First convert all of the fractions into the same denominator. 1/3 = 2/6. Add the new fraction of history books and the fraction for english books. 2/6 + 1/6 = 3/6. Subtract the total from 1 or 6/6. 6/6 - 3/6 = 3/6. The answer is 3/6 or 1/2 when reduced. 50% or 1/2 of the books are science books.
Answer:
The probability that the system is a Wii console is 0.46
Step-by-step explanation:
Probability expresses the possibility of an occurrence of an event. The probable outcomes for the event is called sample space.
For the given question,
Number of Sony Playstations = 6
Number of Nintendo Wii consoles = 5
Total number of games on the shelve = 11
Probability that the game selected is Wii console implies the possibility of picking one out of the 5 consoles.
pr(the system is a Wii console) = 
= 0.4555
≅ 0.46
The probability that the system is a Wii console is 0.46.
Um I assume you're wanting the circumferences of the fences so we have 3 that are all the same size and one that is 3 times as large as any of the others
so here's our equations
3x+y=113.04
y=3x
use substitution
3x+3x=113.04
6x= 113.04
now the question says use 3.14 so I'm thinking you want the answer in terms of pi so first divide 113.04 by 3.14
6x=36pi
x=6pi now substitute that back in for x in one of your equations
y=(3)(6pi)
y=18pi
so the tomatoes carrots and cabbage will all have a circumference of 6pi and the strawberries 18pi
Answer:
i) Assigning women at random ensures that the two groups are comparable.
iv) A control group provides a baseline for comparisons to determine treatment effects.
Step-by-step explanation:
(a)
It is pertinent that there two comparable groups. In light of the fact that it will help in making better decisions since there will be some people who have blood pressure as a result of uncontrolled physical characteristics such as anger, positive attitude, lower blood pressure. etc Thus, there is a need to consider two equivalent groups.
(b)
A control group is used as a benchmark for determining the cause and effect of a treatment on a given experimental group. This may be in regard to the social aspect of meeting other individuals involved that make up the physical changes.
