Answer:

Length = 5x + 3

Width = x  +1

Step-by-step explanation:

Given

Area = 5x^2 + 8x + 3

Required

Determine the dimensions

To do this, we simply factorize the given expression.

Area = 5x^2 + 8x + 3

Expand

Area = 5x^2 + 5x +3x+ 3

Factorize

Area = 5x(x + 1) +3(x+ 1)

Factor out x + 1

Area = (5x +3) (x+ 1)

Area is calculated as:

Area = Length * Width

So:

Length = 5x + 3

Width = x  +1

Step-by-step explanation:

In question 1:

In all cases, the entire population is measured so that the actual medium discrepancy could be measured as well as an interval of trust cannot be used.

This issue would be that she calculated the ages with all representatives of both classes, such that she measured a whole population. It's not necessary.

In question 2:

When the p-value is 0.042. At 90% trust and 92% trust level 11 (p-value below 0.10 and 0.08) are not included. however the biggest confidence level of 92%. Consequently, the largest trust level where the 11 is Not included in the trust interval is 92% trust.
