Twenty motors were put on test under a high-temperature setting. The lifetimes in hours of the motors under these conditions are

given below. Suppose we assume that the lifetime of a randomly selected motor under these conditions, X, has a Gamma (1, theta) distribution.
(a) Derive the maximum likelihood estimate of 9 and evaluate it numerically.
(b) Obtain the sample median of the data, which is an estimate of the median lifetime of a motor. What parameter is it estimating (i.e., determine the median of X)?
(c) Based on the mle, what is another estimate of the median of X?
(d) Obtain a large sample approximate 95% confidence interval for the mean lifetime of a motor.

Write it as a decimal

7/81 = 0.0864

0.0864 is the decimal representation for 7/81

For Percentage Conversion :

step 1 To represent 0.0864 in percentage, write 0.0864 as a fraction

Fraction = 0.0864/1

Leslie drank 4/5 pint of juice and Hank drank 7/10 pint of juice. Who drank more
amid [387]
Leslie did. If you multiply 4/5 by two, you get 8/10. 8/10 is greater than 7/10.

What is the easiest way to re learn ratios
enot [183]

Answer:

Step-by-step explanation:

Ratios are no different from fractions. They are "comparisons" of 2 or more things. Instead of fraction bars, they use colons to separate 2 different things.

For example:

\frac{1}{2}=1:2

Now, let's do an example problem.

Ex: find the ratio of 5 cats to every dog.

We are comparing 5 cats to every 1 dog, so the ratio is:

5:1

Don't make thing more complicated to yourself, and don't overthink it. They are exactly like fractions. So treat them as such!

Dina invests $600 for 5 years at a rate of 2% per year compound interest.
kenny6666 [7]

Answer:

The investment after 5 years is $ 662.45.

Step-by-step explanation:

Principal, P = $ 600

Time, t = 5 years

Rate of interest, R = 2 %

Time , t = 5 years

The amount after the time 5 years is

A = P \times \left ( 1+\frac{R}{100} \right )^t\\\\A = 600\left ( 1+0.02 \right )^5\\\\A = 662.45

So, the investment after 5 years is $ 662.45.
