Answer:

9-2=7

Step-by-step explanation:

The range of a data set is the maximum (highest) value/number subtracted from the minimum (lowest) value. So to find the range of this data set, you subtract the largest number 9 by 2 to get the range of 7.

Answer:

Jay's bread size is 220% of the original size.

Step-by-step explanation:

The question is incomplete.

The complete question is as follows.

Jay is letting her bread rise. After 3 hours,her bread is at 11/5 of its original size. What percent of its original size is jays bread dough?

Solution:

Let the original bread size be = $100$ units

After 3 hours the bread rises = $\frac{11}{5}$ of the original size

New size of bread = $\frac{11}{5}\times 100=220$ units

Percent of original size the new bread is

⇒ $\frac{New\ bread\ size}{Original\ bread\ size}\times 100$

⇒ $\frac{220}{100}\times100$

⇒ $220\%$

Answer:

0.83
0.9
steeper than
slower than

Step-by-step explanation:

Letting t=1 in Ted's equation, we find that he climbs 5/6 stairs in 1 second. As a decimal, 5/6 ≈ 0.83.

Michael climbs 9 stairs in 10 seconds so his rate is ...

... (9 stairs)/(10 seconds) = (9/10) stairs/second = 0.9 stairs/second

Michael's graph will be a line with a slope of 0.9; Ted's graph will be a line with a slope of about 0.83, so the line on Michael's graph is steeper.

Ted climbs fewer stairs per second, so his rate is slower than Michael's.

Comment on the problem

You're being asked to compare two different rates that are associated with two different people. First the comparison is one way, then it is the other way. This can be confusing. It might be helpful to draw and label a simple chart to help you keep it straight. (The attachment is such a chart scribbled on a bit of scratch paper. It is sufficient for the purpose.)
