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 = ![\frac{\text{Frequency}}{\text{Total of frequencies}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BFrequency%7D%7D%7B%5Ctext%7BTotal%20of%20frequencies%7D%7D)
0.13 = ![\frac{x}{200}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B200%7D)
x = 200 × 0.13
x = 26
Therefore, number of shoppers who are men and prefer mineral water = 26

As we know that one million is 1,000,000.
So we can write it as:-
➢ 1×10⁶
Answer:
- small: 5 yards
- large: 8 yards
Step-by-step explanation:
Using s and L to represent the amount of ribbon used for small barrettes and large barrettes, respectively, we have ...
12s +12L = 156
10s +11L = 138
Dividing the first equation by 12 gives ...
s +L = 13
Substituting s = 13-L into the second equation gives ...
10(13 -L) +11L = 138
130 +L = 138 . . . . . . . simplify
L = 8 . . . . . . . . . . subtract 130
s = 13 -8 = 5 . . . . find s
Rachel uses 5 yards for a small barrette, and 8 yards for a large barrette.
I don't know all, that would take too long, but the first one is C3
