Answer:
The answer is D.
Step-by-step explanation:
We have to apply Discriminant Law. When a quadratic equation, ax² + bx + c = 0 has equal roots so the discriminant will be 0. Then, you have to substitute the values into the formula :
![D = {b}^{2} - 4ac](https://tex.z-dn.net/?f=D%20%3D%20%20%7Bb%7D%5E%7B2%7D%20%20-%204ac)
![let \: D = 0 ,a = 2,b = k,c = k](https://tex.z-dn.net/?f=let%20%20%20%5C%3A%20D%20%3D%200%20%2Ca%20%3D%202%2Cb%20%3D%20k%2Cc%20%3D%20k)
![0 = {k}^{2} - 4(2)(k)](https://tex.z-dn.net/?f=0%20%3D%20%20%7Bk%7D%5E%7B2%7D%20%20-%204%282%29%28k%29)
![{k}^{2} - 8k = 0](https://tex.z-dn.net/?f=%20%7Bk%7D%5E%7B2%7D%20%20-%208k%20%3D%200)
![k(k - 8) = 0](https://tex.z-dn.net/?f=k%28k%20-%208%29%20%3D%200)
![k = 0](https://tex.z-dn.net/?f=k%20%3D%200)
![k - 8 = 0](https://tex.z-dn.net/?f=k%20-%208%20%3D%200)
![k = 8](https://tex.z-dn.net/?f=k%20%3D%208)
Answer:
Step-by-step explanation:
Okay, I'm assuming you want us to figure out how much the hat costs.
To start off, let's figure out how much the gloves cost after the discount. 35 / 100= 0.3. We multiply that by 70%, since that is how much of the price is going to be left over after deducting 30%. We get $24.50.
So;
$44.80 of the total bill - $24.50=$20.30.
So we now know the hat cost $20.30.
if you're looking for someone to double-check I just did and you're right.
The probability that both grab oranges would be = ![\frac{1}{36}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B36%7D)
Step-by-step explanation:
Given,
A bowl contains,
Apples = a = 5
Oranges = o = 2
bananas = b = 2
Total fruits in bowl = x = a + o + b = 5 + 2 + 2 = 9
Now, Christian and Aaron come home from school and randomly grab one fruit each.
The probability of first selecting orange would be = ![\frac{o}{b} = \frac{2}{9}](https://tex.z-dn.net/?f=%5Cfrac%7Bo%7D%7Bb%7D%20%3D%20%5Cfrac%7B2%7D%7B9%7D)
Now, the oranges left would be 2 - 1 = 1
and total fruits would be = 9 - 1 = 8
Hence, the probability of selecting second orange would be = ![\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D)
Therefore, the probability that both grab oranges would be = ![\frac{1}{8} * \frac{2}{9} = \frac{1}{36}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D%20%2A%20%5Cfrac%7B2%7D%7B9%7D%20%3D%20%5Cfrac%7B1%7D%7B36%7D)
