1/x^2 / 3/x^3
1/x^2 * x^3/3=x/3
Answer:
To find the mode, order the numbers lowest to highest and see which number appears the most often.
Step-by-step explanation:
A= π r2 and v=3.14d
---Volume(v=3.14d):
3.14(15) equals 47.1
47.1 rounds to 47
nearest hundreth would be 0 that rounds to .1 or .10,which rounds to 47
v=47
---Area(π r2)
3.14(7.5)^2 is 3.14(56.25)
176.625
176.625 rounded to the nearest hundreth is 176.630.
Answer:
The area of a circle with the diameter of 15 is 176.630.
Answer:
a. 0.15%
Step-by-step explanation:
The Z-score of a 945-lb car is ...
(X -μ)/σ = (945 -3550)/807 ≈ -3.23
The empirical rule tells you that about 99.7% of the normal distribution is within 3σ of the mean, so less than 1/2 of 0.3% will be more than 3σ below the mean. The most appropriate of these choices is 0.15%.
_____
The CDF of a normal distribution changes rapidly in the tails, so the difference between 3σ and 3.23σ is pretty large. The actual probability is nearer 0.062%.
