Sally ⇒
4 hours = 1 room
1 hour = 1/4 of the room
Steve ⇒
9 hours = 1 room
1 hour = 1/9 of the room
Sally + Steve ⇒
1 hour = 1/4 + 1/9 = 9/36 + 4/36 = 13/36
Number of hours needed ⇒
1 ÷ 13/36 = 1 x 36/13 = 36/13 = 2 10/13 hours
Answer: They need 2 10/13 hours.
Answer:
Y ≥ -11
Step-by-step explanation:
You start with y+2≥-9
Subtract the 2 on both sides
That would leave you with the y on the left of the ≥ and -11 on the right, giving you your answer.
Answer:
The probability of assembling the product between 7 to 9 minutes is 0.50.
Step-by-step explanation:
Let <em>X</em> = assembling time for a product.
Since the random variable is defined for time interval the variable <em>X</em> is continuously distributed.
It is provided that the random variable <em>X</em> is Uniformly distributed with parameters <em>a</em> = 6 minutes and <em>b</em> = 10 minutes.
The probability density function of a continuous Uniform distribution is:
Compute the probability of assembling the product between 7 to 9 minutes as follows:
Thus, the probability of assembling the product between 7 to 9 minutes is 0.50.
Parallel lines have the same slope, which in this case is m = 1.
Use the slope-intercept formula here: y = mx + b
becomes 2 = (1)(-6) + b. Then b = 8, and
y = x + 8 (answer)
