Step-by-step explanation:

Coordinates of midpoint

[tex] = \bigg( \frac{ - 2 + 7}{2}, \: \: \frac{6 - 1}{2} \bigg) \\ \\ = \bigg( \frac{5}{2}, \: \: \frac{5}{2} \bigg) \\ \\ = ( 2.5, \: \: 2.5 )[/tex]

Answer:

[tex](4 i+ 3)(5 - 2i)[/tex]

[tex]= - {8i}^{2} + 20i + 15 - 6i[/tex]

[tex]= - {8i}^{2} + 14i + 15 [/tex]

Answer:

Step-by-step explanation:

x-intercept:  Set y = 0 and solve for x:

 0 = mx + b, or mx = -b, or x = -b/m.  x-intercept is then (-b/m, 0)

y-intercept:  Set x = 0 and solve for y:  y = m(0) + b, or y = b.  y-intercept is then

 (0, b).

Answer:

[tex]Dom_{f}=[-3,\infty)[/tex]

[tex]Range_{f}=(-\infty,-2][/tex]

Step-by-step explanation:

I understand the correct function is [tex]f(x)=-\sqrt{x+3} - 2[/tex]

Domain of f

[tex]x+3\geq 0\\x\geq -3[/tex]

Thus, [tex]Dom_{f}=[-3,\infty)[/tex]

Range of f

Answer:

[tex] 65 \leqslant x \leqslant 100 \\ = 65\%[/tex]

Answer:

The Greatest Common Factor (GCF) for 65 and 100, notation CGF(65,100), is 5.

Step-by-step explanation:

Explanation:

The factors of 65 are 1,5,13,65;

The factors of 100 are 1,2,4,5,10,20,25,50,100.

So, as we can see, the Greatest Common Factor or Divisor is 5, because it is the greatest number that divides evenly into all of them.

Answer:

15

Step-by-step explanation:

5n = 82 - 7

Answer:

[tex]\frac{29}{50}[/tex]

Step-by-step explanation:

[tex]\frac{29}{50}[/tex] put into decimal form is 0.58 (aka 58%)

The person above me was correct but didn't have the answer in fraction form.

The probability that a randomly chosen person on the bus is an adult chaperone or a male student is 0.58.

We have the following data -

On a field trip there are 6 adult chaperones, 21 female students, and 23 male students on a bus.

We have to find the probability that a randomly chosen person on the bus is an adult chaperone or a male student.

The formula to calculate the probability of an event is -

P(A) = n (A) / n(S)

Where -

n(A) - Number of favorable outcomes.

n(S) - Number of elements in the sample space.

In the question given to us, we have -

n (A) = favorable outcomes = 23 + 6 = 29

n (S) =  Elements in the sample space 23 + 21 + 6 = 50

Hence, the probability that a randomly chosen person on the bus is an adult chaperone or a male student is -

P(A) = [tex]\frac{n(A)}{n(S)}[/tex] = [tex]\frac{29}{50}[/tex] = 0.58

Hence, the probability of choosing will be 0.58.

Answer:

For the first part, it would be: 15/4 - 9/4 = 6/4

The second part would be 1 1/2

Step-by-step explanation:

You would do 3*4 + 3 to get 15/4, you would do 2*4 + 1 to get 9/4, then you would subtract 9 from 15 to get 6. 6/4 is 1 1/2

The volume of the garage is 64 times the volume of the model

Answer:

60 feet from the center.

Step-by-step explanation:

As this it was designed as whispering gallery, and we know the whole length of the hall, and the highness of the ceiling we can use the following expression:

c² = a² - b²   (1)

Where:

c: Length from center to foci.

a: length of half the hall.

b: length of the ceiling.

Replacing the given data into (1) we have:

c² = (130/2)² - (25)²

c = √65² - 500

c = √3600

Hope this helps

Answer:

3.5 if the 901589 a whole number but 5 if it is supposed to be seperated

Step-by-step explanation:

Answer:

3.5 if the 901589 a whole number but 5 if it is supposed to be seperated

Step-by-step explanation:

Answer:

1. ΔUJN ≅ ΔUGN by SAS rule of congruency

2. Side Angle Side Rule of congruency

3. JN ≅ GN, ∠JUN ≅ ∠NUG, ∠UNJ ≅ ∠UNG, NU ≅ NU

4. UN bisects angle ∠JUG and UN bisects segment JG

Step-by-step explanation:

The given figure consists of three triangles

1. ΔUJN, 2. ΔUGN, and 3. ΔUJG

Whereby segment UN is perpendicular to segment JG, we have;

ΔUJN and ΔUGN are right triangles

∴ ∠UNJ = ∠UNG = 90° by definition of segment UN being perpendicular to segment JG

NU ≅ NU by reflexive property

Whereby UN bisects ∠JUG and segment JG, we have;

JN = GN by definition of a bisected segment

Therefore, we have;

1. ΔUJN ≅ ΔUGN by SAS rule of congruency

2. Side Angle Side Rule of congruency

3. JN ≅ GN, ∠JUN ≅ ∠NUG, ∠UNJ ≅ ∠UNG, NU ≅ NU

4. UN bisects angle ∠JUG and UN bisects segment JG

Answer:

y=8x-4

Step-by-step explanation:

Answer:

Impossible without X

Step-by-step explanation:

Proof:

-1/4y = 1 -2x

y = -4 + 8x

2x - ([tex]\frac{-4+8x}{4}[/tex])=1

2x-(-1+2x)=1

2x+1-2x=1

1 = 1

Recursive

2x = 1+1/4y

x = 1/2 + 1/8y

2(1/2 + 1/8y) -1/4y = 1

1 + 1/4y - 1/4y =1

1  = 1

Answer:

8 red marbles.

Step-by-step explanation:

All together we have 40 marbles. The fraction of marbles that are red is 1/5 which means that we should divide the total number of marbles, which is 40 by the denominator ( Bottom number of fraction ) 5 so that we get the number of groups that have 1 red marble in them. In this case we have 8 groups.

40/5=8

You always divide by the denominator ( Bottom number of fraction ) first and then you multiply your answer by the numerator ( Top number of fraction ) .

If each group has 1 red marble in it and we have 8 groups, it means that we have 8 red marbles in the bag.

1 * 8 = 8 red marbles in the bag

If the numerator (number above the fraction line) was more than one, then this would mean that we have more than 1 marble in each group of marbles.

Example:

If we had 3/5 we would have 3 marbles in each group of marbles. This means that instead of doing 1 * 8 we would have to do 3 * 8 = 24. We would have 24 red marbles in the bag.

Easy and quick way if you do not need the explanation:

Another way we could do this is by simply multiplying the fraction ( 1/5 ) by the total number of marbles ( 40 ). This would still give us an answer of 8 red marbles in the bag. 40/5=8, 8*1=8
