Find the opposite of adding 15. So it would be subtracting 15. So subtract 15 on both sides. So it would have 2/3x on the left and then 2 on the other side. (2/3x=2) Now find the opposite of multiplying 2/3. It is dividing 23/3. So divide 23/3 on both sides. So multiply 2/3 times 1/2. It would equal 3. x = 3
Hope this helps. :-)
The fastest typist is Charlie at 60wpm. Let's figure out how many words he can type in 30 minutes using place value strategies.
6 * 3 = 18
Now, move the decimal two places to the right because there is one zero in 60 and one zero in 30.
1800.
Charlie can type 1800 words in 30 minutes.
The slowest typist is Jerome, at 40 wpm. Let's figure out how many words he can type in 30 minutes using place value strategies.
4 * 3 = 12
Now, move the decimal two places to the right because there is one zero in 40 and one zero in 30.
1200.
Jerome can type 1200 words in 30 minutes.
Now, subtract Charlie's words in 30 min by Jerome's words in 30 min.
1800 - 1200 = 600
Charlie can type 600 more words in 30 minutes than Jerome.
Answer:
The 88% confidence interval for the proportion of defectives today is (0.053, 0.123)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
88% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 88% confidence interval for the proportion of defectives today is (0.053, 0.123)
