Answer:
7 hours
Step-by-step explanation:
Answer:
The new number would have to be 6.
Step-by-step explanation:
In order to find the mean you add all numbers and divide by how many numbers you added together. In this case you would add 3, 5, 7, and 9 and divide by 4 to get 6. If the median of the cards is still six you could multiply 6 and 5 because you have 5 numbers. Then subtract 9, 7, 5, and 3 which will give you six.
Answer:
D
Step-by-step explanation:
in this case it is easier to take out the decimal place holder
132>102
132>123
132>131
132<138
The only one that is greater than 1.32 is D and that is only by a very small amount.
Answer:
y = (x - 2)^2 + 1
Step-by-step explanation:
The general equation of a parabola in vertex form is y-k = (x-h)^2. Here, we can see immediately from the graph that the vertex is at (2, 1). Thus, the equation of this particular parabola takes the form y - 1 = a(x - 2)^2. We must still determine the value of a. Note that the graph goes through (0, 5). Thus, 5 - 1 = a(0 - 2)^2, or
4 = 4a. Thus, a = 1, and the equation of this parabola is y - 1 = (x - 2)^2, or, after simplification, y = (x - 2)^2 + 1.
Answer:
40 mph
Step-by-step explanation:
Recall that the slope of this line is also the speed at which the car was driven, and that, in turn, is:
240 miles
------------------- = 40 mph
