Answer:

What is the sample variance of bottle weight 2.33

Step-by-step explanation:

First find the mean. The mean of the bottle weight is obtained by taking the ratio of the sum of ages and total number of ages.

Mean = (4+2+5+4+5+2+6) / 7

          = 28 / 7

          = 4

Sample Variance = \frac{\left[\begin{array}{ccc}(4-4)^{2} +(2-4)^{2} +\\(5-4)^{2} + (4-4)^{2} +\\(5-4)^{2} + (2-4)^{2} +\\(6-4)^{2}\end{array}\right]}{7-1}

                             =\frac{0+4+1+0+1+4+4}{6}

                             = 2.33

A line is perpendicular to y = 4x – 2
snow_tiger [21]

Answer:

y=-\frac{1}{4}x-10

Step-by-step explanation:

If a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m.

in this case, y=4x-2

∴ m=4 by comparing with y=mx+c

the slope of the perpendicular line is

m=-\frac{1}{4}

use the point-slope form: y-y_{0}=m(x-x_{0} )

the equation of the perpendicular line is

y+11=-\frac{1}{4}(x-4)=-\frac{1}{4}x+1\\y=-\frac{1}{4}x+1-11=-\frac{1}{4}x-10

F(x)=3x+4. Determine the value of F (X) when X equals -1
hammer [34]

ANSWER

The value of this function at x=-1 is 1

EXPLANATION

The given function is

f(x) = 3x + 4

We want to find the value of this function at x=-1.

We substitute x=-1 into the function to obtain:

f( - 1) = 3( - 1)+ 4

We multiply out to obtain:

f( - 1) =  - 3+ 4

f( - 1) = 1

Therefore the value of this function at x=-1 is 1.
