4 for 16 would be written as 4/16.
Dividing both numbers by 4 it is simplified to 1/4
Answer:
is it right question or not tell me and I will solve it
6×100+6×90+6×8 I think that is the answer
Answer:
the answer is the first one
Step-by-step explanation:
39.99 rounded up is 40.00
19.99 rounded up is 20.00
40.00*0.05 = 2, 40-2 = 38
20.00*0.15 = 3, 20-3 = 17*.05 = 0.85, 17-0.85 = 16.15
38+16.15 = 54.15
Answer:
0.07378
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ/√n, where
x is the raw score = 65 inches
μ is the population mean= 64.5 inches
σ is the population standard deviation = 2.99
n = 75
z = 65 - 64.5 /2.99/√75
z = 0.5/0.345255461
z = 1.4482
Probability value from Z-Table:
P(x<25) = 0.92622
P(x>25) = 1 - P(x<25)
= 1 - 92622
= 0.07378
The probability that the mean height for the sample is greater than 65 inches is 0.07378
