An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 160 engines
abruzzese [7]

Answer:

Test statistic   Z = 2.1097

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that size of the sample 'n' = 160

Given that mean of the Population(μ)  = 5.3pounds/square inch

The Standard deviation of the population(σ) = 0.6

Mean of the sample(x⁻) = 5.4

Level of significance =0.1

<u><em>Step(ii):-</em></u>

Test statistic

    Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }

   Z = \frac{5.4-5.3}{\frac{0.6}{\sqrt{160} } }

  Z = 2.1097

<u><em>Final answer</em></u>:-

Test statistic   Z = 2.1097

Triangle A″B″C″ is formed using the translation (x + 0, y + 2) and the dilation by a scale factor of 2 from the origin. Which eq
garik1379 [7]

Answer:

segment AC is equal to A''B'' over 2

Step-by-step explanation:

Given that,

Scale factor = 2

The coordinates of A is (-3,3)

The coordinates of B is (1,-3)

The coordinates of C is (-3,3)

We know that, the ratio of length of new segment to the length of segment of original figure is called scale factor.

So.

\dfrac{A''B''}{AC}=2\\\\\text{On cross multiplying,}\\\\AC=\dfrac{A''B''}{2}

It means, segment AC is equal to A''B'' over 2 is the correct answer.

Given z1 and z2, what is the midpoint?<br><br> z1=5-7i and z2=-9+3i.
sveta [45]

Answer:

7-2i

Step-by-step explanation:

As you're used to do in the real plane, midpoint is the average of Real and Imaginary part. So \frac{5+9}2 +i \frac{-7+3}2 = \frac{14}2+i\frac{-4}2 = 7-2i
