Answer:
0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 114.8 mm Hg
Standard Deviation, σ = 13.1 mm Hg
Sample size = 23
We are given that the distribution of systolic blood pressures is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling:
P(blood pressure is between 119 and 122 mm Hg)
0.0579 is the probability that mean systolic blood pressure is between 119 and 122 mm Hg for the sample.
Answe The locations of E' and F' are E' (−8, 0) and F' (0, 4), and lines g and g' intersect at point F.
The locations of E' and F' are E' (−4, 0) and F' (0, 2), and lines g and g' are the same line.
The locations of E' and F' are E' (−2, 0) and F' (0, 1), and lines g and g' are parallel.
The locations of E' and F' are E' (−1, 0) and F' (0, 0), and lines g and g' are not related.
are your answer options I went with.. The locations of E' and F' are E' (−2, 0) and F' (0, 1), and lines g and g' are parallel.
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
AB + BC = AC = 28
the way from A to C goes through B.
so, the total way of A to C is the sum of the way from A to B and then from B to C.
=>
(5x + 10) + (2x + 25) = 28
7x + 35 = 28
7x = -7
x = -1
Pretty much you’re going to need to subtract the -9x to get it on the other side, so that you get y= 9x+6
