Y+2=3(x+1) in point slope form
y=3x+1 in slope intercept form
The slope would be -2 because you would use the equation m= y2-y1/x2-x1
Answer:
1.25% of all the 8,000 people who tried the shampoo had a mild allergic reaction
Step-by-step explanation:
Divide 8,000 by 64 to get the unsimplified percentage
Then put a dot between 1 and 2 to get the percentage to get the percentage, 1.25%
Answer: A term is is a single mathematical expression. For example, a is a term, 12 is a term, 2ab^2 are also a term. that means it's the things without symbols in polynomials
Step-by-step explanation:
For this problem, you can write this expression as: x/2 + y - 3, you can clearly see that there are three terms total in this problems.
Answer:
The 90% confidence interval for the population mean is (300.78, 315.22).
Step-by-step explanation:
We have to calculate a 90% confidence interval for the mean.
The population standard deviation is know and is σ=17.
The sample mean is M=308.
The sample size is N=15.
As σ is known, the standard error of the mean (σM) is calculated as:
The z-value for a 90% confidence interval is z=1.645.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 90% confidence interval for the population mean is (300.78, 315.22).
