- How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers assigned newly laid eggs to one of two temperatures: hot or cold. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother. 80% (32 out of 40) hot eggs hatched. 55% (33 out of 60) cold eggs hatched. Please calculate the strength of the association by calculating Cramer's V.N Netflix A To-do Meet - mdg-wawx-skn C Clever | Portal A ola.performancematters.com/ola/ola.jsp?clientCode=mdCarrollcty# Performance Matters Welcome, Ayanna Cocilova! Question 2 of 6 - PO CCPS.20-21.math.grade7.B1: Section 1- Calculator enabled Questic Part A At a local restaurant, the cost of a small salad was marked up 30% after a recent drought destroyed most of the local lettuce crop. Determine the new cost if the price prior to the drought was $1.80. O $0.54 O $1.30 O $2.10 O $2.34 Part B The new total cost of the salad, including sales tax is https://ola.performancematters.com/ola/ola.jsp?clientCode-mdCarrollcty#The authors of a paper investigated whether water temperature was related to how far a salamander would swim and whether it would swim upstream or downstream. Data for 14 streams with different mean water temperatures where salamander larvae were released are given (approximated from a graph that appeared in the paper). The two variables of interest are x = mean water temperature (°C) and y = net directionality, which was defined as the difference in the relative frequency of the released salamander larvae moving upstream and the relative frequency of released salamander larvae moving downstream. A positive value of net directionality means a higher proportion were moving upstream than downstream. A negative value of net directionality means a higher proportion were moving downstream than upstream. y 0.3 0.2 Mean Temperature (x) 0.1 0.0 -0.1 6.22 8.01 5 8.67 10.61 12.5 11.94 12.55 18.03 18.24 (a) Construct a scatterplot of the data. 19.94 20.3 19.02 17.78 19.67 USE SALT Net…

As potential explanatory variables are considered: X1 average annual income per person in the family (in USD), X2 – number of people in the family, X3 – nature of employment of the head of household If X3=1, when the head of the family is self-employed, X3=0, when the head of the family is an employee Based on the collected data, linear correlation coefficients between variables were calculated and obtained 0,84 R, = -0,47 [1 -0,55 0, 62 R= 1 -0,42 0,75 1 Using Hellwig's method, select the optimal combination of explanatory variables for the tourism and recreation expenditure model.
- Q1) A retail. Store stocks two types of shirts A and B. These are packed in attractive cardboard boxes. During a week the store can sell a maximum of 400 shirts of type A and a maximum of 300 shirts of type B. The storage capacity, however, is limited to a maximum of 600 of both types combined. Type A shirt fetches a profit of SR 2/- per unit and type B a profit of SR. 5/- per unit.
