Answer:
Now plot those points in graph and find intersection hope it helps you.......
I’ll check it give me a minute I’m mainly writing this so I know to come to this just sec
∠DBC = 19° since the two angles have to add up to 180, if x = 23, then 23 -4 = 19 for the right, and 7 x 23 = 161, and 161 + 19 = 180.
Answer:
Step-by-step explanation:

(One tailed test at 5% significance level)
Sample size =200 and sample proportion =
Std error of p = 
Test statistic = p diff/std error = -2.89
p value = 0.001926
So we reject H0 and accept alternate hypothesis.
Multiply (-5) and (7) together to get -35
Then multiply (6) and (-2) together to get -12
Finally multiply -35 and -12 together to get 420
So your answer to this is 420
Hope this helped :)
Have a good day
