A line passes through (-9,-5) and (2,-4)
zlopas [31]

The point-slope form of a line:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-9, -5) and (2, -4). Substitute:

m=\dfrac{-4-(-5)}{2-(-9)}=\dfrac{1}{11}\\\\y-(-5)=\dfrac{1}{11}(x-(-9))\\\\\boxed{y+5=\dfrac{1}{11}(x+9)}\leftarrow\boxed{\text{point-slope form}}

The standard form of a line:

Ax+By=C

y+5=\dfrac{1}{11}(x+9)                <em>multiply both sides by 11</em>

11y+55=1(x+9)

11y+55=x+9     <em>subtract 9 from both sides</em>

11y+46=x      <em>subtract 11y from both sides</em>

46=x-11y

\boxed{x-11y=46}\leftarrow\boxed{\text{standard form}}

Laura shades 60 squares on her hundredths grid And Billy shades 50 squares on his hundredths grid. Write the decimal number that
Andre45 [30]

Answer:

Laura = 0.60

Billy = 0.50

0.60 > 0.50

Step-by-step explanation:

Given

Laura = 60\ shades

Billy = 50\ shades

Required

Represent using decimal number and compare

From the question, we understand that there are 100th grids;

So:

Laura = \frac{60}{100}

Laura = 0.60

Billy = \frac{50}{100}

Billy = 0.50

Comparing both decimals;

Since 0.60 is greater than 0.50, we have:

0.60 > 0.50

Is it unusual for the sampling mean to be exactly the same as the population mean?
8090 [49]

Answer:

NO

Step-by-step explanation:

This is because the sample should ideally be representative of the whole population. If the right sampling methods are used, the sample should well exhibit the properties of the whole population.  The sample mean should be as precise as possible to the population mean , hence it is not unusual for the sampling to mean to be exactly the same as the population mean
