Hello there! How to find the probability? See picture! Thank you and please show your work!

Answer:

0.8914

Step-by-step explanation:

You want to find the z-values associated with the x-values:

z = (x -μ)/σ

z1 = (57 -90)/12 = -2.75

z2 = (105 -90)/12 = 1.25

Look up these values in a probability table and find the difference of the table values.

p(z < z1) ≈ 0.00298 . . . . from a table or calculator

p(z < z2) ≈ 0.89435 . . . . from a table or calculator

p(57 < x < 105) ≈ 0.89435 -0.00298 = 0.89137 ≈ 0.8914

Sophie would’ve earned more
She would’ve earned $37 more

Calculations:
Sophie:
$330(1+4%*2)
=$356
Simple interest: $356-$330
=$26

Avi:
$290(1+5%*2)
=$319
Simply interest: $319-$290
=$29

$29-$26
=$3

To attempt to end slavery is what I would think, maybe to show that they are humans themselves and treating them this way is very unfair.

Am I correct on question #6?

pashok25 [27]

Option A:

$\tan(105^\circ)=-(2+\sqrt{3})$

Solution:

<u>To evaluate tan(105)°:</u>

105° can be written as sum of 60° and 45°.

tan(105)° = tan(45 + 60)°

Using the summation identity:

$$\tan (x+y)=\frac{\tan (x)+\tan (y)}{1-\tan (x) \tan (y)}$

$$\tan \left(105^{\circ}\right)=\frac{\tan \left(45^{\circ}\right)+\tan \left(60^{\circ}\right)}{1-\tan \left(45^{\circ}\right) \tan \left(60^{\circ}\right)}$
