One the first problem on finding the constant of <span> proportionality in this situation the answer is 2. Below is the solution:
constant = unit rate
unit rate = $2/ poung
K = 2
For the second question, the equation is the below:
T = 2p or y = 2x</span>
Answer:
y=1/2x+1
Step-by-step explanation:
one dot on the 1 on the y axis
then more one unit up and two units to the left
and then from the first point (0,1) go one unit down
and two to the right. then make the line with the three points
Answer:
ans: ii) 87° and iii) 60°
Step-by-step explanation:
ii)
y° = 180° - ( 56° + 37°)
missing angle on triangle is alternate angle of y° so are equal and sum of angles of triangle is 180°
iii)
x° + 2x° = 180°
sum of co interior angles is 180°
Answer:

Step-by-step explanation:
-Probability is the likelihood of an event occurring.
-The total number of events is:

-The total number of blue events is:

#Probability of a blue is thus calculated as:

Hence, the probability of choosing a blue marble at random is 37.5%
