Answer:
3. 9 - (n ÷ 5 ) 5. 8 x ( 5 x t ) (( i don't know the others ))
Step-by-step explanation:
5x - 3y = 10
x + y = 7......multiply by -5
------------------
5x - 3y = 10
-5x - 5y = -35 (result of multiplying by -5)
------------------add
-8y = -25
y = 25/8
x + y = 7
x + 25/8 = 7
x = 7 - 25/8
x = 56/8 - 25/8
x = 31/8
solution is (31/8 , 25/8)
You're just a step away from the equation of the line that's perpendicular to [ y = 5/6 x + 7 ]. ... You know that its slope is -6/5 and that it contains the point (3, 2). ... Find the equation of that line. Then find the point where the two lines intersect. Then find the distance between that point and (3, 2). SIR !
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.
Answer:
D (the last one)
Step-by-step explanation:
-x would equal 0 on the x axis and -4 would be plotted at -4 on the y axis
