A consumer surveys 49 televisions. 80% cost between $250.00 and $350.00. The administrator decides to calculate a 95% confidence interval for this proportion.

Standard error =

The estimate is
%. The reliability factor is
The standard error is (to nearest hundredth)
The confidence interval is from 68% to 92% (to the nearest percent). Put an x in the box.
true
false

What is the relationship between all triangles that can be drawn given the same three angles

Four individuals pool money together to start a new business and agree to split the profits equally. n invests $6,000, x invests $2,000, y invests $8,000 and z invests $4,000. if the profits for the first month were $100,000, y receives than if the profits were divided in proportion to how much they invested.

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
