Answer:
312cm2
Step-by-step explanation:
Area of the triangles:
A =1/2bh
A=1/2(10*12) = 1/2*120=60.
There are two triangles. 60*2=120. 120 is the area of both triangles.
Area of the rectangle:
16*12=192.
120+192=312cm2
Answer:
Option A The linear model on tar content accounts for 92.4% of the variability in nicotine content.
Step-by-step explanation:
R-square also known as coefficient of determination measures the variability in dependent variable explained by the linear relationship with independent variable.
The given scenario demonstrates that nicotine content is a dependent variable while tar content is an independent variable. So, the given R-square value 92.4% describes that 92.4% of variability in nicotine content is explained by the linear relationship with tar content. We can also write this as "The linear model on tar content accounts for 92.4% of the variability in nicotine content".
Answer:
Step-by-step explanation:
so jin paid a total of (140 + 16) = 156
this is 130% of what stefan spent
so 130% of what stefan paid equals 156
let x represent what stefan paid
turn ur percent to a decimal
1.3x = 156
x = 156/1.3
x = 120 <== what stefan originally spent
and stefan made : (156 - 120) = $ 36 <==
Answer:
