Beatrice calculated the slope between two pairs of points.

kumpel [21]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope between (-3, -2) and (1, 0)

$m=\frac{0+2}{1+3}$

$m=\frac{2}{4}=\frac{1}{2}$

Find the equation of the line

$y-y1=m(x-x1)$

with m and the point (1,0)

substitute

$y-0=\frac{1}{2}(x-1)$

$y=\frac{1}{2}x-\frac{1}{2}$

step 2

Find the slope between (-2, -1) and (4, 2)

$m=\frac{2+1}{4+2}$

$m=\frac{3}{6}=\frac{1}{2}$

Find the equation of the line

$y-y1=m(x-x1)$

with m and the point (4,2)

substitute

$y-2=\frac{1}{2}(x-4)$

$y=\frac{1}{2}x-2+2$

$y=\frac{1}{2}x$

<em>Compare the equation of the two lines</em>

The two lines are parallel, because their slope is the same, but are different lines

therefore

Beatrice's conclusion is incorrect

All of these points are not on the same line, because are different parallel lines

The slope between (-2,-1) and (1,0) is equal to $\frac{1}{2}$

You randomly draw a marble out of a bag that contains 20 total marbles. 12 of the marbles in the bag are blue.

Advocard [28]

Answer:

$P(Blue)=0.60$

Step-by-step explanation:

Probability: $Probability\ of\ an\ event=\frac{favourable\ outcome}{total\ outcome}$

$Total\ marbles=20\\\\Hence\ total\ outcomes=20\\\\Blue\ marbles=12\\\\Hence\ favourable\ outcomes=12\\\\P(Blue)=\frac{12}{20}\\\\P(Blue)=\frac{2\times 6}{2\times 10}\\\\P(Blue)=\frac{6}{10}\\\\P(Blue)=0.60$

The Massachusetts Department of Employment and Training predicted that there will be 21% more jobs for computer programmers in M

vova2212 [387]

Answer:

19,324

Step-by-step explanation:

The original amount is 100% of the original amount since 100% means a whole amount.

A 21% increase means that the new amount will be 100% + 21% = 121% of the original amount.

Now we calculate 121% of 15,970.

To find a percent of a number, multiply the percent by the number. First, divide the percent by 100 to change it into a decimal.

121% of 15,970 =

= 121% * 15,970

= 1.21 * 15,970

= 19,323.7

19,324
