Answer:
Below in bold,
Step-by-step explanation:
a. There's is only one card that fits this description so
Probability = 1/52.
b. There are 2 black Kings so
Probability = 2/52 = 1/26.
c. There are 2 of these - 7 of diamonds and 7 of hearts
so
Probability = 2/52 = 1/26.
d. There 13 diamonds and 13 hearts so
Probability = 26/52 = 1/2.
e. There 26 black cards
Probability = 26/52 = 1/2.
Answer:
Yes.

There were 45 markers originally in each box.
Step-by-step explanation:
Given,
Boxes ordered = 3 large boxes
Markers given to one teacher = 15
Markers given to 3 teachers = 15*3 = 45 markers
Remaining markers = 90
Let,
x be the original number of markers in 3 boxes.
Total markers - markers given to teachers = markers left
![x-45=90\\x=90+45\\x=135](https://tex.z-dn.net/?f=x-45%3D90%5C%5Cx%3D90%2B45%5C%5Cx%3D135)
There were 135 markers in 3 boxes.
3 boxes = 135 markers
1 box = ![\frac{135}{3}=45\ markers](https://tex.z-dn.net/?f=%5Cfrac%7B135%7D%7B3%7D%3D45%5C%20markers)
There were 45 markers originally in each box.

Answer:B
Step-by-step explanation: When solving expressions with parentheses it’s important to always solve what’s in parentheses first. And when there’s parentheses in parentheses, solve the parentheses that are in the parenthesis. Whew...I hope this helps :)
216 raised to the power 1/3 can also be written as cube root of 216.
Changing the given expression to radical form, we can write:
![(216)^{ \frac{1}{3} } \\ \\ = \sqrt[3]{216}](https://tex.z-dn.net/?f=%28216%29%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%20%5C%5C%20%20%5C%5C%20%0A%3D%20%5Csqrt%5B3%5D%7B216%7D%20)
216 is the cube of 6 i.e. multiply 6 three times (6 x 6 x 6), you will get 216.
So we can write the above expression as:
![\sqrt[3]{(6)^{3} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%286%29%5E%7B3%7D%20%7D%20)
The cube root and cube cancel out each other, leaving the answer equal to 6.
So, the correct answer is option B
