Answer:
Step-by-step explanation:
Select the correct answer from each drop-down menu.
We solve using z score formula
z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
The average time taken to complete a test follows normal probability distribution with a mean of 70 minutes and a standard deviation of 25 minutes.
a) The probability of a randomly selected student completing the test in 45 minutes or less is approximately equal to %.
z = 45 - 70/25
b) The probability of a randomly selected student completing the test in 95 minutes is %.
z = 95 - 70/25
Answer:
150
Step-by-step explanation: multiply 10 and 12 and get your rectangle area then multiply .5( 10 and 6) then add them together and get 150
R = robins cans
s = sara's cans
n = nick's cans
T = total cans
s = 5r
n = 6r
T = 216 = s + r + n
we sub in the first two equations into the first
216 = 5r + 6r + r
216 = 12r
r = 18
sub this back into equations 1 and 2
thus
r = 18
s = 90
n = 108
You would most likely use lettuce leaves, because grapes are little orbs of fruit with no leaves, zuchini are funny shaped veggies, and hibiscus is a type of tree. So, the most logical answer would be lettuce leaves.
