Answer: 0.9332.
Step-by-step explanation:
Claim : College Algebra final exam score of engineering majors equal to 88.
Given that : The test statistic is z equals to 1.50.
To find the p-value (Probability value), we use standard normal distribution table, and search the p-value corresponds to the z-score.
In a Standard Normal Distribution Table below, the p-value corresponds z equals 1.5 is 0.9332.
Hence, the p-value is 0.9332.
Let x represent number of bracelets and y represent number of necklaces.
We have been given that a jeweler made 7 more necklaces than bracelets. This means that number of necklaces will be . We can represent this information in an equation as:
We have been given that the amount of gold in each bracelet is 6 grams, so amount used for x bracelets would be grams.
We are also told that the amount of gold in each necklace is 16 grams, so amount used for y necklaces would be grams.
Since the jeweler used 178 grams of gold, so we will equate the amount of gold used in x bracelets and y necklaces with 178 as:
Therefore, our required system of equations would be:
Answer:
There are 250 nails and 150 screws in the bucket.
Step-by-step explanation:
Let Number of nails in bucket be x.
Also Let number of screws in the bucket be y.
Together, there are 400 fasteners in the bucket.
Hence the equation can be framed as;
Also Given:
The number of nails in the bucket is 50 less than twice a number of screws.
Hence the equation can be framed as;
Substituting the value of x in equation 1 we get;
Now we have value of y we will substitute in equation 1 we get;
Hence there are 250 nails and 150 screws in the bucket.
