Answer:
The correct option is: (D) The psychology test score is relatively better because its z score is greater than the z score for the economics test score.
Step-by-step explanation:
Consider the provided information.
For psychology test:
Scores on the psychology test have a mean of 86 and a standard deviation of 15.
Use the Z score test as shown:
Substitute x=73, μ=86 and σ=15 in the above formula.
For economics test:
Scores on the economics test have a mean of 48 and a standard deviation of 7.
Use the Z score test as shown:
Substitute x=41, μ=48 and σ=7 in the above formula.
The Z score of psychology test is greater than the Z score of economic test.
Thus, the correct option is: (D) The psychology test score is relatively better because its z score is greater than the z score for the economics test score.
Answer:
La longitud de los lados congruentes =
B = 8.5cm
C = 8.5 cm
Step-by-step explanation:
El perímetro del triángulo isósceles mide 24 cm.
El lado no congruente mide 7 cm de largo.
Lados congruentes significa lados que son iguales o iguales entre sí.
El perímetro de un triángulo es =
Lado A + Lado B + Lado C
Por lo tanto,
24 = 7 cm + B + C
24 - 7 = B + C
17 cm = B + C
Los dos lados son congruentes,
B = C
Por lo tanto, 17 cm / 2
= 8.5 cm
La longitud de los lados congruentes =
B = 8.5 cm
C = 8.5 cm
Answer:
