Answer:
11 oz
Step-by-step explanation:
11 ounces for each hamburger patty
explanation:
1 pound(lbs) = 16 ounces(oz)
Convert 5lbs into ounces
5x16 = 80oz
80 + 8 = 88 Add all the ounces together
/8 = Divide by 8 people
11oz each
6eggs/7days= 0.857 eggs/day
Answer:
See below.
Step-by-step explanation:
f(x) = -25x2 + 30x − 9
This is a parabola which opens downwards.
Part A.
The discriminant b^2 - 4ac = 30^2 - 4*(-25) * -9
= 900 - 900
= 0
This indicates that the graph of the function just touches the x-axis. So there is one root of multiplicity 2.
Factoring:
-25x2 + 30x − 9
= -(25x^2 - 30x + 9)
= -(5x - 3)(5x - 3)
so the roots are x = 3/5 multiplicity 2.
The x -intercept is at (0.6, 0).
Part B.
The y intercept is when x = 0 so here it is
y = -25(0)^2 + 30(0) -9
= -9
The constant at the end of the function (-9) indicates the y-intercept.
The y intercept is at (0, -9).
Part C.
The end behaviour of f(x):
The negative coefficient (-25) of x^2 indicates that the graph increases from negative infinity from the left.
Since it is a parabola that opens downwards ( because of the -25) it decreases to negative infinity on the right.
Answer:
a) 0.3889
b) 0.5
c) 0.8333
d) The mean is 250 and the standard deviation is 51.96.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability of finding a value of X higher than x is:
The probability of finding a value of X between c and d is:
The mean and the standard deviation are, respectively:
A random variable follows the continuous uniform distribution between 160 and 340.
This means that 
a)
b)
c)
d)
The mean is 250 and the standard deviation is 51.96.
2.89 x 23.2
289 x 232 = 67048
