Hello :)
Answer: x=11
Measure angel BAD= 122
Explanation:
To find X you have to make an equation
10x-49=5x+6
And then you solve for x
To find the angel measure of BAD, you have to add bac and cab to get bad
Bac= 10(11)-49 which equals 61
Cab= 5(11)+6=61
61+61= 122
Which is the measure of BAD
I hope this helps and have a wonderful rest of your night

Answer:
All the conditions for the chi square test of homogeneity are satisfied.
Step-by-step explanation:
The conditions for the chi square test are
1) the sample is a random sample
2) the variable under study is categorical
3) all expected value of the number of sample observations are greater or equal to 5.
A)The observations must be independent
B) for 2 categories the expected values must be at least 5
C) for the 3 categories the expected values must be at least 1 and no more than 20% may be smaller than 5
The observations given are independent that is not equally likely i.e do not have equal chances of occurrences or are not dependent on each other.
4) the overall sample must be resonably large that is greater than 50
Number 3 because there is one output(y value) for one input (x value)
