What is the probability of NOT drawing a face card from a standard deck of 52 cards.
8 over 13
3 over 13
10 over 13

Answers
The probability of NOT drawing a face card from a standard deck of 52 cards is 10 over 13.
First determine the total number of face cards and non-face cards in a standard deck of 52 cards. In a standard deck, there are 12 face cards (3 face cards per suit: Jack, Queen, and King, and 4 suits: Hearts, Diamonds, Clubs, and Spades). This means there are 52 - 12 = 40 non-face cards.
Now, we'll calculate the probability of NOT drawing a face card:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
Probability of NOT drawing a face card = (Number of non-face cards) / (Total number of cards)
Probability = 40 / 52
Simplify the fraction by dividing the numerator and denominator by their greatest common divisor (4):
Probability = (40/4) / (52/4)
Probability = 10 / 13
So, the probability of NOT drawing a face card from a standard deck of 52 cards is 10/13. Your answer: 10 over 13.

We need to read the graph and see which statement describes the function.
We will see that the correct option is A: "The function is negative when x < 0"
First let's see the important things of the graph:
At x near zero, in the positive side, the function tends to infinity.At x near zero, in the negative side, the function tends to negative infinity.As the absolute value of x increases, the function tends to zero.Then we know that this is an inverse function like:
y = f(x) = 1/x
Now let's see which statement correctly describes the function:
A) The function is negative when x < 0.
This is true, you can see that when x < 0, the function is below the horizontal axis, thus for x < 0 the function is negative.

solve the equation 1 = 6 (1 - p)
Answers
Answer:
p = 0.8333333333
Step-by-step explanation:
Simplifying
1 = 6(1 + -1p)
1 = (1 * 6 + -1p * 6)
1 = (6 + -6p)
Solving
1 = 6 + -6p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '6p' to each side of the equation.
1 + 6p = 6 + -6p + 6p
Combine like terms: -6p + 6p = 0
1 + 6p = 6 + 0
1 + 6p = 6
Add '-1' to each side of the equation.
1 + -1 + 6p = 6 + -1
Combine like terms: 1 + -1 = 0
0 + 6p = 6 + -1
6p = 6 + -1
Combine like terms: 6 + -1 = 5
6p = 5
Divide each side by '6'.
p = 0.8333333333
Answer:
0.833
Step-by-step explanation:
Simplifying
1 = 6(1 + -1p)

We are given a triangle. One of the angles is 122 degrees, as shown in the diagram. We need to find all the interior and exterior angles. The vertically opposite angles are equal. The angle ∠4 is vertically opposite to the given angle. So, ∠4 = 122°. The angle ∠5 and the given angle form a linear pair. So, the angle ∠5 = 180° - 122° = 58°. The angle ∠6 is vertically opposite to the angle ∠5. So, the angle ∠6 = 58°. The angles ∠1, ∠2, and ∠3 are angles made by coordinate axes that are perpendicular to each other. So, the angles ∠1 = ∠2 = ∠3 = 90°. Now we use the angle sum property of a triangle. The sum of all the interior angles of a triangle is 180°. So, we can write the equation : ∠6 + ∠1 + ∠8 = 180°. So, ∠8 = 180° - (∠6 + ∠1) = 180° - (58° + 90°) = 180° - 148° = 32°. The angles ∠8 and ∠9 form a linear pair. So, ∠9 = 180 - 32° = 148°. The angle ∠7 is vertically opposite to the angle ∠9. So, the angle ∠7 = 148°.

Answers
The probability that the person will be cured of back pain is 2/7.
The probability that a person will be cured of back pain after being given a sugar pill can be determined by using the given information in the question. According to the question, for every 2 patients cured by the sugar pill, 5 patients were not cured by the sugar pill. This means that out of a total of 2 + 5 = 7 patients given the sugar pill, only 2 were cured. Therefore, the probability of a patient being cured of back pain after being given a sugar pill is 2/7.
To calculate the probability, we can use the formula:
P(cured) = number of patients cured / total number of patients
Plugging in the given values, we get:
P(cured) = 2 / 7
Therefore, the probability that a patient will be cured of back pain after being given a sugar pill is 2/7.
In conclusion, according to the results of the study, if a patient is given a sugar pill, the probability that the person will be cured of back pain is 2/7.

according to a recent study from the centers for disease control on american adults, the proportion that have a mobile phone is 89%, the proportion that have a landline is 57%, and 2% have neither a landline nor a mobile phone. what proportion of american adults have a mobile phone, and not a landline?
Answers
Approximately 34% of American adults have a mobile phone but not a landline, based on the given proportions from the study conducted by the Centers for Disease Control.
The proportion of American adults who have a mobile phone but not a landline, we need to subtract the proportion of those who have both a mobile phone and a landline from the proportion of those who have a mobile phone.
Let's denote the proportion of American adults who have a mobile phone as P(M), the proportion who have a landline as P(L), and the proportion who have neither as P(N).
Given information:
P(M) = 89% (proportion with a mobile phone)
P(L) = 57% (proportion with a landline)
P(N) = 2% (proportion with neither)
We can now calculate the proportion of adults who have a mobile phone but not a landline using the following equation:
P(M and not L) = P(M) - P(M and L)
To find P(M and L), we can subtract P(N) from P(L) since those who have neither are not included in the group with a landline:
P(M and L) = P(L) - P(N)
P(M and L) = 57% - 2%
P(M and L) = 55%
Now we can substitute the values back into the equation to find P(M and not L):
P(M and not L) = P(M) - P(M and L)
P(M and not L) = 89% - 55%
P(M and not L) = 34%

Surface area of the cone below is about 151.58 in.² the radius of the base is 4 inches what is the slant height using 3.14 for pi round your answer to the nearest whole number
Answers
Answer:
surface area of cone= πr²+πrl
151.58=3.14×4×4+3.14×4×l
151.58=50.24+12.56×l
151.58=62.8×l
62.8 62.8
l= 2.414
The slant height of the cone is approximately 8 inches when the surface area is about 151.58 in², and the radius of the base is 4 inches.
The formula for surface area of cone:
Surface Area = πr(r + l)
Given that the surface area is 151.58 in².
Radius (r) is 4 inches.
Substitute these values into the formula and solve for the slant height:
\(151.58 = 3.14 \times 4(4 + l)\)
\(151.58 = 12.56 \times (4 + l)\)
\(151.58=50.24+12.56l\)
Substitute 50.24 from both sides:
\(151.58-50.24 = 12.56l\)
\(101.34= 12.56l\)
Divide both sides by 12.56:
\(l=8.07\)
Slant height = 8 inches.
Hence, the slant height is 8 inches.

(Draw a diagram to help you!) cm
Answers
The subtended arc for the second circle is 31.2 cm long.
Given a circle with a radius of 6 cm and a subtended arc of 15.6 cm, we can find the angle's measure in radians using the formula: angle (in radians) = arc length/radius. Plugging in the values, we get angle = 15.6 cm / 6 cm = 2.6 radians.
For the second circle with a radius of 12 cm, we can find the subtended arc length by rearranging the formula: arc length = angle (in radians) * radius. Using the angle of 2.6 radians, we get arc length = 2.6 radians * 12 cm = 31.2 cm. Therefore, the subtended arc for the second circle is 31.2 cm long.
