Answer:
have 6 is large and 4 is medium
Step-by-step explanation:
this is my sloution:
first we can think all 10 packs of cups is large
10*2.40=24 dollars
then we subtract
24-21.60=2.4
after that we subtract large and medium
2.40-1.80=0.6
finally is 2.4/0.6=4
so 4is medium
10-4=6 6 is large
Answer:
Larger number x=54
y=17
Step-by-step explanation:
x+y=71
x-y=37 then x=y+37
substitute x
y+37+y=71
2y=34
y=17
x=y+37=54
Answer:
12a. (-6, -6)
12b. 17
13a. y = x +
13b. 2
Step-by-step explanation:
12a. Using the midpoint formula:
= = (-6, -6)
12b. Using the Distance formula:
d = = = =
= 12 or 17
13a. x + 2y = 3
2y = 3 - x
y = x +
13b. The perpendicular slope is 2
The 95% confidence interval for the slope will be B. (-0.308,-0.019).
<h3>How to calculate the interval?</h3>
The confidence interval based on the information and diagram will be:
= -0.1636 + 2.228 × 0.06488
= 0.019
Also, -0.1636 - 2.228 × 0.06488
= -0.308
In conclusion, the correct option is (-0.308,-0.019).

Answer:
Step-by-step explanation:
Presuming represents the length of the box (which you should have specified), your volume function:
is correct.
V(x)=-x^3+33x^2-90x=0
Obviously, in order to have a box, all three dimensions must be positive numbers.
Since the height is 3 less than the length, the length must be greater than 3 so that the height will be greater than zero. Since the sum of length and width is 30, the length must be less than 30. Hence, the possible range of values for is
If you know enough calculus to be able to take the derivative of this function, set the first derivative equal to zero and solve. You will obtain two possible extrema. Only one of these extrema will lie in the the acceptable range of values,
If you don't know the Calculus, then the best you can do is to graph the function and eyeball it.
