They have no relation, except for the fact that they intersect. If the equations were instead y = +5/4x - 1/2 and y = -4/5x + 2, or y = +4/5 + 2 and y = -5/4x -1/2, then they would be perpendicular.
Option 3 is the right answer.
Step-by-step explanation:
For the given lines y = -4/5x+2 and y = -5/4x - 1/2
we have to identify whether lines are parallel or perpendicular.
As we know if two lines are perpendicular then gradients of two lines will in the form of
m1 m2=(-1)
and if the lines are parallel then the gradients of the lines will be same.
m1=m2
Here m1 = -4/5 and m2 = -5/4
Therefore
m1m2=(-4/5)(-5/4)=(+1)
and
m1≠m2
So both the lines are neither parallel nor perpendicular to each other.
Option 3 is the right answer.

Find the value of n.
Answers
Answer:
n = 2
Step-by-step explanation:
sin 30° = ½
tan 45° = 1
then
sin 30° : tan 45° = 1 : n
½ : 1 = 1 : n
n = 2
The value of n for the trigonometric expression will be n = 2
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that the ratio sin 30°: tan 45º can be written in form 1: n. The value of n will be calculated as:-
sin 30° = ½
tan 45° = 1
Then,
sin 30° : tan 45° = 1 : n
½ : 1 = 1 : n
n = 2

In 2005 the U.S. Census Bureau reported that 68.9% of American families owned their homes. Census data reveal that the ownership rate in one small city is much lower. The city council is debating a plan to offer tax breaks to first-time home buyers in order to encourage people to become homeowners. They decide to adopt the plan on a 2-year trial basis and use the data they collect to make a decision about continuing the tax breaks. Since this plan costs the city tax revenues, they will continue to use it only if there is strong evidence that the rate of home ownership is increasing. a) In words, what will their hypotheses be
Answers
Answer:
H0 : Number of homeowners stays the same
H1: Number of homeowners increases.
Step-by-step explanation:
The hypothesis is to test if the level of home ownership rises or doesn't.
For this type of experiment,
The null hypothesis is the current level of home ownership.
The alternative hypothesis which is usually the opposite of the null is meant to challenge the claim of the Null. Hence, the null hypothesis will support the claim or hypothesis of the study, which is that the number of homeowners increases, hence, does not remain the same.
Therefore,
H0 : Number of homeowners stays the same
H1: Number of homeowners increases.

The ratio is 2:5 red beads to blue beads. If you have a TOTAL of 21 beads, how many are red, and how many are blue beads?
Answers
Answer:
Number of red beads = 6
Number of blue beads = 15
Step-by-step explanation:
Number of total beads = 21
Ratio of red beads to the blue beads = 2 : 5
Therefore, number of red beads I have = [tex]\frac{2}{2+5}(\text{Total number of beads})[/tex]
= [tex]\frac{2}{7}\times 21[/tex]
= 6 beads
Number of blue beads = [tex]\frac{5}{2+5}\times (21)[/tex]
= [tex]\frac{5}{7}\times 21[/tex]
= 15 beads
Therefore, number of red beads = 6
And number of blue beads = 15

5 points A farmhouse shelters 10 animals. Some are goats and some are ducks. Altogether there are 36 legs. How many ducks and goats are there?
Answers
Answer:
2 ducks and 8 goats
Step-by-step explanation:
let goat be g
let duck be d
d + g = 10
ducks have 2 legs, 2d
goats have 4 legs, 4g
2d + 4g = 36
making d the subject in the first equation;
d = 10 - g
put in second equation
2(10 - g) + 4g = 36
20 -2g + 4g = 36
2g = 36 - 20
2g = 16
g = 8
if g is 8
d = 10 - 8
d = 2
