A cable is made up of four wires. The breaking strength of each wire is a normally distributed random variable with mean 10 kN a
Bas_tet [7]

Answer:

a) μ =35.858KN

b) median cable strength =36.06KN

Step-by-step explanation:

Let X1, X2, X3, X4 represent the strength of the 4 wires.

We can find the median of the cable strength in minitab as:

Stat - Basic statistics- Display descriptive statistics-variable (C5) -statistics(median) - ok

Median cable strength is 36.06 KN

Therefore the estimate of the mean strength of the cable is 35.858 KN, and the estimate of the median cable strength is 36.06 KN.

What is the inverse of the function f(x) = 9/2 x -5
notka56 [123]

Answer:

Step-by-step explanation:

To find inverse you switch x and y and solve for y.

y = (9/2)x - 5

switching gives

x = (9/2)y - 5

x+5 = (9/2)y

(2/9)(x+5) = y

Best explained and correct answer gets brainliest!

The answer is B because C and D are not true. Angle-Angle theorem does not prove congruency. Hypotenuse-Leg does because having a hypotenuse means that the triangle is a right angle triangle, which means that 2 sides and an angle are congruent in the triangles. By Side-Side-Angle Theorem, the triangles are congruent.
