Answer:
B) Only (-3, 5)
Step-by-step explanation:
Slot in the options into the equation
(-2, 4),
Compare with (x, y)
x = -2, y =4
y =-3x - 4
4 =( -3 * -2 ) - 4
4 = 6 - 4
This is not true hence, option A is wrong
Using (-3, 5)
x = -3, y= 5
5 = (-3*-3) - 4
5 = 9 - 4
This is correct hence, option B is correct
Option c is wrong because (-2,4) is not a solution to the equation
Option D is wrong because option B is correct
Answer:
There is extra information.
Step-by-step explanation:
Answer:
38% probability that a randomly selected student is female or a physics major.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
Physics majors or female
10 physics majors(of which 3 are female).
12 female(the 3 female physics majors have already been counted, so we count 9)
Total outcomes:
50 students, so 
Probability
38% probability that a randomly selected student is female or a physics major.
Answer:
16/7 =x
Step-by-step explanation:
We can use ratios to solve
3 x
----- = ---------
21 16
Using cross products
3*16 = x *21
48 = 21x
Divide by 21
48/21 = x
16/7 =x
Answer:
it is option D standard form
