X=6 because in the first one it says that 10 times X plus the 30 equals the 90 degree angle so that means that X=6 because 10 times 6 is 60 pulse the extra 30 degrees.
Answer:
Option (a) 45.31
Step-by-step explanation:
Data provided in the question:
Standard deviation, σ = 0.08 mm
Sample size, n = 30
standard deviation of 30 samples, s = 0.10
Now,
σ² = (0.08)² = 0.0064
s² = (0.10)² = 0.01
Test Statistic = [ ( n - 1) × s²] ÷ σ²
or
Test Statistic = [ (30 - 1 ) × 0.01 ] ÷ 0.0064
= ( 29 × 0.01 ) ÷ 0.0064
= 45.31
Hence,
Option (a) 45.31
Answer:
Y= 1/3x-15
Step-by-step explanation:
-6=-3(-3)+b
-6= 9+b
subtract 9 on both sides
b= -15
Y= 1/3x-15
because its perpendicular the -3x become positive and reciprocal
Answer:
slope intercept form: y = mx + b
6x - 4y = 24
4y = 6x - 24
y = 3/2x - 6
slope: <u>3/2</u>
y intercept: <u>- 6</u>
