Yoshi is testing how being exposed to pictures of different types of foods affects sleepiness. He shows each participant five pictures of dessert, five pictures of entrees, and five pictures of salads, and then he measures sleepiness after each group of five pictures. To eliminate order effects, Yoshi creates all possible sequences for presenting the three types of food and all five pictures in each type. He then randomly assigns each participant to a sequence. What technique is Yoshi using to prevent order effects

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

where's the diagram?

step-by-step explanation:

0.85% : )

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
