what is the equation of the line that passes through (6,4) and (4,1)

Answers

Answer:

y = 3/2*x - 5

Step-by-step explanation:

Lets say that P1=(6,4) and P2=(4,1) and that the form of the equation must be y=m*x+b where m is the slope and b the independent variable. Then having two given points we can use the slope formula to find the slope value as:

P1=(x1,y1) and P2=(x2,y2)

slope formula --->   m=(y2-y1)/(x2-x1)

Replacing the given points --->    m=(1-4)/(4-6) = 3/2

then replacing the slope value obtained:

y = 3/2*x + b

Now lets find the value of b. For this we have to replace in the equation a point it can be P1 or P2, i will replace P2:

1 = 3/2*4 + b

1 = 6 + b

1 - 6 = b

-5 = b

therefore the line equation is:

y = 3/2*x - 5

C) - a∥b by the converse of the corresponding angles theorem.

D) - c∥d by the converse of the alternate interior angles theorem.

Answers

I think the answer is C

c∥d by the converse of the same-side interior angles theorem.

What is same-side interior angles theorem.?

If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

Given:

m∠3+m∠8=180°

As, we can see that <3 and <8 are lies on same side of transversal.

So, the line that are parallel are c and d converse of the same-side interior angles theorem.

Hence, c∥ d by the converse of the same-side interior angles theorem.

Pina filled out the following information on the back of her monthly statement:
Ending balance from statement $1,139.78
Deposits outstanding
+ $280.67
Total of checks outstanding
- $656.91
Revised statement balance
Balance from checkbook
$763.54
Find Pina's revised statement balance. Does her account reconcile?

Answers

Answer:

yes

Step-by-step explanation:

It is true that Pina's account reconciles.

The monthly statement is given as:

Ending balance from statement $1,139.78 Deposits outstanding  + $280.67 Total of checks outstanding  - $656.91 Revised statement balance  $ Balance from checkbook  $763.54

Start by calculating the revised statement at the end of the month.

This is calculated using:

[tex]Revised = Ending\ Balance + Deposit\ Outstanding - Checks\ Outstanding[/tex]

So, we have:

[tex]Revised = \$1139.78 + \$280.67 - \$656.91[/tex]

Evaluate the expression

[tex]Revised = \$763.54[/tex]

By comparison, the revised statement equals the balance from the checkbook.

Hence, we can conclude that her account reconciles.

Quadrilateral EFGH is a scaled copy of quadrilateral ABCD. Select all of the true statements. *

Segment EF is twice as long as segment AB.
Segment CD is twice as long as segment FG.
The measure of angle HEF is twice the measure of angle DAB.
The length of segment EH is 16 units.
The area of EFGH is twice the area of ABCD.

Answers

Answer:

✔️Segment EF is twice as long as segment AB

✔️The length of segment EH is 16 units.

Step-by-step explanation:

Since quadrilateral ABCD is scaled to form quadrilateral EFGH, both are similar polygon.

Therefore: scale factor = ratio of any of their corresponding side

Scale factor = GH/CD = 12/6 = 2

This means quadrilateral EFGH is twice the size of quadrilateral ABCD.

The shape of the original polygon remains the same while the size increases.

This implies that, all segments of quadrilateral ABCD increases proportionally times 2 to give us corresponding lengths of the segments of quadrilateral EFGH.

Since shape remains the same, their corresponding angles are congruent and the same in measure.

Therefore, the following statements are true and correct:

✔️Segment EF is twice as long as segment AB

(EF = AB*scale factor = 3*2 = 6)

✔️The length of segment EH is 16 units.

(EH = AD*scale factor = 8*2 = 16)

Assume that a procedure yields a binomial distribution with a trial repeated
n=5 times. Use some form of technology to find the probability distribution given the probability p=0.156 of success on a single trial.

Answers

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

n = 5, p = 0.156, and q = 0.844.

r = 0, P = ₅C₀ (0.156)⁰ (0.844)⁵⁻⁰ = 0.428

r = 1, P = ₅C₁ (0.156)¹ (0.844)⁵⁻¹ = 0.396

r = 2, P = ₅C₂ (0.156)² (0.844)⁵⁻² = 0.146

r = 3, P = ₅C₃ (0.156)³ (0.844)⁵⁻³ = 0.027

r = 4, P = ₅C₄ (0.156)⁴ (0.844)⁵⁻⁴ = 0.002

r = 5, P = ₅C₅ (0.156)⁵ (0.844)⁵⁻⁵ ≈ 0
