Conner played a total of  6 +3 + 6 = 15 games. He won or tied 6+ 3 = 9 games.

His percentage is 9/15 = 0.6 x 100 = 60%

April played 5+7+4 = 16 games and won or tied 5 +7 = 12 games.

Her percentage is: 12/16 = 0.75 x 100 = 75%

Tony played 20 games and won or tied 14.

His percentage is: 14/20 = 0.7 x 100 = 70%

April has the highest percentage so she is the one who should play.

F(x) = -3(x+4)(x-6) x intercepts
DiKsa [7]

Answer:

x = - 4, x = 6

Step-by-step explanation:

To find the x- intercepts let y = 0 , that is

- 3(x + 4)(x - 6) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 6 = 0 ⇒ x = 6

A sample of computer tablet batteries has a mean battery life of 28 months and standard deviation of 4 months. What is the lifes
Ulleksa [173]

Using the Empirical Rule, it is found that the lifespans, in months, are given by:

1. 24 and 32.

2. 20 and 36.

3. 16 and 40.

<h3>What is the Empirical Rule?</h3>

It states that, for a normally distributed random variable:

  • Approximately 68% of the measures are within 1 standard deviation of the mean.
  • Approximately 95% of the measures are within 2 standard deviations of  the mean.
  • Approximately 99.7% of the measures are within 3 standard deviations of the mean.

Hence, considering the mean of 28 months and the standard deviation of 4 months, the life spans are given by:

1. 24 and 32.

2. 20 and 36.

3. 16 and 40.
