Answer:
4 minus a number times three
Answer:3/20
Step-by-step explanation:
Heads=Boy
Tails=Girl
If the first 3 students are boys, all 3 coins must be heads.
Because in 3 of these experiments, the coins all land on heads, and there are 20 experiments completed, 3 out of the 20 experiments are 3 boys; 3/20.
Answer: THIRD OPTION.
Step-by-step explanation:
For this exercise you need to use the formula for calculate the distance between two points. This is:
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Given the following points:
and ![(-3,-5)](https://tex.z-dn.net/?f=%28-3%2C-5%29)
You can identify that:
![x_2=-3\\x_1=5\\\\y_2=-5\\y_1=1](https://tex.z-dn.net/?f=x_2%3D-3%5C%5Cx_1%3D5%5C%5C%5C%5Cy_2%3D-5%5C%5Cy_1%3D1)
Knowing these values, the next step is to substitute them into the equation for calculate the distance between two points and then evaluate.
Therefore, the distance between
and
is:
![d=\sqrt{(-3-5)^2+(-5-1)^2}\\\\d=10](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-3-5%29%5E2%2B%28-5-1%29%5E2%7D%5C%5C%5C%5Cd%3D10)
Answer:
the answer is 2
Step-by-step explanation:
2/3/1/3 were going to take 1/3 multiply it by 2/3 and switch the nume and the deno.
2/3 x 3/1 = 6/3
6/3 = 2
Answer:
The answer is d
Step-by-step explanation:
I graphed it
-b/2a to get the vertex
3x^2-12+9
-(-12)/(2)(3)=2
plug in 2 to the function
12-24+9=-3 which is the y value on the graph
(2,-3) is the vertex
