Answer: x=5.33333333333
Step-by-step explanation:
6=x+2/3
We simplify the equation to the form, which is simple to understand
6=x+2/3
Simplifying:
6=x + 0.666666666667
We move all terms containing x to the left and all other terms to the right.
-1x=0.666666666667-6
We simplify left and right side of the equation.
-1x=-5.33333333333
We divide both sides of the equation by -01 to get x.
x=5.33333333333
Let X represent a random variable representing the birth weights of babies, and let x be the required cut-off, then
P(X < x) = 0.02
P(z < (x - 3419)/494) = 0.02
1 - P(z < (3419 - x)/494) = 0.02
P(z < (3419 - x)/494) = 1 - 0.02 = 0.98
(3419 - x)/469 = 2.04
3419 - x = 956.76
x = 3419 - 956.76 = 2462.24
Therefore, the weight to be used as cut-off is 2462.24 g

Answer:
(C) Annie did not make a mistake
Step-by-step explanation:
To isolate the variable k in the equation
, we'd have to subtract 7.5 from both sides so we just had k on one side.
This is exactly what Annie did, and therefore, her answer is correct.
Hope this helped!
4 red marbles
6 blue marbles
8 green marbles
Add:
4 + 6 = 10
10 + 8 = 18
18 total marbles
Green marbles/total marbles
8/18
Simplify:
8 ÷ 2 = 4
18 ÷ 2 = 9
Simplest form = 4/9
8/18 = 4/9
D. 4/9
