Answer: 2.460
Step-by-step explanation:
The formula of Margin of Error for (n<30):-

Given : Sample size : n= 18
Level of confidence = 0.90
Significance level : 
Using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have

Hence, the margin of error (ME) of the confidence interval with a 90% confidence level = 2.460
Answer:
the answer would be 928
Step-by-step explanation:
you have 232 kit kats and if you put all of them in fourths you would multiply them by 4. 232 x 4= 928
Given:
A figure of triangles.
To find:
Whether the triangles SPT and triangle QPR are similar.
Solution:
In triangle SPT and triangle QPR,
(Given)
(Common angle)
In triangles SPT and triangle QPR, two corresponding angles are congruent. So, by AA property of similarity both triangles are similar.

Therefore, yes, the triangle SPT and triangle QPR similar. Option A is correct.
The correct answer is 8×(-6) - 8×3/4.
Simplifying this problem is the same as the problem 8× - 6 3/4, not 8× -5 1/4.
