you need to substitute.... then do: 160.4(mean)+2(x)*27(z)= 214.4lb
Answer:
1/4 of 10 is 2 1/2
then 7 1/2 is left
9x+11-4x+3=24
always combine like terms first. Combine all the x's and all numbers.
5x+14=24
Therefore, the answer is D.
The probability = outcome/total outcomes
The total of the outcomes is the total number of the letters of the given word, then
The total outcomes = 11
The outcome is the number of letter "s" in the word
The outcome = 4, then
The probability of "s" is

To change it to percent multiply it by 100% and round it to the nearest 1 decimal place

The answer is 36.4%
