Final answer:

Taylor's net proceeds from the stock transaction are $525, after accounting for the initial purchase cost and broker's commissions on both the buying and selling of the stock.

Explanation:

Taylor bought 200 shares of stock at $18.12 per share and paid a flat brokerage fee of $30. To find the initial cost, we multiply the number of shares by the purchase price and then add the fee:

200 shares × $18.12/share + $30 = $3,654

When Taylor sold his shares at $21 per share, his gross proceeds were:

200 shares × $21/share = $4,200

The broker commission of 0.5% on the selling price is calculated as:

$4,200 × 0.005 = $21

To find Taylor's net proceeds, we subtract both the initial cost and the selling commission from the gross proceeds:

$4,200 - $3,654 - $21 = $525

Therefore, Taylor's net proceeds from the stock transaction are $525.

let x = hours

6x + 14x = 40

20x=40

x = 40/20 = 2 hours

1 pm + 2 hours = 3 pm

eastbound trains is going 14 miles per hour, 14 mph x 2 hours = 28 miles

 Answer is A. 3 pm and 28 miles

The eastbound train has traveled 28 miles and they met at 3:00 pm

Speed is the ratio of total distance to total time taken. It is given by:

Speed = distance / time

Let both cargo trains meet each other at time t.

For the train traveling west:

6 = d₁ / t

d₁ = 6t

For the train traveling east:

14 = d₂ / t

d₂ = 14t

Since both trains are 40 miles apart, hence:

d₁ + d₂ = 40

6t + 14t = 40

20t = 40

t = 2 hours

t = 3:00 pm (1:00 pm + 2 hours)

Distance travel by east bound train = d₂ = 14t = 14(2) = 28 miles

The eastbound train has traveled 28 miles and they met at 3:00 pm

Answer:

[tex]\frac{4}{5}\frac{cup}{liter}.[/tex]

Step-by-step explanation:

The problem says that Angela uses 2/3 cup strawberries to make 5/6 liter of smoothies. Then, to find the unit rate in cups of strawberrry per liter, that is cup/liter we need to divide both fractions:

[tex]\frac{\frac{2}{3}cup}{\frac{5}{6}liter} = \frac{2*6}{3*5}\frac{cup}{liter} = \frac{12}{15}\frac{cup}{liter}= \frac{4}{5}\frac{cup}{liter}.[/tex]

Then, the unit rate in cups of strawberry per liter is [tex]\frac{4}{5}\frac{cup}{liter}.[/tex] That is, Angela uses 4/5 cups of strawberry to do 1 liter of smoothie.

Final answer:

To identify a basis for the row and column spaces of a matrix and determine its rank, one uses row reduction to reach REF or RREF. The non-zero rows of the RREF are the basis for the row space, the corresponding columns in the original matrix form the basis for the column space, and the rank is the number of these basis vectors. In statistics, the degrees of freedom for the Test of Independence is calculated as (number of columns - 1)(number of rows - 1).

Explanation:

To find a basis for the row space and column space of a matrix as well as the rank, you follow specific procedures. First, perform row reduction on the matrix to bring it to row echelon form (REF) or reduced row echelon form (RREF). The non-zero rows of the RREF correspond to a basis for the row space. The columns in the original matrix that correspond to the leading 1s in the RREF form a basis for the column space. The rank of the matrix is equal to the number of leading 1s in the RREF form, which is also the number of basis vectors for either the row space or column space since they have the same dimension.

The Test of Independence in statistics uses a contingency table to determine if two categorical variables are independent. The number of degrees of freedom for the test is given by the formula: (number of columns - 1)(number of rows - 1). This is critical when referencing the chi-squared distribution table to determine the p-value for the hypothesis test.

Step-by-step explanation:

The end behavior of the function f(x) = 2x³ – 26x – 24 can be described as:

As x → -∞, y →-∞ and as x→∞, y →∞.

An expression that consists of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

To determine the end behavior of the polynomial function f(x) = 2x³ – 26x – 24, we need to examine the degree of the polynomial and the sign of its leading coefficient.

The degree of the polynomial is 3, which means it is an odd-degree polynomial.

The sign of the leading coefficient is positive (+2). These two pieces of information tell us that the end behavior of the graph will be as follows:

As x becomes very large in the positive direction, the values of the function will also become very large in the positive direction.

As x becomes very large in the negative direction, the values of the function will become very large in the negative direction.

Therefore, as x → -∞, y →-∞ and as x→∞, y →∞.

there are 4 9's in a deck

 so first pick = 4/52 reduces to 1/13

second pick there would be 3 9's left and 51 cards so it would be 3/51 reduces to 1/17

probability of both happening = 1/13 * 1/17 = 1/221 (fraction form)

 if you need it in decimal it = 1/221 = 0.00452, rounded to 0.005

48/75

 both numbers are divisible by 3

 so it simplifies to 16/25

Answer: The answer is y = 500(1.04) x

Step-by-step explanation: The formula is y = P (1 + r) x

So, given that P which is the initial value 500(1+0.4) x

f(x)=500(1.04) x

Probabilities are used to determine the chances of an event

The value of P(a and b) is 0.21

The given parameters are:

P(a) = 0.62

P(b) = 0.47

P(a or b) = 0.88

P(a and b) is calculated using the following formula

P(a and b) = P(a) + P(b) - P(a or b)

So, we have:

P(a and b) = 0.62 + 0.47 - 0.88

P(a and b) = 0.21

Hence, the value of P(a and b) is 0.21

Final answer:

To find the remainder when dividing x^4-3x^2-9x+4 by x-3, substitute x=3 into the polynomial and calculate the expression.

Explanation:

To find the remainder when dividing x^4-3x^2-9x+4 by x-3, we can use the Remainder Theorem. According to the theorem, if we substitute the opposite of the divisor into the polynomial, the remainder will be the value we get.

So, substitute x = 3 into the polynomial:

3^4 - 3(3)^2 - 9(3) + 4

Calculating this expression, we find that the remainder is 142.

Step-by-step explanation:

We can use rule of three to answer this problem.

The data we have is the following:

fertilizer (ounces)        area(m^2)

            1/2                ⇒     5/8

              x                 ⇒       1

the x represents the unknown quantity of fertilizer that is used in one square meter.

Now we multiply the cross quantities and divide by the remaining value.

[tex]x=\frac{1}{2}*1[/tex] ÷ [tex]\frac{5}{8}[/tex]

[tex]x=\frac{1*8}{2*5} =\frac{8}{10} =\frac{4}{5}[/tex]

He will use 4/5 ounces of fertilizer per square meter.
