1. using 2 dots that are on the blue line (0,72) and (6,69)
find the slope:

slope = change in Y over change in x = 69 - 72 / 6-0 = -3 / 6 = -1/2
equation would be y = -1/2x + 72

2. y = -1/2x+72 = -1/2(30) +72 = -15 +72 = 57 beats per minute

3. replaced x in the equation with 30 to find the beats per minute for exercising 30 minutes

-3B+5=13<br> How do I solve for B

Eddi Din [679]

Answer:

b = -2 2/3

Step-by-step explanation:

Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 5 from both sides:

-3b + 5 (-5) = 13 (-5)

-3b = 13 - 5

-3b = 8

Next, divide -3 from both sides:

(-3b)/-3 = (8)/-3

b = -8/3

b = -2 2/3

SIMILARITIES
Some similarities are that for linear and non-linear systems of equations, you need the same number of equations as unknowns to solve the system and find the only solution for each variable.
DIFFERENCES
Some differences are
The linear system of equations has degree "1" in each of its variables.
The non-linear system of equations has degree "n" in each of its variables.
where n = 1,2,3, ..., i, ..., n.

Ian and Danny work for a construction company. The table shows their daily wages (in dollars) for a week picked randomly from th

Crank

Answer:

a) Mean

b) Ian earned higher wages than Danny during the days listed

Step-by-step explanation:

Ian and Danny work for a construction company. The table shows their daily wages (in dollars) for a week picked randomly from the calendar year. Ians Wages ()DannysWages() 96 153 120 89 114 91 111 96 106 129 123 94 110 99 The best way to compare Ians and Danny's wages is by using the ______ as the measure of center. Comparing this measure of center of the two data sets indicates that ______ generally earned higher wages during the days listed.

a) The mean also known as average is one of the most common used measure of center of the data. To calculate the mean, you sum all the data and then divide the total sum by the total number of data values.

b) For Ian's wages, the mean (μ) is calculated as:

$\mu=\frac{96+120+114+111+106+123+110}{7}=111.43$

The mean of Ians wages is $111.43

For Danny's wages, the mean (μ) is calculated as:

$\mu=\frac{153+89+91+96+129+94+99}{7}=107.29$

The mean of Danny's wages is $107.29

From the two data sets, Ian earned higher wages than Danny during the days listed
