Answer:

1/2 chance

Step-by-step explanation:

A cube has 6 sides. 1, 2, 3, 4, 5, 6.

2, 3, and 5 are primes.

3/6=1/2.

Answer:

e = -1/2

Step-by-step explanation:

4/3 = -6e - 5/3

transfer -6e to the right

4/3 = -5/3 -6e

Find the LCM of 3,3and 1

and their LCM is 3. So, divide all through by 3

3(4/3) = 3(-5/3) - 6e × 3

4 = -5 -18e

combine

4 + 5 = -18e

9 = -18e

divide by -18

9/ -18 = -18e/ -18

-1/2 = e

e = -1/2

Which of the following equations can be used to find the length of angle LN in the triangle below?

shtirl [24]

Answer:

Option A. $LN^{2}=33^{2}-11^{2}$

Step-by-step explanation:

we know that

In the right triangle MNL

Applying the Pythagoras Theorem

$MN^{2}=ML^{2} +LN^{2}$

substitute the values

$33^{2}=11^{2} +LN^{2}$

$LN^{2}=33^{2}-11^{2}$

Assume that the Poisson distribution applies and that the mean number of aircraft accidents is 9 per month. Find P(0), the prob

Ugo [173]

Answer: 0.0001

It is unlikely to have a month with no aircraft accidents .

Step-by-step explanation:

Given : Mean number of aircraft accidents = 9 per month

The Poisson distribution formula :-

$\dfrac{e^{-\lambda}\lambda^x}{x!}$ , where $\lambda$ is the mean of the distribution.

If X = the number of aircraft accidents per month, then the probability that in a month, there will be no aircraft accidents will be :-

$\dfrac{e^{-9}(9)^0}{0!}=0.000123409804087\approx0.0001$

Hence, the probability that in a month, there will be no aircraft accidents = 0.0001

Since this is less than 0.5 , therefor it is unlikely to have a month with no aircraft accidents .

Please anyone help me The measure of an angle is five times the measure of its supplementary angle. What is the measure of each

Radda [10]

Answer:

150 and 30

Step-by-step explanation:

Hello!

Supplementary angles are angles that when added up equal 180

Which can be shown by

x + x = 180

Since one has to be 5 times bigger we put a 5 in front of one of the x's

5x + x = 180

5x is an angle and x is the other

Now we solve for x

5x + x = 180

Combine like terms

6x = 180

Divide by 6

x = 30

Now we put that into each angle

5(30) = 150

The answer is 150 and 30

Hope this Helps!
