Answer:
0.41791
Step-by-step explanation:
let x be the number written to the thousandth place then,
x times thousands = 417.91
or, x = 417.91/1000
therefore, x = 0.41791
and so
0.41791 thousand = 417.91
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.
I believe you want us to simplify the expression.
Note that 5 + (-6) is the same as 5 - 6
Simplify
4 + 5 = 9
9 + (-6) = 9 - 6 = 3
3 is your answer
hope this helps
Answer:
A slope perpendicular would be -1/5x and a slope parallel would be 5x
Step-by-step explanation:
Perpendicular means about the opposite, or a reciprocal, which is -1/5x. Parallel means the same so it would be 5x.
