Answer:

X=-5.5

Step-by-step explanation:

3/4x+5=5/6(move constant to the right)

3/4x=6/5-6(calculate)

3/4x=-25/6(multiple both sides)

X=-50/9 (solution )

X= -5.5( solution that you need)

The value of x in all case is

1. The value of x is 2

2. The value of x is 1

3.The value of x is 57

4.The value of x is 93

<h3>What is complementary and supplementary angle?</h3>

If the sum of two angles is 180 degrees then they are said to be b angles, which form a linear angle together. Whereas if the sum of two angles is 90 degrees, then they are said to be complementary angles, and they form a right angle together.

1. As the given angle is 90 degree i.e., complementary angle.

So,

54+10x+16=90

20=10x

x=2

2. 65x-12=43x+10 (Vertically opposite angle)

22x= 22

x=1

3. 72= x+15 (Vertically opposite angle)

x= 57

4.x+244+23=360 (Complete angle)

x=93

Find the principal that will yield a simple interest of Rs 9000 in 5 years at a rate of 6% per annum.

damaskus [11]

9514 1404 393

Answer:

₹ 30000

Step-by-step explanation:

The simple interest formula is ...

I = Prt . . . . . . principal P invested at rate r for t years

Fill in the values you know, and solve for the one you don't know.

9000 = P(0.06)(5)

9000/0.30 = P = 30000

The principal that will give ₹9000 in interest is ₹30000.

Which of the following ordered pairs could be placed in the table and still have the relation qualify as a linear function?

hammer [34]

The answer is B, by the way don't listen to the guy above me, because 1,7 is completely wrong. the answer is (2, 13), because the table is showing that for every value of x the output, (y), changes by 3, and according to the table,we need to add three more which equals thirteen, then we move the x value up.

I hope this helps!

Determine whether the two events are disjoint for a single trial. (Hint: Consider "disjoint" to be equivalent to "separate" o

densk [106]

Answer: Hello there!

we have two events and we want to see if they are disjoint, where disjoint means that they are "not overlapping" or that "cant occur at the same time"):

Randomly selecting a car from the vehicle assembly line and getting one that is free of defects.

Randomly selecting a car from the vehicle assembly line and getting one with a dead battery.

Clearly, if the car you got has a dead battery, it has a defect, then bot events cant occur at the same time.

now let's analyze the options:

A. The events are disjoint. The first event is the complement of the second.

There are other defects that can occur to the car, then the options aren't complementary, because they don't cover all the options.

B. The events are disjoint. They cannot occur at the same time.

As I said before, this is true!

C. The events are not disjoint. They can occur at the same time

This is false, as i said before the dead batery implies a defect in the car, then both events can not happend at the same time.

D. The events are not disjoint. The first event is not the complement of the second.

It is true that the first event is not the complement of the second, but the events are disjoint, so this is false.

then the correct option is option C.

According to the Harris Poll, 70 % of dog owners buy their dogs holiday presents. Suppose you select a random sample of 25 dog o

Lana71 [14]

The concluding part is missing in the question and it says we should find the probability that 2 of the people selected cook meals for their dogs

Answer:

P(x2) = 0.1857

Step-by-step explanation:

N = 30; since there are 30 people that own dogs

k = 21; since there are 70% of dog owners who buy gifts for their dogs

n = 25; since we randomly select 25 people among the dog owners

x = 2; since we randomly select 2 people who cook meals for their dogs

Therefore, for clarity sake the solution is in the attachment ;

And the probability is 0.1857
