Benone would finish mower garden in 8 hours. Pandele would finish in 10 hours mowing same garden. How long would finish mower garden together?

Answers

Answer 1

Answer: $Benone-(1)/(8)\ mower\ garden\ per\ hour\n\nPandele-(1)/(10)\ mower\ garden\ per\ hour\n\n(1)/(8)+(1)/(10)=(*)\n\nfind\ LCD((1)/(8);\ (1)/(10))\n\nList\ of\ the\ multiples\ of\ 8:0;\ 8;\ 16;\ 24;\ 32;\ \boxed{40};\ 48;...\nList\ of\ the\ multiples\ of\ 10:0;\ 10;\ 20;\ 30;\ \boxed{40};\ 50;\ ...\n\nLCD((1)/(8);\ (1)/(10))=40\n\n(1)/(8)=(1\cdot5)/(8\cdot5)=(5)/(40);\ (1)/(10)=(1\cdot4)/(10\cdot4)=(4)/(40)$

$(*)=(5)/(40)+(4)/(40)=(9)/(40)-together\ per\ hour$

$t-time\ when\ together\ finish\ the\ garden\n\n(9)/(40)\cdot t=1\ \ \ \ \ \ |multiply\ both\ sides\ by\ (40)/(9)\n\n\boxed{t=(40)/(9)\ (h)=4(4)/(9)\ h=4h+(4)/(9)h=4h+(4)/(9)h=4h+(4)/(9)\cdot60\ min\approx4h27min}$

Answer 2

Answer: In 1 hour, Benone _ _ _ g / 8 ;
In 1 hour, Pandele _ _ _ g / 10 ;
= = = = = = = = = = = = = = = = =
In 1 hour, Benone and Pandele _ _ _ g / 8 + g / 10 = 5g / 40 + 4g / 40 = 9g / 40;
Benone and Pandele would finish garden together in 40 / 9 hours = 4 hours 26 minutes 40 seconds;

A manufacturing process is designed to produce bolts with a 0.75-inch diameter. Once each day, a random sample of 36 bolts is selected and the bolt diameters recorded. If the resulting sample mean is less than 0.730 inches or greater than 0.770 inches, the process is shut down for adjustment. The standard deviation for diameter is 0.04 inches. What is the probability that the manufacturing line will be shut down unnecessarily? (Hint: Find the probability of observing an x in the shutdown range when the true process mean really is 0.75 inches. Round your answer to four decimal places.)

Fill in the blank. A _______ probability of an event is a probability obtained with knowledge that some other event has already occurred.

Answers

Answer:

A conditional probability of an event is a probability obtained with knowledge that some other event has already occurred.

Step-by-step explanation:

Conditional probability of an event (A) is a probability obtained with knowledge that some other event (B) has already occurred and is denoted as P(A|B).

It satisfies the following equation:

P(A|B)=P(A and B) / P(B)

where P(A and B) is the probability of A and B occurring together.

Conditional probability is applied in many areas of Bayesian statistics and machine learning.

Final answer:

The blank space should be filled with 'conditional'. A conditional probability of an event is a probability calculated with the knowledge that another event has already happened.

Explanation:

The blank space should be filled with 'conditional'. A conditional probability of an event is a probability obtained with knowledge that some other event has already occurred. Suppose you have events A and B from the same sample space. The conditional probability of event A given that event B has occurred, denoted as P(A|B), is computed as P(A and B) divided by P(B), where P(A and B) represents the probability that both events happen, and P(B) is the probability of B happening. This quantity is meaningful as long as P(B) is not zero.
