Kareem's statement: 4:1 is equal to 12:9. Let's see if this is correct.

[tex]\bf Step ~1:[/tex]

We have to simplify the ratios. Since 4:1 is already simplified, we do not have to do anything with it. 12:9 could be simplified. To do so, we need to find the greatest common factor (GCF) of both numbers. The GCF of 12 and 9 is 3. Since 3 is the GCF for both numbers, we divide them by 3.

[tex]\bf 12 /3=4\\9/3=3[/tex]

First number: 4

Second number: 3

Ratio: 4:3

[tex]\bf Step~2:[/tex]

We compare the ratio 4:3 to 4:1. Since they have different values, they are not equivalent to each other.

[tex]\bf {Explanation~in~Step~1}[/tex]

4 : 1 and 12 : 9 are not equivalent

Kareem is wrong

Correct question:

Kareem says that the ratio 4:1 is equivalent to the ratio 12:9 because

4 + 8 = 12 and 1 + 8 = 9. Is Kareem correct? Explain how you know

4 : 1 is in its simplest form already

12 : 9

= 12/9

= 4/3

= 4 : 3

Therefore,

4 : 1 and 12 : 9 are not equivalent

Kareem is wrong based on his assumption that 4 + 8 = 12 and 1 + 8 = 9

Step-by-step explanation:

First of all, less than is the sign that points to the left,

Secondly, I'm guessing that y is actually V,

Before Ray gave Jan cards, she had 18,

so it is 18 plus V (the number of cards Ray gave her),

SO,

3(x + 6) = 5(x - 4)

Distribute on both sides.

3x + 18 = 5x - 20

Subtract 3x from both sides. Add 20 to both sides.

38 = 2x

Divide both sides by 2.

Answer: The function is not one-to-one

Step-by-step explanation:

An one-to-one function is such that no two elements in the domain correspond to the same element in the range.

Now, we have the function:

y = f(x) = round(x)

Which rounds x to the nearest whole number.

Now, to round to the next whole number we must look at the first number after the decimal point.

If that number is 5 or larger, we round up

If that number is smaller than 5, we round down.

Then, for example:

f(1.2) = 1

because the first number after the decimal point is smaller than 5.

and:

f(1.1) = 1

f(1.2) = 1

f(1.2423) = 1

f(1.348)  = 1

So we have a lot (if x is real, we have infinite) values of x that are maped into the same value in the range.

Then this can not be an one-to-one function.

Answer:

The wire is approximately 42feet long

Step-by-step explanation:

We can mentally sketch out the shape that is formed between the guy wire and the antenna tower. This is simply a right-angled triangle with the opposite side being the height of the antenna (30 feet). The adjacent side is the distance on the ground between the point where the wire was fastened and the base of the antenna.

The hypotenuse side is the length of the wire we are looking for.

Parameters are given as:

Opposite : 30ft

Adjacent: 30ft

Hypotenuse: x feet

The hypotenuse = [tex]\sqrt{opp^2 + adj^2}[/tex]

Hypotenuse =[tex]\sqrt{30^2+ 30^2} \approx 42ft[/tex]

Answer:

0.1028938

Step-by-step explanation:

Given the following :

Average gold production in Northern Nevada =3.2 grams per short ton (2000 pounds)

Value of gold is measured in Troy ounces (ozt)

1 Troy ounces = 31.1 grams(g)

Number of Troy ounces of gold extracted from one short ton of Nevada ore ; let the number be t:

1 ozt = 31.1 g

t = 3.2 g

Cross multiply :

31.1 × t = 3.2 × 1

31.1t = 3.2

t = 3.2 / 31.1

t = 0.1028938 ozt

Hence, On average, 0.1028938 ozt of gold is extracted from one short ton of Nevada ore

Answer:

a = - 1.1

Step-by-step explanation:

The condition for a single variable function f(x) to be decreasing is f'(x) < 0.

f(x) = 4/x^2 - 6x + 9

Then, differentiating with respect to x on both sides we get,

f(x) = 4(-2)(1/x^3) - 6 < 0

-8/x^3  - 6 < 0

8/x^3 + 6 > 0

{Dividing both sides with - 1 and hence the inequality sign changes}

8/x^3 > -6

8 > - 6x³ {Multiplying both sides with x³}

6x³ > - 8 {Interchanging the sides}

x^3 > -8/6

⇒ x > - 1.1

So,  a = - 1.1

Answer:

  a = 3

Step-by-step explanation:

The function can be written as ...

This has a vertical asymptote at x=3 and will be decreasing for all values of x to the right of that -- on the interval (3, ∞).

  a = 3

Answer:

a. What is the mean price? Round your answer to the nearest cent. $679.63

b. What is the median price? $689.50

c. What is the mode price? $699

Step-by-step explanation:

The mean price, rounded to the nearest cent is $679.63, the median price is $689.5 and the mode price is $699.

The mean is the ratio of the sum of all numbers and total numbers in the list. The median is the middle value in a list ordered in ascending order. The mode is the most frequently occurring value on the list.

In our question, given data:

$699, $599, $699, $680, $590, $720, $650, $800

Mean is found by dividing by sum all the prices and then divided by total terms.

Sum all prices = ($699 + $599 + $699 + $680 + $590 + $720 + $650 + $800) = $5437

Mean = [tex]\frac{5437}{8}[/tex] = $679.625

The round of mean value to the nearest cent is $679.63.

To find median, arrange the data list in ascending order and then find the middle value. Since in our data list, there are 8 terms (even). Therefore take average of the two middle values to find median.

Ascending order ⇒ 590, 599, 650, 680, 699, 699, 720, 800

Midian = [tex]\frac{680 + 699}{2}[/tex] = $689.5

Mode is the most frequently occurring value in the data list, in our data list, 699 comes twice.

∴ Mode = $699

Hence Mean = $679.63, Midian = $689.5, Mode = $699.
