For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut point with the y axis
According to the graph, we have the points:
We find the slope:
Thus, the equation is of the form:
We substitute a point and find b:
Finally we have:
Answer:
Answer:
To be able to determine the unknown range of the number with tolerance given, first we need to determine the 4% of 500. This can be done by multiplying 500 by the decimal equivalent of 4% which is equal to 0.04.
tolerance = (500) x (0.04) = 20
Lower limit: The lower limit is determined by subtracting 20 from 500.
Lower limit = 500 - 20 = 480
Upper limit: The upper limit is determined by adding 20 to the base value 500.
Upper limit = 500 + 20 = 520
The values, therefore, rang from 480 to 500.
<em>ANSWER: 480 - 520</em>

Hello!
If you want to test if the proportion of females is the same for five groups, the test you use is a Chi-Square test for homogeneity wherein the null hypothesis you have to state that the proportion of females is the same in the five groups vs the alternative hypothesis were you state that at least one of the female proportions is different from the rest.
The Statistic is
~
Being r is the number of rows and c is the number of columns. (let's say the information is in a contingency table where: in the rows is the information of the gender "female" and "male" and in the columns are the five groups, so you have 2 rows and 5 columns)
Remember that the critical region for this test is always one-tailed to the right, meaning, that you will reject the null hypothesis when the difference between the observed frequencies and the expected frequencies is big. So the critical region is:
X² ≥ X²
The degrees of freedom are: (2-1)*(5-1) = 4

Answer:
Depth is 4 feet.
Step-by-step explanation:
Given:
Length of an aquarium is 2.3 feet
Width of an aquarium is 1.2 feet
Volume of an an aquarium is 11.04 cubic feet
To find: depth of an aquarium is 2.3 feet
Solution:
If denote length, width and height of a cuboid then volume (V) of a cuboid is equal to
feet
feet
cubic feet
feet
Therefore,
depth is 4 feet.
