Jill's mom bought a generator to keep her appliances running during power outages. The generator is filled with 6.6 gallons of gasoline and consumes an average of 0.75 gallons of gasoline per hour. You can use a function to describe the amount of gasoline remaining in the generator after it runs for x hours. Write an equation for the function. If it is linear, write it in the form h(x) = mx + b. If it is exponential, write it in the form h(x) = a(b). please help

Data on oxide thickness of semiconductors are as follows: 426 432 418 418 421 436 418 408 431 435 423 426 411 434 435 432 411 426 407 439 422 426 412 416 consider this data as a sample of the population. (a) calculate a point estimate of the mean oxide thickness for all wafers in the population. (round your answer to 3 decimal places.) (b) calculate a point estimate of the standard deviation of oxide thickness for all wafers in the population. (round your answer to 2 decimal places.) (c) calculate the standard error of the point estimate from part (a). (round your answer to 2 decimal places.) (d) calculate a point estimate of the median oxide thickness for all wafers in the population. (express your answer to 1 decimal places.) (e) calculate a point estimate of the proportion of wafers in the population that have oxide thickness greater than 430 angstrom. (round your answer to 4 decimal places.)
