3+5+1= 9
divide 36.90 by 9 and you get 4.1 for every 1 part they get. Reilly gets 3 parts so multiply 4.1 by 3 and you get $12.30 as reilly’s total. maria gets 5 parts so multiply 4.1 by 5 and you’ll get $20.50 as maria’s total and then tamara will get $4.10. answer is $20.50 since that’s how much maria got!
Answer:
Step-by-step explanation:
Given is a sample of contents of a random sample of 10 containers as follows:
10.1 9.7, 10.5, 10.4, 9.8, 9.7, 9.4, 9.9, 10.7, and 9.7 liters.
To check whether the mean is 10.1 litres.
Set up hypothesis as
(two tailed test at 10% level of significance)
Sample mean =9.9
Sample std dev=0.420185
Std error =0.1329
n = 10
df = 9
Mean difference = 9.9-10.1 =-0.2
Test statistic t = -0.2/0.1329 =-1.505
p value= 0.1666
Since p value is >0.10 we accept null hypothesis
Conclusion:
the average content of containers of a particular lubricant is 10.1 liters can be taken as true at 90% level of confidence
I don't think you finished the ? but what i see the answer is 3/x
Answer:
$50.40
Step-by-step explanation:
The garden has an area of ...
(15 ft)(12 ft) = 180 ft²
Amy wants to cover 1/4 of that with flowers, so the area devoted to flowers is ...
(1/4)(180 ft²) = 45 ft²
The cost for each square foot is $1.12, so the cost of the flowers will be ...
($1.12/ft²) × 45 ft² = $50.40 . . . . cost to cover 1/4 of the garden with flowers
A) 26 + 18 = D
Where D = Dad's age.
B) No it isn't. You solve the above equation and it equals 44.
C) The first age comparison is 26 years apart, both going up by 8 each time, so by adding 8 to 36, it equals 44, which isn't 42.
