Step-by-step explanation:
First we need to find what is 20% off $23,999
1) = 20/100 x 23,999= $4,799
To find the decrease over 6 years :
2)= $4,799 x 6 = $28,798.8
Finally
= 28,798.8-23,999= $4,799.8
$4,799.8 is the final value.

Answer:
Kim is 24 years older than Tom Kim and Tom are twins. These two statements are not compatible, unless the mother of Kim and Tom was in labor for 24 years LOL
Second statement
Savannah and Sebastian are the same age (twins)
X being Ryan's age the correct answer is 24+x = 5x
D is the correct answer
To solve 24+x= 5x
Subtract x from each side
24= 4x
Divide each side by 4
6= x
Savannah is 30 Sebastian is 30 Ryan is 6

Answer:
0.8224
Step-by-step explanation:
Data
- standard deviation, sd: $10
- first value of interest, x1: $63
- second value of interest, x2: $90
z-score for x1:
z1 = (x1 - mean)/sd = (63 - 76)/10 = -1.3
z-score for x2:
z2 = (x2 - mean)/sd = (90 - 76)/10 = 1.4
The proportion of wrist watch prices are between $63 and $90 is:
P(z1 < z < z2) = P(z < 1.4) - P(z < -1.3)
P(z < 1.4) = 0.9192 (see first picture attached)
P(z < -1.3) = 0.0968 (see second picture attached)
P(z1 < z < z2) = 0.9192 - 0.0968 = 0.8224
