When jim surveyed 5 sixth-grade students at the community skating rink, he found that only 1 out of the 5 had completed the science project. he knows there are about 160 sixth-grade students in his community, so he infers that around 32 students have finished their science project. is this a good inference?

No, Jim did not make a good inference.

Step-by-step explanation:

Given: Jim surveyed  only 5 sixth-grade students at the community skating rink, he found that only 1 out of the 5 had completed the science project.

⇒ Sample space = 5

His interference was 32 students have finished their science project if  160 sixth-grade students in his community.

But the sample space (5) is too small and it can be biased as he only asked students at the community skating rink.

Therefore, Jim did not make a good inference.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

probably .5

i can on others if necessary.
