BC <span>≅ EF (CPCTC)
Set the two side lengths equal to each other.
38.4 = 5x - 10.6
Isolate the x. Add 10.6 to both sides
38.4 (+10.6) = 5x - 10.6 (+10.6)
5x = 49
Isolate the x, divide 5 from both sides
5x/5 = 49/5
x = 49/5
x = 9.8
9.8 should be your answer

Answer:
Proportions have not changed significantly ( B )
Step-by-step explanation:
GIVEN DATA :
Test statistic = 4.99
significance level = 1% = 0.01
k ( number of groups ) = 3
will we use the chi-squared test to determine the degree of freedom
which is : k-1 = 3 - 1 = 2
looking at the chi-square table to determine the critical value of the test
at significance level = 0.01 and degree of freedom = 2 the critical value = 9.21
Comparing the test value ( 4.99 ) and the critical value ( 9.21 ) it can seen that the test value < critical value which is a condition for not rejecting null hypothesis of the test.
therefore we won't reject the null hypothesis
