John will need to sleep for 10.3 hours before his second exam so that the
average of his two exam scores is an 80.
We were given
8 hours of sleep = 70
To get average of 80
<u>70+ x</u> = 80
2
Cross multiply:
70+x = 160
x= 160-70
= 90.
If 8 hours of sleep = 70
x hours of sleep = 90
Cross multiply
8× 90 = 70 × x
720 = 70x
x = 720/70
x = 10.2857
≈ 10.3 hours of sleep

The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s
<h3>
Velocity function </h3>
Given the equation for the position of the mouse expressed as:
The velocity of the particle is expressed as:
Given that p = 0. 40 m/s and q = -1. 10 m/s, the equation will become:
If the time is <em>t = 1.0 s, the velocity will be:</em>
Similarly if t = 4.0ssec, hence:
The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s

Complete question
<em>A mouse runs along a baseboard in your house. The mouse's position as a function of time is given by x(t)=pt 2+qt, with p = 0.40 m/s2and q = -1.10 m/s . Determine the mouse's average speed between t = 1.0 s and t = 4.0 s. I have tried everything and the answer is not 0.40 m/s</em>
Machine learning (ML) data can be represented in the following forms:
1. Matrix and Spatial.
2. Scalar and Vector.
Machine learning (ML) is also referred to as Artificial intelligence (AI) and it can be defined as a subfield in computer science which is focused on the use of computer algorithms to build a smart computer-controlled robot that has the ability (capacity) to automatically perform and handle tasks that are exclusively designed to be performed by humans or by using human intelligence.
Generally, the data that are generated and used in machine learning (ML) can be represented in the following forms:
