Answer:

standard deviation of the distribution = 6.325.

Step-by-step explanation:

i) standard deviation of the population σ = 20

ii) size of sample n = 10.

iii) standard deviation of the distribution = \frac{\sigma}{\sqrt{n}} = \frac{20}{\sqrt{10}} = \frac{20}{3.162} = 6.325

Answer:

  • y = 0.35x

Step-by-step explanation:

<u>Janet ⇒ 3 postcards ⇒ $1.05 </u>

  • Cost of postcard: 1.05/3 = $0.35

<u>Rosi ⇒ 5 postcards ⇒ $1.75 </u>

  • Cost of postcard: 1.75/5 = $0.35

<u>Tanya ⇒ 8 postcards ⇒ $2.80</u>

  • Cost of postcard: $2.80/8 = $0.35

<u>We see in all 3 cases cost of postcard is same, the cost and numbers are proportional and the relationship is:</u>

  • y = 0.35x

Find an equation of a line that goes through the points (1,6) and (4, -2). Write your answer in the form y=mx + y.
zmey [24]

Answer:

The desired equation is y = (-8/3)x + 26/3.

Step-by-step explanation:

Moving from (1,6) to (4, -2) involves an increase of 3 in x and a decrease of 8 in y.  Thus, the slope of the line thru these two points is m = rise / run = -8/3.

Using the slope-intercept form of the eq'n of a straight line  and inserting the data given (slope = m = -8/3, x = 4,  y = -2), we get:

y = mx + b => -2 = (-8/3)(4) + b, or  -2 = -32/3 + b

Multiply all terms by 3 to clear out the fraction:

-6 = -32 + 3b.

Then 26 = 3b, and b = 26/3.

The desired equation is y = (-8/3)x + 26/3.
