At a small company, the heed of human resources wants to examine salary to prepare annual reviews. he selects 28 01 - stocking clerk to 99 prosident. he plots salary against job type and finds a strong linoarolationahip with a corrlston of 0.96. the regresion ourgut gs salary - 15827.9+ 1939.1 job type. interpret this model and describe what he can conlude from this analynis. employees at rendom with job types ranging from 1-click the icon to view the plot. choose the correct answer below o a. the model is useful because the job type can be determined from the salary the positive slope indicates that salary increased from job type 01 to job type o b. the model is useful because salary can be determined from the job type. the positive slope indicates that salary increased from job type 01 to job type o c. the model is meaningless because the variable job type is not quantitative. the slope makes no sense because job type has no units. he should use a bar ○ d the model is meaningless boause the variable job type is not quantitative. the slope makes no sense becau骑sales has no units. the scatterplot used is 99. 99. chart of average salary for the different job types. fine, but the regression output is meaningless

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
