Please don't ask me to download the answer

Answers

Answer 1

A two-way relative frequency table consists of two types of data or data in two categories one relating to the columns and the other relating to the rows.

Shift Response

Yes No Total

Day

67% 33% 100%

Night

23% 77% 100%

Total

45% 55% 200%

In this table there is data relating to two categories day/ night and yes/no.

Along the rows the percentages of the day/night data are calculated.

Along the columns the percentages of the yes/no data are calculated.

Shift Response

Yes No Total

Day 67/100*100 33/100 *100 100

= 67% =33% 100%

Night 23/100*100 77/100*100 100

= 23% =77% 100%

Total 90/200 *100 110/200*100 200

= 45% = 55% 200%

These calculations are done by dividing the row cells by their respective row totals.

Similarly the columns cells are filled by dividing the column cells with their respective column totals.

If you buy three of the ABC bonds with $10 commission for each, how much will it cost? a. $3142.50 b. $1047.50 c. $3172.50 d. $1077.50

Answers

The computation shows that the cost of each bond is A. $3142.50.

How to solve the cost?

From the complete information given, the price of the bond is given as $2856.80 each.

Therefore, with the commission, the price will be:

= $2856.80 + (10% × $2856.80)

= $2856.80 + $285.68

= $3142.50

In conclusion, the cost of each bond is $3142.50.

How many real solutions are there to the equation: x + y = 10

don't forget the explanation?

Answers

Answer:

An infinite amount

Step-by-step explanation:

The domain and range of the equation [tex]x+y=10[/tex] are both [tex](-\infty, \infty)[/tex] or all real numbers ([tex]\mathbb{R}[/tex]). This means the equation takes on any real value for [tex]x[/tex] and [tex]y[/tex]. Therefore, there are an infinite number of real solutions to the equation.

Conceptually this makes sense. For any number we plug in for [tex]x[/tex], we can change [tex]y[/tex] to make [tex]x+y=10[/tex] true. Since there are an infinite number of numbers, there are an infinite number of values we can plug in for [tex]x[/tex] and [tex]y[/tex].

Billy likes to go cycling.
His bike has wheels of diameter 80 cm.

He has a counter on his bike which
counts the number of revolutions
the wheels make.

One day the counter shows 350 revolutions.

How far has Billy cycled?

Give your answer to the nearest metre.

Answers

Answer:

560 metres

Step-by-step explanation:

80 cm in metres is 0.8 metres.

After 1 revolution any point on the wheel will be back to the original position before moving. 0.8 times 2, which gives us 1.6 metres. In 1 revolution the bike travels 1.6 metres.

Now 1.6 metres times 350 gives us 560.

So the answer is 560 metres.

A polygon with area 10 square units is dilated by a scale factor of k. Find the area of the image for each value of k.
a k=4
square units
b. k=1.5
square units
ck=1
square units

Answers

Answer:

a = 160 square units

Step-by-step explanation:

The areas of the image are 160, 22.5 and 10 square units

The area of the polygon is given as:

A =10 square unit

The area of the image of the polygon is calculated as:

[tex]A_k = A * k^2[/tex]

When k = 4, we have:

[tex]A_4 = 10 * 4^2[/tex]

[tex]A_4 = 160[/tex]

When k = 1.5, we have:

[tex]A_{1.5} = 10 * 1.5^2[/tex]

[tex]A_{1.5} = 22.5[/tex]

When k = 1, we have:

[tex]A_{1} = 10 * 1^2[/tex]

[tex]A_{1} =10[/tex]

Hence, the areas of the image are 160, 22.5 and 10 square units

A rectangular swimming pool is 8 ft deep. One side of the pool is 3.5 times longer than the other. The amount of water needed to fill the swimming pool is 2800 cubic feet. Find the dimensions of the pool. The smaller dimension of the pool is enter your response here ft and the larger dimension is enter your response here ft.

Answers

Answer:

smaller: 10 ftlarger: 35 ft

Step-by-step explanation:

The volume of the pool is given by ...

V = LWH

Here, we have ...

V = 2800 ft³

H = 8 ft

L = 3.5W

Filling in these values, we have ...

2800 ft³ = (3.5W)(W)(8 ft)

100 ft² = W² . . . . . . . . . . . . divide by 28 ft

W = √(100 ft²) = 10 ft

L = 3.5W = 35 ft

The pool is 10 ft by 35 ft.
