Answer:

-20x / (x-12) = y

Step-by-step explanation:

3/x - 5/y = 1/4

Multiply each side by 4xy to clear the fractions

4xy ( 3/x - 5/y = 1/4)

Distribute

12y - 20x = xy

Subtract 12y from each side

-20x = xy -12y

Factor out y

-20x = y(x-12)

Divide each side by (x-12)

-20x / (x-12) = y

Vlad [161]

Answer: 0.4758

Step-by-step explanation:

Given : Mean : $\mu=137\text{ lb}$

Standard deviation : $\sigma =28.9\text{ lb}$

Also, the new population of pilots has normally distributed .

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\sigma}$

For x=130 lb .

$z=\dfrac{130-137}{28.9}=-0.2422145\approx-0.24$

For x=171lb.

$z=\dfrac{171-137}{28.9}=1.1764705\approx1.18$

The p-value = $P(-0.24$

$=0.8809999-0.4051651=0.4758348\approx0.4758348\approx0.4758$

Hence, the required probability : 0.4758

Answer:

73 - 2x = 86 - 3x

So 3x - 2x =86 - 73 so x=13

Step-by-step explanation:

Then m<1 = 73-2(13) = 47

M<2=82-3(13)=47

So both angles are having same value
