The probability that the first card is a king and the second card is not a king is 0.0045
Suppose two cards are drawn sequentially so that one random circumstance is the result of the first card drawn and the second random circumstance is the result of the second card drawn. To find the probability that the first card is a king and the second card is not a king.
In the first case let's find the probability of drawing a king from the deck of cards,
A = ( 4/52 )
In the second case the probability of drawing a card that is not a king from the deck is,
B = ( 3/51 )
At last, to get the final probability to draw that the first card is a king and the second card is not a king we need to multiply the above two cases as,
A x B = ( 4/52 ) ( 3/51 )
= 1/221
= 0.0045
The probability that the first card is a king and the second card is not a king is 0.0045

Graph the Linear equation: y = - 3/4x + 5
Answers
Based on the given linear equation of y = - 3/4x + 5, the graph is shown attached.
How to graph an equation?When given a linear equation, you graph it by coming up with x values and then using the equation to find the corresponding y values.
The linear equation is y = - 3/4x + 5.
If the value x = -1, then y would be:
y = - 3/4x + 5
= -3/4(-1) + 5
= 5.75
If the value x = 0, then y would be:
y = -3/4(0) + 5
= 5
If the value x = 1, then y would be:
= -3/4(1) + 5
= 4.25
If the value x = 2, then y would be:
= -3/4(2) + 5
= 3.5
If the value x = 3, then y would be:
= -3/4(3) + 5
= 2.75
The points would be:

Beth is planning a playground and has decided to place the swings in such a way that they are the same distance from the jungle gym and the monkey bars. if beth places the swings at point d, how could she prove that point d is equidistant from the jungle gym and monkey bars? if segment ad ≅ segment cd, then point d is equidistant from points a and b because congruent parts of congruent triangles are congruent. if segment ad ≅ segment cd, then point d is equidistant from points a and b because a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects. if m∠acd = 90° then point d is equidistant from points a and b because congruent parts of congruent triangles are congruent. if m∠acd = 90° then point d is equidistant from points a and b because a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects.
Answers
The angle bisector theorem states that a triangle's opposite side is divided into two halves by an angle bisector that is proportional to the triangle's other two sides.
A point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects, therefore if mACD = 90°, point D is equidistant from points A and B.
Any point on the perpendicular bisector is simply equal distance from both endpoints of the line segment on which it is drawn, according to the perpendicular bisector theorem.
The answer is that point is equidistant from points A and B because a point on a perpendicular bisector is equidistant from the endpoints of the segment it makes up. Therefore, if a pillar is stationed at the middle of a bridge at an angle, all the points on the pillar will be equidistant from the end points of the bridge intersects.

The Beta club is selling chocolate to raise money for Beta convention. Chocolate bars sell for $1.25 each and chocolate covered almonds sell for $2.00 each. The Beta club needs to raise more than $375 for all members to attend the convention. The students can sell up to 500 bars and covered almonds altogether.
1. Write a system of inequalities that can be used to represent this situation.
2. The club sells 100 chocolate bars. What is the least number of chocolate covered almonds that must be sold to cover the cost of attending Beta convention? Justify your answer.
Answers
(1) The system of inequalities that can be used to represent this situation is 1.25x + 2y > 375 and x+y ≤ 500 .
(2) The least number of chocolate covered almonds that must be sold to cover the cost of attending Beta convention is 126 .
In the question ,
Part(1)
let the number of chocolates be "x" .
let the number of chocolates with covered almonds be "y"
price of each chocolate bar = $1.25
price of each chocolate covered almonds = $2
Beta club needs more than $375
So , according to the question
1.25x + 2y > 375
and also the students can sell up to 500 bars and covered almonds altogether.
So , x+y ≤ 500 .
Part(2)
Given , the club sells 100 chocolate bars.
substituting x= 100 in the inequality 1.25x + 2y > 375 , we get
1.25(100) + 2y > 375
125 + 2y > 375
2y > 375-125
2y > 250
y > 125
least number of chocolate covered almonds to be sold is 126 .
Therefore , (1) The system of inequalities that can be used to represent this situation is 1.25x + 2y > 375 and x+y ≤ 500 .
(2) The least number of chocolate covered almonds that must be sold to cover the cost of attending Beta convention is 126 .

In other words, an equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The equation can be solved as follows:
The equation will have the same solution as x = 5.
Therefore,
25 / x + 4 = 9
subtract 4 from both sides of the equation
25 / x + 4 = 9
25 / x + 4 - 4 = 9 - 4
25 / x = 5
cross multiply
5x = 25
divide both sides by 5
x = 25 / 5
x = 5
x / 5 + 5 = 6
x / 5 = 6 - 5
x / 5 = 1
cross multiply
x = 5
32 - 4x = 12
- 4x = 12 - 32

divide both sides of the equations by - 4
x = -20 / - 4
