Answer:

x=0

Step-by-step explanation:

3=x+3−5x

3=x+3+−5x

3=(x+−5x)+(3)(Combine Like Terms)

3=−4x+3

3=−4x+3

Step 2: Flip the equation.

−4x+3=3

Step 3: Subtract 3 from both sides.

−4x+3−3=3−3

−4x=0

Step 4: Divide both sides by -4.

−4x

−4

=

0

−4

x=0

I need help with the incorrect ones please
Morgarella [4.7K]

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
