What is the cube root of 27x18?

Tanzania [10]

To avoid multiplying the two numbers and then finding the cube root, find the cube root of each number first. the cube root of 27 is 3x3x3, so you can take out the three to outside of the sqrt, to get 3 cube root 18. eighteen does not have a cube root, so that's all you have to do. the answer would be 3 (cube root) 18.

The length of time needed to complete a certain test is normally distributed with mean 46 minutes and standard deviation 6 minut

madam [21]

Answer:

0.0668 or 6.68%

Step-by-step explanation:

Mean time (μ)= 46 minutes

Standard deviation (σ) = 6 minutes

The z-score for any given time X is determined by:

$z=\frac{X-\mu}{\sigma}$

For X = 37:

$z=\frac{37-46}{6}\\ z=-1.5$

A z-score of -1.5 corresponds to the 6.68th percentile of a normal distribution. The probability that it will take less than 37 minutes to complete the test is

$P(X\leq 37) = 0.0668=6.68\%$

The probability is 0.0668 or 6.68%
