Answer:

\frac{128}{2187}

Step-by-step explanation:

Using the rule of exponents

a^{m} × a^{n} = a^{(m+n)}

(\frac{2}{3}) ^{3} × (\frac{2}{3}) ^{4}

= (\frac{2}{3}) ^{(3+4)}

= (\frac{2}{3}) ^{7}

= \frac{2^{7} }{3^{7} }

= \frac{128}{2187}

Greg has four different colored cards in a box. Yellow, red, blue, and green. He randomly selects one card, records the color, a
Veronika [31]

Answer:

He should expect to select 75 yellow cards.

Step-by-step explanation:

Since there is replacement, for each trial, we have:

1 yellow card

1 red card

1 blue card

1 green card.

If Greg does this 300 times, how many yellow cards should he expect to select?

Each trial, there are 4 cards, one of which is yellow. So 1/4 = 0.25 probability of selecting a yellow card.

Over 300 trials

0.25*300 = 75

He should expect to select 75 yellow cards.

A, B & C lie on a straight line.
Liono4ka [1.6K]

Answer:

x = 129°

Step-by-step explanation:

∠ ABD and ∠ DBC are a linear pair and sum to 180° , then

y + ∠ DBC = 180°

107° + ∠ DBC = 180° ( subtract 107° from both sides )

∠ DBC = 73°

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles , then

x = ∠ DBC + z = 73° + 56° = 129°
