Answer: The probability is 1/52 or .0192.
Step-by-step explanation:
A standard deck of cards has 52 so the probability of picking 1 card would be 1/52.
(a) The probability of drawing a spade is 1/4.
(b) The probability of drawing a face card (jack, queen, or king) is 3/13.
(c) The probability of drawing a red card is 1/2.
(d) The probability of drawing a card that is not an ace is 12/13.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
(a) The probability of drawing a spade.
There are 13 spades in a standard deck of 52 cards, so the probability of drawing a spade is:
P(spade) = 13/52 = 1/4
(b) The probability of drawing a face card (jack, queen, or king).
There are 12 face cards (4 jacks, 4 queens, and 4 kings) in a standard deck of 52 cards, so the probability of drawing a face card is:
P(face card) = 12/52 = 3/13
(c) The probability of drawing a red card.
There are 26 red cards (13 hearts and 13 diamonds) in a standard deck of 52 cards, so the probability of drawing a red card is:
P(red card) = 26/52 = 1/2
(d) The probability of drawing a card that is not an ace.
There are 48 cards that are not aces in a standard deck of 52 cards (there are 4 aces), so the probability of drawing a card that is not an ace is:
P(not ace) = 48/52 = 12/13
Thus,
(a) The probability of drawing a spade is 1/4.
(b) The probability of drawing a face card (jack, queen, or king) is 3/13.
(c) The probability of drawing a red card is 1/2.
(d) The probability of drawing a card that is not an ace is 12/13.

Which of the following coordinate points is the point of intersection of these two lines? y - 6x = -4 y - 2x = 8 Question 4 options: (−1/2, 7) (12/8,11) (9/6,5) (3, 14)
Option D: [tex](3,14)[/tex] is the point of intersection of the two lines.
Explanation:
The two equations are [tex]y-6 x=-4[/tex] and [tex]y-2 x=8[/tex]
We need to find the point of intersection of the two lines.
Thus, let us solve the equation by substitution method.
From the equation [tex]y-6 x=-4[/tex], we shall determine the value of y, by adding both sides of the equation by 6x.
Hence, we have, [tex]y=6x-4[/tex]
Now, substituting [tex]y=6x-4[/tex] in the equation [tex]y-2 x=8[/tex] , we get,
[tex]6x-4-2 x=8[/tex]
[tex]4x-4=8[/tex]
[tex]4x=12[/tex]
[tex]x=3[/tex]
Substituting [tex]x=3[/tex] in the equation [tex]y-6 x=-4[/tex], we get,
[tex]y-2 (3)=8[/tex]
[tex]y-6=8[/tex]
[tex]y=14[/tex]
Thus, the point of intersection of the two lines is [tex](3,14)[/tex]
Therefore, Option D is the correct answer.
Find the range f(x) =-2x-5 for the domain (-2,-1,1,2).
Answer:
{ - 9, - 7, - 3, - 1 }
Step-by-step explanation:
To obtain the range substitute the values of x from the domain into f(x)
f(- 2) = - 2(- 2) - 5 = 4 - 5 = - 1
f(- 1) = - 2(- 1) - 5 = 2 - 5 = - 3
f(1) = - 2(1) - 5 = - 2 - 5 = - 7
f(2) = - 2(2) - 5 = - 4 - 5 = - 9
range is { - 9, - 7, - 3, - 1 }
Algebra 1, Section 7.09
Answer:
b. 4
Step-by-step explanation:
Given f(x) = 4x - 4 and g(x) = x - 1, we can find (f/g)(x) by dividing f(x) by g(x):
(f/g)(x) = (4x - 4)/(x - 1)
Now, substituting x = -4 into the expression
(f/g)(-4) = (4*(-4) - 4)/((-4) - 1) = (-16 - 4)/(-5) = -20/-5 = 4
Therefore, the correct answer is b. 4.
Given the function g(x) = x - 1, let's solve (f/g)(-4) using the function f(x) = 4x - 4.
To find (f/g)(-4), we need to evaluate the expression (f(x)/g(x)) at x = -4.
First, let's find the value of f(x)/g(x) for any x:
(f/g)(x) = f(x)/g(x) = (4x - 4)/(x - 1)
Now, substituting x = -4 into the expression:
(f/g)(-4) = (4(-4) - 4)/((-4) - 1) = (-16 - 4)/(-5) = -20/-5 = 4
Therefore, the correct answer is b. 4.

A utility pole is supported by two wires, one on each side, going in the opposite direction. The two wires form a 75-degree angle at the utility pole. if the wires are 12 meters and 16 meters long and secured to the ground, find the distance between the wires on the ground.
(Cosines problem)
Answer:
The required distance is 17.34 meters.
Step-by-step explanation:
The lengths of the two wires are 12 meters and 16 meters. and the angle between the wires is 75°.
Now, we have to calculate the distance between the wires on the ground.
Therefore, we have to calculate the length of the side which is the opposite side of angle 75° of the triangle formed by the wires and the ground.
Applying the formula of properties of the triangle, if the length required is x, then
[tex]\cos 75^{\circ} = \frac{12^{2} + 16^{2} - x^{2}}{2 \times 12 \times 16}[/tex]
⇒ 99.38 = 144 + 256 - x²
⇒ x = 17.34 meters. (Answer)

I want to buy a combination of Dr.pepper and sprite. dr pepper cost 2.98 each and sprite is on sell for 1.99 each. I need at least 8 total and i can spend more than 20 dollars
High School
There are quite a few possible combinations that are minimum 8 sodas, and under $20.
1. 4 Dr. Peppers and 4 Sprites. $2.98 times 4 = $11.92. $1.99 times 4 = $7.96. $7.96 + $11.92 = $19.88.
2. 3 Dr. Peppers and 5 Sprites. $2.98 times 3 = $8.94. $1.99 times 5 = $9.95. $9.95 + $8.94 = $18.89.
3. 2 Dr. Peppers and 6 Sprites. $2.98 times 2 = $5.96. $1.99 times 6 = $11.94. $11.94 + $5.96 = $17.90.
4. 2 Dr. Peppers and 7 Sprites. $2.98 times 2 = $5.96. $1.99 times 7 = $13.93. $5.96 + $13.93 = $19.89.
5. 1 Dr. Pepper and 7 Sprites. $2.98 times 1 = $2.98. $1.99 times 7 = $13.93. $2.98 + $13.93 = $16.91.
6. 1 Dr. Pepper and 8 Sprites. $2.98 times 1 = $2.98. $1.99 times 8 = $15.92. $15.92 + $2.98 = $18.90.

Katie has 6500 in her savings account. If it earns 6% interest every month how much savings does she have in her account in over half a year
Step-by-step explanation:
First, you recognize the algorithm for the equation: A=P(1+r)^n. This is the algorithm for interest. P is the amount of initial money (in this case, 6500), r is the interest rate (6%, or 0.06), and n is the number of times it is being compounded. Since half a year is given to me, 6 months is what I will be using, or just 6.
Next, plug in the numbers. The equation is now: A=6500(1+0.06)^6.
Now time to solve. First add what's in the parenthesis, and put it to the power of 6, for 6 months. Then multiply that amount to the initial dollar amount; 6500. This will leave you with 9,220.37.
The length of a rectangle is the sum of the width and 1. The area of the rectangle is 20 units. What is the width, in units, of the rectangle?
Width of the rectangle is 4 units
Step-by-step explanation:
Step 1: Let the width of the rectangle be x. Then the length = x + 1. Find dimensions if area = 20 sq. unitsArea of the rectangle = length × width
⇒ 20 = x (x + 1)
⇒ 20 = x² + x
⇒ x² + x - 20 = 0
⇒ x² + 5x - 4x - 20 = 0 (Using Product Sum rule to factorize)
⇒ x(x + 5) - 4(x + 5) = 0
⇒ (x + 5)(x - 4) = 0
⇒ x = -5, 4 (negative value is neglected)
x = 4
Final answer:
The solution reveals that the width of the rectangle is 4 units.
Explanation:
The student is asking to find the width of the rectangle when the length is given as the sum of the width and 1 unit, and the area of the rectangle is 20 square units.
To solve this, we can set up an equation using the area formula for a rectangle, A = length * width, where the area (A) is 20 square units.
Let's denote the width as w units.
Then the length can be expressed as w + 1 units. Substituting these expressions into the area formula gives us:
20 = w * (w + 1)
Expanding the right side, we get:
20 = w² + w
This is a quadratic equation, which we can solve by setting it equal to zero:
w² + w - 20 = 0
Factoring the quadratic equation, we find:
(w + 5)(w - 4) = 0
Therefore, w could be -5 or +4. Since a width cannot be negative, the only reasonable solution is w = 4 units.
Thus, the width of the rectangle is 4 units.

B
157 cm
C
D
56.251 cm
2257 cm
The radius of the circle is approximately 7.5 cm, and the corresponding area is approximately 56.25π cm², as calculated using the formulas for circumference and area. Here option C is correct.
1: Find the radius using the circumference formula
We know the circumference C = 157 cm.
We also know the formula for circumference of a circle: C = 2πr, where r is the radius.
Rearranging the formula to solve for r, we get: r = C / (2π).
Substituting C with 157, we get: r = 157 / (2π) ≈ 7.5 cm.
2: Calculate the area using the area formula
Now that we know the radius, we can use the formula for the area of a circle: A = πr², where A is the area.
Substituting r with 7.5, we get: A = π * (7.5)² ≈ 56.25π cm².
Therefore, the area of the circle is 56.25π cm². Here option C is correct.
