Answer:
The way I was taught to do it is to change value into a total fraction, then multiple the numerators together, multiply the denominators together, and finally reduce as far as possible.
7/9 x 5 2/5 = 7/9 x 27/5 = 189/45 = 4 9/45 = 4 1/5
1 3/4 x 4 1/6 = 7/4 x 25/6 = 175/24 = 7 7/24
Answer:
6
Step-by-step explanation:
The constant of variation is the slope
k = (y2-y1)/(x2-x1)
= (30-18)/(5-3)
=12/2
= 6
So,
We can notice that the graph of g, is translated 2 units to the left and 4 units up. We can express these changes with the following equation:
Answer:
x = 1
Step-by-step explanation:
Given
3(x - 2) + 2 = 5(x - 3) + 9 ← distribute and simplify both sides
3x - 6 + 2 = 5x - 15 + 9
3x - 4 = 5x - 6 ( subtract 5x from both sides )
- 2x - 4 = - 6 ( add 4 to both sides )
- 2x = - 2 ( divide both sides by - 2 )
x = 1
Answer:
The explanatory variable is, in this case, the gender (men or women) of the person. The study wants to see if gender <em>explains </em>difference on the satisfaction about physical atractiveness.
The response variable will be the proportion that each gender has about this satisfaction. This is the result for which the differences will be tested.
Step-by-step explanation:
The study can be conducted asking to a sample of men and women if they feel satisfied with their physical atractiveness, in a way that the only possible responses are Yes or No.
This allows to get a sample proportion for men and women. In this way, we can later test the hypothesis on the difference between proportions.
With this information we can state the hypothesis and calculate the statistic and the P-value to get some conclusions.
The explanatory variable is, in this case, the gender (men or women) of the person. The study wants to see if gender <em>explains </em>difference on the satisfaction about physical atractiveness.
The response variable will be the proportion that each gender has about this satisfaction. This is the result for which the differences will be tested.
