The lifetimes of light bulbs of a particular type are normally distributed with a mean of 350 hours and a standard deviation of
musickatia [10]

Answer:

By the Empirical Rule, approximately 68% of the bulbs have lifetimes that lie within 1 standard deviation to either side of the mean.

Step-by-step explanation:

The Empirical Rule 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.

What percentage of the bulbs have lifetimes that lie within 1 standard deviation to either side of the mean?

By the Empirical Rule, approximately 68% of the bulbs have lifetimes that lie within 1 standard deviation to either side of the mean.

HELP NEEDED,THANK YOU find all real zeros and complex of each function f(x)=x(4x-6)(x+1)(3x+5).SHOW WORK!!!
lisov135 [29]

Answer:

x=0, 3/2, -1, -5/3

Step-by-step explanation:

The x-axis interception points of x(4x-6)(x+1)(3x+5): (0, 0), (3/2, 0), (-1, 0), (-5/3, 0)

The y-axis interception points of x(4x-6)(x+1)(3x+5): (0,0)

So the answer is 0, 3/2, -1, and -5/3.

A roller coaster climbs 120 feet from ground level then drops 75 feet before climbing another 105 feet. How far above ground is
Ostrovityanka [42]

Answer:

The roller coaster is 155 feet above the ground.

Step-by-step explanation:

Given:

The roller coaster climbs 120 feet from ground level.

Then drops 75 feet

Then again climbs 105 feet

To find distance of roller coaster above the ground now we will subtract the drop in level from the rise and then add the second rise to the difference.

This can be evaluated as:

125\ ft-75\ ft+105\ ft

⇒ 50\ ft + 105\ ft

⇒ 155\ ft

Thus the roller coaster is 155 feet above the ground.
