Answer:
P(candy chosen is red) = 58/200
Step-by-step explanation:
y=2
Step-by-step explanation:
Make an equation of straight line by using the formula :y= mx+c
put the x-value of point (2,4) which is 2 and the gradient,m which is 2 into the straight line equation:
y=2x +c
So you need to find the y-intercept to complete the equation, therefore:
when y=0,
0=2(2)+c
c=-4
next the question ask to find the y-coordinate when x =3, therefore you just need to replace x in the equation with 3:
y=2(3)-4
y=4
Answer:
21
Step-by-step explanation:
all you have to do is get 70% of 30
70% of 30 is 21
Answer:
75%.
Step-by-step explanation:
In total, there are 3 gnarly boards in the first shop and 1 gnarly board in the second. We know that he has selected one gnarly board out of the 3 + 1 = 4 existing boards.
The probability the board came from the first shop is 3 / 4 = 0.75 = 75%.
Hope this helps!
Answer:
16.38 meters represents the greatest amount of change in her depth over a single 5-minute period
Step-by-step explanation:
From time = 0 to time = 5 the amount of change in her depth was -12.45 - 0 = -12.45 meters
From time = 5 to time = 10 the amount of change in her depth was -9.7 - (-12.45) = -2.75 meters
From time = 10 to time = 15 the amount of change in her depth was -22.98 - (-9.7) = -13.28 meters
From time = 15 to time = 20 the amount of change in her depth was -6.6 - (-22.98) = 16.38 meters
