Answer:

1 the line hits the y line at 1

Answer:

[tex]y = \frac{2}{3}x + \frac{7}{3}[/tex]

Step-by-step explanation:

Given

Line A:

[tex]y = -\frac{2}{3}x - 4[/tex]

Line B:

[tex](-2,1)[/tex]

Required

Determine the equation of Line B

First, we need to determine the slope of A using

[tex]y =mx + b[/tex]

Where:

[tex]m = slope[/tex]

By comparison:

[tex]y = -\frac{2}{3}x - 4[/tex]

[tex]m = -\frac{2}{3}[/tex]

Since A and B are perpendicular:

The slope of B (m2) is:

[tex]m_2 = \frac{-1}{m}[/tex]

[tex]m_2 = -1/\frac{-2}{3}[/tex]

[tex]m_2 = -1 * \frac{-3}{2}[/tex]

[tex]m_2 = \frac{3}{2}[/tex]

The equation of B is calculated as thus:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex](x_1,y_1) = (-2,1)[/tex]

[tex]m = \frac{2}{3}[/tex]

So, the equation becomes

[tex]y - 1 = \frac{2}{3}(x - (-2))[/tex]

[tex]y - 1 = \frac{2}{3}(x + 2)[/tex]

Open bracket

[tex]y - 1 = \frac{2}{3}x + \frac{4}{3}[/tex]

Make y the subject

[tex]y = \frac{2}{3}x + \frac{4}{3} + 1[/tex]

[tex]y = \frac{2}{3}x + \frac{4 + 3}{3}[/tex]

[tex]y = \frac{2}{3}x + \frac{7}{3}[/tex]

Answer:

47.6 cm

Step-by-step explanation:

Since the triangle is equilateral then the 2 inclined sides = 7.2 cm

Perimeter is then the sum of the 5 sides

P = 13 + 7.2 + 13 + 7.2 + 7.2 = 47.6 cm

A stem of 2 would have 3 leaves.

The correct answer is option (B) 3.

"It is a special table where each data value is split into a 'stem' (the first digit) and a 'leaf'( the last digit)."

For given data,

17, 22, 53, 74, 42, 26, 93, 15, 67, 29, 50

A stem-and-leaf representation would be:

Stem              Leaf/leaves

1                       7, 5

2                      2, 6, 9

4                      2

5                      3, 0

6                      7

7                      4

9                      3

From above plot, we can observe that a stem of 2 would have three leaves.

Therefore, option (B) is the correct answer.

Step-by-step explanation:

Answer:

[tex]Candy = \$188[/tex]

Step-by-step explanation:

[tex]Recycling = \$12[/tex] ---- earnings

[tex]Each = \$100[/tex] --- individual earnings

[tex]Individuals = 2[/tex] ---- Simon & Iris

Required

Determine earnings of selling candy

First, we need to determine the total earnings.

[tex]Total\ Earnings = Individuals * Individual\ Earnings[/tex]

[tex]Total\ Earnings = 2 * \$100[/tex]

[tex]Total\ Earnings = \$200[/tex]

Since the total earnings is from recycling and candy, we have:

[tex]Candy + Recycling = Total\ Earnings[/tex]

[tex]Candy + \$12= \$200[/tex]

[tex]Candy = \$200 - \$12[/tex]

[tex]Candy = \$188[/tex]

Answer:

Step-by-step explanation:

the objective is to maximize profit

let x be corn and y be oat

let us begging by formulating the linear program for the problem

The objective function is

  111x+47y=P

The constraints are

1. capital

 36x+18y=2100------------1

2. labor

6x(8)+2y(8)=2400

48x+16y=2400-------------2

solving 1 and 2 we apply substitution method

36x+18y=2100------1

36x=2100-18y

x=(2100-18y)/36

put x=(2100-18y)/36 in 2 we have

48(2100-18y)/36+16y=2400

(100800-864y)/36+16y=2400

2800-24y+16y=2400

-8y=2400-2800

-8y=-400

8y=400

y=400/8

y=50

to find x put y=50 in 36x+18y=2100------------1

36x+18(50)=2100------------1

36x+900=2100

36x=2100-900

36x=1200

x=1200/36

x=33.33

profit is

111x+47y=P

111(33.33)+47(50)=P

3699.63+2350=P

P=6049.63

Bachelor's degree salary = $53000

Master's degree salary = $66000

Step-by-step explanation:

Given that :

Let Salary of bachelor's degree holder = x

Salary of Master's degree holder = 2x - 40000

Master's salary + bachelor's salary = $119,000

Hence,

Master's salary + bachelor's salary = 119,000

2x - 40000 + x = 119,000

3x = 119000 + 40000

3x = 159000

x = 159000 / 3

x = $53,000

Bachelor's degree salary = $53,000

Master's degree salary ; 2x - 40000 ; 2(53000) - 40000 = $106,000 - $40,000 = $66000

Answer:

The probability is  [tex]P(\= X  > 103.7  )  =   0.9862 [/tex]

Step-by-step explanation:

From the question we are told that

  The population mean is  [tex]\mu =  106 \  gallons[/tex]

   The population standard deviation is  [tex]\sigma  =  6 \ gallons[/tex]

    The sample size is  [tex]n  =  33[/tex]

Generally the standard deviation of sample mean is mathematically represented as  

        [tex]\sigma_{x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>      [tex]\sigma_{x} = \frac{6}{\sqrt{33} }[/tex]

=>      [tex]\sigma_{x} = 1.044[/tex]

Generally the probability that the sample mean would be greater than 103.7 gallons is mathematically represented as

        [tex]P(\= X  > 103.7  )  =  P(\frac{X - \mu }{\sigma_{x}} > \frac{103.7  -  106}{1.044 }  )[/tex]

Generally  [tex]\frac{X - \mu }{\sigma_{x}}  =  Z (The \  standardized \  value \  of  \= X )[/tex]

So

[tex]P(\= X  > 103.7  )  =  P(Z > -2.203 )[/tex]

From the z table  the probability of (Z > -2.203 ) is  

     [tex]P(Z > -2.203 ) = 0.9862[/tex]

So

    [tex]P(\= X  > 103.7  )  =   0.9862 [/tex]

Step-by-step explanation:

Answer:

10%

Step-by-step explanation:

(a) What percentage of meals had less than 10 grams of fat?

(b) Round your answer to the nearest tenth of a percent.

To find the percentage of meals with less than 10 grams of fat, count the number of meals with less than 10 grams of fat and divide by the total number of meals; multiply this figure by a hundred.

(A) Total number of meals = 550

Number of meals having less than 10 grams of fat = 77

Percentage of meals having less than 10 grams of fat = 77/550 × 100

= 0.14 × 100 = 14%

(B) Rounding the answer to the nearest tenth of a percent means approximating it to the nearest multiple of 10 that is not more than 100 (where 100 here represents a full cent or 'percent').

The multiples of 10 that are close to 14 are 10 and 20. The closest being 10, your answer becomes 10%

Answer:

f(x) = (x + 5)(x - 1)

Step-by-step explanation:

f(x) = (x + 5)(x - 1) has the roots of -5 and 1, when you set each factor equal to zero.

x + 5 = 0

x = -5

So, -5 is a root of the function.

x - 1 = 0

x = 1

So, 1 is the other root of the function.

f(x) = (x + 5)(x - 1) is the polynomial function with the roots of -5 and 1

Step-by-step explanation:

Hey there!

The given points are; P(3,-7) and Q(-7,1)

Note: Use midpoint formula.

[tex]midpoint(x,y) = (\frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]

Put all values.

[tex](x,y) =( \frac{3 - 7}{2} , \frac{ - 7 + 1}{2} )[/tex]

Simplify it.

[tex](x,y) = (-2 , - 3[/tex])

Therefore, midpoint is (-2 ,-3).

Step-by-step explanation:

Answer:

(a) 36 points

(b) Pr(rolling a double number) ≅ 0.167

(c) Pr(a sum of 6 is rolled) ≅ 0.139

(d) Pr(a sum of 11 is rolled)  ≅ 0.056

(e) No.

Step-by-step explanation:

Sample space = {1,1  1,2  1,3  1,4  1,5  1,6  2,1  2,2  2,3  2,4  2,5  2,6  3,1  3,2  3,3  3,4  3,5  3,6  4,1   4,2  4,3  4,4  4,5  4,6  5,1  5,2  5,3  5,4  5,5  5,6  6,1  6,2  6,3  6,4  6,5  6,6}

(a) The number of points in the sample space is 36.

(b) Pr(rolling a double number) = [tex]\frac{6}{36}[/tex]

                                                   = [tex]\frac{1}{6}[/tex]  ≅ 0.167

(c) Pr(a sum of 6 is rolled) = [tex]\frac{5}{36}[/tex] ≅ 0.139

(d) Pr(a sum of 11 is rolled) = [tex]\frac{2}{36}[/tex]

                                           = [tex]\frac{1}{18}[/tex] ≅ 0.056

(e) No. It is more likely to roll a sum of 6 than that a sum of 11.
