-1.5 ------ f(x) = 3(-1.5) - 5
= -4.5 -5
= 9.5
2 -------- f(x) = 3(2) - 5
= 6 -5
= 1
4 -------- f(x) = 3(4) - 5
= 12 - 5
= 7
(9.5, 1 , 7)
Steps:
1) Draw the circle and mark the center (A) and the given point (B)
2) Draw a line that passes through the center (A) and the given poiint (B).
3) Draw a perpendicular line to the segment AB.
The last line drawn is tangent to the circle at the given point.
Answer:
your answer would be z= y over w - x
I am not for sure that what im about to type is the right answer but if im not wrong the amswer is 1over4
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Assum a normal distribution :
Mean (m) = 140 mm
Standard deviation (sd) = 20 mm
The percentage of people with blood pressure between 115 and 165 mm.
Zscore = (x - m) / sd
X = 115 mm
(115 - 140) / 20
-25/20 = - 0.625 = - 0.63
P(z<-0.63) = 0.2643
X = 165 mm
(165 - 140) / 20
25/20 = 0.625 = 0.63
P(z< 0.63) = 0.7357
0.7357 - 0.2643 = 0.4714 = 47.14%
B.) The percentage of people with blood pressure between 140 and 165 mm.
Zscore = (x - m) / sd
X = 140 mm
(140 - 140) / 20
0/20 = 0 = 0
P(z<0) = 0.5000
X = 165 mm
(165 - 140) / 20
25/20 = 0.625 = 0.63
P(z< 0.63) = 0.7357
0.7357 - 0.5000 = 0.2357 = 23.57%
C.) ___ The percentage of people with blood pressure over 165 mm.
X = 165mm
(165 - 140) / 20
25/20 = 0.625 = 0.63
1 - P(z< 0.63) = 0.7357
1 - 0.7357 = 0.2643 * 100% = 26.43%
