Jorge scored 18 out of 45 free throws. What decimal
is equivalent to the fraction of free throws Jorge made?

Answers

Answer:

0.4 (not rounded)

Step-by-step explanation

You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 18 and 45 using

GCF(18,45) = 9

18÷945÷9=25

We know that

25

is the same as

2÷5

Then using

Long Division for 2 divided by 5

gives us

=0.4


If BFD and AFC are right angles and
m CFD = 72°, what is the value of x?
18
36
108
72

Answers

Answer:

72

Step-by-step explanation:

If BFD is a right angle and it gives you CFD that means that you do 90 - 72 to find CFB cause it 90 all togther

CFB = 18 deg

now it also tells us CFA is a 90 deg angle so we do the same thing

90 - 18 = 72

What point is on both lines y=12x+3 and y=x+1

(no graph)

Answers

Step-by-step explanation:

by having two equations that have the same point, you can set the two equations equal to each other

y = 12x + 3, y = x + 1

12x + 3 = x + 1

11x = -2

x = -2/11

when you find the the x value, plug it back into either one of the equations

y = x + 1

y = (-2/11) + 1

y = 11/11 - 2/11

y = 9/11

the point (solution):

(-2/11, 9/11)

Answer:

(-2|11, 9|11)

what is the expression for the probability when the disease D is present but the test says its not? P = Event that test is positive, D = Event disease is present

Answers

Answer:

[tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Step-by-step explanation:

Given

P = Test is positive

D = Disease is present

Required

Write an expression when disease is present but test says that the disease is not present

The above statement can be split to two

Disease is Present          &        Test is not positive

The first statement:

Disease is Present  means D

The second statement

Test is not positive means not P

Mathematically;

not P means P' or [tex]P^c[/tex]

So, the required expression is: [tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Answers

C. Good luck with your test

Answer:

C. x - 5y - 30 = 0

Step-by-step explanation:

Y = x/5 - 30

y + 30 = x/5

you multiply both sides by 5

5y + 30 = x

you subtract x from both sides

- x + 5y + 30 = 0

which is the same as

x - 5y - 30 = 0

What angle relationship describes ∠VQR and ∠QRW?

segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively

A) Alternate interior angles
B) Alternate exterior angles
C) Corresponding angles
D) Vertical angles

Answers

Answer:

its A on the quiz (alternate interior)

Step-by-step explanation:

The required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.

Given that,
Segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively. What angle relationship describes ∠VQR and ∠QRW is to be determined.

What are parallel lines?

Parallel lines are defined as the pair of line that has the distance between the point corresponding to the line are equal and this line met at infinity.

What is angle?

The angle can be defined as the one line inclined over other line.

Since it is to describe that what is the relationship between  ∠VQR and ∠QRW.
Here, both angles are interior and alternate in the figure so both angles have a relationship to the alternate interior angle by property of parallel lines.


Thus, the required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.
