Answer:

4.11

Step-by-step explanation:

7(p-9)=-34.3

first you want to apply what is outside of the parenthesis to the inside of the parenthesis. After applying you would get

7p-63=34.3

Next you wanna get the variable to one side and the whole numbers to the other side. to do this you add 63 to each side, you end up with

7p=28.8. Then you want to get p by itself. In order for this to happen you divide each side by 7 to get p=4.114285714

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 that $P(X$

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) = $P(Z>\frac{17-15}{1.356} \\=P(Z>1.475)\\=0.5-0.428\\=0.072$
