Well from what i know here's what i would put........
-4 * -2 = 8 - 2 = 6
-4 * -1 = 4 - 2 = 2
-4 * 0 = 0 - 2 = -2
so it does represent a function......I really hope that helped!!
A) 1% lidocaine -x g, 0.01x pure lidocaine
5% lidocaine -y g, 0.05y pure lidocaine
(1)0.01x+0.05y=350*0.02
0.01x g we get from1% lidocoine and 0.05y g we get from 5% lidocoine
(2) x+y=350
x g is mass 1% lidocoine, we combine it with y g 5%,
so we get x+y, and we need 350g,
so x+y should be equal 350, x+y=350
we get system of 2 equations that we need to solve to find x and y
(1)0.01x+0.05y=350*0.02
(2) x+y=350
we can solve it by substitution, find x from (2) equation
x=350-y, substitute it into (1)
instead of x we put (350-y)
0.01(350-y)+0.05y=7
3.5-0.01y+0.05y=7
0.04y =3.5
y=87.5g 5% lidocaine
b)x=350-87.5=262.5 g 1% lidocaine
c) 350g =350000 mg
Answer:
The answer is B
Step-by-step explanation:
Definition of margin of error is simply expected error from result of a survey. Which means the actual vote results are in the range of plus or minus %3.
On this survey the result is %55 percent in favor of Taylor and the margin of error is %3. That means in the real election Taylor will get votes in between %52-%58. In other word
The sample proportion minus the margin of error is greater than 0.50, which provides evidence that more than half of all likely voters plan to vote for candidate Taylor.
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation;
3*n-4-(14)=0
Pull out like factors :
3n - 18 = 3 • (n - 6)
Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : n-6 = 0
Add 6 to both sides of the equation :
n = 6
Answer:
coordinates of the Midpoint = (7 ,4).
Step-by-step explanation:
Given : endpoints are H(10, 1) and K(4, 7).
To find :Find the coordinates of the midpoint .
Solution : We have given that endpoints are H(10, 1) and K(4, 7).
By the mid point segment formula :
.
Here,
Md point =.
Mid point = .
( 7 ,4)
coordinates of the Midpoint = (7 ,4).
Therefore, coordinates of the Midpoint = (7 ,4).
