Lets first convert 7 MiB to bits
bits
Now convert bits to Gbits
Gbits
Queuing Delay = Total size/transmission link rate
Queuing Delay=
seconds
Delay of packet number 3 =

or
milliseconds
Answer:
Following are the code in the PHP Programming Language:
<u>foreach ($country_codes as $code => $name) {
</u>
Explanation:
The following option is true because the Foreach statement only works on the objects and array and this statement is good for accessing the key and value pairs from the array.

Answer:
a. This is an instance of overfitting.
Explanation:
In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.
