Answer:
And using the probability mass function we got:
And adding the values we got:
The best answer would be:
D. 0.377
Step-by-step explanation:
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
For this case in order to pass he needs to answer at leat 6 questions and we can rewrite this:
And using the probability mass function we got:
And adding the values we got:
The best answer would be:
D. 0.377
Answer:
22 units.
Step-by-step explanation:
In 45- 45- 90 triangles, there is a 1 to 1 to the square root of 2 formula. Each side length measures 1x, while the hypotenuse measures x times the square root of 2.
In this case, the hypotenuse measures 22 and the square root of 2 units. To find the value of x, simply divide that by the square root of 2 units, and you get x = 22 units. Multiply that by 1, and you get 22 units, which is the length of the leg of the triangle.

Answer:
5
Step-by-step explanation:
Hope this helps :)
Supplementary angles add up to 180 degrees
The value of x is 17
The given parameters are:
Because the angles are supplementary, then:
So, we have:
Collect like terms
Divide both sides by 8
Hence, the value of x is 17

Answer:
17
Step-by-step explanation:
12.5 - (-4.5) = 12.5 + 4.5 = 17
