Refer to the accompanying scatterplot.

a. examine the pattern of all 1010 points and subjectively determine whether there appears to be a strong correlation between x and y.

b. find the value of the correlation coefficient r and determine whether there is a linear correlation.

c. remove the point with coordinates (1010,22) and find the correlation coefficient r and determine whether there is a linear correlation.

d. what do you conclude about the possible effect from a single pair of values

Need 50 will mark brainliest answer. find the lengths of all the sides and the measures of the angles.

Which graph has a rate of change of zero

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
