Answer:
The required inequality is .
Step-by-step explanation:
Consider the provided information.
Kira eats either a burrito containing 490 milligrams of sodium or a peanut butter sandwich containing 700 milligrams of sodium.
let <em>x</em> is the number of burritos and <em>y</em> is the number of peanut butter sandwiches.
If she takes x numbers of burritos which containing 490 milligrams of sodium or y numbers of peanut butter sandwich which containing 700 milligrams of sodium. This can be written as:
490x+700y
Her doctor told her to reduce her sodium to no more than 4,000 milligrams per week.
No more than 4,000 milligrams of sodium means, she can take less than or equal to 4,000 milligrams of sodium.
The inequality sign used for less than or equal to is "≤".
Therefore, the required inequality is .

Step-by-step explanation:
For the first and last two characters, there are ten possible digits (0 through 9) for each character.
For the second through sixth character, there are 26 possible letters (A through Z) for each character.
The number of all possible license plate combinations "n" is given by the multiplication of each digits range of possible outcomes:
Since there are no restrictions for repeated characters, there are 456,976,000 different license plate numbers are possible.
Answer:
Due to the higher z-score, Norma should be offered the job
Step-by-step explanation:
Z-score:
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
Whoever has the higher z-score should get the job.
Norma:
Norma got a score of 84.2; this version has a mean of 67.4 and a standard deviation of 14.
This means that
So
Pierce:
Pierce got a score of 276.8; this version has a mean of 264 and a standard deviation of 16.
This means that
So
Reyna:
Reyna got a score of 7.62; this version has a mean of 7.3 and a standard deviation of 0.8.
This means that
So
Due to the higher z-score, Norma should be offered the job
