Answer: 3/6 or 1/2

Step-by-step explanation:

In a 6-sided die, there are 3 odd numbers 1,3 and 5. So. P(odd) is 3/6 or 1/2.

All real values of a such that the given matrix is not invertible is -3.

To determine if a matrix is invertible, we can look at its determinant. A matrix is invertible if and only if its determinant is non-zero. Therefore, we need to find the values of a that make the determinant of matrix A equal to zero.

The determinant of matrix A is given by:

|A| = 0 1 a a 1 3 0 a 1 a

= 0(a(1)(1) - a(3)(1) + 1(0)) - 1(1(a)(1) - a(3)(0) + 1(0)) + a(1(3) - 1(0) + 0(a))

= -a + 3a + 3 - a

= a + 3

Therefore, the matrix A is not invertible when a = -3.

So the real value of a for which the matrix A is not invertible is -3.

Joe needs to transfer 28 quarts of oil into gallons containers joe calculated that he needs 112 containers but he made a mistake in his calculations identify and correct his error

Joe's error:

28 quarts × 4 quarts/ 1 gallon

= 28 quarts/1 × 4 quarts/ 1 gallon

= (28 × 4)/ ( 1 × 1) = 112 gallons

Answer:

7 gallons is the correct answer

Joe needs to transfer 28 quarts of oil into 7 gallons

Step-by-step explanation:

Joe's error:

28 quarts × 4 quarts/ 1 gallon

= 28 quarts/1 × 4 quarts/ 1 gallon

= (28 × 4)/ ( 1 × 1) = 112 gallons

Correcting Joe's error, we have:

4 quarts = 1 gallon

28 quarts = x

Cross Multiply

4 quarts × x = 28 quarts × 1 gallon

x = 28 quarts × 1 gallon/ 4 quarts

x = 7 gallons

= 28 quarts/x gallons × 1 gallon/4 quarts

= (28 × x)/ ( 1 /4) = 7 gallons

Therefore, Joe needs to transfer 28 quarts of oil into 7 gallons

The future value of depositing $1,000 every year for 20 years, with payments made at the beginning of each period, at an interest rate of 7% compounded yearly, is approximately $43,865.18.

To calculate the future value of a series of deposits, we can use the formula for the future value of an ordinary annuity:

FV = P * [(1 + r)^n - 1] / r

Where:

FV is the future value

P is the periodic payment

r is the interest rate per period

n is the number of periods

In this case, the periodic payment is $1,000, the interest rate is 7% (or 0.07), and the number of periods is 20.

Plugging these values into the formula, we get:

FV = 1000 * [(1 + 0.07)^20 - 1] / 0.07

  = 1000 * [1.07^20 - 1] / 0.07

  ≈ 1000 * [2.6532976 - 1] / 0.07

  ≈ 1000 * 1.6532976 / 0.07

  ≈ 43,865.18

Therefore, the future value of this series after 20 years would be approximately $43,865.18.

The amount that Ayaan will have in his tax-free savings account after 6 months of depositing $746 at 2.15% interest is $754.02.

The future value refers to the present value plus the interest.

The future value for this savings account can be computed using the simple interest system since there is no compounding of interest.

The initial deposit (present value) = $746

Interest rate = 2.15%

Answer:

The expression 75ℎ represents the total charge for Elegance Home Architects.

If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.

If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.

Step-by-step explanation:

Given the following :

Rock the house digital designs :

Initial consultation charge = $500

Additional hour of work for house plan = $50 /hr

Elegant Home Architect:

Charge = $75 / hr

h = number of hours fro which Johnson's family hires the design firm

Total amount charged by Elegant home Architect = 75 × h = 75h

Total amount charged by Rock the house digital design = (500 + 50h)

If h = 15 hours :

Total amount charged by Elegant home Architect = 75 × 15 = $1,125

Total amount charged by Rock the house digital design = (500 + 50(15)) = 500 + 750 = $1,250

Hence, Elegant home Architect is cheaper.

If h = 40 hours :

Total amount charged by Elegant home Architect = 75 × 40 = $3,000

Total amount charged by Rock the house digital design = (500 + 50(40)) = 500 + 2000 = $2,500

Hence, Rock the house digital design is cheaper.

The value of x that makes 25x^2 + 70x + c a perfect square trinomial is c = 1225.

To make the quadratic expression 25x^2 + 70x + c a perfect square trinomial, we need to determine the value of c.

A perfect square trinomial can be written in the form (ax + b)^2, where a is the coefficient of the x^2 term and b is half the coefficient of the x term.

In this case, a = 25, so b = (1/2)(70) = 35.

Expanding (ax + b)^2, we have:

(25x + 35)^2 = 25x^2 + 2(25)(35)x + 35^2

= 25x^2 + 70x + 1225.

Comparing this with the given quadratic expression 25x^2 + 70x + c, we can see that c = 1225.

Explanation:

The -1 and -7 of x-1 and x-7 respectively multiply to (-1)*(-7) = 7

Let m be some unknown value such that 7m = -21. The solution is m = -3

This means (-1)*(-7)*(-3) = -21

Therefore the factorization is

\(\text{x}^3-11\text{x}^2+31\text{x}-21 = (\text{x}-1)(\text{x}-7)(\text{x}-3)\)

You can confirm this by expanding out the right hand side using the distributive rule. You should arrive at the original cubic after everything is simplified.

Another approach:

(x-1) and (x-7) are the two dimensions given to us.

They multiply to \(\text{x}^2-8\text{x}+7\) using either the box method, distributive rule, or FOIL rule. Feel free to pick your favorite method.

Then the task from here is to compute \(\frac{\text{x}^3-11\text{x}^2+31\text{x}-21}{\text{x}^2-8\text{x}+7}\) using polynomial long division. Unfortunately synthetic division will not work because the denominator isn't linear.

In order to evaluate a function, replace the input variable (the number or expression given) (place holder, x). Replace the x by the number or word.

Step-by-step explanation:

price per house : $250,000

number of houses: 9

To find how much he will earn (y) we have to multiply the price per house by the number of houses (x).

y = 250,000 x

Where x is the independent variable (number of houses) and y is the dependent variable (earnings)

Replacing x by the number of houses:

y = 250,000 ( 9) = $2,250,000

If boat is heading towards a lighthouse, whose beacon-light is 142 feet above the water, the distance from point A to point B is approximately 226.6 feet.

To find the distance from point A to point B, we can use the tangent function. Let x be the distance between point A and the lighthouse, and let y be the distance between point B and the lighthouse. We can then set up two equations based on the angles of elevation:

tan(13°) = 142/x

tan(20°) = 142/y

Solving for x and y, we get:

x = 142/tan(13°) ≈ 627.8 feet

y = 142/tan(20°) ≈ 401.2 feet

The distance between point A and point B is the difference between x and y:

x - y ≈ 226.6 feet

From the question, the given parameters are:

The above parameters illustrate an exponential function

An exponential function is represented as

A(n) = A * (r)ⁿ⁻¹

Where

A represents the initial value

It is full on the 15th day

So, we have

1 = A *(2)¹⁵⁻¹

Evaluate

1 = A *(2)¹⁴

Divide by (2)¹⁴

A = (2)⁻¹⁴

Substitute A = (2)⁻¹⁴ in A(n) = A * (r)ⁿ⁻¹

A(n) = (2)⁻¹⁴ * (2)ⁿ⁻¹

When it is one-quarter full, we have

1/4 = (2)⁻¹⁴ * (2)ⁿ⁻¹

Multiply by (2)¹⁴

(2)¹² = (2)ⁿ⁻¹

By comparison, we have

n - 1 = 12

Add 1 to both sides

n = 13

The greatest common factor of the given expression 4x⁴ - 16x³ + 8x² + 12x will be 4x.

The Highest Common Factor (HCF) of two numbers is the highest possible number that is divisible by both numbers.

In other words, the highest common factor is the common factor between the two numbers but it should be the highest among all common factors.

For example in 6 and 12 6 is the highest common factor.

The Cartesian product is a mathematical operation that takes two sets and produces a set of all possible ordered pairs of elements from both sets.

In other words, if A and B are two sets, their Cartesian product (written as A × B) is the set of all possible ordered pairs (a, b) where a is an element of A and b is an element of B.

For example, if A = {1, 2} and B = {3, 4}, then A × B = {(1, 3), (1, 4), (2, 3), (2, 4)}.
