Explain how deductive reasoning is used to prove an argument.

Mathematics

sineoko [7]3 years ago

Deductive reasoning is what is proven and what you already know for sure. Example: there are 2 ants. There is 1 ant next to the 2. There are 3 ants total. (Rules of addition)

So you don't have to solve any problems to use deductive reasoning, unlike inductive reasoning, which is not proven
Example of inductive reasoning: there are lots of girls in my class. So there are probably lots of girls in the other classes too. You don't know that for sure.

Please please please help me with this assignment :)
Shtirlitz [24]

Answer:

$45.63

Step-by-step explanation:

50,145 cm^{3}  *  2.6 g/cm^3 = 130,377 g\\130,377 g = 130.377 kg\\130.377 kg * $0.35/kg = $45.63\\

or all together    

50,145 cm³  *  2.6 g/cm³ * 0.35/kg =  $45.63

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different
aev [14]

Answer/Step-by-step explanation:

✍️The equation of the line in point-slope form:

The equation is given as y - b = m(x - a), where,

(a, b) = a point on the line.

slope (m) = \frac{y_2 - y_1}{x_2 - x_1}

Let's find the slope (m) of the line, housing (3, 21) and (6, 12):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 21}{6 - 3} = \frac{-9}{3} = -3

Substitute a = 3 and b = 21, m = -3 into y - b = m(x - a).

Thus, the point-slope equation would be:

✅y - 21 = -3(x - 3)

✍️The equation of the line in slope-intercept form:

Rewrite y - 21 = -3(x - 3), so that y is made the subject of the formula.

y - 21 = -3x + 9

Add 21 to both sides

y = -3x + 9 + 21

y = -3x + 30

✅The slope-intercept equation of the line is y = -3x + 30

Where,

-3 = how much did his delivery time decrease per day (slope)

30 = how long it initially took Peter to deliver his packages (y-intercept)

During a test period, an experimental group of 10 vehicles using an 85 percent ethanol-gasoline mixture showed mean CO2 emission
Aleksandr-060686 [28]

Answer:

Probably unequal  ( B )

Step-by-step explanation:

<u>experimental group = 10</u>

using 85% ethanol gasoline

mean = 240 pounds per 100 miles

standard deviation = 20 pounds

<u>control group = 14 vehicles </u>

using regular gasoline

mean = 252 pounds per 100 miles

standard deviation = 15 pounds

comparing  the sample variance of each group shows that they are probably unequal using the equation below

Variance for a sample set of data = ∑ ( x - X ) ^2 / n - 1

where n = number of events

X = mean value

x = value of events
