The cost of a home depends on the number of bedrooms in the house. suppose the following data is recorded for homes in a given town price (in thousands) 300 250 400 550 317 389 425 289 389 559 no. bedrooms 3 3 4 5 4 3 6 3 4 5 a) make a scatterplot b) fit the data with a least squares regression line. c) give a 95% confidence interval for the slope. d) if one house has one more number of rooms than another house, how much additional cost would we expect for the price? e) test the hypothesis that an extra bedroom costs $60,000 against the alternative that it costs more.

step-by-step explanation:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
