You can add the whole numbers as is.

2 + 16 = 18

Add the fractions with the same denominator.

Find the common denominator between 5 and 9.

The common denominator should be 45.

Write both fractions with a denominator of 45.

3/5 → 27/45

4/9 → 20/45

Add the new fractions as is:

27/45 + 20/45 = 47/45

Write 47/45 as a mixed fraction.

47/45 → 1 2/45

Add both the whole number and the mixed fraction.

18 + 1 2/45 = 19 2/45

Solution: C) 19 2/45g

Weinstein, McDermott, and Roediger (2010) con- ducted an experiment to evaluate the effectiveness of different study strategies.
anastassius [24]

Answer:

a) The number of correct answers

b) Discrete

c) Ratio        

Step-by-step explanation:

We are given the following in the question:

Experiment:

Evaluate the effectiveness of different study strategies. All students were then given a test on the passage material and the researchers recorded the number of correct answers.

a) The dependent Variable

The number of correct answers given is the dependent variable because it depends on the number of times the passage is read.

b) Nature of dependent variable.

  • It is a discrete variable.
  • Since, the number of questions will always be expressed in whole numbers and cannot be expressed as decimals.
  • They are always counted and not measured.

c) Scale of measurement

  • Ratio is used to measure the dependent variable because true zero for the number of correct questions answered exist.
  • If the measure is zero that means truly no questions were answered correctly.

Gabrielle is x years old.
Felicia is 6 years older.....so Felicia is x + 6
the mom is twice as old as felicia...so the mom is 2(x + 6)
the aunt is x years older then mom....so the aunt (tanya) is 2(x + 6) + x

so Tanya/s age is :
2(x + 6) + x =
2x + 12 + x =
13x + 12 <===
