We use the simple rules of statistics to accept the null hypothesis
68% of the data falls within 1 sd of the mean95% of the data falls within 2 sd of the mean 99% of the data falls within 3 sd of the mean
20 falls between the range of -56 to 56 (from the given 95% c.i.), hence we accept the null hypothesis; else, if the mean falls outside the range, we reject the null hypothesis.
Answer:
first we multiply 2357 x 8870
which resulted in 20906590
then we multiply the resultant with 7809 then the final answer is
163,259,561,310
Answer:
Step-by-step explanation:
A linear equation with two variables may appear in the form of Ax + By = C, and the resulting graph is always a straight line. The equation is more often in the form of y = mx+b, where m is the slope of the line of the corresponding figure and b is its Y-axis intercept, that is, the point where the line meets the Y-axis.
For example, 4x + 2y = 8 is a linear equation because it fits the desired structure. But for graphical and most other purposes, we often write this as y = - 2x + 4.
In this unit, on the basis of this linear equation, the equal sign is changed to the greater than a sign or less than sign, which is a new challenge in the operation of symbols.
The Area of carpet for the given dimension is 72m².
<h3>What is Area of rectangle?</h3>
Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.
Let the width of the room w = x m
and the length, L = 1.5x
Length of carpet + 6 = length of room
2(x-6)+6=1.5x
2x-12+6=1.5x
0.5x=6
x = 6 / 0.5
x = 12
length of room x = 12 m
width of room = 18 m
18-6 by 12-6 = 12 by 6 dimensions of carpet
Area of carpet = 12 X 6=72 m²
Thus, the Area of carpet for the given dimension is 72m².
