Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y=2x+3$

This is the equation of the line

To graph a line we need two points

<em>Find the intercepts</em>

1) The y-intercept is the value of y when the value of x is equal to zero

For x=0

$y=2(0)+3$

$y=3$

The y-intercept is the point (0,3)

2) The x-intercept is the value of x when the value of y is equal to zero

For y=0

$0=2x+3$

$x=-3/2=-1.5$

The x-intercept is the point (-1.5,0)

To draw the graph of the line plot the intercepts and join the points

using a graphing tool

see the attached figure

Step-by-step explanation:

$\frac{2 + 3i}{4 - 5i}$

$\frac{(2 + 3i)(4 + 5i)}{(4 - 5i)(4 + 5i)}$

$\frac{8 + 10i + 12i + 15 {i}^{2} }{16 - 25 {i}^{2} }$

$\frac{8 + 22i + 15( -1 )}{16 - 25 ( - 1)}$

$\frac{8 - 15 + 22i}{16 + 25}$

$\frac{ - 7 + 22i}{41}$

So, a= -7

b= 22

c= 41

To earn a fitness award, your average heart rate while walking must be between 80 and 89 beats per minute, inclusive. Suppose yo

Morgarella [4.7K]

Based on the first three (3) recordings, your average heart rate in beats per minute is approximately 84 bpm (mean). Calculating for the standard deviation of the samples, we get about 2.5 bpm. To give the possible heart rates on the fourth, we may solve for the range:

Upper Range = Mean + Standard Deviation = 84 + 2.5 = 86.5 bpm or 87 bpm
Lower Range = Mean - Standard Deviation = 84 - 2.5 = 81.5 bpm or 82 bpm

Therefore the fourth and final recording will likely to fall in the range of 82 - 87 beats per minute. You will win the fitness award!

<em>ANSWER: 82-87 beats per minute</em>
