For the given true statements, what can you conclude using the Law of Syllogism?
If a quadrilateral is a square, then it has four right angles.
If a quadrilateral has four right angles, then it is a rectangle.
A. If a rectangle is a quadrilateral, then it has four right angles.
B. If a quadrilateral has four right angles, then it is a square.
C. If a quadrilateral is a rectangle, then it has four right angles.
D. If a quadrilateral is a square, then it is a rectangle.
Answer: If a quadrilateral is a square, then it is a rectangle. (choice D.)
Step-by-step explanation:
The Law of Syllogism states that if the following two statements are true: If p , then q . If q , then r . Then we can derive a third true statement: If p , then r .
We can apply this rule in the conditional statements:
If a quadrilateral is a square, (p) then it has four right angles. (q)
If a quadrilateral has four right angles, (q) then it is a rectangle. (r)
Therefore:
If a quadrilateral is a square, (p) then it is a rectangle. (r)
I hope this helps!
This conclusion follows directly from the given statements using the Law of Syllogism. C. If a quadrilateral is a rectangle, then it has four right angles. D. If a quadrilateral is a square, then it is a rectangle.
The Law of Syllogism states that if we have two conditional statements and the conclusion of the first statement matches the hypothesis of the second statement, then infer the conclusion of the second statement.
Given the true statements:
If a quadrilateral is a square, then it has four right angles.
If a quadrilateral has four right angles, then it is a rectangle.
use the Law of Syllogism to make conclusions:
A. If a rectangle is a quadrilateral, then it has four right angles.
This conclusion doesn't directly follow from the given statements using the Law of Syllogism.
B. If a quadrilateral has four right angles, then it is a square.
This conclusion doesn't directly follow from the given statements using the Law of Syllogism.
C. If a quadrilateral is a rectangle, then it has four right angles.
This conclusion follows directly from the given statements using the Law of Syllogism.
D. If a quadrilateral is a square, then it is a rectangle.

In Japanese culture, koi fish represent good luck and strength. Ken is redesigning an old
koi pond and uses a pump to drain water from it. The pump runs for 3 hours, removing
an equal number of gallons of water each hour. After 3 hours, the water in the koi pond
has decreased by 948 gallons.
Ken says the water in the pond decreased by 316 gallons each hour. Which
statement best explains why Ken is correct?
A decrease of 316 gallons is represented as 316, and -948 : (-3) = 316 represents the problem.
A decrease of 316 gallons is represented as - 316, and 948 : (-3) = -316 represents the
problem
A decrease of 316 gallons is represented as 316, and 948 : 3 = 316 represents the problem.
A decrease of 316 gallons is represented as - 316, and -948 : 3 = -316 represents the problem.
Done
A decrease of 316 gallons is represented as -316, and -948 : 3 = -316 represents the problem.
FormulasGiven that a pump runs for 3 hours, removing an equal number of gallons of water each hour, and after 3 hours, the water in the koi pond has decreased by 948 gallons, and Ken says the water in the pond decreased by 316 gallons each hour, to determine which statement best explains why Ken is correct, the following calculation must be performed:

Answer:
D. y = 4/3x + 2
Step-by-step explanation:
We will be using the y = mx + b format. The y-intercept is at (0,2) so b is 2. M is calculated by doing rise over run, so in this case, you have to go up 4 and right 3 or 4/3 to get to the next point in the line. Altogether the equation is y = 4/3x + 2.
A six-sided number cube is rolled 900 times.
How many times is it expected that a number greater than 4 will be rolled?
Answer: Rolling a die and obtaining a number follows a binomial distribution.
Expected value of binomial distribution is
E[X]=np
where n is number of toss and p is probability of obtaining the number.
Therefore here the expected value of obtaining a number 4 is:
E[X]=900∗16=150
Step-by-step explanation:
It is expected that a number greater than 4 will be rolled 300 times
The sample space of a die is:
S = {1,2,3,4,5,6}
The probability of obtaining a number greater than 4 is:
[tex]p = 2/6[/tex]
[tex]p = 1/3[/tex]
In 900 rolls, the expected number of number greater than 4 is:
[tex]E(x) = p *n[/tex]
This gives
[tex]E(x) = 1/3 *900[/tex]
[tex]E(x) =300[/tex]
Hence, it is expected that a number greater than 4 will be rolled 300 times

There are five candies in a bag. Three are chewy, and two are chocolate. You draw a candy, do not replace it, and then draw another. What is the probability of choosing two chocolate candies?
P(Chocolate) for first draw = 2/5
P(Chocolate) for second draw = 1/4
Prob. of choosing two chocolate candies = 2/5 * 1/4 = 1/10
Probability of choosing two chocolates candies without replacement is equals to (1/ 10).
What is probability?
" Probability is defined as the mathematical expression which represents the ratio of number of favourable outcomes to the total number of outcomes for a given event."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Total number of candies = 5
Number of chocolates = 2
As per the condition of without replacement we have,
Probability of drawing a first chocolate = 2 / 5 ___( 1 )
Probability of second chocolate without replacing first one = 1/ 4 __( 2)
From ( 1 ) and (2) we get,
Probability of choosing 2 chocolates candies without replacement
= [tex]\frac{2}{5}[/tex] × [tex]\frac{1}{4}[/tex]
= (1 / 10)
Hence, probability of choosing two chocolates candies without replacement is equals to (1/ 10).

Answer:
Mikes repair shop $100 service charge plus $65 per hour Amys auto repair $40 service charge plus $80 per hour write an equation for each repair shop to represent the total cost of a car repair as a function of the number of hours worked let C = total cost to you let h = number of hours worked. Suppose you need to get the dent in your car repaired you see the ads above in the newspaper your father who knows a bit about cars said it would take no more than 3 hours for the repair person to fix your car how do you determine where you should take your car to get it repaired
-Mike Cost:: M(3) = 100 +65*3 = $295
-Amy Cost:: A(3) = 40 + 80*3 = $280
------------------------------------------------------------
-Mike charges 100 dollars service charge plus 65 dollars per hour.
-Amy charges 40 dollars service charge plus 80 dollars per hour.
-The cost to repair from mike is 100 + 65 * x.
-The cost to repair from amy is 40 + 80 * x.
------------------------------------------------------------
Let x = 3 and you get:
The cost to repair from mike is 100 + 65 * 3 = 295 dollars.
The cost to repaid from amy is 40 + 80 * 3 = 280 dollars.
As long as the time to repair is 3 hours or less, the cost to repair will be cheaper from Amy.

The company that fixing the car will be cheapest is; Amy's repir shop at a cost of $280
Simultaneous EquationsWe are given equation for total cost of repair shops as;
Cost of repair in Mike's shop is; y = 100 + 65x
Cost of repair in Amy's shop is; y = 40 + 80x
where;
x = number of hours for repair
y = total cost
Now, it takes 3 hours to repair your car. Thus;
Total cost of repair in Mike's shop is; y = 100 + 65(3) = $295
Total Cost of repair in Amy's shop is; y = 40 + 80(3) = $280
