Answer:
The 95% confidence interval for the mean change in blood pressure, , is 1.744 < < 2.816
Step-by-step explanation:
The parameters given are;
The number of people in the sample, n = 9
The average drop in blood pressure, = 2.28 points
The standard deviation, σ = 0.82
The confidence level = 95%
The formula for confidence interval with a known mean is given as follows;
Where:
= z - score at 95% confidence level = 1.96
We therefore have;
Which gives the 95% confidence interval for the mean change in pressure, , is given as follows;
1.744 < < 2.816
Answer:
When two lines are crossed by another line (called the Transversal): The pairs of angles on one side of the transversal but inside the two lines are called Consecutive Interior Angles.
y=5/3x
this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis
If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3
So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways
A plane is a three-dimensional form that has length and width by minimum thickness.
Answer:
1233cm^2
Step-by-step explanation:
a of triangle = 1/2 bh
1/2 x 12 x 9 = 54
108 x 2 = 108
a of regtangle = l x w
25 x 15 = 375
375 x 3 = 1125
total surface area = 1125 + 108 = 1233cm^2
