I need a little bit of help on this question.

Answer:

4/52 or 1/13 (simplified)

Step-by-step explanation:

There are 4 "10's" in a pack.

This means you have the chance to pick 4 10's.

So out of 52 cards, you can get 4.

4/52 -> Which can be simplified to 1/13.

This is the probability of getting a 10 (once) in a standard deck of cards.

The probability of drawing a 10 from a standard deck of 52 cards is 1/13.

Number of 10's in a standard deck of 52 cards  =4

Total cards =52

Probability is the measurement of the possibilities of events.

P(event) =Favorable outcomes/ Total possible outcomes

Here, Favorable outcomes =4

Total possible outcomes =52

P(10) =4/52

P(10) =1/13

So, the probability of drawing a 10 from a standard deck of 52 cards =1/13

Thus, the probability of drawing a 10 from a standard deck of 52 cards is 1/13

I had the same question on a math test

9514 1404 393

Answer:

  y = -4/3x +23/2

Step-by-step explanation:

The tangent of interest is perpendicular to the radius at the given point on the circle. To find the perpendicular, it helps to know the slope of the radius segment. To find that, we need the center of the circle.

The center of the circle can be found by completing the square for each variable.

  (x^2 -2x) +(y^2 +4y) = 20

  (x^2 -2x +1) +(y^2 +4y +4) = 20 +1 +4

  (x -1)^2 +(y +2)^2 = 25

Comparing this equation to the standard form equation for a circle, we can find the center.

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . . circle of radius r centered at (h, k)

The center of circle P is (1, -2).

The slope m' of the line segment between (1, -2) and (5, 1) is given by ...

  m' = (y2 -y1)/(x2 -x1)

  m' = (1 -(-2))/(5 -1) = 3/4

The slope m of the perpendicular line is the opposite reciprocal of this, so is ...

  m = -1/m' = -1/(3/4) = -4/3

The y-intercept of the desired line can be found from ...

  b = y -mx . . . . . . . for m=-4/3 and (x, y) = (5, 1)

  b = 1 -(-4/3)(5) = 23/3

Then the equation of tangent line AB is ...

  y = mx +b

  y = -4/3x +23/3

Answer:

y = (2/3)x + 19/3

Let me know if there are any parts of the process you do not understand.

Step-by-step explanation:

First you need to know what slope is, if you do not let me know and I can explain it in depth.

Now, you can determine if a line is parallel or perpendicular  by its slope.  parallel has the same slope and perpendicular has the negative reciporical, which basically means negative 1 divided by the slope.  

So if you slope was 3 perpendicular would be -1/3.  if the slope is a fraction you can just flip the fraction and make it negative.  so if the slope is  -2/3 a perpendicular slope would be 3/2, making a negative number negative makes it positive.

Now you start with 2x - 3y = 12.  To find the slope I like putting it in slope intercept form.  basically somethign that looks liek y = mx + b.  to do that just use algebra on what you have to get y by itself.  here is how I would do that.

2x - 3y = 12 first subtract 2x from both sides

-3y = 12 - 2x Now divide both sides by -3

y = 12/-3 - (2x)/3 Now simplify

y = -4 + 2/3 x Now rarrange to make it look like I said, basically you want the x first.

y = 2/3 x - 4

There, so the slope is 2/3.  A parallel line will have the same slope.

To make the equation of a line  you want one point and the slope.  Well we have that, the point is (-2,5) and the slope is 2/3.

To find a line you set up the point slope form.  that is y - y1 = m(x - x1) where m is the slope and x1 and y1 are the coordinates of the point you need.  I will plug all that in.

y - y1 = m(x - x1)

y - 5 = (2/3)(x - (-2))  Now solve

y - 5 = (2/3)x + 4/3

y = (2/3)x + 19/3

So that is the equation of a line parallel to 2x - 3y = 12 that passes through (-2, 5)

Answer:

  A.  6

Step-by-step explanation:

The wording "set A and set B" means you're interested in elements that belong only to both. In your diagram, that is Region II. There are 6 elements that belong to A and B.

  AB = 6

Additional comment

"A and B" is also called the "intersection" of the two sets: A ∩ B.

The number you have chosen is the number in Regions I, II, and III. That is the set of elements that belong to A or B. You have identified the "union" of the two sets: A ∪ B. (It might also be represented as A+B.)

Answer:

y = 9√2

Step-by-step explanation:

By applying Pythagoras theorem in the given right triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

y² = 9² + x²

By the property of isosceles triangle,

Two angles of the right triangle are equal in measure, opposite sides of these equal angles will be equal in measure.

Therefore, x = 9

y² = 9² + 9²

y² = 81 + 81

y² = 162

y = √162

y = 9√2

your answer is 1st quadrant!

Answer:

2.5x = 180

Step-by-step explanation:

106 ° + X° = 180 °  

Solving the above

X° = 180 ° - 106°

X° = 74°

Therefore the value of X° is 2.5°.

B is the correct option

Answer:

  x = 74°

Step-by-step explanation:

The measure of inscribed angle x is half the measure of the arc it intercepts.

  x = 148°/2 = 74°

Answer:

C. No, because the subjects are randomly assigned to treatment groups

Step-by-step explanation:

We are told that 80 people are selected at random and are given the drug gabapentin.

Also that the remaining people are given the placebo.

This means that they are randomly assigned treatment groups and so it is a completely randomized block design and as such the use of volunteers doesn't make it invalid.

Answer:

x=7,−7

Step-by-step explanation:

In order to find the value of x in this quadratic equation we first need to make the equation equal 0 by getting rid of the 140. We do this by subtracting 140 on each side.

3x² - 7 = 140

3x² - 147 = 0

Now we solve as a regular quadratic formula

x= [tex]x = \frac{-(0) +- \sqrt{0^{2} - 4(3)(-147) } }{2(3)}[/tex]

[tex]x = \frac{0 +- \sqrt{1764} }{6}[/tex]

x=7,−7
