In this problem,, we are told that Mr Nelson needs 5 1/2 yards of fabric to make two dresses. the problem then asks us to find out how much fabric it will take to make only one of the dresses. this means that in order to find out how much fabric is needed to make only one of the two dresses,, we need to divide the total amount of fabric by two. the equation will look like the following:
5 1/2 ÷ 2
the first step to solving this is to convert the mixed number to an improper fraction
11/2 ÷ 2
now,, you can turn the 2 into a fraction and changed the sign because dividing is equivalent to multiplying with the reciprocal value.
11/2 × 1/2
you must then multiply the fractions
11/4
finally,, you need to simplify the fraction to find the answer
2 3/4 yards
since you cannot simplify any further,, the correct answer to your question is A, 2 3/4 yards.
let me know if you have any further questions

A mechanic sells a brand of automobile tire that has a life expectancy that is normally​ distributed, with a mean life of 34 , 0
Leya [2.2K]

Answer:

He should word his statement as "Free replacement for tires that wear before 30875 miles."

Step-by-step explanation:

If he is willing to replace 10% of tires he should find the life of tires that gives an area of 10% in the normal distribution graph.

Now for 10% of area standard normal deviate Z can be obtained from normal distribution table

Using normal distribution table for 10% area we have Z = -1.28

Thus we have Z=\frac{X-\overline{X}}{\sigma }\\\\\therefore X=\sigma Z+\overline{X}

Applying given values we get

X=-1.28\times 2500+34000\\\\X=30875miles

How do I rewrite In 7=y as an exponential equation? I kind of forgot how to do these
Marina CMI [18]

Answer:

e^y=7

Step-by-step explanation:

ln(7)=y

e^{ln(7)}=e^y

7=e^y

Raising e to both sides cancels out the natural logarithm on the left side and we have our exponential form. This works with other bases (recall that the natural logarithm, ln, has base e)
