Answer:
1/16
Step-by-step explanation:
The probability of getting a blue marble is : [tex]\frac{3}{5+3+2+2} = \frac{1}{4}[/tex]
As the marble is replaced in the box, the probability of getting a blue marble on the second round is [tex]\frac{1}{4}[/tex] too.
When you have mutliple events which are following themselves, you should multiply the probabilities of each event:
[tex]\frac{1}{4} X \frac{1}{4} = \frac{1}{4X4} = \frac{1}{16}[/tex]

The answer is a and b.
Here's the way to check:
Since all the numbers follow a constant sequence, it is possible to use division. Minus the first term, then divide it by the pattern of the sequence.
For a, 512 - 8 = 504
The pattern from a is each number is increased by 7. So,
504 ÷ 7 = 72
The number itself you count is not important. The point is that the number could be divided fully without remainder. This means 512 will appear in the sequence.
Repeat the above steps for b and c:
512 - 23 = 489
489 ÷ 3 = 163
It can be divided without remainder, 512 appears in this sequence.
512 - 12 = 500
500 ÷ 12 = 41.66666
Since C is a decimal ( there is remainder ), the number 512 does NOT appear in the sequence.
However, if you want to know the logic of WHY this works, I won't be able to give you a satisfying answer. Hope this helps you.

Step-by-step explanation:
Hello!
Height of pyramid = 845 feet
Slant height = 856 feet
width = 175 feet
The surface area of a pyramid = The base area of the pyramid added to the area of the 4 triangles.
The volume of a pyramid = 1/3 base area * height
1 Triangle = 1/2 base * height
Triangle = 1/2 * 175 * 856 feet
1 Triangle Area = 74,900 feet
The area of 4 triangles = 299,600 feet
Now, the area of the base = is 175 * 175 feet
Base area = 30,625 feet
Surface area = 30,625 + 299,600 feet = 330,225 feet
Volume = 1/3 * Base area * height of pyramid
Volume = 1/3 * 30,625 feet squared * 845 feet
Volume = 1/3 * 25,878,125 feet cubed
Volume = 8,626,041.(6) feet cubed

Answers
Answer:
you have four walls. two of them 12*8 and the other two are 10*8 ( we used 8 in both because it's the height of the room). so it goes( 2*12*8)+(2*10*8) and it goes 352S
Step-by-step explanation:
let's say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper.
for walls A= 2*12*8=192
for walls B=2*10*12=160
in total, you need 160+192= 352 square feet of wallpaper

Answers
Answer: The shorter side is 2 units, and the longer side is 12 units.
Step-by-step explanation: The original square is 5 units. multiply by decimal equivalents to find the new scaled units
40% of 5 is 2 That is: 0.4 × 5 = 2.0
