4 (a+3)=36 show all steps

PtichkaEL [24]

$4(a+3)=36$
Delete the parentheses, multiplying with the number of outside, making the set of signals
$4a + 12 = 36$

Number with incognito are to the left of the equality and numbers without incognito are to the right, remembering that when changing of side changes the signal.

$4a = 36 - 12$
$4a = 24$
$a = \frac{24}{4}$
$\boxed{a = 6}$

Confirm that the solution is correct:
$4(a+3)=36$
$4(6+3)=36$
$4(9)=36$
$36=36$ (TRUE)

Answer:
$\boxed{a = 6}$

The number of trials = 10
Probability of success (getting a 3) is p = 1/6
Probability of failure (not getting a 3) is q = 1 - 1/6 = 5/6

The probability of one success after 10 trials is given by the binomial distribution as
₁₀C₁ p¹ q⁽¹⁰⁻¹⁾ = 10*(1/6)*(5/6)⁹ = 0.323

Answer: 0.323
