Answer:
The correct answer is (C) or .227. The number of natural blackjacks (X) follows a binomial distribution with n=20, p=0.045.
Explanation:
P(X≥2)=1−P(X≤1)=1−0.773=0.227.
Answer: A. Paris is an old city, but some is even more ancient.
Explanation:
A is a compound sentence because the there are two complete sentences in the sentence. “Paris is an old city” is a complete sentence. “Some is even more ancient” is another full sentence. If there are two or more complete sentence separated by a conjunction, then It is a compound sentence. B is not a compound sentence, because there is only one complete sentence.
Answer:
21feet = h
The height of the pyramid is 21 feet
Explanation:
Like the volume of any pyramid and any tetrahedron, the volume is the area of the base by the height and divided by three.
a and b are the sides of the base, which is a rectangle, and therefore a*b is the area of the base.
Volume= a*b*h/3
1) The term we need to know is the h which is the height. What we are going to do is to leave alone the h in one side of the equation applying math properties.
3*V= a*b*h
What we did was to bring the 3 to the other side. It was dividing on the right side of the equiation. To go to the other side, it must multiply the term on the left.
2) Now, we need to bring the a*b to the left side. We take the term and pass it dividing the term on the left.
(3*V )/ (a*b) = h
3) Now we can use the equation to find the height.
(3*525f³) / (15f*5f) = h
21f = h
From the perspective of enslaved African Americans, slavery ended before the passage of the 13th Amendment because of the Emancipation Proclamation. It is important to note that the Emancipation Proclamation did not officially end slavery, but it did provide the impetus for subsequent legislation. The Emancipation Proclamation took effect on January 1, 1863 and granted freedom to all enslaved persons in states that were in rebellion against the Union. It also inspired enslaved African Americans to leave Southern plantations in large numbers and flee toward Union lines. Union troops were forced to make provisions for these enslaved people within their ranks.
President Lincoln would argue that the Emancipation Proclamation was simply a strategic move designed to destabilize the southern states. It did not apply to border states and it was null and void if the rebellious state returned to the Union. Moreover, because the southern states had seceded, they were no longer under the authority of the federal government, thus Lincoln had no authority over them
Enslaved people played an important role in the war as soldiers (those who escaped) and as laborers in the South for the Confederacy. They served as spies for the North.
