Answer:
73.1 inches
Step-by-step explanation:
We solve for this using z score formula.
z-score is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
x = unknown = randomly selected male's height
μ = 70.3 inches
σ = 4.1 inches
z = is not given but we are given its percentile which is 75
The z score for a 75th percentile = 0.674
Hence,
0.674 = x - 70.3/4.1
Cross Multiply
0.674 × 4.1 = x - 70.3
2.7634 = x - 70.3
x = 70.3 + 2.7634
x = 73.0634 inches
The height of the randomly selected male = 73.0634
Therefore, the height of the randomly selected male to the nearest tenth of an inch is 73.1 inches
Answer:
6x = 3/8x + 4
Step-by-step explanation:
The product of a number (x) and 6 ... 6x
is ... =
four more than ... ___ +4
the product of the number and 3/8 ... 3/8x . . . . (goes in the blank that is added to 4).
Thus, this statement is directly translated to ...
... 6x = 3/8x + 4
Its 1 5/6 hope this helps
