Answer:  The correct options are

(A) DEF.

(C) FED.

Step-by-step explanation:  We are given to select the correct options that describes an angle with a vertex at E.

We know that

while writing the name of an angle, we always write the vertex in the middle and the points on the two legs of the angle are written on the two sides, left and right.

<u><em>Option (A):</em></u>  DEF.

Since the vertex E is written in the middle and the points D and F on the two legs ED and EF are written on the left and right side respectively,

so DEF describes an angle with vertex E.

<u><em>Option (B):</em></u>  DFE.

Since the vertex E is not written in the middle, so DFE does not describes an angle with vertex E.

<u><em>Option (C):</em></u>  FED.

Since the vertex E is written in the middle and the points F and D on the two legs EF and ED are written on the left and right side respectively,

so FED describes an angle with vertex E.

<u><em>Option (D):</em></u>  EFD.

Since the vertex E is not written in the middle, so EFD does not describes an angle with vertex E.

Thus, the correct descriptions of an angle with vertex E are DEF and FED. The angle is shown in the attached figure below.

Options (A) and (C) are CORRECT.

x/2 + 10 = 24

2(x/2 + 10) = 2(24)

x + 20 = 48

x = 48 - 20

x = 28

A certain restaurant always overbooks. If possible. At 7:00 pm the restaurant can seat 50 parties, but takes reservations for 53
oee [108]

Answer:

The probability that the restaurant can accommodate all the customers who do show up is 0.3564.

Step-by-step explanation:

The information provided are:

  • At 7:00 pm the restaurant can seat 50 parties, but takes reservations for 53.
  • If the probability of a party not showing up is 0.04.
  • Assuming independence.

Let <em>X</em> denote the number of parties that showed up.

The random variable X follows a Binomial distribution with parameters <em>n</em> = 53 and <em>p</em> = 0.96.

As there are only 50 sets available, the restaurant can accommodate all the customers who do show up if and only if 50 or less customers showed up.

Compute the probability that the restaurant can accommodate all the customers who do show up as follows:

P(X\leq 50)=1-P(X>50)\\=1-P(X=51)-P(X=52)-P(X=53)\\=1-[{53\choose 51}(0.96)^{51}(0.04)^{53-51}]-[{53\choose 52}(0.96)^{52}(0.04)^{53-52}]\\-[{53\choose 53}(0.96)^{53}(0.04)^{53-53}]\\=1-0.27492-0.25377-0.11491\\=0.3564

Thus, the probability that the restaurant can accommodate all the customers who do show up is 0.3564.

Hi guys please let me know if im correct :(((
jasenka [17]

Answer:

104F

Step-by-step explanation:

I'm not 100% sure if this is correct but here is how I did it:

I assume we are using the equation provided in the question to find the Fahrenheit.

C represents Celsius degrees and F represents Fahrenheit degrees in the equation.

The question gives us 40 degrees Celsius

I substitute the 40C into the C in the equation and then find F which is the answer: 40= \frac{5}{9} (F-32)
