Answer: 2
Step-by-step explanation:
So, you need to put (4,7) (2,3) into m=y2-y1/x2-x1 form.
4= x1 7=y1 2=x2 3=y2
3-7= -4
2-4= -2
-4/-2=2
There are no options, but I would assume that these sequences would be geometric: 16, -8, 4, -2, 1 -15, -18, -21.6, -25.92, -31.104, 625, 125, 25, 5, 1 can possibly be the correct ones.
Answer:
Step-by-step explanation:
Given that the sample mean for a random sample of 100 cars is 27.2 miles and assume the standard deviation is 2.4 miles.
H0: x bar = 25.9
Ha: x bar ≠ 25.9
(Two tailed test at 95% confidence)
Alpha =0.05
The hypothetical mean is 25.900
The actual mean is 27.200
The difference between these two values is 1.300
The 95% confidence interval of this difference:
From -3.462 to 6.062
t = 0.5417
df = 99
standard error of difference = 2.400
The two-tailed P value equals 0.5893
Since p >0.05 this difference is considered to be not statistically significant.
Answer:
Option C) The data are discrete because the data can take on specific value.
Step-by-step explanation:
We are given the following in the question:
The numbers of languages spoken by different people.
The data would include points like English, Hindi, Marathi, and many more.
Thus, the data is discrete because the number of languages will always be expressed in whole numbers and thus it cannot take any value within an interval.
The value is calculated and not measured.
Thus, the correct answer is
Option C) The data are discrete because the data can take on specific value.
