Let gradient of original line = m = 1/6
Gradient of line perpendicular to this = -1/m = -6
(Gradient = slope)
Answer:
the answer is 5
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
(10 - x ) / x = 3/2 Cross Multiply
2*(10 - x) = 3x Remove the brackets
20 - 2x = 3x Add 2x to both sides
20 = 3x + 2x
5x = 20 Divide both sides by 5
x = 20/5
x = 4
Answer:
b. 2.28%.
Step-by-step explanation:
Mean temperatue (μ) = 1000°F
Standard Deviation (σ) = 50
°F
For any temperature value, X, the z-score is given by:
For X= 900°F
A z-score of -2.0 corresponds to the 2.28-th percentile of a normal distribution. Therefore, the probability that X<900 is:
