Answer:
Adding the 2 known angles: 60° + 100° = 160° We subtract this from 180°. 180° – 160° = 20°. Our missing angle is 20°. To find a missing angle in a triangle we subtract the two known angles from 180°.
Step-by-step explanation:
Answer:
1.703
Step-by-step explanation:
The reason we try to find t score is because the sample size is below 30, meaning the sample size is small
Hence:
Step 1
We find the degree of freedom
The Degrees of freedom = Number of samples - 1
The random number of samples = 28
= 28 - 1
= 27
Step 2
Using a t score table or t score calculator, we can obtain the t score value for a 90% confidence interval and degree of freedom of 27
90% confidence interval =
10% significance level = 0.10 for two tails or 0.1/2 = 0.05 for one tail
Hence: t90 = 1.703
1 yard = 3 feet
7 yard = 21 feet
21 + 2 = 23 feet
