Suppose that on the average, 7 students enrolled in a small liberal arts college have their automobiles stolen during the semest
strojnjashka [21]

Answer:0.9991

Step-by-step explanation:

The Poisson distribution probability formula is given by :-

P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}, where \lambda is the mean of the distribution and x is the number of success

Given : \lambda=7

The probability that more than 1 student will have his automobile stolen during the current semester is given by :-

P(x\geq1)=1-P(x=0)=1-(\dfrac{e^{-7}7^0}{0!})\\\\=1-e^{-7}=0.99908811\approx0.9991

Hence, the  probability that more than 1 student will have his automobile stolen during the current semester =0.9991

Which figures demonstrate a translation?
tensa zangetsu [6.8K]

The two bottom graphs demonstrate translations.

<h3>Which figures demonstrate a translation?</h3>

We will have a translation only if:

  • The size of the figure does not change (like in option 1, which we can discard).
  • If the "direction" of the figure does not change, like in option 2, where you can see that there is a reflection.

The images where the figures are only moved a little bit are the ones that demonstrate just a translation, and these are the two lower ones.

If you want to learn more about translations:

NeTakaya

Answer:

  • 157 in²

Step-by-step explanation:

The area of the shape is the sum of three sections

<u>1. Rectangle</u>

  • A = 5*14 = 70 in²

<u>2. Bigger semicircle</u>

  • A = 1/2π(14/2)² = 76.96 ≈ 77 in² (rounded)

<u>3. Smaller semicircle</u>

  • A = 1/2π(5/2)² = 9.8174 ≈ 10 in² (rounded)

<u>Total area:</u>

  • 70 + 77 + 10 = 157 in²
