Answer:

2x² - 14x + 24

Step-by-step explanation:

Use the FOIL method (First, Outside, Inside, Last).

First, multiply the first term of both parenthesis:

2x * x = 2x²

Next, multiply the outside terms of both parenthesis:

2x * -4 = -8x

Then, multiply the inside terms of both parenthesis:

-6 * x = -6x

Finally, multiply the last terms of both parenthesis:

-6 * -4 = 24

Combine like terms:

2x² - 8x - 6x + 24

2x² (-8x - 6x) + 24

2x² (-14x) + 24

2x² - 14x + 24 is your answer.

Answer:

2x^{2} -14x+24

Step-by-step explanation:

1. Distribute

(2x-6)(x-4)

2x(x-4)-6(x-4)

2. Distribute

2x(x-4)-6(x-4)      Distribute 2x(x-4)

2x^2-8x-6(x-4)

3. Distribute

2x^2-8x-6(x-4)       Distribute -6(x-4)

2x^2-8x-6x+24

4. Combine like terms

2x^2-8x-6x+24        Combine the like terms

2x^2-14x+24

Last week Lisa had gross earning of $441.30. Cathy receives a base salary of $375 and a commision on sales exceeding her quota o
vova2212 [387]

Answer:

4.25%

Step-by-step explanation:

<u>Step 1: Calculate the commission paid</u>

<em>Commission = Gross earning - base salary</em>

<em>Commission = 441.3 - 375</em>

Commission = 66.3

<u>Step 2: Calculate the commission sales</u>

<em>Commission sales = Total sales - quota sales</em>

<em>Commission sales = 6560 - 5000</em>

Commission sales = 1560

<u>Step 3: Calculate the rate of commission</u>

<em>x% of 1560 = 66.3</em>

<em>x% * 1560 = 66.3</em>

<em>x% = 0.0425</em>

x = 4.25%

Therefore, the rate of commission was 4.25%.

How many solutions does these equations have? One, infinite or no solutions?
s2008m [1.1K]

Answer:

  • 1. 7(y + 3) = 5y+8: <u>one solution</u>

  • 2. 10 + 6x= 2(5+3x): <u>infinite solutions</u>

  • 3. 3x + 5 - x=2x + 7: <u>no solutions</u>

  • 4. 4x - 4 = 2x + 8: <u>one solution.</u>

Explanation:

<u>1. 7(y+3)=5y+8</u>

<u></u>

a)  Distributive property of multiplication over addtion:

  • 7y + 21 = 5y + 8

b) Subtraction property of equalities:

  • 7y - 5y = 8 - 21

c) Combine like terms:

  • 2y = - 13

d) Division property of division:

  • y = - 13/2

e) Conclusion: the equation has one solution.

<u>2. 10 + 6x = 2(5+3x)</u>

a) Distributive property of multiplication over addition:

  • 10 + 6x = 10 + 6x

b) Subtraction property of equality:

  • 6x - 6x = 10 - 10

c) Simplify (combine like terms)

  • 0 = 0

That is an identity, i.e. that is always true, no matter the value of x.

d) Conclusion: the equation has infinite solutions.

<u>3. 3x + 5 - x = 2x + 7</u>

a) Combine like terms:

  • 2x + 5 = 2x + 7

b) Subtraction property of equalities:

  • 2x - 2x = 7 - 5

c) Combine like terms (simplify)

  • 0 = 2

That is always false, no matter the values of x.

d) Conclusion: the equation does not have any solutions.

<u>4. 4x - 4 = 2x + 8</u>

<u></u>

a) Subtraction property of equality

  • 4x - 2x - 4 = 2x - 2x + 8

b) Combine like terms

  • 2x - 4 = 8

c) Addtiion property of equalities:

  • 2x = 8 + 4

d) Combine like terms (simplify)

  • 2x = 12

e) Division property of equalities:

  • x = 6

f) Conclusion: the equation has one solution

The candy produced by a company has a sugar level that is normally distributed with a mean of 16.1 grams and a standard deviatio
artcher [175]

The correction option is B, It is out of control as one of these data points is more than 3 standard deviations from the mean.

<h3>What is Normal Distribution?</h3>

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.

Given that the candy produced by a company has a sugar level that is normally distributed with a mean of 16.1 grams and a standard deviation of 0.9 grams. Therefore, the maximum and the minimum weight of the candy can be,

Maximum weight = Mean + 3(Standard deviation)

                             = μ + 3σ

                             = 16.1 + 3(0.9)

                             = 16.1 + 2.7

                             = 18.8

Minimum weight = Mean - 3(Standard deviation)

                            = μ - 3σ

                            = 16.1 - 3(0.9)

                            = 16.1 - 2.7

                            = 13.4

Since one of the reading point, 19.4 is more than 3 standard deviations from the mean, therefore, it can be concluded that the process is out of control.

Hence, It is out of control as one of these data points is more than 3 standard deviations from the mean.
