Answer:

Part A.) 0.3 or 30%

Part B.) 0.5 or 50%

Step-by-step explanation:

She flipped the coin 30 times.

She flipped it 9 times for heads.

She flipped it 21 times for tails.

Part A.)

9/30

When you simplify that you get 3/10.

Which is 0.3 or a 30%

Part B.)

So there are only 2 sides of a coin.

Heads or tails, So its a 50 - 50

Hence

For One side it is 50/100

Which simplifies to 1/2

Or 0.5 which is 50%

Find the slope of the lines. Are the 2 lines parallel or perpendicular? Explain how you can use the slope of two lines to tell i
rewona [7]

Answer:

slope = \frac{3}{7} and - \frac{7}{3}, perpendicular

Step-by-step explanation:

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = \frac{3}{7} x + 11 is in this form with m = \frac{3}{7}

Rearrange 7x + 3y = 13 into this form

subtract 7x from both sides

3y = - 7x + 13 ( divide all terms by 3 )

y = - \frac{7}{3} x + \frac{13}{3} ← in slope- intercept form

with m = - \frac{7}{3}

• Parallel lines have equal slopes

• The product of perpendicular slopes = - 1

The lines are not parallel since slopes are not equal

\frac{3}{7} × - \frac{7}{3} = - 1

Hence lines are perpendicular
