Question

39 multiple choice 2 points the four faces of a fair tetrahedron die are numbered 1, 2, 3, and 4. in two tosses the die, the probability of obtaining exactly two 4s is 40 multiple choice 2 points what is the value of n in the equation 3n - 8 = 32 - n? -10 10 6 -6 41 multiple choice 2 points what is 507,000 in scientific notation? 507 × 10³ 0.507 × 10⁶ 50.7 × 10⁴ 5.07 × 10⁵

Explanation:

Step1: Solve the equation \(3n - 8=32 - n\)

Add \(n\) to both sides: \(3n + n-8=32 - n + n\), so \(4n-8 = 32\).

Step2: Isolate the term with \(n\)

Add \(8\) to both sides: \(4n-8 + 8=32 + 8\), so \(4n=40\).

Step3: Solve for \(n\)

Divide both sides by \(4\): \(n=\frac{40}{4}=10\).

Answer:

10
