Solve: 2/3 x - 4 = -2 A) -3 B) -4 C) -9 D) 3
Mumz [18]

Answer: x = 3

Step-by-step explanation: First, isolate the x term by adding 4 to

both sides of the equation. We get 2/3x = 2.

Next, multiply both sides of the equation by the

reciprocal of 2/3 which is 3/2 to get x by itself.

So we have (3/2) 2/3x = 2 (3/2).

On the left, (3/2) 2/3 cancels and we have x.

On the right, the 2's cancel and we have 3.

So x = 3 is our answer.

A softball pitcher has a 0.507 probability of throwing a strike for each pitch. If the softball pitcher throws 15 pitches, what
Elena L [17]

Answer:

The probability that the pitcher throws exactly 8 strikes out of 15 pitches is approximately 0.199

Step-by-step explanation:

The given probability that the pitcher throws a strike, p = 0.507

The number of pitches thrown by the pitcher = 15 pitches

The probability that the pitcher does not throw a strike, q = 1 - P

∴  q = 1 - 0.507 = 0.493

By binomial theorem, we have;

P(X = r) = \dbinom{n}{r}p^{r} \cdot q^{n-r}=  \dbinom{n}{r}p^{r} \cdot \left (1-p  \right )^{n-r}

When X = r =  8, and n = 15, we get;

The probability that the pitcher throws exactly 8 strikes out of 15 pitches, P(8), is given as follows

P(8) = ₁₅C₈ × 0.507⁸ × (1 - 0.507)⁽¹⁵ ⁻ ⁸⁾ = 6,435 × 0.507⁸ × 0.493⁷ ≈ 0.199
