Joe takes part in math competitions. A particular contest consists of 25 multiple-choice questions, and each question has 5 possible answers. It awards 6 points for each correct answer, 1. 5 points for each answer left blank, and 0 points for incorrect answers. Joe is sure of 12 of his answers. He ruled out 2 choices before guessing on 4 of the other questions and randomly guessed on the 9 remaining problems. What is his expected score? 69. 2 75. 6 90. 8 97. 2.
Answers
The expected score that Joe can obtain provided the probability of the left-out questions being correct as per the given situation is 90.8.
Points secured by Joe by answering correctly = 12*6 = 72
What is probability?Probability is the conversion of possibilities or occurrences in numbers.
Now, the probability of a correct guess in the questions in which Joe eliminated 2 choices = 1/3
So, the possible marks of Joe in those 4 questions = 1/3*4*6=8
Probability of correct guess in remaining 9 random guesses= 1/5
So, the possible marks that Joe can score in those 9 random guesses = 1/5*9*6 = 10.8
Therefore, the expected score of Joe = 72+8+10.8 = 90.8

A quadrilateral has vertices at (1,1), (4,2), (0,4), and (5,5). What is the perimeter of the quadrilateral?
Answers
Answer:
3√10 +√26 ≈ 14.6 units
Step-by-step explanation:
In order to find the perimeter of the figure, we need to determine the lengths of its sides. A plot of the points on a graph reveals that three sides are a length that is the hypotenuse of a right triangle with legs 3 units and 1 unit. Those lengths are ...
c² = a² +b²
c = √(3² +1²) = √10
The remaining longer leg is the hypotenuse of a right triangle with legs 5 units and 1 unit. Its length is ...
c = √(5² +1²) = √26
__
The perimeter of the figure is the sum of its side lengths. The sum of the lengths of the three short sides and the long side is ...
3√10 +√26 ≈ 14.59 . . . units
The perimeter of the quadrilateral is about 14.6 units.

c = 0.50(0.48)(1525)
Step-by-step explanation:
If 52% of the students are female, then
100% - 52% = 48% of the students are male
48% = 48/100 = 0.48
To find the number of students who are male:
⇒ total number of students x 0.48 = 0.48 x 1525
Half = 50% = 50/100 = 0.50
⇒ half of the male students = 0.50 x 0.48 x 1525
Solution: c = 0.50(0.48)(1525)

Where did Angie make an error? Justify your answer.
Step 1; because she should have multiplied the second equation by -1.
Step 2; because she should have eliminated the y-value.
Step 3; because she used substitution incorrectly.
Step 4; because the solution is (2,-26).
Answers
Angie made an error because she used substitution incorrectly in step 3.
System of equation7x + y =−12
7x + 4y = −6
subtract equation(i) from (ii) to eliminate x
Therefore,
3y = 6
y = 6 / 3
y = 2
Therefore,
7x + 2 = -12
subtract 2 from both sides of the equation
7x = -12 - 2
7x = - 14
x = - 14 / 7
x = -2
(-2, 2)
Therefore, Angie use substitution incorrectly in step 3.

When you have a 90-degree angle in a triangle, what happens to the law of cosines? What formula does it "turn in to"?
Answers
Answer:
Pythagorean Theorem
Step-by-step explanation:
a² + b² = c²
The sum of the square of the hypotenuse is equal to the sum of the squares of the sides of the right triangle.
When you have a 90-degree angle in a triangle, the Law of Cosines simplifies to the Pythagorean theorem: c² = a² + b².
When you have a 90-degree angle in a triangle, it means that the triangle is a right triangle.
In a right triangle, one of the angles is exactly 90 degrees, and the side opposite to this right angle is called the hypotenuse.
The Pythagorean theorem relates the lengths of the sides of a right triangle and is a special case of the Law of Cosines.
The Law of Cosines is given by:
c² = a² + b² - 2abcos(C)
Where:
c is the length of the side opposite angle C.
a and b are the lengths of the other two sides.
C is the angle opposite side c.
Now, when you have a right triangle and C is the right angle (90 degrees), the cosine of the right angle becomes zero.
This is because the cosine of 90 degrees is 0.
Therefore, the Law of Cosines simplifies to:
c² = a² + b² - 2abcos(90°)
c² = a² + b²
Hence, c² = a² + b² is the well-known formula for the Pythagorean theorem, which relates the squares of the lengths of the two shorter sides (legs) of a right triangle to the square of the length of the hypotenuse.
