Answer: 1/20
Step-by-step explanation:
Number of lemonades = 1
Total number of drinks = 20
Therefore, the probability that the next drink that's sold will be lemonade will be:
= Number of lemonades / Total drinks
= 1/20
Therefore, the answer is 1/20
Given Sarah could rum 800m in 3 minutes and 20 seconds = 3*60+20 = 200 seconds when she was in year 8.
Where as she could run 800m in 2 minutes 44 seconds = 2*60+44=164 seconds.
Percentage improvement in her time = (difference in time/ original time) * 100
Hence there is an improvement of 18% in her time.
Yes I think but be smart and don't use may answer
Answer:
12
Step-by-step explanation:
substitute b = 3 and c = 4 into the expression
8b - 3c
= 8(3) - 3(4)
= 24 - 12
= 12
Answer:
a. 6
b. 12
c.
Step-by-step explanation:
a. Using two pairs of values given, (0, 12) and (1, 18)
Rate/slope =
Unit rate/slope (m) = 6
b. The starting value is the y-intercept (b). It is the value of of y when x = 0.
From the table, when x = 0, y = 12.
Therefore the starting value (b) would be 12.
c. The equation can be written in slope-intercept form, , where,
m = slope/rate = 6
b = starting value/intercept = 12.
Plug in the values into the equation
The equation would be:
