ANSWER

The number of children between the ages of 9 and 15 who visited the park is
20


EXPLANATION


The number of children between the ages of 9 and 15 who visited the park are those within the age group 9 to 12 and 12 to 15.


We can from the graph that, the height of the bar that corresponds to the age group 9 to 12

= 14
and the height of the bar that corresponds to the age group 12 to 15

= 6


The sum of the two frequencies

= 14 + 6 = 20

How do I factor e^2-10e+25
olga nikolaevna [1]

Answer: (e-5)^2

Step-by-step explanation:

The box method is a good way to solve this, but for a quick explanation, start by finding a single value that when added gets -10 and when multiplied gets +25. We can find that this term is -5. We the can situate -5 into (e-5)^2 equation, where if you FOIL, you will be back at the unfactored equation. Hope this helps

Find all zeros of <br>f(x)= x^3 + 3x^2 − 3x − 1
PSYCHO15rus [73]
F(1) =  1^3 + 3(1)^1 - 3 - 1 = 1 + 3 - 3 - 1 = 0

so one zero  is x = 1, and x-1 is a factor

dividing f(x)  by x - 1 gives x^2 + 4x + 1

x = [-4 +/- sqrt (16 - 4)] /  2

x = -0.27, -3.73

zeroes are 1 , -0.27 and -3.73   Answer
