<span>х is the first number
(x + 1) is the second number
(x + 2) is the third number
(x + 3) is the fourth number
</span>
x + x+1 + x+2 + x+3 = 230
4x + 6 = 230
4x = 230 - 6
4x = 224
x = 224/4
x = 56 the first number
56 + 1 = 57 the second number
56 + 2 = 58 the third number
56 + 3 = 59 the fourth number
Answer: 56, 57, 58, 59.

The weighted mean is used to calculate the mean of numbers which don't have the same "weight" or statistical relevance. In this case, that relevance is based on the sample size of each group from which the mean reaction times were obtained.

Remember that cents has a decimal when put in an equation.
250(x + 11) + 250x = 4250
250x + 2750 + 250x = 4250
500x + 2750 = 4250
500x = 1500
x = 3 cents (pencils)
x+11 = 14 cents (pens)hope this helps u
