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. Use the g
valentina_108 [34]

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.

Point C is located at (1, 2) and point D is located at (−4, −2). Find the x value for the point that is 1 over 4 the distance fr
stellarik [79]

Answer:

-0.25

Step-by-step explanation:

Coordinates of C  = (x_{1} ,y_{1} )=(1,2)

Coordinates of D =  (x_{2} ,y_{2} )=(-4,-2)

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.

x=\frac{mx_{2}+nx_{1}}{m+n}

y=\frac{my_{2}+ny_{1}}{m+n}

Substituting the values:

x=\frac{1*-4+3*1}{1+3}

x=\frac{-1}{4}

x=-0.25

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
