Because there are 8 scraps total, and there are 3 pink scraps. The probability of pulling out a pink scrap is 3/8.
Answer:
46/55
Step-by-step explanation:
A B C Total
Male. 2 19 7 28
Female. 4 9 14 27
Total. 6 28 21 55
Total number of students = 55
Pr of picking a female = number of females / total number
= 27/55
There are 27 females and 28 people got a B
Number of females or those who got a B = 27 + 28 = 55
Subtract off 9 females who got B to help correct for double counting . We have 55 - 9 = 46
This means there are 46 people who either got a B, are females or are females who got a B
Pr(female or got a B) = number who are females or got a B / total number
= 46/55
The probability is 3/10 however I can’t see the answer choices. If you need an explanation let me know. Good luck
Answer:
x >5
Step-by-step explanation:
4(x - 3) - 2(x - 1) >0
Distribute
4x -12 -2x +2 > 0
Combine like terms
2x -10 >0
Add 10 to each side
2x-10+10 > 10
2x>10
Divide each side by 2
2x/2 > 10/2
x >5
Question:
Which three-dimensional figures have lateral faces that are polygons? check all that apply.
- cones
- cylinders
- hemispheres
- prisms
- pyramids
- spheres
Answer:
The correct choices are;
- prisms and
- pyramids
Step-by-step explanation:
A polygon is a figure closed or bounded with several straight line segments and polygons are named based on how many sides, side size and sizes of angles that they have present.
A three sided polygon for example is called a triangle
A lateral face are the faces of a prism except the base
Based on the definitions, we note that out of the options, only prisms, and pyramids have lateral faces that are made up entirely of straight line segments, hence polygons. Therefore, the correct choices are prisms and pyramids.
