Answer:
Gradient is change in y over change in x.
gradient = y1-y2 ÷ x1-x2
=7-11 ÷ 3-5
=-4 ÷ -2
=2
Answer:
i believe the 3rd one is it but yet im not for sure
Step-by-step explanation:
Factors of 121 are; 1,11, and 121. so it would be D.
Since the time to failure distribution is
exponential, the distribution is F (n) = 1 – e ^ (-x/48)
The probability of failure between months 60
and 72 is the same as the probability that the battery will fail in 12 months,
since the exponential distribution is memoryless F (12) = 0.221

solve for "w", to find the wind's speed rate,
so hmmm what's the plane's rate? well 420 - w = r :)
