Nadia says the hypotenuse of this right triangle has a length of 73 because the Pythagorean theorem states that (28 + 45) squared = 73 squared.
3 squares are positioned to form a right triangle. The small square is labeled 28, medium square is 45, and large square is not labeled.
Which best describes Nadia’s solution?
She is correct because she applied the Pythagorean theorem properly and her arithmetic is accurate.
She is incorrect because she should have used 45 as the length of the hypotenuse.
She is incorrect because she should have squared each leg length and then found the sum.
She is correct because the hypotenuse is the longest side of the triangle.

What is the Pythagorean theorem?A right angled triangle is a three-sided polygon. The three sides are the length, base and the hypotenuse. The hypotenuse is the longest side of the triangle. The sum of angles in a right angled triangle is 180 degree.
The Pythagorean theorem can be used to determine the length of the hypotenuse given the lengths of the other sides of the triangle. According to this theorem, the sum of the square of the two sides is equal to the length of the hypotenuse.
The Pythagoras theorem: a² + b² = c²
where:
a = lengthb = basec = hypotenuse28² + 45²
= 784 + 2025 = 2809
Hypotenuse = √2809= 53

If we want the two ratios to be equivalent, then we need to use x = 15 and y = 33.
How to find the values of x and y such that the two ratios are equivalent?
Let's say that we have a simple ratio between two amounts, it is A:B
If we multiply both of these amounts by the same scalar, k, we will get:
k*A and k*B
And the ratio between the new amounts k*A: k*B is equivalent to the first ratio, A:B
So we will use this to solve the problem, here we have two ratios:
5:2:11 = x:6:y
Note that in the first ratio the first value is 2, and in the second case it is 6 so let's find the value of k such that:
2*k = 6
k = 6/2 = 3
Then if we multiply the correspondent values in the first ratio by 3, we will get:
x = 5*3 = 15
y = 11*3 = 33
Then we can see that the ratios:
5:2:11 and 15:6:33 are equivalent.

Tristan expects to work an average of 12 hours a week during next semester. Assuming he makes $9.50 an hour and works the entire 17 week semester, what is his forecast for income next year?
Answers
Tristan's forecast for income next year is $3,876.
How is the forecast income determined?The forecast income can be determined using the mathematical operation of multiplication.
First, the total number of hours worked next year is determined as 204. This is a product of 17 weeks and a 12-hour week.
Lastly, the above product multiplies the hourly pay rate at $9.50 by two semesters, to determine the expected income for next year.
The average hours of work by Tristan per week = 12 hours
Hourly pay rate = $9.50
The total number of weeks to work = 17 weeks
The total number of hours to be worked = 204 hours (17 x 12)
Expected earnings for each semester = $1,938 ($9.50 x 204)
Expected earnings for two semester = $3,876 ($1,938 x 2)
Thus, Tristan should expect to earn $3,876 for next year.

In this question, we have been given a statement 'My bank raised its interest rate on savings accounts from 2% to 2.8%, which was a 40% increase.'
We need to check whether given statement is true or false.
The bank raised its interest rate on savings accounts from 2% to 2.8%
We find the percent increase.
Here the absolute increase is: |2.8 - 2| = 0.8
The relative increase is: absolute increase / original value
= 0.8 / 2
= 0.4
The percent increase is: relative increase × 100
= 0.4 × 100
= 40%
Therefore, given statement 'My bank raised its interest rate on savings accounts from 2% to 2.8%, which was a 40% increase.' is True.

The constant of proportionality is 190.
The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality.
Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality. The ratio of two proportional values at a constant value is known as the constant of proportionality. Two variables are said to be proportionately connected when either their ratio or product equals a constant. The proportionality constant's value is determined by the ratio of the two mentioned quantities. For this relationship, it is conceivable for there to be both direct and inverse variation.To find proportionality constant we will find difference of weights of the baby whale after 2 days and at birth.
5710 - 5520 = 190
Now we will find difference of weights of the whale after 14 days and at birth.
We will divide the difference by 14.
(8180-5520) ÷ 14 = 190
Weights are rising at a consistent rate of 190 pounds every day, as can be seen. As a result, 190 is our proportionality constant.

In order to determine the greatest students we need to calculate the greatest common divisor of the numbers.
To calculate the greatest common divisor, we need to find out the prime factors of each number.
Therefore, by the method of prime factorization.
Prime factors of 48 = 2 × 2 × 2 × 2 × 3
Prime factors of 64 = 2 × 2 × 2 × 2 × 2 × 2.

According to the given information the triangle is an right angled triangle with sides a,b, c where a and b are the two legs of the triangle and c is the hypotenuse the measurments of the side a and c are given 12 and 13 respectively . For finding the value of b we need to use pythagoras theorem that is (Hypotenuse)² = (base)² + (height)²
Here we are going to use the same theorem for finding the value of the side b
According to the question:
hypotenuse = c = 13 units
height = a = 12 units
base = b = ?
As per the theorem : hypotenuse ² = base ² + height²

Answers
Assuming an hypergeometric distribution, the probability that both are red is equal to 33.99%
In an hypergeometric distribution, these three (3) conditions listed below must hold:
There must be two (2) classes, in which one class is considered as failure (N - M) while the other is success (M). Also, N represents the total number of items in the two (2) classes.There must be n trial or n chosen items.The probability of success isn't fixed for each trial.In Mathematics, probability from an hypergeometric distribution can be calculated by using this formula:
[tex]p(X = x) = \frac{^MC_x \;^{N-M}C_{n-x}}{^NC_n}[/tex]
N = 12 + 31 = 43
n = 2
M = 12
N - M = 43 - 12 = 31
Substituting the parameters into the formula, we have;
