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%
Answer:
Hey there!
1+(-5)=1-5
1-5 = -4
Let me know if this helps :)
So as your given angle 4. angle 5 and angle 5 are alternate angles! so from that angle 4=5
and angle 7 equals angle 6 due to opposite angles!
so if it's given that angle 4 is equal to 7
and we found out that 4=5 6=7
we can definitely 5=6
