If you are evaluating the answer is -41
Answer:
Step-by-step explanation:
A). From the table of relative frequencies,
Let the relative frequency of women who prefer mineral water = x
Total of relative frequencies of women preferring purified water and mineral water = 0.59
Since, Total of relative frequencies of women who prefer purified water and mineral water = Relative frequency of women preferring purified water + Relative frequency of women preferring mineral water
0.59 = 0.14 + x
x = 0.59 - 0.14
x = 0.45
B). Relative frequency of men who prefer mineral water = 0.13
Let the frequency of men who prefer mineral water = x
Since, relative frequency =
0.13 =
x = 200 × 0.13
x = 26
Therefore, number of shoppers who are men and prefer mineral water = 26
5/7m=-55
1.) First of all they are multiplying so you do the opposite. In this case you divide 5/7 by both sides.
-55divided 5/7
Changes to
-55/1 x 7/5. See if you can cross cancel in this case you can. The -55 changes to a -11 and the 5 changes into a 1
Reminder: Remember when you divided by fractions you change the sign to a multiplication sign and then flip the next fraction over.
2.) After dividing you should get -77/1 or if you didn't cross cancel then you would get -385/5.
3.) If you get -385/5 then you would have to do 385 divided 5 and you would get -77.
4.) Checking your answer is 5/7•-77=-55.
5/7•-77 changes to 5/7•-77/1 and you can cross cancel it where the -77 changes to a -11 and 7 changes to a 1.
5.) You should get -55. If you didn't cross cancel then you would have gotten -385/77
6.) If got -385/77 then you would do -385 divided by 77. Your then should get -55.
7.) Look to see if the answer you got when you checked matches the answer in the problem. -55=-55
8.) Your answer is -77
