Answer:
Step-by-step explanation:
d + q = 32
.10d + .25q = 5.00
d + q = 32
10d + 25q = 500
-10d - 10q = -320
10d + 25q = 500
15q = 180
q= 12 quarters
d + 12 = 32
d = 20 dimes
Answer:
Step-by-step explanation:
Let 
be the average of the sample, and the population mean will be 
We know that:
gr
Let 
be the standard deviation and n the sample size, then we know that the standard error of the sample is:
Where
In this case we are looking for:
This is:
or 
Now we get the z score
Looking at the tables for the standard nominal distribution we get
Answer:
Step-by-step explanation:
model C
In order to know the answer, we are going to solve this using proportion.
Given that 4 is the larger wood and 3 is the smaller wood, the cost of the smaller wood is 216 now we are going to find how much is for the larger wood.
Let us represent it this way:
4:3 = x : 216 Let x be the cost of the larger wood.
Just cross multiply and divide
4 x 216 divided by 3 and we get 288. Therefore, the cost is $288. Hope this answer helps.
Convert 1:45 pm to 24-hour system = 13.45
Answer is 13.45 - 10.30 = 3 hours 15 minutes
