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.

Step-by-step explanation:
You didn't write what to do with the fraction but I think you meant to ask to simplify it:
38b/-19
Multiply - 19 from top and bottom :
-2b
Answer:
The answer for the first picture is 84
The answer for the second picture is 36
Step-by-step explanation:
The first triangle is a isosceles triangle which means that two angle lengths must be the same. We use the only angle measurement which is 48 and subtract it from 180 twice because there are two angles lengths that are the same, once we subtract from 180 we have 84. The same process is followed for the second triangle.
180-48-48=84
Second Triangle:
180-72-72=36
