Statement : Val spent $ 34 for the 2 items
contradiction : Neither of the 2 items that Val bought cost more then $ 15
think about it....if neither of them cost more then 15....lets say they cost 15 each...then there is no way he spent $ 34.....he would spend at most $ 30
Answer and Step-by-step explanation: Scaterplot is a type of graphic which shows the relationship between to variables. In this question, you want to determine if there is a linear relationship between overhead widths of seals and the weights. So, the hypothesis are:
H₀: no linear correlation;
H₁: there is linear correlation;
In this hypothesis test, to reject H₀, the correlation coefficient r of the data set has to be bigger than the critical value from the table.
With α = 0.05 and n = 6, the critical value is 0.811.
The linear correlation is calculated as:
r = n∑xy - ∑x.∑y / √[n∑x² - (∑x)²] [n∑y² - (∑y)²]
r = 
r = 0.9485
Since r is bigger than the critical value, H₀ is rejected, which means there is enough evidence to conclude that there is linear correlation between overhead widths and the weights.
In the attachments is the scaterplot of the measurements, also showing the relationship.
Answer:

Step-by-step explanation:
Answer:
Greatest: Denmark
Least: U.S.
Step-by-step explanation:
The population density is calculated by dividing the population by the area.
U.S.
Population density = 272,648,000/9,364,520 = 29.1
Denmark
Population density = 5,248,000/42,077 = 124.7
Ghana
Population density = 18,339,000/237,533 = 77.2
Greatest: Denmark
Least: U.S.
