Answer: You need to grap a square where each side has 10 units in the grid.
Step-by-step explanation:
We know that each square has a side lenght of 0.1mm
Each unit in the grid represents 0.01mm
Then 10 units in the grid will represent 10*0.01 mm = 0.1mm.
Then the square face will be writen a square with a lenght of 10 units.
The question is incomplete. The complete question is :
The breaking strengths of cables produced by a certain manufacturer have a mean of 1900 pounds, and a standard deviation of 65 pounds. It is claimed that an improvement in the manufacturing process has increased the mean breaking strength. To evaluate this claim, 150 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1902 pounds. Assume that the population is normally distributed. Can we support, at the 0.01 level of significance, the claim that the mean breaking strength has increased?
Solution :
Given data :
Mean, μ = 1900
Standard deviation, σ = 65
Sample size, n = 150
Sample mean,
= 1902
Level of significance = 0.01
The hypothesis are :


Test statics :
We use the z test as the sample size is large and we know the population standard deviation.




Finding the p-value:
P-value = P(Z > z)
= P(Z > 0.38)
= 1 - P(Z < 0.38)
From the z table. we get
P(Z < 0.38) = 0.6480
Therefore,
P-value = 1 - P(Z < 0.38)
= 1 - 0.6480
= 0.3520
Decision :
If the p value is less than 0.01, then we reject the
, otherwise we fail to reject
.
Since the value of p = 0.3520 > 0.01, the level of significance, then we fail to reject
.
Conclusion :
At a significance level of 0.01, we have no sufficient evidence to support that the mean breaking strength has increased.
Given system:
-2x-y=1 ....................(1)
-4x-2y=-1 ..................(2)
2*(1) -(2)
-4x-2y +4x+2y = 2-(-1)
0=3 => there is no solution because the two lines (equations) are parallel and distinct (never meet), so no solution.

Due to the inclination of the
terrestrial axis, the day has different duration in several points of the
planet, which also depends on the time of year. However, this duration remains the same throughout the year in the Equator,
which is known as the imaginary line that divides the planet in two
hemispheres: Northern Hemisphere and Southern Hemisphere.
