Answer:

B. Vanessa only established some of the necessary conditions for a congruence criterion.

Step-by-step explanation:

The diagram does support the claim that \overline{KL}\cong\overline{MN}  

KL

≅  

MN

start overline, K, L, end overline, \cong, start overline, M, N, end overline because they both have two tick marks.

Step 1 is correct.

Step 2

The diagram does support the claim that \overline{LM}\cong\overline{NK}  

LM

≅  

NK

start overline, L, M, end overline, \cong, start overline, N, K, end overline because they both have a single tick mark.

Step 2 is correct.

Step 3

In this step, Vanessa claims that \triangle KLM\cong \triangle MNK△KLM≅△MNKtriangle, K, L, M, \cong, triangle, M, N, K using the side-side-side criterion. But Vanessa only established two pairs of congruent corresponding sides. To use this criterion, we must establish three pairs of congruent sides.

Vanessa would be able to use this criterion if she first established that \overline{MK}\cong\overline{KM}  

MK

≅  

KM

start overline, M, K, end overline, \cong, start overline, K, M, end overline (this can be done with the reason that line segments are congruent to themselves).

The first error Vanessa made in her proof was option B.

Vanessa only established two pairs of congruent corresponding sides

polygons are congruent if they may be identical in size and shape - that is, if their corresponding angles and sides are the same.

Congruent shapes are shapes that can be exactly equal. The corresponding facets are identical and the corresponding angles are equal.

⇒KL≅  MN   9K, L, end overline)

⇒LM≅  NK

⇒MNK△KLM≅△MNK  (triangle, K, L, M)

Vanessa would be able to use this criterion if she first established that

⇒MK≅  KM

Answer:

The expected number of ticket holders that will fail to show for the flight is 13.9.

Step-by-step explanation:

For each ticket holder, there are only two possible outcomes. Either they fail to show up for the flight, or they do not. Ticket holders are independent. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

5% of passengers fail to show for flights

This means that [tex]p = 0.05[/tex]

278 tickets sold

This means that [tex]n = 278[/tex]

What is the expected number of ticket holders that will fail to show for the flight?

[tex]E(X) = np = 278*0.05 = 13.9[/tex]

The expected number of ticket holders that will fail to show for the flight is 13.9.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

In our daily life, we always see circular objects for example our bike wheel.

The longest line which can be drawn inside the circle will be the diameter.

Area of the circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.

As per the given circle,

(a)→ Center is at K

(b)→ Radius is at KI

(c)→ Chord is at KL

(d)→ Diameter is at JKI

(e)→ Sectant is at JL

(f)→ Tangent is at GI

(g) →Point of Tangency is at H

(h)→ Minor Arc is at JL

(i)→ Major Arc is at HIJ

(j)→ Semicircle is at HIL

(k)→ Center Angle is at HKI

(l) →Inscribed Angle is at HIJ

Hence "All parts of the circle have been shown above".

Answer:

-2.75

-1.75

-0.75

0.25

1.25

Step-by-step explanation:

The value of x is given in the top row of the table. We can complete the rest of the table by plugging in the corresponding values of x into the equation and solve for y.

For example:

y = (-2) - 3/4 = -2.75

y = (-1) - 3/4 = -1.75

y = (0) - 3/4 = -0.75

y = (1) - 3/4 = 0.25

y = (2) - 3/4 = 1.25

Answer:

Compound interest is better, by $14.36.

Step-by-step explanation:

Simple Interest:

The simple interest formula is given by:

[tex]E = P*I*t[/tex]

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

[tex]T = E + P[/tex]

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Total amount in compound interest:

$3,000 in a certificate of deposit that pays 2.8% interest, compounded annually for 4 years. This means, respectively, that [tex]P = 3000, r = 0.028, n = 1, t = 4[/tex]

So

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(4) = 3000(1 + \frac{0.028}{1})^{4} = 3350.38[/tex]

Total amount in simple interest:

[tex]P = 3000, I = 0.028, t = 4[/tex]

So

[tex]E = P*I*t = 3000*0.028*4 = 336[/tex]

[tex]T = E + P = 3000 + 336 = 3336[/tex]

Which is better and by how much?

Higher earning with compound interest, so it is better.

3350.36 - 3336 = 14.36

Compound interest is better, by $14.36.

Answer:

18 nuts in 12 minutes, 13.5 nuts in 4 minutes and 90 nuts in one hour

Step-by-step explanation:

12 min :

12/6 = 2    

2 x 9 = 18 nuts in 12 minuts

4 min:

6/4 = 1.5

1.5 x 9 = 13.5 nuts in 4 minutes

(round to 13 if whole nuts only)

1 hour:

1 hour = 60 mins

60/6 = 10

9 x 10 = 90 nuts in one hour

Add all numbers and you get 2160

Then 2160÷2= 1080
