The sum of digits in 343 is 10, an even number, while in 124 it is 7, an odd number. There are 450 three-digit numbers with an even sum of digits.


To determine the number of 3-digit numbers from 100 to 999 (inclusive) where the sum of the digits is even, we need to consider the possible combinations of digits.

There are 9 choices for the hundreds digit (1 to 9), 10 choices for the tens digit (0 to 9), and 10 choices for the units digit (0 to 9).

If the hundreds digit is fixed, there are two possibilities for the sum of the tens and units digits: even or odd.

For odd sums, half of the options will be even and the other half will be odd.

Therefore, half of the total combinations will have an even sum of digits.

Hence, there are 450 three-digit numbers from 100 to 999 (inclusive) with an even sum of digits.

Option 2 is true.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

House worked = 2, 4 , 5, 8

Amount paid = 30.40 , 60.80 , 76 , 121.60

Now,

Find the correct expression as;

Take two condition for find the expression,

x₁ = 2 and y₁ = 30.40

x₂ = 4 and y₂ = 60.80

So, The equation of line for the given condition is defined as;

y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Hence, m = (60.80 - 30.40) / (4 - 2)

m = 30.40 / 2

m = 15.20

Thus, The equation of line for the given condition is defined as;

y - 30.40 = 15.20 (x - 2)

y - 30.40 = 15.20x - 30.40

y = 15.20x

Therefore,

The correct expression for the given condition will be;

⇒ y = 15.2x

To simplify the ratio 85:34, we need to find the greatest common divisor (GCD) of the two numbers and divide both terms of the ratio by it. In this case, the GCD of 85 and 34 is 17, so we divide both terms by 17.

Dividing 85 by 17 gives us 5, and dividing 34 by 17 gives us 2. Therefore, the simplified form of the ratio 85:34 is 5:2. Simplifying a ratio to its simplest form ensures that it represents the smallest whole number ratio between the two quantities being compared. In this case, the simplified ratio 5:2 tells us that for every 5 units of one quantity, there are 2 units of the other quantity. This simplified form is easier to work with and interpret, providing a clear understanding of the relationship between the two values.

To compute 101^(4,800,000,023) mod 35 using the Chinese Remainder Theorem, we need to first decompose 35 into its prime factors: 35 = 5 × 7.

Next, we need to compute 101^(4,800,000,023) mod 5 and 101^(4,800,000,023) mod 7 separately.

To compute 101^(4,800,000,023) mod 5, we can use Fermat's Little Theorem, which states that if p is a prime number and a is a positive integer not divisible by p, then a^(p-1) ≡ 1 mod p. Since 5 is prime and 101 is not divisible by 5, we have 101^(4) ≡ 1 mod 5. Therefore, 101^(4,800,000,023) ≡ 101^(4 × 1,200,000,005 + 3) ≡ (101^4)^1,200,000,005 × 101^3 ≡ 1^1,200,000,005 × 101^3 ≡ 1 × 101^3 ≡ 1 mod 5.

To compute 101^(4,800,000,023) mod 7, we can use Euler's Totient Theorem, which states that if a and m are coprime positive integers, then a^φ(m) ≡ 1 mod m, where φ(m) is Euler's totient function. Since 7 is prime and φ(7) = 6, we have 101^6 ≡ 1 mod 7. Therefore, 101^(4,800,000,023) ≡ 101^(6 × 800,000,003 + 5) ≡ (101^6)^800,000,003 × 101^5 ≡ 1^800,000,003 × 101^5 ≡ 101^5 ≡ 4 mod 7.

Now we can use the Chinese Remainder Theorem to combine the results. Let x ≡ 1 mod 5 and x ≡ 4 mod 7. Then we can write x = 5k + 1 for some integer k. Substituting this into the second congruence, we get 5k + 1 ≡ 4 mod 7, or equivalently, k ≡ 6 mod 7. Therefore, x = 5k + 1 ≡ 5(6) + 1 ≡ 31 mod 35.

Hence, 101^(4,800,000,023) mod 35 = x = 31.

We need to find the inverse of the function f(x) = 1/x. Therefore, h'(3) = -1/\(3^2\) = -1/9. So, h'(3) = -1/9.

In the equation expressing the function, swap out f(x) with y. Swap out x and y. To put it another way, swap out every x for a y and vice versa.

An inverse in mathematics is a function that is used to another function.

Calculate y using a solution.

To find the inverse, we switch the x and y variables and solve for y:

x = 1/y

y = 1/x

So the inverse function of f(x) = 1/x is h(x) = 1/x.

Now, we need to find h'(3), the derivative of h(x) at x = 3.

h(x) = 1/x, so using the power rule of differentiation, we get:

h'(x) = -1/\(x^2\)

Therefore, h'(3) = -\(1/3^2\) = -1/9.

So, h'(3) = -1/9.

The value of b that makes the expression 9(a+5) and 9(b+a) equivalent is 5.

To make the expression 9(a+5) and 9(b+a) equivalent, we need to find the value of b that makes them equal for all values of a.

We can start by expanding expressions using distributive property of multiplication:

9(a+5) = 9a + 45

9(b+a) = 9b + 9a

Two expressions will be equal if 9a + 45 = 9b + 9a for all values of a.

Simplify this equation by subtracting 9a from LHS and RHS:

45 = 9b

Finally, divide by 9 by b:

b = 5

To make the expressions equivalent, we need to find the value of b that makes 9(a+5) equal to 9(b+a) for all values of a. We can do this by expanding both expressions and equating them, and then solving for b. The value of b that we get is 5, which means that we can rewrite 9(a+5) as 9(5+a) to make it equivalent to 9(b+a).

The area under the standard normal curve to the left of z = 1.72 is 0.0427. To find the area to the right of z = 1.72, we can subtract the area to the left from 1.

Subtracting 0.0427 from 1 gives us an area of 0.9573. Therefore, the area under the standard normal curve to the right of z = 1.72 is approximately 0.9573.In the standard normal distribution, the total area under the curve is equal to 1. Since the area to the left of z = 1.72 is given as 0.0427, we can find the area to the right by subtracting this value from 1. This is because the total area under the curve is equal to 1, and the sum of the areas to the left and right of any given z-value is always equal to 1.

By subtracting 0.0427 from 1, we find that the area under the standard normal curve to the right of z = 1.72 is approximately 0.9573. This represents the proportion of values that fall to the right of z = 1.72 in a standard normal distribution.
