Answer:

A) 0.072 = 7.2%

B) 8.3333 at-bats (8 to 9 at-bats)

Step-by-step explanation:

A)

If the chance of hitting a home run is 0.12, the chance of not hitting a home run is 1 - 0.12 = 0.88.

To find the probability of the next home run being in the fifth strike, we need the four other strikes to not be a home run, so the probability is:

P = (0.88)^4 * 0.12 = 0.072 = 7.2%

B)

To find the expected number of at-bats until the next home run, we just need to divide 100% by the probability of hitting a home run (0.12 = 12%):

100/12 = 8.3333

So the expected number is 8 to 9 at-bats

In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.
Mnenie [13.5K]

<u>Answer:</u>

The correct answer option for this is: False.

<u>Step-by-step explanation:</u>

We are given the following statement which we are to determine whether its true or false:

<em>In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.</em>

To form a negation, we add the word 'not' to a statement - this part of the given sentence is true.

While 'or take "not" out of a statement if it already exists' is false which makes the whole sentence false.

1. An equation is shown below.
Mila [183]
A) We can first start with the how: our equation is 2x+y=3. First, subtract 2x from each side. We get y=-2x+3. Our Y variable is isolated.
B) Now we can describe which points our equation goes through. One of them is obvious in our form, and that is (0,3) or our y-intercept. Another 2 would be branching off that line, such as (1,1) or (-1,5)
C) To make our system inconsistent, we can easily make another equation, with same slope, but the y-intercept has to be different. Our equation can be y=-2x+2, y=-2x+4, or even y=-2x+3.00000001.

Hope this helps you.

An airplane is 275 miles from the airport to get to it present position the plane flew 125 miles due south from the airport and
Ulleksa [173]

Answer:

(C) 245 miles

Step-by-step explanation:

We can view the starting and ending flight points as the hypotenuse of a right-angle triangle. Since the plane flew 125 miles south, the height of the triangle is 125 and we are given the hypotenuse as 275

If we designate the height as a and the hypotenuse as h, and the base as b then
h² = a² + b²  by the Pythagorean  theorem

or

b² = h² - a² ==> (h + a)(h - a)   {x² - y² = (x + y) (x -y)}

Substituting known values
b² = 275² - 125² = (275 + 125)(275-125) = 400 x 150 = 60,000

b =  √60000 = 244.94 and the closest answer is C: 245 miles
