Let n be Fritzs' car speed, and n+12 be the speed of the train. Then:
1/2 (n)=1/3 (n+12)
2n+24=3n
n=24 mph
n+12=36 mph
Fritz travels 12 miles to work.
30 min @24mph=12 miles
20 min @36mph=12 miles

Answer: 3
<u>Step-by-step explanation:</u>
<u>Wins</u> <u>Losses</u> <u>Pattern</u>
18 2 18 ÷ 2 = 9
45 5 45 ÷ 5 = 9
36 4 36 ÷ 4 = 9
27 x
Using the same pattern we have
27 ÷ x = 9
→ x = 3
Answer:
1.2
Step-by-step explanation:
Given that X is Normally distributed random variable with an unknown mean μ and known standard deviation 6
Hence we can say for a sample of size 100, the sample mean will have a std deviation of = 
Since population std deviation is known we can use Z critical value for finding out the confidence interval
For 95% using (68-95-99.7 rules) we have z critical value =2
Hence margin of error =2(std error) = 1.2
Confidence interval 95%
Lower bound = Mean - margin of error = Mean -1.2
UPper bound = Mean +1.2
Hence , 95% of all of these values of x should lie within a distance of __1.2___ from μ .
Answer:
4 cups of milk chocolate
Step-by-step explanation:
if there are 6 cups in total, then you can see that 1:2 is equal to 3 cups in total. If you multiply both sides of the ratio by 2, then you get 2:4, which is 6. You have to add the chocolate together to find how much it equals in total. Because it's white chocolate to milk chocolate, that would be 2:4, so there are 4 cups of milk chocolate.
Irregular polygons because they can have one side a right angle then all the other sides bent up, with leaves a diagonal not being symmetric.
