Answer:
The test statistic is -2.
Step-by-step explanation:
Test statistic (z) = (sample sd - population sd) ÷ sample sd/√n
sample sd = 0.025 inches
population sd = 0.035 inches
n = 25
z = (0.025 - 0.035) ÷ 0.025/√25 = -0.01 ÷ 0.005 = -2
B because you need to know if those angles are congruent
Multiply the percentage off by the original price: .35•120=42. Subtract that answer from the original price: 120-42=78. The new price is $78 :)
0.25 goes into 41 a total of 164 times. to get this answer you take 41 and divide it by 0.25 to get 164.
8 is greater than or equal to x
(where x = the number of tickets)
or x is less than or equal to 8
