To find the scale factor divide the bigger measurement by the smaller one. 

You did number 17. 42 / 3 = 14 so your scale factor is 14, option D.

For number 18, 48 / 6 = 8 so option A.

tensor-on-tensor regression: riemannian optimization, over-parameterization, statistical-computational gap and their interplay
Contact [7]

The purpose of the tensor-on-tensor regression, which we examine, is to relate tensor responses to tensor covariates with a low Tucker rank parameter tensor/matrix without being aware of its intrinsic rank beforehand.

By examining the impact of rank over-parameterization, we suggest the Riemannian Gradient Descent (RGD) and Riemannian Gauss-Newton (RGN) methods to address the problem of unknown rank. By demonstrating that RGD and RGN, respectively, converge linearly and quadratically to a statistically optimal estimate in both rank correctly-parameterized and over-parameterized scenarios, we offer the first convergence guarantee for the generic tensor-on-tensor regression. According to our theory, Riemannian optimization techniques automatically adjust to over-parameterization without requiring implementation changes.

Construct a 99% confidence interval for the population standard deviation of white blood cell count (in cells per microliter). A
kogti [31]

Answer:

The correct option is 1.148 < σ < 6.015

Explanation:

The 99% confidence interval for the standard deviation is given below:

\sqrt{\frac{(n-1)s^{2}}{\chi^{2}_{\frac{0.01}{2} }} }

Where:

\chi^{2}_{\frac{0.01}{2} }=18.548

\chi^{2}_{1-\frac{0.01}{2}}=0.676

Therefore, the 99% confidence interval is:

\sqrt{\frac{(7-1)2.019^{2}}{18.548} }

1.148

Therefore, the option 1.148 < σ < 6.015 is correct

Julissa is running a 10-kilometer race at a constant pace. After running for 18 minutes, she completes 2 kilometers. After runni
allochka39001 [22]

After running for 18 minutes, Julissa completes 2 kilometers. If she is running a 10-kilometer race at a constant pace, then she comletes 1 kilometer after running 9 minutes. Now you can find the distance she run after 1 minute. This is \dfrac{1}{9} km.

Let t be the time in minutes. Then k, the number of kilometers, can be found from proportion:

\dfrac{1}{9}\ km - 1 minute

k km - t minutes.

Thus,

\dfrac{\dfrac{1}{9}}{k}=\dfrac{1}{t},\\ \\k=\dfrac{1}{9}\cdot t.

Answer: k=\dfrac{1}{9}\cdot t.

Expand (3x+7)(3x-7) =
saveliy_v [14]

Answer:

9 {x}^{2}  - 49

Step-by-step explanation:

Do FOIL, first outside inside last

3x × 3x = 9x^2

3x × -7 = -21x

7 × 3x = 21x

7 × -7 = -49

9 {x}^{2}   - 21x + 21x - 49 \: midde \: cancels \: each \: other \: out

So it would just be 9x^2 - 49
