1 answer:
Anuta_ua [19.1K]3 years ago

Answer:

10.-8/-2 can't represent calculating a mean change in score because a mean change in score is counted by adding up the scores & then dividing it by the number of the scores. As a number of scores can never be negative, so -8 can't be divided by -2 . So, -8/-2 can't represent this.

6. a) Andrea's mean weekly change will be negative. Because after adding up her weekly changes, we'll find a negative number. & as the number of weeks is positive, then the mean will be a negative number .

b)the division equation is: -15/5

So, her mean weekly change is -3

A 10 pound bag of grapes costs $14.00. How much is it for 1 pound of grapes?
patriot [66]

Answer:

1.40

Step-by-step explanation:

I feel if you divide $14.00 by 10 you would get 1.40, so  I say this should be the right answer.

I apologize if I am incorrect.

A sports teacher had 1025 sweets. After distributing these equally amongst all the participants in a sports meet, he had just 1
Cerrena [4.2K]

Step-by-step explanation:

Since it remains only 1 sweet, we can subtract it from the total and get the amount of sweets distributed (=1024).

As all the sweets are distributed equally, we must divide the number of distributed sweets by all its dividers (excluding 1024 and 1, we'll see later why):

1) 512 => 2 partecipants

2) 256 => 4 partecipants

3) 128 => 8 partecipants

4) 64 => 16 partecipants

5) 32 => 32 partecipants

6) 16 => 64 partecipants

7) 8 => 128 partecipants

9) 4 => 256 partecipants

10) 2 => 512 partecipants

The number on the left represents the number of sweets given to the partecipants, and on the right we have the number of the partecipants. Note that all the numbers on the left are dividers of 1024.

Why excluding 1 and 1024? Because the problem tells us that there remains 1 sweet. If there was 1 sweet for every partecipant, the number of partecipants would be 1025, but that's not possible as there remains 1 sweet. If it was 1024, it wouldn't work as well because the sweets are 1025 and if 1 is not distributed it goes again against the problem that says all sweets are equally distributed.
