Answer:
8 hours
Step-by-step explanation:
In this case, the speed would be given by the garbage collection / hour, therefore the two together, that is to say from the sum of both, would be 1/6 the speed and for the small truck it would be 1/24
So to calculate the speed of the big truck it would be:
1/24 + 1 / x = 1/6
1 / x = 1/6 - 1/24
1 / x = 0.125
x = 1 / 0.125
x = 8
Which means that only the big truck would take only 8 hours
If the probability of obtaining success is 0.3 and the value of n is 9 then the probability at the value of x be 3 is 0.3811.
Given that the value of n is 9 and the value of p is 0.3.
We are required to find the probability when the value of x is equal to 3.
Probability is the calculation of chance of happening an event among all the events possible.It lies between 0 and 1.
Probability=Number of items/total items.
Binomial probability is basically the probability of exactly x successes on n repeated trials in an experiment which has two possible outcomes.
=
We have to find the value when n=9, p is 0.3 and r=3.
=
=9!/3!6!*0.027*0.16807
=84*0.00453789
=0.381182
Hence if the probability of obtaining success is 0.3 and the value of n is 9 then the probability at the value of x be 3 is 0.3811.

<h2>
Hello!</h2>
The answer is:
It will take 42.35 minutes to weed the garden together.
<h2>
Why?</h2>
To solve the problem, we need to use the given information about the rate for both Laura and her husband. We know that she can weed the garden in 1 hour and 20 minutes (80 minutes) and her husband can weed it in 1 hour and 30 minutes (90 minutes), so we need to combine both's work and calculate how much time it will take to weed the garden together.
So, calculating we have:
Laura's rate:

Husband's rate:

Now, writing the equation we have:








Hence, we have that it will take 42.35 minutes to weed the garden working together.
Have a nice day!
Answer:
Slope=3/4
Step-by-step explanation:
1) Label all values with x1 y1, x2 y2
Then, plug jn each value into this equation:y2-y1/x2-x1
Remember that negative values will become positive when dealjng with a subtraction sign.
5-(-1)=5+1.
---------------= 6/8
6-(-2)=6+2
After getting 6/8, simplify by the gcf (2) to get 3/4
Answer:3/4
