Answer:
Mean = 15
Standard deviation = 1.94
Step-by-step explanation:
We are given the following information:
We treat favoring of building a police substation as a success.
P(Success) = 75% = 0.75
Then the number of citizens follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 20
We have to find the mean and the standard deviation.
Thus, the mean of favoring the substation is 15 and the standard deviation of favoring substation is 1.94
Answer:
x 1 2 6 12 25
f(x) 22 34 82 154 310
f(3)= 46 means that in the third month, the online magazine provider will charge a total of $46.00
Step-by-step explanation:
For finding the missing f(x) values:
Plug in the x-values that are given into the original equation: f(x)= 12x + 10
ex: f(1)= 12(1) + 10 => 22
For finding the missing x value, set the original equation to the given f(x) value
ex: 34 = 12x + 10 => 2
Okay so you need to write down all of your original points, for example:
<A (1,1)
<B (3,4)
<C (5,1)
so now for each of those coordinates you would subtract four from each X and add 3 to each Y. For example:
Original Cord.: Translated Cord.:
<A (1,1) <A' (-3,4)
<B (3,4) <B' (-1,6)
<C (5,1) <C' (2, 4)
------------------------------------------------------------------------
So just follow my steps but with your points, then graph both the original coordinates and the translated coordinates. AND DON'T FORGET TO LABEL THE POINTS LIKE I DID WHEN GRAPHING!!!!!!!!
Answer:
260 centimetres
Step-by-step explanation:
Answer:
The circumference of original circle is, The area of original circle is, The dilation by scale factor 8 means the radius of new circle is 8 times of the original circle. Therefore the radius of new circle is 4 ft and the statement A is true.
