The data show the chest size and weight of several bears. find the regression equation, letting chest size be the independent (x) variable. then find the best predicted weight of a bear with a chest size of 39 inches. is the result close to the actual weight of 126 pounds? use a significance level of 0.05.chest_size_(inches) weight_ (pounds)44 21341 20641 17655 30951 30042 178what is the regression equation? y=+ (round to one decimal place as needed)what is the best predicted weight of a bear with a chest size of 39 inches? y= (round to one decimal place as needed.)is the result close to the actual weight of 126 pounds? a. this result is very close to the actual weight of the bear.? b. this result is close to the actual weight of the bear.? c. this result is exactly the same as the actual weight of the bear.? d. this result is not very close to the actual weight of the bear.?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

i believe the answer is the polygon, heptagon.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
