The weights of steers in a herd are distributed normally. the standard deviation is 200 lbs and the mean steer weight is 1100 lbs. probability find the probability that the weight of a randomly selected steer is between 760 and 1280 lbs. (round your answer to 4 decimal places) normal table -infinite to -z normal table - infinite to z

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

the equation simplified is 7/8. but the lcd is 8.
