Write an expression for the sequence of operation:<br> ) divide the product of a and b by 9
Alisiya [41]

Answer:

  (ab)/9

Step-by-step explanation:

The product of a and b is written ...

  ab

Division by 9 is indicated by a fraction with 9 in the denominator and the dividend in the numerator. In text form, it looks like ...

  (ab)/9

In typeset form it looks like ...

  \dfrac{(ab)}{9}

The parentheses are necessary in both cases if you want to make sure the product is formed before the division occurs. The Order of Operations requires that the contents of parentheses be evaluated first.

On the other hand, in text form, ab/9 is supposed to be evaluated left to right, so the multiplication should occur before the division. (There is no "left to right" for the typeset fraction in the case where there are no parentheses.)

_____

<em>Comment on the question</em>

Technically speaking, There is no way to write the expression so that the multiplication is required before the division, because the associative and commutative properties of multiplication allow the sequence to be rearranged to any convenient order.

You flip 3 coins 20 times and record the number of heads. The results are listed below. 2, 1, 0, 2, 2, 0, 2, 2, 3, 2, 1, 2, 1, 2
BaLLatris [955]

Answer:

You would expect to get 0 heads and 3 heads about the same number of times

This would be a good experiment to use to find the probability that a family with 3 kids has 1 boy

Step-by-step explanation:

Step 1: Construct a frequency table

Number of heads                Tally mark                Frequency

        0                                   II                                      2

        1                                    IIIII II                                7

        2                                   IIIII III                               8

        3                                   II                                      2

Step 2 : Check the statements

<em>You would expect to get 0 heads and 3 heads about the same number of times</em>-True because the frequency of 0 heads is 2 and the frequency of 3 heads is also 2.

<em>You would expect to get 1 head and 2 heads about the same number of times</em>-False because the frequency of getting 1 heads is 7 whereas the frequency of getting 2 heads is 8.

<em>This would be a good experiment to use to find the probability that a family has a dog or a cat</em>-False because the experiment done above has 3 objects (3 coins) whereas this experiment has just 2 objects (cat and dog).

<em>This would be a good experiment to use to find the probability that a family with 3 kids has 1 boy</em>-True because both experiments have 3 objects and just like we found the frequency of getting 1 heads, we can find the frequency of getting 1 boy out of 3 kids.
