Answer:

The answer you're looking for is .5

Step-by-step explanation:

Cause 20 is less than 21, and 25, 26, and 27 is larger than 24, and that's 4 numbers. There's 8 numbers in total, so your answer is 4/8. Divide that by 4, and you get 1/2. That's 50%, if you're thinking out of "1" then it would be ".5"

Answer: 0.5 or 50%

Numbers-Set {20, 21, 22, 23, 24, 25, 26, 27}

Total outcomes: 8

numbers greater than 24 are 25, 26, 27 - 3 numbers

number less than 21 is 20 - 1 number

Total favorable outcomes: 3 + 1 = 4

Probability = favorable outcomes/total outcomes = 4/8 = 0.5

The statement " only the estimate intercept is statistically significant at the 5% level is wrong" is wrong about the estimate.

A probit model is a type of regression in statistics where the dependant variable can only take two values.

We have:

The cash value of the computer system in 3 years will be $1632. The correct option is the third option $1632

From the question, we are to determine the cash value of the computer system in 3 years

From the given information,

The computer system cost $2,395 and it will depreciate at a rate of 12% a year

After the first year, the worth of the computer system will be

$2,395 - (12% of $2,395)

$2,395 - (0.12 × $2,395)

= $2,395 - $287.4

= $2107.6

After the second year, the worth of the computer system will be

$2107.6 - (12% of $2107.6)

$2107.6 - (0.12 × $2107.6)

= $2107.6 - $252.912

= $1854.688

After the third year, the worth of the computer system will be

$1854.688 - (12% of $1854.688)

$1854.688 - (0.12 × $1854.688)

Answer:

337 large buckets and 195 jumbo buckets were sold.

Step-by-step explanation:

x = the number of large buckets sold
y = the number of jumbo buckets sold

x + y = 532
(2.25x + 3.75y = 1489.50) x100 = 225x + 375y =148950

Thus,the slope is 7/9 in fraction and 0.80 (Nearest tenth) in decimal.

Answer:

The correct answer is y = -6x - 4

Step-by-step explanation:

The given equation of the line : y = -6x + 2

Now, the general equation of the line in the slope-intercept form is given by : y = mx + c

Now, comparing the given equation with the general form, We get slope, m = -6

We need to find the equation of the line which is parallel to the given line and since the slope of two parallel lines are equal so the slope of the required line will also be -6

And it passes through the point (-1, 2)

The required equation will be :

⇒ y - 2 = -6 × (x + 1)

⇒ y - 2 = -6x - 6

⇒ y = -6x - 4

Therefore, The required equation is y = -6x -4

Hence, The correct answer is. y = -6x - 4

Step-by-step explanation:

The company's EPS for Year 8 would be $2.50 and its retained earnings for Year 8 would be $20 million

Note: The options for the questions are as follows:

A. the company's total earnings for Year 8 would be $10 million (net income of $50 million less interest costs of $10 million less dividend payments of $30 million = $10 million).

B. the company's EPS for Year 8 would be $2.50 and its retained earnings for Year 8 would be $20 million (net income of $50 million less dividend payments of $30 million).

C. the company's credit rating would be no less than an A because operating profit is seven times higher than annual interest costs.

D. the company's EPS for Year 8 would be $5.50 and its retained earnings for Year 8 would be $10million (net income of $50 million less interest costs of $10 million less dividend payments of $30million).

E. the company's EPS for Year 8 would be $1.50 (operating profit of $70 million less interest costs of$10 million, less dividend payments of $30 million= $30 million divided by 20 million shares).

The question can now be answered as follows:

From the question, we can calculate the following:

EPS = Net income / Number of shares of common stock outstanding = $50 million / 20 million = $2.50

Dividend payments = Number of shares of common stock outstanding * Dividend per share = 20 million * $1. 50 = $30 million

Retained earnings = Net income - Dividend payments = $50 million - $30 million = $20million

Therefore, the correct option is B. the company's EPS for Year 8 would be $2.50 and its retained earnings for Year 8 would be $20 million (net income of $50 million less dividend payments of $30 million).

Answer:

To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.

Answer:

1) 21.24cm

2)19.8ft

3)22.84mm [2.284cm]

Step-by-step explanation:

To calculate the perimeter of a triangle, add the length of its sides.

1) perimeter = 5.4+8.84+7

=>    5.4+8.84+7 = 21.24,

 21.24cm

2) perimeter = 6.6 + 6.6 + 6.6  i.e  6.6* 3

=>    6.6 x 3 = 19.8

 19.8ft

3) perimeter = 8.3 + 4.9 + 9.64

=>     8.3 + 4.9 + 9.64 =  22.84

22.84mm or 2.284cm

AREA

1) it's a right triangle,

 =>    Area of a right triangle = 1/2 × base × height.

 =>    here, base is a and height is b

 =>    a = 7, b = 5.4

 =>   now we multiply it,  

 => 7*5.4 = 37.8

 => now multiply it with 1/2,  

 => 1/2 x 37.8 =  37.8/2

 => 37.8/2  = 18.9

2) it's an equilateral triangle,

18.8620

the formula is  √3 a^2/ 4

=>    √3* 6.6^2/ 4  

=>    75.4481/4 = 18.8620

3)  20.335

    base = a = 8.3

    height = b = 4.9

=>    8.3 * 4.9 = 40.68

=>     40.68/2 = 20.335

Answer:

A Quadrilateral is a 4 sided figure. In other words any shape that has 4 sides is a quadrilateral for example square, rectangle, trapezium etc

Step-by-step explanation:

Answer:

  108 cm²

Step-by-step explanation:

The composite shape can be divided as shown into a trapezoid and a triangle. The area of the shape is the sum of the areas of those parts.

__

The top portion of the shape is marked as a trapezoid with bases 12 cm and 6 cm, and height 6 cm. Its area is given by ...

  A = 1/2(b1 +b2)h

  A = 1/2(12 cm +6 cm)(6 cm) = 1/2(18 cm)(6 cm) = 54 cm²

__

The bottom portion of the shape is marked as a triangle. The triangle has a base of 12 cm and a height of (15 cm -6 cm) = 9 cm. Its area is ...

  A = 1/2bh

  A = 1/2(12 cm)(9 cm) = 54 cm²

__

The area of the composite figure is the sum of the areas of its parts:

  total area = trapezoid area + triangle area

  total area = 54 cm² +54 cm² = 108 cm²

The area of the logo is 108 cm².

Answer:

Answer 2 is correct because triangle ABC is the same as the original just that the position has changed

Answer:

750 grams of 60% alloy

Step-by-step explanation:

Define x = amount of 60% alloy and y = amount of 20% alloy

Equating the amounts of gold:

0.6x+0.2y = 1000(0.5)

Since there must be 1000 grams total:

x+y = 1000

Writing the 2 resulting equations together:

0.6x + 0.2y = 500

x + y = 1000

Multiply the first equation by 5:

3x + y = 2500

x + y = 1000

Subtracting the 2nd equation from the 1st:

2x = 1500

x = 750

Answer: 750 grams of 60% alloy

A function is when one input (x) has exactly one output (y).

A: is not a function because -4 is paired with two different y values.

B: is not a function because -4 is paired with two different y values.

C: is a function because each input (x) has exactly one output( y).

D: is not a function because -1 is paired with two different y values.

Answer:

x = -1

Step-by-step explanation:

(x1,y1) = (1,4) and m = 2

(y-y1)/(x-x1) = m

derive the linear function first before finding the zero.

(y-4)/(x-1) = 2

cross multiply

y-4 = 2(x-1)

y-4= 2x - 2

y = 2x - 2+4

y. = 2x + 2 is the linear equation

at y = 0 gives the zero

2x + 2 = 0

2x = -2

x = -2/2

x = -1 is the zero
