A student searches for the book he needs on three shelves
cabinets. The probability that the book is on the first shelf, the second and
the third is 0.9, 0.7 and 0.85, respectively. Find the probability
that:
a) the required book is only on one shelf;
b) there is no required book on all shelves.

Let r = 3. what is the value of r + 58?

Using the given statements, state whether the conditional statement is true or false. p: 7 + 1 = 0 q: 2 + 2 = 5 is p q true or false?

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
