convert 0.5t5kg5hg to kilogram
Answer:
505.5kg
Step-by-step explanation:
To convert 0.5t5kg5hg to kilogram, first we need to convert 0.5t and 0.5hg to kg as shown;
1t = 1000kg
0.5t = 0.5 *1000
0.5t = 500kg
Similarly
1hg = 0.1kg
5hg = 5 * 0.1
5hg = 0.5kg
Adding up;
0.5t5kg5hg = 500kg+5kg+0.5kg
0.5t5kg5hg = 505.5kg
Hence the conversion to kg is 505.5kg

Let X and Y be independent Bernoulli random variables with parameters 0.2 and 0.3, respectively. Find the distribution of X Y. List all possible values that X Y can take. Write your answer as a comma-separated list ordered from smallest to largest value. possible values: List the probabilities that X Y takes each of the values. Write your answer as a comma-separated list giving the probabilities in the same order as in (a)
Answer:
a) 0 , 1
b) 0.56 , 0.06
Step-by-step explanation:
X = 0.2
Y = 0.3
Find the distribution of X + Y
a) All the possible values of X + Y
The possible values of X + Y are ; 0,1
b) The probabilities that X + Y takes each of the values
P(X+Y=0 ) = ( 1-0.2 )*(1-0.3) = 0.56
P( X +Y = 1) = 0.2*0.3 = 0.06

Evaluate 2.5(8.6/2)-1.8
Step-by-step explanation:
Given the expression:
[tex]2.5( \frac{8.6}{2} ) - 1.8[/tex]
Follow BODMAS rule.
always evaluate brackets first, followed by multiply or division then addition or subtraction from LEFT to RIGHT.
[tex]2.5( \frac{8.6}{2} ) - 1.8 \\ = 2.5(4.3) - 1.8 \\ = 10.75 - 1.8 \\ = 8.95[/tex]
hi guys what is and can u please do the method 4050 divided by 100
Answer:
40.5
Step-by-step explanation:
what i do is I divided first by 10. because 100 is 10x10.
so 4050 divided by 10 is 405.
405 divided by 10 is 40.5
4050 divided by 100 = 40.5

Given the figure below, find EF if CA = (6n) and EF = (n + 8)
Answer:
[tex]EF = 12[/tex]
Step-by-step explanation:
Given
[tex]CA =6n[/tex]
[tex]EF= n + 8[/tex]
Required
Find CN
From the attachment:
[tex]EF = CD\ and\ CD = DA[/tex]
Where
[tex]CA = CD + DA[/tex]
This means that:
[tex]CA = CD + CD[/tex]
[tex]CA = 2CD[/tex]
or
[tex]CA = 2*EF[/tex]
This gives:
[tex]6n = 2*(n+8)[/tex]
Open bracket
[tex]6n = 2n+16[/tex]
Collect anf simplify like terms
[tex]4n = 16[/tex]
[tex]n= 4[/tex]
So:
[tex]EF= n + 8[/tex]
[tex]EF = 4 + 8[/tex]
[tex]EF = 12[/tex]

Answer:
60
Step-by-step explanation:
I think that is the best choice sorry if i got it wrong.
Answer:
60 degrees
Step-by-step explanation:
Angle 1 is already 55 degrees, if you move the y line 5 degrees clockwise then it equals 60 degrees. Angle 1 and 3 are vertical angles so they are equal, if angle 1 is 60 degrees after we move the line then angle 3 is also 60 degrees

Researchers studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group.
(a) Identify the population of interest and the sample in this study.
(b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
A) Population of interest = children between the ages of 5 and 15
Sample = 160 children between the ages of 5 and 15.
B) Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.
Yes, the findings can be used to establish causal relationship because the study is just an experiment.
Step-by-step explanation:
A) Population of interest = children between the ages of 5 and 15
Sample = 160 children between the ages of 5 and 15.
B) Sample size is 160 which is above 30.
Thus, we can say;
Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.
Yes, the findings can be used to establish causal relationship because the study is just an experiment.
