you are employed at a grain processing plant that sells cornmeal for $1.28 per pound. if a sack of cornmeal weighs 4 pounds 12 ounces, how much does it cost?

Answer:

1.2

Step-by-step explanation:

First make -1.5 equal to 0.

We'll have to add 1.5, right?

So 1.5 is in 2.7.

So now its 0 + ? = ?

2.7 - 1.5 = 1.2

So 0 + 1.2 = 1.2

Answer:

y = 500 * (2)^x is an exponential function

Step-by-step explanation:

An exponential function is of the form

y = a b^x  where a is the initial value and b is the growth/decay factor

y = 500 * (2)^x is an exponential function

The correct equation that represents an exponential function with an initial value of 500 is:

f(x) = 500(2)x

The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

We are given that the initial value of the exponential function is 500. The initial value refers to the value of the function when x is equal to zero. Therefore, the value of f(0) is 500.

Out of the four given options, only option (c) represents an exponential function with an initial value of 500, since f(0) is equal to 500 when x is equal to zero:

f(x) = 500(2)^x

Option (a) represents an exponential function with an initial value of 100 and a base of 5.

Option (b) represents a power function, not an exponential function.

Option (d) represents an exponential function with an initial value of 0 and a base of x^2, which can take any value including negative values, thus it doesn't satisfy the conditions of a valid exponential function.

The length of the third side of the triangular garden is 30 meters.

Let,

The length of the third side = x

The length of the first side = 28 meters

The length of the second side = 43 meters

The perimeter of the triangular garden = 101 meters

The perimeter is the sum of the measures of all the sides of a figure.

Perimeter = sum of the three sides of the triangle

Perimeter = 28+43+x

Substitute perimeter=101:

101 = 28+43+x

101 = 71+x (simplify)

30 = x (subtract 71 on both sides of the equation)

Therefore, the triangular garden will have a length of 30 meters if the perimeter is 101 meters.

The angles measures from least to greatest is:

m ∠J<m ∠K < m ∠I

An angle is a figure in Euclidean geometry made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are located in the plane where the rays are located. The meeting of two planes can also create an angle. These are referred to as dihedral angles. The angle formed by the rays lying perpendicular to the two intersecting curves at their point of intersection can likewise be used to establish an angle between two intersecting curves.

Angle can also be used to describe the size of an angle or of a rotation. This metric represents the proportion of a circular arc's length to radius.

From the diagram,

The largest side is JK

Since opposite side is longer, ∠I  is greatest

And since smallest side is smaller then ∠J is smallest

The variance of z is - 177.1788.

The discrete random variable X representing the number of errors per 100 lines of software code has the following probability distribution. X 2 3 4 5 6 P(X) 0.01 0.25 0.4 0.3 0.04

We can apply Theorem 4.2 to find the variance of X. Theorem 4.2: Let X be a discrete random variable with probability distribution p(x). If the mean of X is μ and the variance of X is σ², then μ = E(X) = ∑x p(x) and σ² = Var(X) = E(X²) - [E(X)]².

Now, we find the mean and variance of the discrete random variable z = 3X – 2.

The mean of z = 3X - 2 is E(z) = E(3X - 2) = 3E(X) - 2.

Hence, the mean is μz = 3(2)(0.01) + 3(3)(0.25) + 3(4)(0.4) + 3(5)(0.3) + 3(6)(0.04) - 2= 14.53.

The variance of z = 3X - 2 is Var(z) = Var(3X) = 9Var(X).

Hence, the variance of X is σz² = 9Var(X) = 9[E(X²) - [E(X)]²] = 9[(2²)(0.01) + (3²)(0.25) + (4²)(0.4) + (5²)(0.3) + (6²)(0.04) - 14.53²] = 34.0021 - 211.1809 = - 177.1788

Step-by-step explanation:

on the first step, where the student subtracted the two equations, when they subtracted 3y - y, they got 4y, but they were supposed to get 2y.

If they did it right it would look like this

 2x + 3y = 8

-(2x  +  y = 16)

0x + 2y = -8

y = -4

2x - 4 = 16

2x = 20

x = 10

Solution (10,-4)

You must find the error, I will correct their work.

This is a system of linear equations. To solve it, you can use the substitution method. First, you can solve the first equation for x and substitute it into the second equation:

2x + 3y = 8

2x = 8 - 3y

x = (8 - 3y) / 2

2((8 - 3y) / 2) + y = 16

8 - 3y + 2y = 16

5y = 8

y = 8 / 5

Then, you can substitute y into the first equation:

2x + 3(8 / 5) = 8

2x = 8 - 24 / 5

2x = 16 / 5

x = 16 / 10

Therefore, the solution to the system of linear equations is x = 16/10 and y = 8/5.

Henry opens a savings account with an annual interest rate of 4.5 percent. After a year, he gets $75,000 in payment. He made a deposit into the savings account of $72,831.68.

Here are the steps on how to calculate the amount Henry invested:

Convert the annual interest rate to a monthly rate.

\(\begin{equation}4.5\% \div 12 = 0.375\%\end{equation}\)

Calculate the number of years.

\(\begin{equation}\frac{18 \text{ months}}{12 \text{ months/year}} = 1.5 \text{ years}\end{equation}\)

Use the compound interest formula to calculate the amount Henry invested.

\(\begin{equation}FV = PV * (1 + r)^t\end{equation}\)

where:

FV is the future value ($75,000)

PV is the present value (unknown)

r is the interest rate (0.375%)

t is the number of years (1.5 years)

\(\begin{equation}\$75,000 = PV \cdot (1 + 0.00375)^{1.5}\end{equation}\)

\$75,000 = PV * 1.0297

\(\begin{equation}PV = \frac{\$75,000}{1.0297}\end{equation}\)

PV = \$72,831.68

Therefore, Henry invested \$72,831.68 in the savings account.

Compute the Gaussian density for the following cases. (a) x=0, m=0, s-1. Give the name of question5a (b) x-2, m=0, s-1. The value of the account on January 1, 2021, would be $2,331.57.

To calculate the value of the account on January 1, 2021, we need to consider the compounding interest for each year.

First, we calculate the value of the initial deposit after three years (12 quarters) using the formula for compound interest:

Principal = $1,000

Rate of interest per period = 8% / 4 = 2% per quarter

Number of periods = 12 quarters

Value after three years = Principal * (1 + Rate of interest per period)^(Number of periods)

                           = $1,000 * (1 + 0.02)^12

                           ≈ $1,166.41

Next, we calculate the value of the additional $1,000 deposit made on January 1, 2019, after two years (8 quarters):

Principal = $1,000

Rate of interest per period = 2% per quarter

Number of periods = 8 quarters

Value after two years = Principal * (1 + Rate of interest per period)^(Number of periods)

                         = $1,000 * (1 + 0.02)^8

                         ≈ $1,165.16

Finally, we add the two values to find the total value of the account on January 1, 2021:

Total value = Value after three years + Value after two years

                ≈ $1,166.41 + $1,165.16

                ≈ $2,331.57

Therefore, the value of the account on January 1, 2021, is approximately $2,331.57.

a) The explanatory variable in the study is the format of the stories presented to the four-year-olds: audio, illustrated, and animated. This variable is categorical because it involves distinct categories or formats.

b) The response variable in the study is the brain connectivity measured by the magnetic resonance imaging (MRI) machine. This variable is quantitative as it represents a numerical measurement of brain connectivity.

c) The study includes 27 four-year-olds as the observational units or individuals.

The study aimed to investigate the impact of different story formats on brain connectivity in four-year-olds. The explanatory variable, format, was categorized into three groups: audio, illustrated, and animated.

The response variable, brain connectivity, was measured using an MRI machine. The researchers found a "Goldilocks effect" in the brain connectivity, indicating that the audio format was associated with low brain connectivity, possibly due to the children straining to understand.

On the other hand, the animated format also resulted in low brain connectivity, suggesting that the animation did all the work for the children.

The highest brain connectivity, considered optimal, was observed with the illustrated format, which simulated the experience of reading a book to a child.

The study included 27 four-year-olds as the observational units, providing insights into the relationship between story format and brain connectivity in young children.
