im not trying to get free pionts but what grade is that
Answer:
- 12=0.005×w
- the number is 2400
Step-by-step explanation:
An appropriate representation of the problem can be had by using a variable to represent "what number" and then using the math equivalent symbols for the English words. If "what number" is represented by w, then we want to translate ...
0.5% of w is 12 . . . . English
0.005 × w = 12 . . . . . . . matches choice 1
__
This can be solved by multiplying by 200
200(0.005w) = 200(12)
w = 2400
The number is 2400.
Answer: Our required probability is
Step-by-step explanation:
Since we have given that
Number of red envelopes = 3
Number of blue envelopes = 3
Number of green envelopes = 1
We need to select 3 envelopes in such a way that at least one envelope is a red.
So, it becomes,
Hence, our required probability is
Answer:
B and D
Step-by-step explanation:
Equation is 2x + y = -4
Step-by-step explanation:
- Step 1: Use the point slope form to get the equation. The point is (x1, y1) = (-4, 4) and slope, m = -2
Point slope Form ⇒ y - y1 = m(x - x1)
⇒ y - 4 = -2(x - -4)
⇒ y - 4 = -2(x + 4)
⇒ y - 4 = -2x - 8
⇒ 2x + y = -4 is the equation
