Answer:
c)
<em>The probability of a player weighing more than 238 </em>
<em>P( X > 238) = 0.0174</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given mean of the normally distribution = 195 pounds
Given standard deviation of the normally distribution
= 20 pounds.
<em>Let 'x' be the random variable of the normally distribution</em>
Let X = 238
<u><em>Step(ii):</em></u>-
<em>The probability of a player weighing more than 238</em>
<em>P( X > 238) = P( Z> 2.15)</em>
= 1 - P( Z < 2.15)
= 1 - ( 0.5 + A(2.15)
= 1 - 0.5 - A(2.15)
= 0.5 - 0.4821 ( from normal table)
= 0.0174
<em>The probability of a player weighing more than 238 </em>
<em>P( X > 238) = 0.0174</em>
There are four gray rectangles in the graph, showing 2 different probabilities. Add together the areas of the two rectangles located on the right side:
0.35+0.05 = 0.40 (answer)
Answer:
First, we need to calculate for x. Since,
MP = PN
Thus,
3x-4 = x+4
2x = 8
x = 4
Next, we calculate for MS
MS = 2x + 2 = 10
Since, MS = 2SQ
10 = 2SQ
Then,
SQ = 5 units
Therefore, the correct answer is B.
Answer:
$207.66
Step-by-step explanation:
Regular price = $349
clearance price = 30% of $349
= 0.03 * 349 = $104.7
therefore new price = $349 - $104.7 = $244.3 ( 70% of original price )
A customer using a 15% off coupon then the price would be
= ( 100% - 15%) ( 70% of $349 )
= 85% ( 70% of original price )
= 0.85 * $244.3 = $207.66 ( final cost of chair before sales tax )
sales tax is a tax been paid by the buyer on purchased item and the buyer purchasing the item after applying his coupon means that he would pay sales tax on the final price at which he bought the item and not the original price of the item.
