Answer:
The point estimate for the mean endowment of all private colleges in the United States is 180.2125 million dollars.
Step-by-step explanation:
We are given endowments (in millions of dollars) of eight private colleges in the United States:
78.8, 50.3, 243.2, 489, 111.5, 163.7, 92.4, 212.8
We have to find the point estimate of the population mean endowment of all private colleges in the United States.
The point estimate will be given by the sample mean.
Formula:
Thus, the point estimate is 180.2125 million dollars.
Answer:
A dot plot is like a histogram but it uses dots instead of bars. Like histogram, a dot plot also presents the frequency of data points. The dot plot as described by the problem is shown in the picture. A bell shape is drawn for a symmetrical data. From the choices, the answer is: It is symmetric and has no gaps. The other statements are wrong because the peak is at $5 or $6.
6.8/5 = 1.36
1.36 x 8 = 10.88
This means that the cost of an adult is $10.88
Answer:
6x^2+2x-6
Step-by-step explanation:
In the expression (2x)(x2)+(2x)(x)+(2x)(-2)+(3)(x2)+(3)(-2) take each set of two and solve those individually. The expression then becomes 4x^2+2x^2-4x+6x-6 the combining like terms you get 6x^2+2x-6.
Answer:
Yes
Step-by-step explanation:
