<h3>Answer:  A) EF > DF</h3>

==========================================================

Explanation:

Recall that for any triangle, the three angles always add to 180

D+E+F = 180

60+40+F = 180

100+F = 180

F = 180-100

F = 80

Angle F being 80 degrees makes it the largest angle of the triangle.

The side opposite angle F is the longest side. ED is the longest side

The shortest side is DF because it is opposite the smallest angle

Therefore, this must mean EF > DF

Human visual inspection of solder joints on printed circuit boards can be very subjective. Part of the problem stems from the nu
Basile [38]

Answer:

a) 0.8841

b) 0.0435

Step-by-step explanation:

A : the set of joints deemed defective by inspector A.

B: the set of joints deemed defective by inspector B.

U: the set of all joints.

The problem says |A|=724, |B|=751, |A∪B|=1159, |U|=10000. Hence, with the help of Venn diagram we can answer the following:

Part a)

This asks for the number of joints that are ∉(A∪B).

hence,

P (∉(A∪B)) :

\frac{10000-1159}{10000} \\\\=0.8841

part b)

This asks for the number of joints that are in B but not in A, which Is represented as the set B−A

= \frac{|B| - |AandB| }{|U|}\\\\=  \frac{751-316 }{10000}\\\\= 0.0435

Suppose 34% of a large sample of a population favor a tax increase. If there are 95,000 people in the population, about how many
krek1111 [17]
To find 34% of 95,000 you would multiply .34(95,000)
This would be 32,300 people

Use the quadratic formula to find the solutions to the quadratic equation
xz_007 [3.2K]

Answer:

<em>Solution ~  x = -4/5, and x = 1</em>

Step-by-step explanation:

1. Let us apply simple algebra to first factor this quadratic equation:

<em>5x² - x - 4 = 0,</em>

<em>( 5x^2 + 4x ) + ( -5x - 4 ) = 0,</em>

<em>x ( 5x + 4 ) - ( 5x + 4 ) = 0,</em>

<em>( 5x + 4 )( x - 1 ) = 0</em>

2. Now that this is factored, we can apply the zero factor principle to derive the two solutions to this equation:

<em>5x + 4 = 0, and x - 1 = 0,</em>

<em>5x = - 4, and x = 1,</em>

<em>Solution: x = -4/5, and x = 1</em>
