Answer:
The vertex would be (1, -7/10)
Step-by-step explanation:
In order to find the vertex, start by finding the x-coordinate. The x-coordinate can be calculated using -b/2a, in which a is the coefficient of x^2 and b is the coefficient of x.
-b/2a
-(-2)/2(1)
2/2
1
Now that we know the value of the x-coordinate as 1, we can use it in the equation to find y.
y = x^2 - 2x + 3/10
y = (1)^2 - 2(1) + 3/10
y = 1 - 2 + 3/10
y = -7/10
Answer:
25.
Step-by-step explanation:
5 ft 7 in = 5.583 ft.
We have 2 similar triangles here.
If h is the height of the tree, then:
h / 5.583 = 18/4
h = 18*5.583/4
h = 25.12 ft

The probability of picking a red face card from the deck is ![(\frac{3}{26} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B3%7D%7B26%7D%20%29)

The probability of NOT picking a red face card from the deck is ![(\frac{23}{26} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B23%7D%7B26%7D%20%29)
</h3>
Step-by-step explanation:
The total number of cards in the deck = 52
The total number of red( Diamond + Hearts) face cards in the given deck
= 2 Red Queens + 2 Red jacks + 2 Red kings = 6 cards
Let E : Event of picking a red face card from the deck
Now , P( any event) = ![\frac{\textrm{The number of favorable observations}}{\textrm{Total number of observations}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctextrm%7BThe%20number%20of%20favorable%20observations%7D%7D%7B%5Ctextrm%7BTotal%20number%20of%20observations%7D%7D)
So, here P(Picking a red face card) = ![\frac{\textrm{The number of red face cards}}{\textrm{Total number of cards}} = (\frac{6}{52} ) = (\frac{3}{26})](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctextrm%7BThe%20number%20of%20red%20face%20cards%7D%7D%7B%5Ctextrm%7BTotal%20number%20of%20cards%7D%7D%20%3D%20%20%28%5Cfrac%7B6%7D%7B52%7D%20%29%20%3D%20%28%5Cfrac%7B3%7D%7B26%7D%29)
Hence, the probability of picking a red face card from the deck is ![(\frac{3}{26} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B3%7D%7B26%7D%20%29)
Now, as we know P (any event NOT A) = 1 - P(any event A)
So, P(NOT Picking a red face card) = 1 - P(Picking a red face card)
Hence, the probability of NOT picking a red face card from the deck is ![(\frac{23}{26} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B23%7D%7B26%7D%20%29)
