(1/10 * 1/10 * 1/10) = (- 10) ^ 3 Is it true or false

Mathematics
1 answer:
vagabundo [1.1K]2 years ago
4 0

Answer:

  False

Step-by-step explanation:

The exponent signifies repeated multiplication, so will reflect the fact that 1/10 is a factor 3 times.

  (1/10)(1/10)(1/10) = (1/10)^3 . . . not (-10)^3

The given equation is FALSE.

__

This can also be written as 10^(-3), which is perhaps what someone was trying to do. The minus sign goes with the exponent, not the base.

joja [24]

Answer:

First choice:

  • <em><u>Most of the data in each plot are greater than 48.</u></em>

Explanation:

1. Boy's Heights.

Using the information you can create a frequency table:

Heigth    Frequency

40                   0

41                     1

44                    3

46                    3

48                    2

50                    3

52                    4

54                    4

56                    0

58                    0

60                    0

                   ======

                      20 boys

2. Girl's Heights.

Similarly, create your frequency table:

Height        Frequency

40                      0

41                       0

42                      0

44                      2

46                      3

48                       1

50                      3

52                       4

54                       3

56                       4

58                       0

60                       0

                      ======

                        20 girls

<em>Which is a true statement for most of the data in each plot?</em>

<u><em>Most of the data in each plot are greater than 48.</em></u>

  • Count the dots or add the frequencies from the tables.

  • For boys, the frequency of points greater than 48 is: 3 + 4 + 4 = 11 which is more than half (there are 20 dots).

  • For girls, the frequency of points greater than 48 is: 3 + 4 + 3 + 4 = 14, which is also more than half.

Hence, it is correct that most fo the data in each plot are greater than 48.
