Answer:
Step-by-step explanation:
The formula for determining the the volume of a rectangular base pyramid is expressed as
Volume = 1/3 × base area × height
From the information given,
Length of base = 9 cm
Width of base = 4.6 cm
Area of base = 9 × 4.6 = 41.4 cm²
Volume of pyramid = 82.8cm³
Therefore
82.8 = 1/3 × 41.4 × height
82.8 = 13.8 × height
Dividing both sides of the equation by 13.8, it becomes
height = 82/13.8
Height = 5.94 8 cm
Answer:
23.2586 ; IQ ; hours spent studying per week
Step-by-step explanation:
Given the regression model:
y = 6.9+0.055x1 +0.107x2 + 0.0853X3.
IQ scores = (X1)
Hours spent studying each week = (X2),
one's high school average = (x3)
The multiple standard error is 6.313 and R^2=0.826.
What is the predicted GPA for a student with a IQ of 108, 32 hours spent studying per week and a high school average of 82?
X1 = 108 ; X2 = 32 ; X3 = 82
y = 6.9 + 0.055(108) + 0.107(32) + 0.0853(82)
y = 23.2586
B.
The Independent variable with the smallest effect on GPA is the variable with the smallest Coefficient, which is IQ with a Coefficient of 0.055
C.
The Independent variable whiae unit change has the greatest effect on GPA is X2, hours spent studying per week as it has the highest Coefficient of all independent variables with a Coefficient value of 0.107.
Line A is the correct answer because the line crosses the 7 dish point at the one minute point
