You're assuming that this data set represents all of Mrs. Hassaan's pupils. Certain students could be missing from the histogram - for instance, there could be one or two students who missed the test, but for certain reasons will be taking a make-up exam. Their grade would not be recording in this data set, but they still contribute to the class size, and so would be unaccounted for here.

Answer:

In other words, $100 in 1987 is equivalent in purchasing power to about $227.09 in 2020, a difference of $127.09 over 33 years. The 1987 inflation rate was 3.65%. The current inflation rate (2019 to 2020) is now 2.49%

9. Determine whether (-3,2) is a solution of<br> Y = 2x +8<br> Y= -X+1

miss Akunina [59]

2 = 2(-3) + 8
2 = -6 + 8
2 = 2

true.

2 = 3 + 1
2 = 4

false.

this is not a solution because both equations have to be true.

Resuelve con calculadora y escribe la regla utilizada

$36\times 100 = 3600\\\\8 \times 1000 = 8000\\\\5.6 \times 10 = 56\\\\5.6 \times 100 = 560\\\\5.6 \times 1000 = 5600\\\\2.12 \times 100 = 212$

When you multiply by 10, 100, or 1000, you must move the decimal place over by how many zeroes there are. Once there is no more decimals, you add 0's to the end of the number until you are done.

For example, 5.6 x 1000

1000 has 3 zeroes.

That means we need to move the decimal spot 3 times.

5.6 x 1000 = 56 x 100

We got rid of the decimal but we still have 2 zeroes left. So now we just add 2 zeroes at the end of the number.

5.6 x 1000 = 56 x 100 = 5600

I hope that helps! :)
