A machine shop produces heavy duty high endurance 20-inch rods that are meant for use in a variety of military grade equipment.

On occasion, the machine malfunctions and produces a groove or a chisel cut mark somewhere on the rod. If such defective rods can be cut so that there is at least 15 consecutive inches without a groove, then the rods can be salvaged for other purposes. If the location of the groove on a rod is described by a uniform distribution, what is the probability that a defective rod can be salvaged?

The likelihood of salvaging a defective rod is 0.50. Given that the machine shop creates heavy-duty 20-inch rods, occasionally, defects occur from grooves or chisel cuts. If these defective rods can be cut such that at least 15 inches remain unblemished, these rods can be salvaged if the groove is located anywhere from 0 to 5 inches on the rod (20 - 15). Thus: P(X ≤ 5) = 0.25 and P(X ≥ 15) = 0.25. The probability of salvaging a defective rod equals P(X ≤ 5) + P(X ≥ 15) = 0.25 + 0.25 = 0.50.

Zina [11989]
Assuming that the departure day for both is day 0, Sandy's next day off occurs on day 4, while Morgan's falls on day 10. Sandy's days off will be on days 4, 8, 12, 16, and 20. Meanwhile, Morgan's days off will be on days 10, 20, 30, 40, and 50. Thus, both of them will share a day off on day 20, meaning they will next have a joint day off in 20 days.

mridul jogs around a rectangular park of 100m by 80m at the rate of 9km per hour. how much time will he take in jogging 6 rounds
tester [11900]
14 minutes. Step-by-step explanation: First, find the perimeter which can be calculated as P=100+80+100+80 = 360 meters, and then multiply it by 6 for the total distance = 2160 meters. To convert meters to kilometers, note that 1000 m = 1 km, so you would find how many kilometers are in 2160 m by cross-multiplying to get 2.16 km. Lastly, you need to calculate the time required represented by T = D/S = 2.16 km / 9 km/h, which simplifies down and gives you the time.

While on vacation in Canada, you notice that temperatures are reported in degrees Celsius. You know there is a linear
zzz [11820]

Given that the relationship is linear.

The equation can be expressed as y = mx + c.

Substituting, when x = 0, we have y = 32.

Thus, 32 = c.......( 1 )

Then, when x = 100, y results in 212.

Which gives us:

212 = 100m + c.......( 2 )

By equating equations 1 and 2, we obtain:

100m = 212 - 32

Solving for x yields 1.8.

The final equation is therefore y = 1.8x + 32.

Hence, this represents the required solution.

A species of horned beetle has a (starting) population size of 4000 individuals. Every month, 170 individuals are born. However,
babunello [11306]

Answer:

Please refer to the explanation

Step-by-step explanation:

Provided parameters:

Initial population = 4000

Monthly increase = 170

Monthly decline in population = 70

Monthly growth rate in population (dt):

Starting population = 4000

Births per month = 170

However, there is a loss of 70 individuals monthly

Thus,

Births - Deaths (d) = 70

170 - d = - 70 (is there a decline?

170 + 70 = d

d equals the number of deaths

Per capita death rate:

Total deaths monthly / Initial population

= 240 / 4000

= 0.06

If m<BEG = (19x + 3)° and m<EGC = (m<GCB + 4x)°, which of the following statements is true about quadrilateral BEGC? Se
Inessa [12141]

Answer:

The total of all exterior angles in BEGC equals 360° ⇒ only answer F is correct

Step-by-step explanation:

* Let’s review some basics regarding quadrilaterals

- A quadrilateral is a polygon that has four sides

- The interior angles of any quadrilateral add up to 360°

- The exterior angles of any quadrilateral also total 360°

* Now let’s tackle the problem

- DEGC is indeed a quadrilateral

∵ m∠BEG = (19x + 3)°

∵ m∠EGC = (m∠GCB + 4x)°

∵ The total of the interior angles measures 360°

∴ m∠BEG + m∠EGC + m∠GCB + m∠CBE = 360

∴ (19x + 3) + (m∠GCB + 4x) + m∠GCB + m∠CBE = 360 ⇒ combine like terms

∴ (19x + 4x) + (m∠GCB + m∠GCB) + m∠CBE + 3 = 360 ⇒ subtract 3 from both sides

∴ 23x + 2m∠GCB + m∠CBE = 375

∵ The exterior angles of any quadrilateral will always sum to 360°

∴ Only the statement in answer F holds true
