore \:( \sin \theta) ^{2} + { \bigg( \frac{{9} }{10} \bigg)}^{2}= 1 \\ \\( \sin \theta) ^{2} + \frac{81}{100}= 1 \\ \\ ( \sin \theta) ^{2} = 1 - \frac{81}{100} \\ \\ ( \sin \theta) ^{2} = \frac{100 - 81}{100} \\ \\ ( \sin \theta) ^{2} = \frac{19}{100} \\ \\ \sin \theta = \sqrt{\frac{19}{100} } \\ \\ \sin \theta = \frac{\sqrt {19}}{10}$
