Answer:
Lane Viking's Score is 17
Black Eagles's Score is 21
Step-by-step explanation:
Let Lane Viking's Score be x and Black Eagles's Score be y.
Black Eagles's Score = 4+ Lane Viking's Score
so y = 4 + x (Equation 1)
Total Score = 38
Black Eagles's Score + Lane Viking's Score = 38
so y + x =38 (Equation 2)
Putting y's value from Equation 1 in Equation 2
4 + x + x = 38
2x = 38-4
x=34/2
x=17
Putting value of x in Equation 1
y = 4 + 17
y = 21

B
Step-by-step explanation:
Answer:
33.2%
Step-by-step explanation:
Calculate the z-scores.
z = (x − μ) / σ
z₁ = (82 − 100) / 15
z₁ = -1.2
z₂ = (98 − 100) / 15
z₂ = -0.133
Use a chart or calculate to find the probability.
P(-1.2 < Z < -0.133) = P(Z < -0.133) − P(Z < -1.2)
P(-1.2 < Z < -0.133) = 0.4470 − 0.1151
P(-1.2 < Z < -0.133) = 0.3319
Rounded to the nearest tenth, the percentage is 33.2%.
