What is P(Not A | Not B )?
The calculated value of the conditional probability P(Not A | Not B) is 0.8125
How to calculate the probability P(Not A | Not B )?From the question, we have the following parameters that can be used in our computation:
The table of values
The probability P(Not A | Not B ) is calculated as
P(Not A | Not B ) = (Not A and Not B)/(Not B)
Using the above as a guide, we have the following:
(Not A and Not B) = 0.65
(Not B) = 0.80
Substitute the known values in the above equation, so, we have the following representation
P(Not A | Not B ) = 0.65/0.80
Evaluate
P(Not A | Not B) = 0.8125
Hence, the probability P(Not A | Not B) is 0.8125

Which describes the value of a?
Answer:
(c) 0 < a < 1
Step-by-step explanation:
You want to know the value of 'a' in y = a·cot(x) that will cause a vertical compression without reflection.
Vertical scalingWhen a function value is multiplied by a factor greater than 1, its graph is expanded vertically. When that factor is less than 1, the graph is compressed, as in the attachment.
If the scale factor is negative, the graph will be reflected across the x-axis.
Here, you want compression without reflection. That requires a positive scale factor less than 1.
0 < a < 1

The angle that has been formed and is shown as x is shown as 52.1°.
What is the angle x?In a right triangle, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. The tangent function is denoted as tan.
We can see that we need to find the tangent of the angle;
Tan x = 36/28
x = Tan-1(36/28)
x = 52.1°
Thus it is clear from the calculation that we have done above that the angle that is marked x is 52.1°.

Suppose that 100 unique names are put into a hat and drawn at random without replacement. How many different ways can you draw all of the names from the hat? Remember that "without replacement" means that the names are not returned to the hat after they are chosen. Write your answer in factorial notation.
The solution is: 100! different ways can you draw all of the names from the hat.

if we have n object, and as we know that arrangement given by = n!. (Permutation)
A permutation is a mathematical technique for determining the number of possible arrangements in a sentence where the order of arrangements is important. A common math problem involves choosing some items in a particular order from a set of items.
A permutation also called an "order number" or "sequence", is the rearrangement of the elements of an ordered list so that they correspond one-to-one with themselves. (Faculty; Ouspensky 1937, p. 18). Permutations are said to be ordered combinations. The number of permutations r of n objects acquired simultaneously is determined by the following formula: P(n,r)=n!(n-r)!
Hereafter taking each unique name, we will arrange it in raw, so we can say this problem is equivalently permutation problem, So we can say the way of drawing all names can be done in 100! Way.

Determine the equation of the cirele with center (2, 3) containing the point (7, 15).
Answer:
IG: yiimbert
The equation of a circle with center (h, k) and radius r is given by:
(x - h)^2 + (y - k)^2 = r^2
We are given that the center of the circle is (2, 3) and it contains the point (7, 15). To find the radius, we can use the distance formula between the center and the given point:
r = sqrt[(7 - 2)^2 + (15 - 3)^2]
r = sqrt[25 + 144]
r = sqrt(169)
r = 13
Substituting the given values into the equation of a circle, we get:
(x - 2)^2 + (y - 3)^2 = 13^2
Expanding the terms, we get:
x^2 - 4x + 4 + y^2 - 6y + 9 = 169
Simplifying and rearranging, we get:
x^2 - 4x + y^2 - 6y = 156
Therefore, the equation of the circle with center (2, 3) containing the point (7, 15) is:
x^2 - 4x + y^2 - 6y = 156
You start driving west for 20 miles, turn left, and drive south for another 14 miles. At the end of driving, what is your straight line distance from your sta
rting point? Round to the nearest tenth of a mile.
The straight-line distance from your starting point at the end of driving is approximately 24.4 miles.
To find the straight-line distance from your starting point, we can use the Pythagorean states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
The distance you drove west and turned left forms two sides of a right triangle, and the straight-line distance from the starting point will be the hypotenuse.
Given:
Distance driven west = 20 miles
Distance driven south = 14 miles
Using the Pythagorean:
Hypotenuse² = (Distance driven west)² + (Distance driven south)²
Hypotenuse² = 20² + 14²
Hypotenuse² = 400 + 196
Hypotenuse² = 596
To find the length of the hypotenuse (straight-line distance), we take the square root of both sides:
Hypotenuse = √596
Hypotenuse ≈ 24.4 miles (rounded to the nearest tenth)

A bag contains seven balls labeled 1 through 7. One ball will be randomly picked. What is the probability of picking an off number? Write your answer as a fraction in simplest form.
Answer:
The odd numbers between 1 and 7 are 1, 3, 5, and 7. There are four of them.
The total number of balls in the bag is 7.
Therefore, the probability of picking an odd number is:
number of odd numbers / total number of balls = 4/7
So the probability of picking an odd number is 4/7

In your dresser, you have 10 pairs of socks, 6 are red, and 7 shorts, 4 of which are sport shorts. If you randomly
reach in and pull out a pair of socks and shorts, what is the probability the socks are red and you have sports
shorts?
The probability of pulling out a red pair of socks and sport shorts is 12/35.
We have,
10 pairs of socks, 6 are red, and 7 shorts, 4 of which are sport shorts.
So, The probability of pulling out a red pair of socks is given by:
= (number of red socks) / (total number of socks)
= 6 / 10
= 3 / 5
and, the probability of pulling out sport shorts is given by:
= (number of sport shorts) / (total number of shorts)
= 4 / 7
To find the probability of both events happening together
= P(red socks) x P(sport shorts)
= (3 / 5) x (4 / 7)
= 12 / 35
Therefore, the probability of pulling out a red pair of socks and sport shorts is 12/35.

find the quotation of-4 1 over 6 and -3 1 over 3
The quotient of -4 1/6 and -3 1/3 is 5/4.
To find the quotient of -4 1/6 and -3 1/3, we need to divide the two mixed numbers. Here's how we can do it:
Step 1: Convert the mixed numbers to improper fractions.
-4 1/6 can be converted to an improper fraction as follows:
-4 1/6 = -25/6
Similarly, -3 1/3 can be converted to an improper fraction as:
-3 1/3 = -10/3
Step 2: Divide the two improper fractions.
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.
So, (-25/6) / (-10/3) becomes (-25/6) * (-3/10).
Step 3: Simplify the resulting fraction.
Multiply the numerators and denominators:
(-25 * -3) / (6 * 10) = 75/60
Step 4: Simplify the fraction, if possible.
The numerator and denominator have a common factor of 15:
75/60 = (5 * 15) / (4 * 15)
Simplifying, we get:
75/60 = 5/4
