Answer:
60%, 0.62, 0.625
Step-by-step explanation:
Step 1: Convert 5/8 to decimal form.
In order to convert a fraction to a decimal, we divide the numerator (top) by the denominator (bottom). By dividing 5 by 8, we can get the fraction 5/8 in decimal form, which is 0.625
Step 2: Convert 60% to decimal form.
In order to convert a percentage to a decimal, all we have to do is move the percentage's decimal point two spots to the left. Since 60% shows us no decimal point, we can assume that it comes directly after the 0, or 60.0%. After moving the decimal point two spaces to the left, we find that 60% = 0.60 in decimal form.
Step 3: Compare the numbers.
Since 0.62 is already in decimal form, we don't need to make any changes. This means that we can compare the numbers we just found as well as 0.62. Since our numbers would be 0.625 (5/8), 0.60 (60%), and 0.62, from least to greatest we would get 60%, 0.62, 0.625
Answer:
(A) A scatter plot is used to determine if the linear model is appropriate.
(B) A linear model estimates the value of the dependent variables.
Step-by-step explanation:
The regression model is formed to estimate the Wingspan using the bird's Height when perched.
The model is of the form:
(A)
The <em>R</em> squared value is a statistic that is used to determine the proportion of variation in the dependent variable that can be explained by the independent variables.
<em>R</em> squared value of 93% indicates that 93% variation in the Wingspan is explained y the bird's height when perched.
To determine whether the linear model is appropriate one could use a scatter plot. A scatter plot is used to determine whether the provided data is representing the linear relation between two variables.
(B)
The regression model is:
This model is used to estimate the wingspan for any provided bird's height.
It does provided an accurate value of the dependent variable.
Thus, a bird with height 10 inches can have an estimated wingspan of 17 inches.

Answer:
7 1/3 hours
Step-by-step explanation:
We are to assume that the total number of heater-hours required is a constant. That is, the time is inversely proportional to the number of heaters.
If the number of heaters goes up by a factor of 6/4 = 3/2, then the number of hours will go down by the inverse factor: 2/3.
With 6 heaters instead of 4, the time required is (2/3)(11 hours) = 7 1/3 hours.
