What is the sign of the product ()(4)?
positive, because the products (3) 3) and (-2)(4) are negativeand the product of two negative numbers is positive
positive because the products () and (-2)(4) are positive and the product of two positive numbers is positive
negative, because the products (3)-3) and (-2)(4) are negative, and the product of tivo negative numbers is negative
negative, because the products (3)-3) and (-2)(4) are positive and the product of two positive numbers is negative

Positive

Explanation;

Positive, because the products (3) (-3) and (-2)(4) are negative and the product of two negative numbers is positive.

When 3 and -3 are multiplied together they give a value of -9 which is a negative value and the product of (-2) and (4) will also give -8 which is also a negative number. Also note that the product of two negative number will give a positive number as such the product of the resulting values which is -9 and -8 will give +72 (which is a positive number).

step-by-step explanation:

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
