Answer:

r=\frac{4}{63}

Step-by-step explanation:

1) Divide both sides by the same factor

9r=\frac{4}{7}

\frac{9r}{9} =\frac{\frac{4}{7} }{9}

2) Simplify

  • Cancel terms that are in both the numerator and denominator

\frac{9r}{9} =\frac{\frac{4}{7} }{9}

r=\frac{\frac{4}{7} }{9}

  • Divide the numbers

r=\frac{\frac{4}{7} }{9}

r=\frac{4}{63}

Afina-wow [57]

Answer: −1.409

Step-by-step explanation:

Probability of drawing 3 hearts: 13/52 * 12/51 * 11/50 = 0.013

Probability of drawing 3 black cards: 26/52 * 25/51 * 24/50 = 0.118

Probability of other draw: 1 - 0.013 - 0.118 = 0.869

0.013 * (50 - 5) = 0.585

0.118 * (25 - 5) = 2.353

0.869 * (0 - 5) = -4.347

Expected value: 0.585+ 2.353 - 4.347 = -1.409

Given the parent function
lozanna [386]

Answer:

Option c is right.

Step-by-step explanation:

Given is a parabola y =x^2

From that transformation is done to get parabola as

y =(0.2x)^2

We find that instead of x here we use 0.2x

i.e. New x = 5 times old x

Hence there is a horizontal expansion of scale factor 5.

We can check with any point also

When y =4, x=2 in the parent graph

But when y =4 , we have x = 10 in the new graph

i.e. there is a horizontal expansion of scale factor 5.
