Answer:
Approximately 16% of adults have a pulse rate higher than bonnie'.
Step-by-step explanation:
A normal random variable with mean Mu = 69 and standard deviation sd = 9.5 is standardized with the transformation:
Z = (X - Mu) / sd = (X - 69) / 9.5
For a pulse rate value of 78.5, Z = (78.5 - 69) / 9.5 = 1.0
P (X <78.5) = P (Z <1.0) = 0.8413.
P (X> 78.5) = P (Z> 1.0) = 0.1587.
The standard score for the Bonnie's pulse rate is 1.0.
Bonnie's pulse rate is at the 1.0 standard deviations above the mean.
Approximately 16% of adults have a pulse rate higher than bonnie'.

20. i suck :D
21. To compare 0.7 and 5/8, you would have to first turn the decimal into a fraction. After you have your fraction you want to simplify it down to the smallest fraction and compare with 5/8. You also want to find the common denominator.
3562 is greater than 979, 3562>979 Because 3562 is bigger than 979. (Did this help?)
Answer:
418
Sn = ∑ 3 +4(n-1)
n=1
Step-by-step explanation:
3,7,11,15,.....1671
a1 =3
d = 4 (7-3=4)
an = a1 + d(n-1)
an = 3 +4(n-1)
We need to determine the last term
1671 = 3 +4(n-1)
Subtract 3
1671-3 = 3-3 +4(n-1)
1668 = 4(n-1)
divide by 4
1668/4 = 4(n-1)/4
417 = n-1
Add 1 to each side
418 = n
418
Sn = ∑ a1 +d(n-1)
n=1
418
Sn = ∑ 3 +4(n-1)
n=1
