Answer:
13/30
Step-by-step explanation:
y= 5-3x
y= -3x+4
solution or no solution
Answer:
no solution
Step-by-step explanation:
y = 5 - 3x → (1)
y = - 3x + 4 → (2)
substitute y = - 3x + 4 into (1)
- 3x + 4 = 5 - 3x ( subtract 4 from both sides )
- 3x = 1 - 3x ( add 3x to both sides )
0 = 1 ← not possible

Answer:
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)
randy read a book in the afternoon. He looked at his watch when he started and finishing reading. How long did randy read
The length of the time that randy read is 45 minutes.
What is time?Time is known to be an element that is often measured or that is measurable.
From the image attached, Randy started reading at 4:10 and Randy finished reading at 4:55.
We therefore need to subtract:
4:55 - 4:10 = 45 minutes
So, Randy is said to read for 45 minutes.

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.
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

When you have a 90-degree angle in a triangle, what happens to the law of cosines? What formula does it "turn in to"?
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.

two six sided dice are rolled and the two dice equals 7. what is the probability that one die is a 3
Let us solve the problem step by step.
here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.
Now, it is time to calculate the probability.
The required probability is,
p = (No. of cases favorable for the event)/(Total no. of cases)
=6/36 = 1/6
Therefore your answer is 1/6.If two six-sided dice are rolled and the two dice are equal. The probability that one die is a 3 will be 6.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that, two six-sided dice are rolled and the two dice equal 7.
If two dice are rolled. The total no. of possible outcomes will be,
= 6²
=36
The total outcomes are,
(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
If the desired outcome is their sum which is 7. All the possible cases are 6,
(1,6), (2,5), (3,4), (4,3), (5,2), (6,1)
The required probability is,
p(sum=7) = (No. of cases favorable for the event)/(Total no. of cases)
p(sum=7)=6/36
p(sum=7)= 1/6
Thus, if two six-sided dice are rolled and the two dice are equal. The probability that one die is a 3 will be 6.
