A fatigue test is performed on 85 rotating beam specimens made of 5160H steel, where the specimens are subject to a cyclic load that causes tensile and compressive stresses of equal magnitude. The number of cycles to failure for this population of specimens follows a Gaussian distribution with mean 130 cycles and standard deviation of 50 cycles. a) What is the probabilty that a specimen would fail at 95 cycles or less

d) 48

step-by-step explanation:

16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304,320,336

345

step-by-step explanation:

6 meters

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
