Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a standard deviation of 1500 hours
FromTheMoon [43]

Answer:

0.2776

Explanation:

Mean = 15000, SD = 1500

We need to find Cumulative probability: P(X > 15884)

First we need to convert it into normal distribution.

From the attached file, we can see the shaded area we are looking for.

For conversion as follow; P (X>15884) =P ( X - mean > 15884-15000 ) =P (\frac{X- mean}{SD} > \frac{15884-15000}{1500} )

Next to find Z = \frac{X- mean}{SD} = 0.59

now we have converted to normal distribution and found the value of Z, we need to find the probability P(X > 15884).

P(X > 15884) = P(Z > 0.59).

From the normal distribution table at Z= 0.59, and greater than 0.59, Probability = 0.2776.

PLS I REALLY NEED HELP
Juli2301 [7.4K]

Answer:

Because only the House can originate tax bills, and both chambers are needed to approve

Explanation:

Because before Congress can raise taxes, the president must ask them to do so - Wrong, Congress dose not need the president permission to vote on something

Because he was preparing them to accept tax increases he planned to impose as president - Wrong, the President dose not need prepare congress for anything. Congress has the power under the U.S Constution to handle changeing and creating new laws.

Because without Congress voting to raise taxes, it would have been impossible to get the loans - Wrong, because the states individual could choose to raise taxes for their own states.

Therofre, I will go with

Because only the House can originate tax bills, and both chambers are needed to approve
