Allana used fraction 3 over 5 yard of fabric to make a scarf. can she make 2 of these scarves with fraction 1 and 7 over 10 yards of fabric, and why? no, because the quotient of fraction 1 and 7 over 10 ÷ fraction 3 over 5 is 1 and 1 over 50 no, because the quotient of fraction 3 over 5 ÷ fraction 1 and 7 over 10 is 1 and 1 over 50 yes, because the quotient of fraction 1 and 7 over 10 ÷ fraction 3 over 5 is 2 and 5 over 6 yes, because the quotient of fraction 3 over 5 ÷ fraction 1 and 7 over 10 is 2 and 5 over 6

The answer is actully the third one

Step-by-step explanation:

Divide 1 7/10 by 3/5 to see if the quotient is greater than 2.  If it's not, you can't get 2 scarves out of it.  If it is, then you can get 2 scarves out of it and have whatever the remainder is as left-over.  Before we divide, let's change that 1 7/10 into an improper fraction since it will be easier to work with.

1 7/10 = 17/10

Now we can divide:

The rule for dividing fractions is that you bring up the lower fraction and flip it to multiply, so that looks like this:

×

To simplify before we multiply, we can reduce between the 5 and the 10 and have smaller numbers to deal with:

×

The product there is

So the answer you want from your choices is

"Yes, because the quotient of Fraction 1 and 7 over 10 [division sign]Fraction 3 over 5 is 2 and 5 over 6", third choice

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
