Answer:
Option b
Step-by-step explanation:
Given that the probability distribution of X, where X is the number of job applications completed by a college senior through the school’s career center.
Expected observed Diff
x p(x) p(x)*1000
0 0.002 2
1 0.011 11 14 -3
2 0.115 115 15 100
3 0.123 123 130 -7
4 0.144 144
5 0.189 189
6 0.238 238
7 0.178 178
1 1000
We find that there is a large difference in 2 job application
Hence option b is right.
The probability that both the chosen students are sophomores is 6/20 or 3/10 simplified.
the expresión that represents the probability that both students have chosen are sophomore is (6c1) (5c1) /(20c2)
The diagram included should explain this.
<span> Nina + her 5 friends = 6 people
Then she has 9 apple to share with her and her friends.
Let’s calculate how many apple will each people get when they equally divide it
with each other:
=> 9 – 6 = 3
Thus already have 1 apple each, now, let’s divide the remaining 3 apples
=> 3 / 6 = .5
So they have half of apple each. Let’s add
=> 1 + .5 = 1.5
Each person will get 1.5 apple.
=> 1.5 * 6 = 9</span>
Answer:
The dimensions of the rectangular prism is 5 inches by 7 inches by 8 inches. Volume of the rectangular prism is expressed as
Length of the base × width of the base × height of the prism.
Volume = 5×7×8 = 280 inches ^2
Each golf ball has the shape of a sphere. The volume of a sphere is expressed as
Volume of sphere = 4/3πr^3
The golf ball has a diameter of 1.7 inches. It means that the radius of the golf ball is 1.7/2 = 0.85
Volume of each golf ball = 4/3 × 3.14×0.85^3
= 2.57 inches^3
The number of golf balls that will fit into the compartment would be
Volume if compartment/ volume of each golf ball. It becomes
280/2.57 = 109 golf balls
