Ineed . attached are pictures of the questions. very lost. answers asap . "the table shows latitudes and average temperatures for several cities. use your calculator to find an equation for a line of best fit. round your values to the nearest hundredth. solve this equation to find the temperature in panama city, panama (rounded to the nearest whole number), then identify and interpret the correlation coefficient. city latitude average temperature (°f) calgary, alberta 51.0°n 24 munich, germany 48.1°n 26 marseille, france 43.2°n 29 st. louis, missouri 38.4°n 34 seoul, south korea37.3°n 36 tokyo, japan 35.4°n 38 new delhi, india 28.4°n 43 honululu, hawaii 21.2°n 52 bangkok, thailand 14.2°n 58 panama city 8.6°n ? the equation is y = . the temperature in panama city, panama should be around degrees fahrenheit. the correlation coefficient r is close to -1 or close to -0.5 , which indicates a strong correlation or a weak correlation.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
