Answer:
I=\frac{t^2}{2}
Step-by-step explanation:
From exercise we have that x=t, t>0. Because A(t) be the area of the region in the first quadrant, we get that x started at 0. The limits for y are the following e-x and e. We get the integral :
I=\int\limits^0_t \int\limits^{e}_{e-x} 1 dy dx
I=\int\limits^0_t [y]_{e-x}^{e} dx
I=\int\limits^0_t (e-e+x) dx
I=\int\limits^0_t {x} \, dx
I=[\frac{x^2}{2} ]_{0}^{t}
I=\frac{t^2}{2}
Answer:40
Step-by-step explanation:
their is 3 type of cheese and he buy 120
120/3=40
Answer:
t=5.25x
Step-by-step explanation:
since X equals the number of egg cartons sold then we would have to multiply that by how much one egg carton costs (5.25$ each)
so if they sold 3 egg cartons the equation would be t=5.25*3.
(putting a variable next to a number means your multiplying it)
I hope I explained that clearly enough :P
50% of the data values are greater than 45, it is calculated using the concept of box-whisker plot.
In a box-whisker plot as shown it is given in the picture ,
A rectangular shaped box with two lines with a vertical mark which denotes the minimum, first quartile, median , third quartile and maximum quartile.
It is used in descriptive statistics.
So as per the given question box-whisker plot represents some data set .There is a number 45 just corresponding to it there is a vertical line which shows that 45 is the median of the data and here 45 is the 50th percentile,
It means that there is 50 % values are greater than 45 and 50% values are greater than 45.
By this method we can quickly find out the percentage of data for which data the value is greater or lesser. It helps in analyzing the data and interpreting the results.
Hence 50% values are greater than 45.
