Answer: CURRENT AGES: C = 35, D = 5 AGES IN 5 YEARS TIME: C = 40, D = 10
Step-by-step explanation:
We need to use algebra here.
Let C = Coffee's age
Let D = Daughter's age
C = 7 x D
C + 5 = 4 x (D + 5)
C + 5 = 20 + 4D
C = 15 + 4D
7D = 15 + 4D
D = 5
C = 7 x 5
C = 35
Answer:
There is a difference in mean hand span between male and female if you notice the difference between their averages. 2cm is quite significant
female mean = 19.6 cm and male mean = 21.6 cm
Step-by-step explanation:
a.) There is a significant difference.
take P( Z < ( 19.6 - 21.6) / 1) = P(Z < -2) = 2% probability of assuming that male and female means are the same. too low to think like that.
b.) Differ by 2cm. MAD= Mean Absolute Deviation , MAD within their own data set seem similar
C.) The variability in hand spans among male and female are very similar, since they both have the same MAD = 1.0
19 1/2 appointments because 6 1/2 hours divided by 1/3 of an hour (when the stylist schedules an appointment each time) equals 19 1/2. hope this helps!
Answer:
$22,000
Step-by-step explanation:
So, we would multiply 20,700 and 7%. That equals to 1,449
Then we would multiply 1,449 and 15 that equals 21,735.
SO after 15 years it will be worth 21,735
But then we would round it up, because it is above 500.
So the total value rounded up will be $22,000
Hope this helps!
