Answer:
4 x 3
Step-by-step explanation:
The order of a matrix is given by stating the number of rows followed by the number of columns.
The matrix here has 4 rows and 3 columns thus order is
4 x 3
Answer:
Step-by-step explanation:
<u><em>Note:</em></u><em> It seems typo in the question. 5% should read 59.</em>
Let 3 credit courses = x, 4 credit courses = y
<u>As per given we have following equations:</u>
<u>Solve the system by elimination. Multiply the first equation by 4 and subtract the second one:</u>
- 4(x + y) - (3x + 4y) = 4(18) - 59
- 4x + 4y - 3x - 4y = 72 - 59
- x = 13
The answer is 13
Correct choice is A
Answer:
The least squares method results in values of the y-intercept and the slope, that minimizes the sum of the squared deviations between the observed (actual) value and the fitted value.
Step-by-step explanation:
The method of least squares works under these assumptions
- The best fit for a data collection is a function (sometimes called curve).
- This function, is such that allows the minimal sum of difference between each observation and the expected value.
- The expected values are calculated using the fitting function.
- The difference between the observation, and the expecte value is know as least square error.
Answer:
A
Step-by-step explanation:
Remember that 
x^(b-c)
Using that 
=3^(1/2x-1/2)=3^((x-1)/2)
So we can say: 
, because the bases are the same
We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.
