Mika is a local farmer who is interested in how often residents in her town go to a farmer's market each month. She surveys 124
TEA [102]

Answer:

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Step-by-step explanation:

Margin of error

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation and n is the size of the sample.

Standard deviation of 1.3

This means that \sigma = 1.3

She surveys 124 families

This means that n = 124

Margin of error and meaning:

M = z\frac{\sigma}{\sqrt{n}}

M = 2.58\frac{1.3}{\sqrt{124}}

M = 0.3012

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Could you please help me with questions 36 &amp; 37?
Andrej [43]

We have to determine if the functions are linear or not.

We can do this by rearranging the equations in this form:

y=mx+b

where m and b are constants.

<em>NOTE: There are many ways to prove that a function is linear, but this is the easiest for this question. </em>

36.

\begin{gathered} x+\frac{1}{y}=7 \\ \frac{1}{y}=-x+7 \end{gathered}

As this function can not be written in the form y=mx+b, then it is not linear.

37.

\begin{gathered} \frac{x}{2}=10+\frac{2y}{3} \\ \frac{x}{2}-10=\frac{2y}{3} \\ \frac{2y}{3}=\frac{1}{2}x-10 \\ y=\frac{3}{2}(\frac{1}{2}x-10) \\ y=\frac{3}{4}x-15 \end{gathered}

This function is now in the form y=mx+b, where m=3/4 and b=-15. Then, this function is a linear function.

Answer:

36. Non-linear.

37. Linear.

The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 40 cm, find its area
mel-nik [20]

Answer:

96

Step-by-step explanation:

The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 40 cm, find its area

width + 4 = length

width = width

2l + 2w = p

width+width +width +width +4 +4 = 40

4width +8  = 40

4width =  32

width = 8

length x width = area

width = 8

length = 12 (width + 4)

12x 8 =  96
