A farmer plows a corn field in the shape of a rectangle that has an area of 15840 square yards if the length of the field is 132

igomit [66]

Answer:

Width= 120

Step-by-step explanation:

We know that L*W= A

So lets put in the variables we know into the equation.

L= 132 yards

A= 15840

132 * W= 15840

All we need to do is divide 15840 by 132

15840/132= 120

W=120

The st. joe company grows pine trees and the average annual increase in tree diameter is 3.1 inches with a standard deviation of

77julia77 [94]

Solution: We are given:

μ=3.1,σ=0.5,n=50

We have to find P(Mean <2.9)

We need to first find the z score

z= (xbar-μ)/(σ/sqrt(n))

=(2.9-3.1)/(0.5/sqrt(50))

=(-0.2)/0.0707

=-2.83

Now we have to find P(z<-2.83)

Using the standard normal table, we have:

P(z<-2.83)=0.0023

Therefore the probability of the sample mean being less the 2.9 inches is 0.0023

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

harina [27]

The equation of line is:

$y=-\frac{1}{2}x+6$

Further explanation:

Given

y = 2x + 2

Comparing it with standard form:

y=mx+b

Let m1 be the slope of given line

$m_1=2$

We know that product of slopes of two perpendicular lines is -1

Let m2 be the slope of second line

$m_1.m_2=-1\\2*m_2= -1\\m_2 = -\frac{1}{2}$

Putting the value of m2 in standard form

$y=-\frac{1}{2}x+b$

To find the value of b, putting (6,3) in equation

$3=-\frac{1}{2}(6)+b\\3=-3+b\\3+3=b\\b=6$

Putting the values of b and m, we get

$y=-\frac{1}{2}x+6$

The equation of line is:

$y=-\frac{1}{2}x+6$
