Answer:
y = 3/4x -7/4 or y = 0.75x -1.75
Step-by-step explanation:
The two point form of the equation of a line is useful when you are given 2 points and asked for the equation.
y = (y2 -y1)/(x2 -x1)·(x -x1) +y1
y = (35 -14)/(49 -21)·(x -21) +14 . . . . . . fill in given points
y = 21/28(x -21) +14 . . . . . . . . . . . . . . . simplify a bit
y = 3/4(x -21) +14 . . . . . . . . . . . reduce the fraction
y = 3/4x -15 3/4 +14 . . . . . . . .eliminate parentheses
y = 3/4x -7/4 or y = 0.75x -1.75
Answer:
The perimeter of the larger sign : 144*1,25= 180 inches
Side of the triangle= 180/3= 60 inches
square of the height= 60^(2) - 30^(2)= 2700 ( Pythagoras' theorem)
height= square root ( 2700)= 51,96
Step-by-step explanation:
Answer:the area of their front yard and side yards is:
2*3*10 + 9*9 = 141 m^2
They do not need to reseed a proportion of the front yard covering 16 square meters where a flower bed is located:
141 - 16 = 125 m^2 is the area of the yard that the Solomon's want to r

Answer:
C. To control both unintentional research bias and participant prior beliefs
Step-by-step explanation:
Double blinding is a type of study where neither the participants nor the researchers know the treatment or intervention that the participants receive until the whole study/research is completed. This is very important because it means that the results gotten from the study have a very slim chance of being biased.
Thus,the correct answer is option C as it includes both the researcher and the participants
Whole numbers is the correct answer
