Yes,it can be proved to be congruent,as:
AB=AD (given)
AC=AC (given)
Since AB = AD,it is an isosceles △
Thus,BC=CD(properties of isos.△)
Therefore,ΔCAB ≅ ΔDAC (SSS)
The answer is Yes;ΔCAB ≅ ΔDAC
Hope it helps!

Answer:
No. we cannot believe it as per hypothesis test done.
Step-by-step explanation:
Given that five hundred draws are made at random with replacement from a box of numbered tickets; 276 are positive.
To test the claim whether the proportion for positive numbers is 50% let us conduct a hypothesis test for proportions.
(Two tailed test at 5% significance level)
Sample proportion p =
Std error of p =
(assuming null hypothesis to be true)
Here P = 0.50
Test statistic = p difference/std error =
Z test is used for this proportion.
p value = 0.0198
Since p value <0.05 we reject null hypothesis
At 95% confidence level, there is statistical evidence to show that sample mean is not 50%
