3.4+0.4+4.17=7.97 you just have to try different combinations of different numbers with the decimals.
The slope of the line is -3/4
Answer:
A. 0.4880
Step-by-step explanation:
First, find the z-score:
z = (x − μ) / σ
z = (13.5 − 13.56) / 2.24
z = -0.03
Using a z-score table:
P(z < -0.03) = 0.4880
You set up the equation. Then you do 20 minus 12 which gives you 8. You’re left over with x/3 equals 8. 8 multiplied by 3 gives 24, so x equals 24
