The function M(s) = 225 + 0.65s represents the material cost of manufacturing gardening scissors when s scissors are produced. T
Llana [10]

Answer:

\frac{279 + 1.8s}{s}                                                        

Step-by-step explanation:

The  material cost of manufacturing gardening scissors when s scissors are produced : M(s) = 225 + 0.65s

The labor cost for producing s scissors: L(s) = 54 + 1.15s

So, total cost of producing s scissors =  M(s)+L(s)

                                                              =  225 + 0.65s+54 + 1.15s

                                                              =  279 + 1.8s          

So, total cost for s scissors =  279 + 1.8s    

So, manufacturing cost for 1 scissor=  \frac{279 + 1.8s}{s}                                                        

Hence the manufacturing cost per scissors is  \frac{279 + 1.8s}{s}

The water temperature at the beach
tester [92]

Answer: 69˚

All of the graphs for the surf breaks presented on Surf-Forecast.com are on the same scale to enable comparison between locations around the world.

Ocean Beach water temperatures peak in the range 13 to 17°C (55 to 63°F) on around the 8th of September and are at their lowest on about the 7th of April, in the range 10 to 14°C (50 to 57°F). The highest water temperatures at Ocean Beach in early to mid September are ideally suited to a 4/3mm wetsuit + 3mm boots, although a 5/3mm wetsuit may be preferable for longer sessions and cold windy days. At its lowest in the first part of April, low water temperatures at Ocean Beach are suited to a 5/4mm or 5/3mm good quality wetsuit with neoprene gloves and 3mm boots. You will need a hood if it's windy or the air is cold.

Actual sea surface water temperatures close to shore at Ocean Beach can vary by several degrees compared with these open water averages. This is especially true after heavy rain, close to river mouths or after long periods of strong offshore winds. Offshore winds cause colder deep water to replace surface water that has been warmed by the sun. Air temperature, wind-chill and sunshine should also be considered before deciding on the kind of wetsuit needed to stay warm when surfing at Ocean Beach.

Hope this. helps!~

What scale of measurement is being used when a teacher measures the number of correct answers out of 50 on a quiz for each stude
seropon [69]
AssessmentA broad term used to describe a systematic process used to collect information.TestA systematic procedure for measuring a sample of behavior from a domain.MeasurementThe process of assigning numbers to some characteristic according to some specified rules.Item Difficulty for a test item scored incorrect (0) or correct (1) from a classical test theory perspectiveProportion of individuals out of the total number of individuals who answered the item correctly (40 students out of 100 answered the item correctly = .40; the bigger the number the "easier" the item).Item Discrimination for a test item scored incorrect (0) or correct (1) from a classical test theory perspectiveDegree to which an item differentiates people who score high on the total test from those who score low on the total test. Item-total correlation is one way of defining item discrimination. You want items to have positive values for item discrimination.Item Variance for a test item scored incorrect (0) or correct (1) from a classical test theory perspective<span>Item variance = (proportion of individuals who answered the item correctly) x (proportion of individuals who answered the item incorrectly)
p x q</span>Covariance between 2 variablesCovariance is a measure of the linear association between 2 variables with the 2 variables represented in their original units (not standardized). Unlike a correlation coefficient that goes from -1 to +1, the value of a covariance can go from - infinity to + infinity.Pearson product moment correlation (r) between 2 variablesPearson correlation (r) is a measure of the linear association between 2 variables with the 2 variables being standardized (mean = 0, SD = 1). Correlation coefficient that goes from -1 to +1Variance-Covariance MatrixIn a variance-covariance matrix the variances of the variables are represented in the diagonal of the matrix; the covariances between pairs of variables are represented in the off diagonalConstructAn unobserved or latent variable that is used to explain some observed phenomenon or experience. Latent variables are represented by a circle in measurement models.Reflective Measurement ModelA measurement model that holds that holds that a construct is viewed as the cause of the observed or measured variables.Formative Measurement ModelA measurement model that holds that holds that the observed or measured variables are the cause of the latent variableOperational Definition of a ConstructA definition that is clear and detailed that defines the construct by specifying the procedures used to measure a constructContent ValidityOne of five sources of measurement validity evidence that often involves experts who are knowledgeable about the construct making evaluative judgments about whether the items used to measure the construct adequately reflect the definition of the construct.Convergent ValidityA construct measured by 2 methods should produce a moderate to strong correlation between the 2 measures (e.g., a person's anxiety determined by a questionnaire and a person's anxiety determined by a structured interview).Discriminant ValidityScores on the measure are not related to other measures that are theoretically different (if Grit is theoretically different from Conscientiousness, the correlation between these measures should not be strong)Nomological NetworkAn approach used as part of the process of gathering evidence of construct validity of educational and psychological measures. Similar to the research process, relationships based on theory between measures that the new measure should relate to and measures it should not relate to are tested.<span>Reliability</span>

If sin theta = -5/7 , which of the following are possible?
Sav [38]

Solution:

we are given that

sin \theta=-5/7

As we know that

cos \theta =\sqrt{1-sin^2 \theta}  \\

Substitute the value we get

cos \theta=\sqrt{1-(\frac{-5}{7})^2}  \\&#10;\\&#10;cos \theta=\sqrt{1-(\frac{25}{49})}  \\&#10;\\&#10;cos \theta=\sqrt{(\frac{24}{49})} =\frac{\sqrt{24}}{7}\\

Since sec \theta=\frac{1}{cos \theta}\\

So here sec \theta=\frac{7}{\sqrt{24}}\\

As we know that

tan \theta=\frac{sin \theta}{cos \theta}\\&#10;\\  \text{Substitute the values we get}\\&#10;\\&#10;tan \theta=\frac{-5/7}{\frac{\sqrt{24}}{7}}\\&#10;\\&#10;tan \theta=\frac{-5}{\sqrt{24}}\\

Hence the correct option is C.
