Answer:
0.05
Step-by-step explanation:
We can correctly state that the total sample space= 100 students
40% of 100 students exercise regularly
The probability that 5 students
Picked at random exercise regularly is
Pr(5) = 5/100= 1/20
Pr(5)= 0.05
Answer:
sqrt of 3m (sorry I can't figure out how to get the symbol)
Step-by-step explanation:
M+2n^2=7m
2n^2=7m-m
2n^2=6m
n^2=3m
n= sqrt(3m)
X=1, x=-7 would be the correct answer.
Answer:
145 x 2 + 7 = 297

Answer! :
y = -2x + 5
Step by Step! :
slope intercept form:
y = mx + b
m being slope, b being the y intercept.
To find the slope, use this equation:
y^2 - y^1 / x^2 - x^1
Plug in your points.
(-1) - (7) / (3) - (-1)
-8 / 4
-2 is your slope! (y = -2x + b)
To solve for b, plug in any one of your points and solve for b. Let's use (3, -1)
-1 = -2(3) + b
-1 = -6 + b
5 = b
Your new equation is...
y = -2x + 5
