I think the answer varies, depending on how the question is worded.
Here's how I got it:
In PEMDAS, you must do the work in parenthesis first. 60 plus 7 is 67, and 4 times 67 is 268, so there are a variety of answers.
You could do 200 + (60+8), and the answer would be 268.
You could do 100 + (110+58), and the answer would be 268.
You could even do 1 + (200+{60 + [4+4] } ), and the answer would be 268.
It depends on what the answer choices are, really. If it isn't an answer choice question, you got three answers right off the bat.
Answer:
5/126
Step-by-step explanation:
Let's go through this scenario step-by-step. At the beginning, we have a 5/9 possibility of picking a boy - 5 boys out of 9 students. If we pick 1 boy, we now have 4 boys out of 8 students we could potentially pick, giving us a 4/8 or 1/2 chance of picking a second boy after the 1st. For the third boy, we have 3 out of 7 remaining students, giving us a 3/7 chance of picking a third after the first two, and for the fourth boy, we 2 possibilities out of 6, giving us a 2/6 or 1/3 chance of picking the 4 boys.
To find the total probability, we can multiply all of these individual ones together:
![\frac{5}{9} \cdot\frac{1}{2} \cdot\frac{3}{7} \cdot\frac{1}{3}\\\\=\frac{5}{9} \cdot\frac{1}{2} \cdot\frac{1}{7}\\\\=\frac{5}{126}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B9%7D%20%5Ccdot%5Cfrac%7B1%7D%7B2%7D%20%5Ccdot%5Cfrac%7B3%7D%7B7%7D%20%5Ccdot%5Cfrac%7B1%7D%7B3%7D%5C%5C%5C%5C%3D%5Cfrac%7B5%7D%7B9%7D%20%5Ccdot%5Cfrac%7B1%7D%7B2%7D%20%5Ccdot%5Cfrac%7B1%7D%7B7%7D%5C%5C%5C%5C%3D%5Cfrac%7B5%7D%7B126%7D)
Answer:
One solution
Step-by-step explanation:
Answer: Hello!
we have the function f(x) = IxI, and we want to write the formula if the function where we have the graph of f(x) translated left by 4 units.
Let's think it:
the graph of f(x) is like a V, where the vertix is at x = 0, then a translation to the left by 4 units mean that now the vertix is at x = -4, then in the new function, we have g( x = -4) = f(0)
This means that now we have
y = g(x) = f( x + 4) = Ix+4I
Always when you want a translation left by N units for the graph of f(x), you need to do:
y = g(x) = f( x +N)
and if the translation is to the right:
y = h(x) = f(x - N)
Answer:
30
Step-by-step explanation:
Exterior angle equals sum of opposite interior angles
3x = 2x + 30
3x - 2x = 30
x = 30
