Step-by-step explanation:
I guess you do not need an explanation, so I gave you only an answer.
Answer:
6
Step-by-step explanation:
10/5 ×/3 multiply 10×3 and than divide by 5
or another way start with multiplying 5 and n equaling 5n=
than 10× 3= 30 so you're left with 5n=30 divied 30 by 5 equalling 6
so x=6
Complete question :
Birth Month Frequency
January-March 67
April-June 56
July-September 30
October-December 37
Answer:
Yes, There is significant evidence to conclude that hockey players' birthdates are not uniformly distributed throughout the year.
Step-by-step explanation:
Observed value, O
Mean value, E
The test statistic :
χ² = (O - E)² / E
E = Σx / n = (67+56+30+37)/4 = 47.5
χ² = ((67-47.5)^2 /47.5) + ((56-47.5)^2 /47.5) + ((30-47.5)^2/47.5) + ((37-47.5)^2/47.5) = 18.295
Degree of freedom = (Number of categories - 1) = 4 - 1 = 3
Using the Pvalue from Chisquare calculator :
χ² (18.295 ; df = 3) = 0.00038
Since the obtained Pvalue is so small ;
P < α ; We reject H0 and conclude that there is significant evidence to suggest that hockey players' birthdates are not uniformly distributed throughout the year.
b must be equal to -6 for infinitely many solutions for system of equations and
<u>Solution:
</u>
Need to calculate value of b so that given system of equations have an infinite number of solutions
Let us bring the equations in same form for sake of simplicity in comparison
Now we have two equations
Let us first see what is requirement for system of equations have an infinite number of solutions
If and are two equation
then the given system of equation has no infinitely many solutions.
In our case,
As for infinitely many solutions
Hence b must be equal to -6 for infinitely many solutions for system of equations and
