Answer:

X1=0+40/8=5(A)

X2=0-40/8=-5(B)

RTA= 5 and -5 are the roots of the equation

Step-by-step explanation:

F(x)=4X^2-100=0

You do BHASKARA in order to get the roots(or zeros)

0(√0-4·4·-100)/2·4=

X1=0+40/8=5(A)

X2=0-40/8=-5(B)

Suppose the commute times for employees of a large company follow a
Anna [14]

Using the Empirical Rule, it is found that 95% of the employees will have a travel time within the following range:

B. 8 minutes to 28 minutes.

<h3>What does the Empirical Rule state?</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.

Considering that the mean time is 18 minutes and the standard deviation is 5 minutes, the the bounds of the 95% range are given by:

  • 18 - 2 x 5 = 8 minutes.
  • 18 + 2 x 5 = 28 minutes.

Hence option B is correct.
