x = 37.5 (or)
Solution:
Given
AC = 50, DE = 30, EC = 25, BE = x, BC = 25 + x
To find the value of x:
Property of similar triangles:
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.
Do cross multiplication, we get
Subtract 30x from both sides of the equation.
Divide by 20 on both sides of the equation, we get
x = 37.5 (or)
Hence the value of x is 37.5 or .
Answer: a. 0.1031; fail to reject the null hypothesis
Step-by-step explanation:
Given: Significance level :
The test statistic in a two-tailed test is z = -1.63.
The P-value for two-tailed test : [By p-value table]
Since, 0.1031 > 0.05
i.e. p-value >
So, we fail to reject the null hypothesis. [When p< then we reject null hypothesis ]
So, the correct option is a. 0.1031; fail to reject the null hypothesis.
