3 points) Fluorescent lighbulbs have lifetimes that are normally distributed with a mean of 6.6 years and a standard deviation of 1.3 years. The figure below shows the distribution of lifetimes of fluorescent lightbulbs. Calculate the shaded area under the curve. Express your answer in decimal form with at least two decimal place accuracy.

Answers

Answer 1

The shaded area under the curve is 0.597723.

We are to calculate the shaded area under the graph curve.

Information Given

Mean = 6.6

Standard deviation = 1.3

X ⇔ N (μ=6.6, σ=1.3)

= P [5.229 < X < 7.4]\

= P {{5.229-6.6} / 1.3} < Z < [{7.4-6.6}/1.3}]

= P {-0.857 <Z < 0.615}

=P[Z≤0.615} - P[Z≤-0.867}

We are using the normal probability table.

= 0.730723 - 0.133

= 0.597723

Therefore, the shaded area under the curve is 0.597723.

Did the concept of liberty and equality change in the United States in the 1960s?

Answers

Answer:

read below to find the answer

Explanation:

The civil rights movement was a struggle for social justice that took place mainly during the 1950s and 1960s for Black Americans to gain equal rights under the law in the United States. The Civil War had officially abolished slavery, but it didn’t end discrimination against Black people—they continued to endure the devastating effects of racism, especially in the South. By the mid-20th century, Black Americans had had more than enough of prejudice and violence against them. They, along with many white Americans, mobilized and began an unprecedented fight for equality that spanned two decades.

Answer:

Yes

Explanation:

The 1960s were a time of enormous change in the boundries of American individualism. The civil rights revolution was a belated recognition that black Americans had been effectively barred from the ranks of individuals whom Jefferson had said two centuries earlier possessed ``unalianable right" to ``Life, Liberty and the pursuit of Happiness."
