87 for t-shirts and 243 for sweatshirts, the total cost is 330
Given the expression,
We will have to rationalize the denominator first. To rationalize the denominator we have to multiply the numerator and denominator both by the square root part of the denominator.
If we have , we will get by multiplying them. And .
So here in the problem, we will get,
Now in the numerator we have . We can check 8x is common there. we will take out -8x from it, we will get,
And in the denominator we have . We can check 2 is common there. If we take out 2 from it we will get,
So we can write the expression as
is common to the numerator and denominator both, if we cancel it we will get,
We can divide -8 by the denominator, as -8 os divisible by 2. By dividing them we will get,
So we have got the required answer here.
The correct option is the last one.
Faye will have $1704.00 total money in her account.
She earned $504.00 interest for 7 years.
(She earned $144 for 2 years, divide in half $72 a year= $72×7=$504
Answer: A) .1587
Step-by-step explanation:
Given : The amount of soda a dispensing machine pours into a 12-ounce can of soda follows a normal distribution with a mean of 12.30 ounces and a standard deviation of 0.20 ounce.
i.e. and
Let x denotes the amount of soda in any can.
Every can that has more than 12.50 ounces of soda poured into it must go through a special cleaning process before it can be sold.
Then, the probability that a randomly selected can will need to go through the mentioned process = probability that a randomly selected can has more than 12.50 ounces of soda poured into it =
Hence, the required probability= A) 0.1587
