We have that
Log3 a/3
Rewrite log3(a/3) using the change of base formula

we know that
The change of base rule can be used if a and b are greater than 0 and not equal to 1, and x is greater than 0.
so
loga(x)=logb(x)/logb(a)
Substitute in values for the variables in the change of base formula

in this problem
b=10
a=3
x=a/3

log3(a/3)=[log (a/3)]/[log (3)]

the answer is
[log (a/3)]/[log (3)]

Step-by-step explanation:

$1\sqrt{12} * 1\sqrt{2}$

$\sqrt{12} * \sqrt{2} = \sqrt{24}$

$\sqrt{24} = \sqrt{2^2 * 6} = 2\sqrt{6}$

Approximately how many kcal are contained in 3 ounces of 80-proof rum?

Mekhanik [1.2K]

3 ounces of 80-proof rum approximately contains 200,000 cal.

Now, we need to convert the cal into kcal. We know that:
1 cal = 1000 kcal
Therefore,
200,000 cal = 200 kcal

in 2018 GRE scores were normally distributed with a mean of 303, and standard deviation of 13. Standford University Graduate sch

eduard

Answer:

The minimum score needed to be considered for admission to Stanfords graduate school is 328.48.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 303, \sigma = 13$
