Answer:

Step-by-step explanation:

6+3x=27

-6 for both sides

3x=21, divide both by 3

x=7

so 2x would be 14 as 2*7 equals 14

Help ! Inductive and deductive reasoning differ in which way? A) Conclusions drawn using deductive reasoning are always false, w
kykrilka [37]

Answer:

B) Conclusions drawn using inductive reasoning are always valid, while conclusions drawn using deductive reasoning may or may not be valid.

Step-by-step explanation:

Inductive reasoning uses logic and uses more evidence to draw conclusions. In deductive reasoning, WE decide whether a deductive statement is true by assessing the strength of the link between the premises and the conclusion. But some deductive reasoning may appear to make sense without pointing to a truth

inn [45]

Answer:

In the graph we can find two points, lets select:

(2, 15) and (4, 30)

Those are the first two points.

Now, for two pairs (x1, y1) (x2, y2)

The slope of the linear equation y = s*x + b that passes trough those points is:

s = (y2 - y1)/(x2 - x1)

So the slope for our equation is

s = (30 - 15)/(4 - 2) = 15/2

then our linear equation is

y = (15/2)*x + b

now we can find b by imposing that when x = 2, y must be 15 (for the first point we selected)

15 = (15/2)*2 + b = 15 + b

b = 15 - 15 = 0

then our equation is:

y = (15/2)*x

Where we used a division and a multiplication.

If enrollment increases by approximately the same
Tanya [424]

Given:

The enrollment increases by approximately the same percentage between 2000 and 2010 as it decreased between 1950 and 1960.

To find:

The expected enrollment in 2010.

Solution:

Percentage decrease formula:

\%\text{ decrease}=\dfrac{\text{Initial value - New value}}{\text{Initial value}}\times 100

The percentage decrease in between 1950 and 1960 is:

\%\text{ decrease}=\dfrac{4-3.5}{4}\times 100

\%\text{ decrease}=\dfrac{0.5}{4}\times 100

\%\text{ decrease}=\dfrac{50}{4}

\%\text{ decrease}=12.5

The enrollment decreased by 12.5% between 1950 and 1960. So, the enrollment increases by 12.5% between 2000 and 2010.

The expected enrollment in 2010 is:

\text{Expected enrollment}=7+\dfrac{12.5}{100}\times 7

\text{Expected enrollment}=7+0.875

\text{Expected enrollment}=7.875

Therefore, the expected enrollment in 2010 is 7.875 thousands.
