12 x w w is a variable and 12 is a number
Answer: (a) There is a clear outlier in the data.
Step-by-step explanation:
The statement relates that sample= 24
Confidence interval= 80.2 to 89.8.
Now the data does not mention anywhere the standard deviation which is an important parameter in using the t-procedure rather we assume that standard deviation is not known. So, the most worrying part is the skewness and the presence of strong outliers in the t-procedure.
So, the option a) is correct meaning a clear outlier in the data.
Answer:
The exact value of cos(15°) is √(2 + √(3)) / 2.
Answer:
1. has a common factor of 2
2. has a common dividend of 2
3. has a common difference of -10
Number patterns 1 and 2 are geometric sequences so that is why they contain a common factor or dividend
Number pattern 3 is an arithmetic sequence which is why it has a common difference (substracting instead of multiplying or dividing like the first two)
Hope this helps!
Answer:
x = 5
Step-by-step explanation:
3/5x = 1/2x + 1/2
collect like terms =
3/5x - 1/2x = 1/2
6x - 5x/10 =
x/10 = 1/2
2x = 10
x = 5
