My friend... My method wasn't wrong and I couldn't find any mistake on my procedure... Check it out and analyze it by yourself...
Answer:
73.6
61.824
.2776
2.3
1.342
.4129
*note* I had trouble reading the standard deviation of the second part, so if it's not 3 then leave a comment and i will fix it*
Step-by-step explanation:
1.)
the mean would be something like 460*.16= 73.6
The variance should be 460*.16(1-.16)= 61.824 which means the standard deviation is √61.824= 7.863
for p to be less than .15 it would have to be less than .15*460= 69
(69-73.6)/7.863= -.59 which has a probability of .2776
2.)
the mean is 2.3
I am not sure if the standard deviation is 3 or .3 (picture is kind of blurry)
I am thinking that it's three which would mean that the standard deviation would be √(3²*(1/5))= 1.342
(2-2.3)/1.342= -.22 = .4129

Answer:
X = 8.3 (shortened)
<u>Steps for answer!</u>
1. Subtract 2.5x from both sides.
1.5=4x-11-2.5x
2. Simplify 4x-11-2.5 to 1.5x-11
1.5=1.5x-11
3. Add 11 to both sides.
1.5+11=1.5x
4. Simplify 1.5+11 to 12.5.
12.5=1.5x
5. Divide both sides by 1.5.
12.5/1.5=x
6. Simplify 12.5/1.5 to 8.3333338.333333.
8.333333=x
7. Switch sides.
x=8.333333
