The probability of getting an ace from a well-shuffled deck of 52 cards is 1/13 and the probability of not getting an ace is 12/13
We can calculate the probability by the following method:
Total number of cards in a pack of cards= 52
Number of ace cards in a pack of cards= 4
Probability of an event= Number of possibilities of that event / Total number of possibilities
(i) If drawing an ace card is considered an event, suppose E, then:
P(E)= Number of ace cards/ Total number of cards
= 4/52
(ii) Probability of any event other than E= 1- Probability of the event E=
If the drawing of a non-ace card is considered an event, suppose E', then
P(E')= 1- the probability of drawing an ace card
= 1- P(E)
= 1-1/13
= (13-1)/ 13
= 12/13

do exponential functions have a vertex?
Exponential functions do not have a vertex.
What is an exponential function?"Exponential function, as its name suggests, involves exponents. An exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
In mathematics, an exponential function is a function of form [tex]f(x) = a^{x}[/tex], where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0."
What is the vertex of a function?"The standard form of a quadratic equation is y = ax² + bx + c and the vertex form of the same is y = a (x - h)² + k. Here, the vertex form has a square in it. So to convert the standard to vertex form we need to complete the square."
We know that, the graph of an exponential function consists of a horizontal asymptote. However, there is no quadratic function available that consists of a horizontal asymptote.
Hence, exponential functions do not have a vertex.

Answer:
7/10 pi (radians)
Step-by-step explanation:
The formula for sector area is (angle * r^2)/2
140pi = angle*r^2/2
multiply both sides by 2
280pi = angle * r^2
r = 20 cm (substitute)
280pi = angle * (20)^2
280pi = angle * 400
Divide both sides by 400
7/10 pi = angle

Stacy has a spinner and a number cube after spinning and rolling the number cube she will add two number what is the probability that the sum of the numbers from the spinner and number cube will be 3 or 4
Complete question :
Stacy has a spinner (1 - 4) and a number cube (1 - 6) after spinning and rolling the number cube she will add two number what is the probability that the sum of the numbers from the spinner and number cube will be 3 or 4
Answer:
5 /24
Step-by-step explanation:
The sample space for the sun of the outcome of the spinner and rolled number cube ;
Sample space = total possible outcomes = 6 * 4 = 24
Required outcome = sum equals 3 or 4 = 5
P(obtaining a sum of 3 or 4) = required outcome / Total possible outcomes
P(obtaining a sum of 3 or 4) = 5 /24

Which describes the cross section of the square prism that passes through the vertices A, B, C, and D shown
Below
Answer:
first of all,
Step-by-step explanation:
In triangle ABC one side equal and two sides equal
Step-by-step explanation:
We are given a prism whose base is square with sides 8 in and height 12 in.
If we take cross section through vertices A, B and C
We will get a cross section as triangle.
In triangle ABC, sides are AB, BC and AC
AB is diagonal of top square whose side 8 in.
AC is face diagonal of front face.
BC is face diagonal of right face.
AC=BC≠AB
Hence, In triangle ABC one side equal and two side equal

If Mrs. Allan's car uses 8 gallons of gas for a 224-mile trip, then, at that rate, how many gallons of gas would the car use for a 560-mile trip?
Answer:
20 gallons of gas
Step-by-step explanation:
Given that :
8 gallons of gas = 224 mile trip
Miles per gallon of Mrs. Allan's car :
Number of miles / gallons of gas
224 miles / 8 gallons
= 28 miles per gallon
Gallons of gas car will use for 560 miles
Number of miles / miles per gallon
560 miles / 28 miles per gallon
= 20 gallons of gas

The three angles of a quadrilateral are 55,73,105 what is the fourth angle
Answer:
x = 127°
Step-by-step explanation:
Let A, B and C be the three angles of a quadrilateral such that they are 55, 73, 105 respectively.
We know that, the sum of angles of a quadrilateral is equal to 360°. Let fourth angle be x.
55+73+105+x = 360
233+x=360
x = 360-233
x = 127°
So, the fourth angle is equal to 127°.
