To find the median, place the given numbers in order of their value and find the middle number.
Here we have:
57, 61, 58, 54, 68, 51, 49, 64, 50, 48, 65, 52, 56, 46, 47, 55, 42, 60, 62, 43, 69, and 70.
Arranging them in order from least to greatest, we have:
42, 43, 46, 47, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 61, 62, 64, 65, 68, 69, and 70.
There are 22 numbers total; the median will be the mean of the middle two numbers, which are 55 and 56.
To find the mean, add the numbers together and divide the sum by 2.
55 + 56 = 111
111 / 2 = 55.5
The median of the ages of the US Presidents at the time of their inauguration is 55.5 years.
The graph of f(x) = (0.5)^x is replaced by the graph of g(x) = (0.5)^x − k. If g(x) is obtained by shifting f(x) down by 2 units, the value of k is 2 because g(x)=(.5)x-2. g(x) is f(x) without the "shift" and it said the shift was 2 units, so k is 2
Answer:
x = -11
Step-by-step explanation:
5x + 2 = 4x - 9
-2 -2
5x = 4x - 11
-4x -4x
x = -11
The value of t is 3/2 or 1.5
<u>Step-by-step explanation</u>:
The given expression is 17/20 equals t plus -13/20.
<u>Changing it into an equation form :</u>
⇒ t + (-13/20) = 17/20
Keeping t alone on one side and constant terms to the another side,
t = (17/20) + (13/20)
Since the denominators are same, it is easy to simplify those fractions.
⇒ t = (17+13)/20
⇒ t = 30/20
⇒ t = 3/2
⇒ t = 1.5
The solution is t= 3/2 or t= 1.5
Answer:
(3, 3 )
Step-by-step explanation:
Given
y = 4x - 9 and that x = 3 is part of the solution, then
y = 4(3) - 9 = 12 - 9 = 3 ← missing value in the solution
solution is (3, 3 )
