Y = -0.4x
1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °
With all that information you can identify the graph, given that you didn't include the options.
Answer:
2 x 10^6
Step-by-step explanation:
10^6 = 1,000,000
2 x 1,000,000 = 2,000,000
10^5 = 100,000
9 x 100,000 = 900,000
2,000,000 > 900,000
The angle sum property of a triangle is the sum of the interior angles of the given triangle.
The total sum of the interior angels of a triangle =180
V= 3.14• 5^2•4
V= 3.14 •25•4
V= 78.5•4
V=314
Sorry I couldn’t give a more detailed explanation but here is the original equation for volume of a cylinder:
V=πr2h

Answer: t = 1.9287
Step-by-step explanation:
Let
be the average number of pages should be sent by 2-day mail instead.
As per given we have,

Sample mean : 
Sample standard deviation : s=3.81
sample size : n= 24
Since , the sample size is less than 30 and populations standard deviation is unknown , so we use t-test.
The test statistic for population mean :-


Hence, the test statistics : t = 1.9287
