Answer:
y - x = 16
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<u>Step(i)</u>:-
Given data set A is 9,5,y,2,x
<em>Mean of the Data set A </em>
<em> = </em>
<em></em>
<em> = </em>
<em></em>
<em>Given data set B is 8, x, 4, 1, 3</em>
<em>Mean of the Data set B </em>
= 
<u><em>Step(ii):-</em></u>
<em>Mean of the Data set A = 2 X Mean of the Data set B </em>
<em> </em>
<em></em>
<em>On simplification , we get</em>
16 +x + y = 2( 16 +x)
16 + x + y = 32 + 2 x
16 + x + y - 32 - 2 x = 0
y - x -16 =0
y - x = 16
Answer:
Step-by-step explanation:
Given that taxi Fares are normally distributed with a mean fare of $22.27 and a standard deviation of $2.20.
For a random single taxi std deviation is 2.20
But for a sample of size 10, std deviation would be
This would be less than the 2.20
Because std devition is less for sample we get a big z score for the sample than the single.
As positive values of z increase we find that probability would decrease since normal curve is bell shaped.
So single taxi fare would have higher probability than sample.
B) Here >24.
By the same argument we have z value less for single taxi hence the probability for more than that would be less than that of sample size 10
2 x pi radians = 360 degrees, [remember this formula]
2 x 3.14 = 6.28 radians = 360 degrees
therefore 1 radian = 360 degree/ 6.28 or 57.32 degrees approx.
3.5 radians is therefore = 57.32 x 3.5 = 200.62
closest answer would be b ) 200.54 degrees
