Answer:
55 = 5 × 11
Step-by-step explanation:
The only prime factors of 55 are 5 and 11, thus
55 = 5 × 11
Answer:
<em>The side length of the new square is 24 ft.</em>
Step-by-step explanation:
<u>Dilations</u>
A dilation is a transformation that produces a new image that is the same shape as the original but of a different size.
A dilation stretches or shrinks the original figure. To describe a dilation it's usually included the scale factor (or ratio) and the center of the dilation.
We have a square with a side length of 36 ft. When this square is dilated by a scale factor of 2/3, the new square will have a side length of 36*2/3= 24 ft.
The side length of the new square is 24 ft.
Answer:The third graph (left of the bottom) represents over the domain 3≤x≤6.
Step-by-step explanation:
The Least Interger Function is represented by .
The least integer function is a discontinuous function whose value at any number x is the smallest integer greater than of equal to x .It is denoted by .and It is also known as ceiling of x. For example
So the third graph (left of the bottom) represents over the domain 3≤x≤6.
[we can see all the value of x starting from 3 pointed at y=3 and for x≤ 4 are converging to y=4 which is represented by solid dot and so on ... ]
Hope this helps (Copied from the same question from someone else)
Answer:
We can say at 99% confidence that the true mean is between (91.674;98.326)
Step-by-step explanation:
Data given
represent the sample mean
population mean (variable of interest)
s=6.6 represent the sample standard deviation
n=30 represent the sample size
The confidence interval for the mean is given by the following formula:
(1)
We need to find the critical value and we need to find first the degrees of freedom, given by:
Since the Confidence is 0.99 or 99%, the value of and , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.005,29)".And we see that
And replacing we got:
We can say at 99% confidence that the true mean is between (91.674;98.326)
