380.25 is the answer because 78÷4=19.5 then you multiply 19.5×19.5=380.25

- The spinner shown is spun 4 times. What is the probability that you will spin gray at least 2 times?

lisov135 [29]

Answer:

26.17%

Step-by-step explanation:

P(Grey) = 1/4

P(Grey at least 2 times in 4) = 1 - P(no Grey in 4) - P(1 Grey in 4)

P(no Grey in 4) = 4C0 * 3/4 * 3/4 * 3/4 * 3/4 = 81/256

P(1 Grey in 4) = 4C1 * 1/4 * 3/4 * 3/4 * 3/4 = 27/64

P(Grey at least 2 times in 4) = 1 - 81/256 - 27/64 = (256-81-108)/256=67/256=26.17%

WILL GIVE BRAINLIEST!! Which equations are correct? Select each correct answer.

solong [7]

To multiply these expression, multiply the numeric parts, and sum the exponents of the literal parts (because the variable is the same: we're using the power property $a^b\cdot a^c = a^{b+c}$ ).

So, you have:

$3z^7 \cdot (4z^2) = 3\cdot 4 \cdot z^{7+2} = 12z^9$
$6a^5 \cdot (6a^5) = 6\cdot 6 \cdot z^{5+5} = 36z^{10}$
$6b^4 \cdot (-3b^4) = 6\cdot (-3) \cdot b^{4+4} = -18b^8$
$5x^4 \cdot (4x^2) = 5\cdot 4 \cdot x^{4+2} = 20x^6$
