Answer: The confidence interval would be (0.2928,0.3672).
Step-by-step explanation:
Since we have given that
Total number of vehicles = 432
Number of SUVs sold = 142
So, it becomes,
At 90% confidence interval,
z = 1.645
So, the confidence interval would be
Hence, the confidence interval would be (0.2928,0.3672).
The answer is orange because I think that is the answer

Answer:
x = 71/5 (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)
Step-by-step explanation:
It's a rectangle so the diagonals are equal
7x - 9 = 2x + 62
Subtract 2x from both sides
5x - 9 = 62
Add 9 to both sides
5x = 71
Divide both sides by 5
x = 71/5 (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)
Answer:
The answer is 144.
Step-by-step explanation:
Cause, 6 x 6 for the square is 36. For the triangle, 9 x 6 is 54, and 54 divided by 2 is 27. 27 x 4 is equal to 108. Now, we just add 108 and 36 to make 144.
