<span>The one-way ANOVA or one – way analysis of variance is used to know whether there are statistically substantial dissimilarities among the averages of three or more independent sets. It compares the means between the sets that is being examined whether any of those means are statistically pointedly dissimilar from each other. If it does have a significant result, then the alternative hypothesis can be accepted and that would mean that two sets are pointedly different from each other. The symbol, ∑ is a summation sign that drills us to sum the elements of a sequence. The variable of summation is represented by an index that is placed under the summation sign and is often embodied by i. The index is always equal to 1 and adopt values beginning with the value on the right hand side of the equation and finishing it with the value over head the summation sign.</span>

LenaWriter [7]

Answer:

a)

<u>The discount id 40%, so the function is:</u>

  • d = 0.4p

b)

  • p = 100 ⇒ d = 40
  • p = 200 ⇒ d = 80
  • p = 300 ⇒ d = 120
  • p = 400 ⇒ d = 160
  • p = 500 ⇒ d = 200

<em>The graph is attached</em>

c)

  • p = $85 ⇒ d = 0.4*$85 = $34

<u>Sale price is:</u>

  • CP = p - d = $85 - $34 = $51

Greg is designing a clock face. Using the center of the clock face as the origin, he keeps its diameter at 10 units. Match the p
Nat2105 [25]

The center of the clock is taken as the origin.The clock is a circle with a diameter 10 units.Radius is half the diameter .Radius = 10 ÷2= 5 units.

The clock is divided in four quadrants .On x axis y=0 and on y axis x=0.

When it is  12 o'clock the hour hand is on positive of y axis.Coordinates of the point at 12 o'clock=(0,5)

When it is 3 o 'clock the hour hand is on positive of x axis .Coordinate of the point at 3o'clock is (5,0)

When it is 6 o'clock the hour hand is on negative of y axis .The coordinates of the point at 6o'clock is (0,-5)

At 9o'clock the hour hand is on negative of x axis .The coordinate of the point at 6o'clock is(-5,0)
