You were told that the amount of time lapsed between consecutive trades on the New York Stock Exchange followed a normal distrib
uysha [10]

Answer:

Step-by-step explanation:

Given that that (X) the amount of time lapsed between consecutive trades on the New York Stock Exchange followed a normal distribution with a mean of 15 seconds.

i.e. X is normal with mean = 15 and unknown std deviation \sigma

Given thatP(X

i.e. P(z

z=-1.475 (from normal table)

Hence \frac{13-15}{\sigma}=-1.475\\\sigma = 1.356

Using this we find P(X>17) = P(Z>\frac{17-15}{1.356} \\=P(Z>1.475)\\=0.5-0.428\\=0.072

which function has the greatest rate of change? A. y = 7/6x + 2/3 B. y = 7/5x + 7/5 C. y = 6/5x + 11/5 D. y = 5/4x + 15/4
ddd [48]

Answer:

Step-by-step explanation:

In y = mx + b form, the slope can be found in the m position

y = 7/6x + 2/3......slope(m) = 7/6 or 1.167

y = 7/5x + 7/5....slope(m) = 7/5 or 1.4

y = 6/5x + 11/5...slope(m) = 6/5 or 1.2

y = 5/4x + 15/4.....slope(m) = 5/4 or 1.25

so the greatest rate of change would be B. y = 7/5x + 7/5 with a slope of 7/5
