Answer:
8 miles a day
Step-by-step explanation:
First you have to subtract the amount of miles she had already gone.
60 - 12 = 48
Next you have to divide by the remaining amount of days (6 days).
48/6 = 8

Answer:
Where 
and 
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule:
Answer:
Fermented cucumbers
Step-by-step explanation:
A pickled cucumber is a cucumber that has been pickled in a brine, vinegar, or other solution and left to ferment for a period of time, by either immersing the cucumbers in an acidic solution or through souring by lacto-fermentation. Pickled cucumbers are often part of mixed pickles.
The age of the van owned = 12 years
The age of the truck owned = 29 years
Step-by-step explanation:
Here, the given question is INCOMPLETE.
Laura takes very good care of her vehicles. She owns a blue van and a red truck. Although she bought them both new, she has owned the truck for 17 years longer than she has owned the van. If the sum of the ages of the vehicles is 41 years, how old is the van and how old is the truck?
Let us assume the number of years Laura has owned the van = S years
So, according to the question:
The number of years she has owned truck = S + 17 years
Now, Sum of the age of ( Truck + Van) = 41 years
⇒ (S + 17 years) + (S years) = 41 years
or, 2 S + 17 = 41
or, 2 S = 4 1 -1 7 = 24
or, S = 24/2 = 12 years
or, S = 12 years
Hence the age of the van owned = 12 years
The age of the truck owned = S + 17 = 12 + 17 = 29 years
