The table below shows the total number of hours, Jessica, Emily, and Trina, each studied after given number of weeks. Part A one
of the relationships between weeks and total hours studied is proportional. Whose number of total hours studied is proportional to the number of weeks studied ? For the proportional relationship, write an equation to represent y, the total number of hours studied, in terms of x, the number of weeks. Explain how u determined your equation. Pls help

1.The isosceles triangle has sides of length 14, y, y
2. According to the "triangle inequality" :
y+y>14
2y>14
y>14/2=7
(y is greater than 7)
3. Remark, check the figures:
the side lengths cannot be less than (neither equal to 7), because we cannot get a triangle in that case, check picture 2
In picture 1 wee see that the side lengths can be as large as we want. We can erect an altitude, as high as we want. Pick a point on the altitude, and join it to the endpoints of the base, and we get an isosceles triangle with base equal to 14.

Answer:
The probability associated with the range lethal morphine blood levels is 0.9902.
Step-by-step explanation:
Let <em>X</em> = lethal blood concentration of morphine.
The random variable <em>X</em> is normally distributed with parameter <em>μ</em> = 2.5 μg/ mL and <em>σ</em> = 0.95 μg/ mL.
Compute the probability of <em>X</em> within the range 0.05 to 4.95 μg/ mL as follows:
*Use a <em>z</em>-table for the probability.
Thus, the probability associated with the range lethal morphine blood levels is 0.9902.
