3. Use the following table to answer questions (a – c).
sineoko [7]

Answer:

See below

Step-by-step explanation:

B) The correlation coefficient is r=0.75, which can be determined by plugging the data into a TI-84 calculator.

C) A correlation coefficient of r=0.75 indicates that the correlation between the independent and dependent variable (x and y in this case) is moderately strong with a positive correlation. The closer r is to 1, the stronger the positive correlation. The closer r is to -1, the stronger the negative correlation. If r is closer to 0, then there's no correlation.

Darlene has 59 pages to type. so far she gas type 23 pages. what fraction of the job is finished ​
coldgirl [10]

Answer:

\frac{23}{59}

Step-by-step explanation:

A fraction can be found be taking the current amount over the total amount:

\frac{current}{total}=\frac{23}{59}

Since Darlene has only typed 23 pages out of 59, her fraction is 23 over 59.  Fractions must always be in simplest form, which means that both the numerator and denominator can no longer be divided by the same factor.  Since the numbers 23 and 59 are both prime and have no other factors other than 1 and themselves, the fraction 23/59 is in simplest form.
