The invasive diatom species Didymosphenia geminata has the potential to inflict substantial ecological and economic damage in rivers. An article described an investigation of colonization behavior. One aspect of particular interest was whether y colony density was related toxrock surface area. The article contained a scatterplot and summary of a regression analysis. Here is representative data x 50 71 55 50 33 58 79 26

(a) Fit the simple linear regression model to this data. (Round your numerical values to three decimal places.) Predict colony density when surface area 70 and calculate the correspanding residual. (Round your answers to the nearest whole number.) colony density corresponding resi 71 and calculate the corresponding residual. (Round your answers to the nearest whole number.) Predict colony density when surface area colony density corresponding residual How do the res duals compare? The residual for the first point is positive, while the residual for the second point is negative. The residuals for both points are negative. The residual for the first point is negative, while the residual for the second point is positive. The residuals for both points are positive.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
