7a + 6c + 9a - 15c
-- Look for all the 'a's 7a, 9a
-- Addum up 16a
-- Look for all the 'c's 6c, -15c
-- Addum up -9c
-- Write the results 16a - 9c
Answer:
Yes, the value 1411.8 cm³ is significantly high.
Step-by-step explanation:
Consider the provided information.
The brain volumes (cm cubed) of 20 brains have a mean of 1111.2 cm cubed and a standard deviation of 125.3 cm cubed.
The range rule of thumb to identify the limits separating values that are significantly low or significantly high is:
The range rule of thumb identifying significant values are as.
Significantly low values are μ-2σ
Substitute the μ = 1111.2 and σ = 125.3 in above formula.
1111.2-2(125.3)=860.6
Significantly high values are μ+2σ
Substitute the μ = 1111.2 and σ = 125.3 in above formula.
1111.2+2(125.3)=1361.8
The value is significantly high due to the value 1411.8 cm³ is not lie between the values 860.6 cm³ and 1361.8 cm³.
Hence, Yes, the value 1411.8 cm³ is significantly high.
Answer:

dodecagon = 12
Step-by-step explanation:
Answer:
-0.25
Step-by-step explanation:
Coordinates of C = 
Coordinates of D = 
Let Coordinates of A= (x,y)
Since A point is located 1/4 the distance from C to D
So the remaining distance from point A to D is 3/4
Thus the ratio of CA : AD = m:n=1:3
Now to find points of A we will use section formula i.e.
Substituting the values:
Thus Find the x value for the point that is 1 over 4 the distance from point C to point D is -0.25
Hence option a is correct
Answer: -36 + 24
Step-by-step explanation:
-4(9 + 6)=-4 x 9 = -36 than 4 x 6 = 24
