Answer:
The probability that a randomly selected boy in secondary school can run the mile in less than 302 seconds is 0.0107
Step-by-step explanation:
Consider the provided information.
It is given that mean is 440 seconds and standard deviation is 60 seconds.
z factor for less than 302 seconds would be:
z = (302 - 440) / 60 = -2.3
The probability of getting a z factor of less than -2.3 = 0.0107 approximately.
looking up in the z-table for a z factor of -2.3.
The probability of a student running the mile in less then 302 seconds would be 0.0107.
Hence, the probability that a randomly selected boy in secondary school can run the mile in less than 302 seconds is 0.0107
15/35 = y/84
to find what value of y makes the proportion true, you actually just need to solve for y.
15/35 = y/84 ... first, multiply both sides by 84
(15*84)/35 = y
1260/35 = y
36 = y
so, these values are proportional when y = 36. you can check this by getting the decimal of both and seeing if they're equal:
(15/35) = 0.428
(36/84) = 0.428
Answer:
To get this answer you will need to find the area of the whole shape will be 4y+3*2y=10x. With this, you then have to divide by 2 which will give you 5x. Then you solve for the shaded region which will be 36
