Answer:
5.2y^3
Step-by-step explanation:
There are 3 y's which can be presented as y^3
5.2 times y^3 = 5.2y^3
( By the way, " ^ " is a square root sign )
Answer:
The proportions of the diameters that are greater than 25.4 millimeters is 5%.
Step-by-step explanation:
Given;
mean of the normal distribution, m = 25.1 millimeters
standard deviation, d = 0.08 millimeter
1 standard deviation above the mean = m + d = 25.1 + 0.08 = 25.18
2 standard deviation above mean = m + 2d = 25.1 + 2(0.08) = 25.26
3 standard deviation above the mean = m + 3d = 25.1 + 3(0.08) = 25.34
4 standard deviation above the mean = m + 4d = 25.1 + 4(0.08) = 25.42
To obtain a diameter greater than 25.4, we select data after 4 standard deviation above the mean.
Data within 4 standard deviation above the mean is 95%
Data outside 4 standard deviation above the mean is 5%
Therefore, the proportions of the diameters that are greater than 25.4 millimeters is 5%.

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have two points through which the line passes:
We found the slope:
The slope is zero.
Thus, the equation is of the form:
We substitute one of the points and find b:
Finally, the equation is:
Answer:
Answer:
ok so orders of operation.
Step-by-step explanation:
parenthesis,brachets: 2{3[9+4(2)-4]}
2{3[13×2-4]}
then we take whats inside the brackets and use order of operations there
13×2-4
parenthesis:none
exponents:none
multiplication: 13×2=26
division:none
addition: none
subtraction:26-4=22
then you're left with the equation:
2{3[26]}
clearly we aren't done with the brackets
so we do:
3×26=78
we're left with:
2{78}=156
your answer=156
