Answer:
54 or 15
Step-by-step explanation:
x = any number
x = 3
First solve the brackets:
2x + 3
(2x3) + 3 = 9
2x = 6
I can help you up to here because the question isn't worded properly.
If you are multiplying then it would be: 9x6 = 54
If you are adding then: 9+6 = 15
Hope this helps!
Solution :
It is given that the mean and the standard deviation for a sample of 24 domestic cars is 35.696 MPG and 4.931 MPG respectively and the mean and the standard deviation for a sample of 16 cars is 34.345 MPG and 7.118 respectively.
The 90% confidence level for the men difference between the two samples is (-2.906, 2.844).
We know that the confidence interval is calculated to determine the mean difference among the two samples with the specified level of confidence.
Therefore, we can say that with 90% confidence, we have the 90% chances that the true mean differences will be within the range of -2.906 MPG to 2.844 MPG.
Thus, it is required 90% confidence interval interpretation.
Answer is $30.75
19.68÷16=1.23
1.23×25=30.75
90 because how many more means to subtract so u subtract 150 from 60 and you will get 60.
