Answer:

  10 ft

Step-by-step explanation:

The midsegment length is the average of the other two lengths.

  (QR +PS)/2 = TU

  QR +PS = 2×TU . . . . . . . . . . . . . . . multiply by 2

  QR = 2×TU -PS = 2(14 ft) -18 ft . . . subtract PS; substitute given values

  QR = 10 ft

Is 4y - 8 > 10 true?
steposvetlana [31]

4y-8>10

Add 8

4y-8+8>10+8

4y>18

Now divide both sides by 4

4y/4 > 18/4

y>9/2


Now let's see if it will be true

Replace y by its value

4(9/2)-8>10

36/2 -8 > 10

18-8 > 10

10 > 10

That's false because 10 can not smaller than 10

so it should be = instead


Answer : False


I hope that's help:)

The number of typing errors made by a typist has a Poisson distribution with an average of five errors per page. If more than fi
xeze [42]

Answer:

0.61596

Step-by-step explanation:

Given that:

λ = 5 (5 errors per page)

Poisson distribution formula :

P(x = x) = (λ^x * e^-λ) / x!

Probability that page does not need to be retyped means that error on page is less than or equal to 5

P(x ≤ 5) = p(x = 5) + p(x = 4) +... + p(x = 0)

The individual probabilities can be obtained using the formula above or the use of a calculator

P(x ≤ 5) = 0.17547 + 0.17547 + 0.14037 + 0.08422 + 0.03369 + 0.00674

P(x ≤ 5) = 0.61596
