9(1/3)¹⁰⁻¹
9(1/3)⁹

9/19683

Step-by-step explanation:
given a normal distribution with the given parameters the probability (= the % of the area of the distribution curve) for a number to be between 203 and 1803 is
0.9987
so, 99.87% of all numbers are expected to be in that range.
for 350,000 numbers that means
350,000×0.9987 = 349,545 numbers are expected to be between 203 and 1803.
Answer:
$56.70 all together
Step-by-step explanation:
$22.14 for the jeans
$34.56 for the jacket
$56.7 all together
Take your tax and move the decimal over to the left by 2 spaces
8. becomes .08
take .08 and multiply it by the price so
20.50 x .08= 1.64
and
32 x .08=2.56
the number you get is how much the tax is, $1.64 is 8% of $20.15
take that number and add it to your price
$1.64+$20.50= $22.14
