Let I = the event that a player is an infielder.

Let 0 = the event that a player is an outfielder

Let H = the event that a player is a great hitter.

Let N = the event that a player is not a great hitter.


Write the symbols for the probability that of all the great hitters, a player is an outfielder.

Answers

Answer:

P(H | I)

Step-by-step explanation:

Given that

Some players considered to be great hitters and some would be not great htters

So based on the symbols given in the question

For all the great hitters a player would be an outfielder

For this the symbol is

P(H | I)

The probability that of all the great hitters, a player is an outfielder will be [tex]P(O\cap H)[/tex].

Given information:

On a baseball team, there are infielders and outfielders. Some players are great hitters, and some players are not great hitters.

Lets assume,

I = the event that a player is an infielder. 0 = the event that a player is an outfielder. H = the event that a player is a great hitter. N = the event that a player is not a great hitter.

It is required to write the probability that of all the great hitters, a player is an outfielder.

It is required that the player should be outfielder and hitter both.

So, the required probability can be written as,

[tex]P(O\cap H)[/tex]

Therefore, the probability that of all the great hitters, a player is an outfielder will be [tex]P(O\cap H)[/tex].

Ani spent a total of $7.53 at a store. She bought some cereal for $3.67. She also bought 6 peaches.
If each peach cost the same amount, which equation can be used to find the cost of each peach, P?
A. P = $7.53-6
B. P = $3.67 6
C. P= $7.53 - ($3.67=0
D. P= ($7.53 - $3.67) = 6
E. P= ($7.53 + $3.67) = 6

Answers

Answer:

D

Step-by-step explanation:

It says she spent $7.53 at the store and she bought (SOME) cereal for $3.67

so we have to find how much the 6 peaches cost. To find it out we are going to have to subtract the cereal she bought from $3.67 and the money she wasted total so its going to be D.

Step-by-step explanation:

If the perimeter is 56 cm..

x - 1 + 3x + 3x + 1 = 56

7x = 56

x=8

The x - 1 side = 7

The 3x = 1 side - 25

The ex side = 24

The area of a triangle = base time height divided by 2.

So...

x-1 times 3x divided by 2 is your equation.

Answer:

503 inches (rounded to the nearest whole number)

Step-by-step explanation:

First, we must calculate the wheel's circumference, or in other words, the distance around the wheel. We can do this by using the below equation:

[tex]C=\pi d[/tex] when [tex]d[/tex] is the diameter

Because we know that the wheel's diameter is 16 inches, we can plug it into the equation:

[tex]C=\pi (16)\\C=16\pi[/tex]

Now, because we know that the wheel makes 10 revolutions, we calculate the distance it travelled by multiplying the circumference by 10.

[tex]16\pi *10\\= 160\pi[/tex]

[tex]= 503[/tex] inches when rounded to a whole number

Therefore, the wheel travelled approximately 503 inches.

Select the correct answer. What is the range of function m? m(x) = √x - 3 + 1​

Answers

Answer:

i think it is b

Step-by-step explanation:

The range for m is [3, ∞)

What is function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

m(x)= √(x- 3) + 1

For x= 0

m(0) = √(-3) + 1

m(0) = √3i + 1

So, m ≠ 0, 1, 2 because it leads to imaginary value.

Thus, m ≥ 3

i.e., m=4

m(3)= √3-3 + 1= 1

and, m(4)= √(4- 3)+ 1 = 2

Hence, the range for m is [3, ∞)

We can find the slope by using 2 coordinates that are on a line.

We can choose any of the coordinates from this table. I'm gonna use (0, 4) and (2, 5)

The formula for find the slope is the rise over the run or

4 - 5 / 0 - 5

-1 / -5

The slope is 1/5

Geometry problem above^^^ In the figure at the right FGH ~ KLJ....

Answers

Answer:

x = 12

y = 4.5

Step-by-step explanation:

Since ∆FGH ~ ∆KLJ, therefore, we would have the following proportion:

[tex] \frac{FG}{KL} = \frac{GH}{LJ} = \frac{FH}{KJ} [/tex]

[tex] \frac{9}{y} = \frac{x}{6} = \frac{6}{3} [/tex]

✔️Let's solve for x using:

[tex] \frac{x}{6} = \frac{6}{3} [/tex]

Multiply both sides by 6

[tex] \frac{x}{6}*6 = \frac{6}{3}*6 [/tex]

[tex] x = \frac{6*6}{3} [/tex]

[tex] x = 12 [/tex]

✔️Solve for y using:

[tex] \frac{9}{y} = \frac{6}{3} [/tex]

Cross multiply

[tex] y*6 = 3*9 [/tex]

6y = 27

y = 27/6

y = 4.5

Find the value of x.​

Answers

Answer:

30 degrees

Step-by-step explanation:

The computation of the value of x is given below:

Given that

ADC = 120 degrees

So ABC = 60 degrees

As the sum of the opposite angles are 180 degrees

And ACB = 90 degrees

Now in Triangle ADC

Angle ACB + Angle ABC + x = 180 degrees

90 + 60 + x = 180

x = 30 degrees

The answer is y = x - 5

Sub in 0 to find the y intercept, and count rise over run to find the slope (1)

Answer:

y = 1x + -5

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

the line touches the y-axis at -5, therefore the y-intercept, or b, is -5.

y = mx + b ⇒ y = mx - 5

now i'll find the slope by picking two points from the line and finding the change in y over the change in x, aka [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. i'll use the points (8, 3) and (5, 0)  from the line in order to calculate the slope. (8, 3) can be my [tex]x_2[/tex] and [tex]y_2[/tex] and (5, 0) can be my [tex]x_1[/tex] and [tex]y_1[/tex].

first, i'm going to plug in my [tex]y_2[/tex] and [tex]y_1[/tex] values, which are the y-values from each of the coordinate pairs. since i picked (8, 3) for [tex]x_2[/tex] and [tex]y_2[/tex] and (5, 0) for [tex]x_1[/tex] and [tex]y_1[/tex], i will be plugging in 3 for [tex]y_2[/tex] and 0 for [tex]y_1[/tex].

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] ⇒ [tex]\frac{3-0}{x_2-x_1}[/tex]

then i'll plug in my [tex]x_2[/tex] and [tex]x_1[/tex] values, which will be 8 and 5.

[tex]\frac{3-0}{x_2-x_1}[/tex] ⇒ [tex]\frac{3-0}{8-5}[/tex]

now simplify by subtracting 0 from 3 and 5 from 8.

3 - 0 = 38 - 5 = 3

the slope is [tex]\frac{3}{3}[/tex], which simplifies to 1 because [tex]\frac{3}{3}[/tex] or  3 ÷ 3 = 1.

the slope-intercept form equation for this line is y = 1x + -5 (or just y = x - 5, but since it's a fill-in-the-blank problem, the 1 will show in front of the y and -5 will come after the + sign.)
