Answer:

[tex]Relative\ Frequency = 0.04[/tex]

Step-by-step explanation:

Given

Cost of Textbooks ---- Frequency

$25 up to $35  -----      2

$35 up to $45 -------     5

$45 up to $55  -------    7

$55 up to $65   ------    20

$65 up to $75   ----   -- 16

Required

Determine the relative class frequency for the $25 up to $35 class

First, we need to get the total frequency

[tex]Total = 2 + 5 + 7 + 20 + 16[/tex]

[tex]Total = 50[/tex]

Next, is to write out the frequency of $25 up to $35 class

[tex]Frequency = 2[/tex]

Divide this frequency by the total frequency; This gives the relative frequency

[tex]Relative\ Frequency = \frac{Frequency}{Total}[/tex]

[tex]Relative\ Frequency = \frac{2}{50}[/tex]

[tex]Relative\ Frequency = 0.04[/tex]

Hence;

Answer:

B. Dependent samples

Step-by-step explanation:

Dependent samples occur when you have two samples that do affect one another. Dependent samples are paired measurements for one set of items.

While independent samples occur when you have two samples that do not affect one another.

Independent samples are measurements made on two different sets of items.

3. -4n = -16

    n = 4

4. 6h = 36

    h= 6

Answer:

$1615.05

Step-by-step explanation:

First, you need to determine the total cost for taking 15 credit hours:

Total cost=660+(113.67*15)

Total cost=$2,365.05

Now, you can subtract from that the amount of the grant and the scholarship you receive:

$2,365.05-$350-$400=$1615.05

According to this, the answer is that if you are taking 15 credit hours, you will need to pay $1615.05 for your classes next semester.

Answer: balance is -44 dollars

This indicates he owes 44 dollars

=======================================================

Explanation:

21 + (-30) = -9 is the balance if we don't account for the overdraft fee

If we do account for the overdraft fee, then -9 + (-35) = -44 is the bank balance.

Note how I'm using negative values to indicate balances in which Nick owes money, rather than it's the amount of money he has. So he owes the bank $44.

------------

A slightly different way to get the answer is to say

21-30 = -9

-9-35 = -44

This is because adding a negative is the same as subtraction.

Answer:

2/5 =y

Step-by-step explanation:

8/5 = 4y

Divide each side by 4

8/5 * 1/4 = 4y/4

8/4 *1/5 = y

2 *1/5 = y

2/5 =y

Answer:

y=2/5

Step-by-step explanation:

8/5=4y

y=(8/5)/4

y=(8/5)(1/4)

y=8/20

simplify

y=2/5

Answer:

0.15 ( E )

Step-by-step explanation:

Assuming

video game to be : V

electronics : E

clothing : C

From the content of the question

V = 2c

hence E = 2/3 V - 1/5 C  

              = 2/3 ( 2c ) -  1/5 c

              = [tex]\frac{17c}{15}[/tex]

therefore : V = 2c  and E =  17c / 15

assuming the number of clothing ( c ) = 15

V = 2*15 = 30  and E = ( 17 *15 ) / 15 = 17

Total number of items sold =  V + C + E = 30 + 15 + 17 = 62

from here we can determine the probability that of the five items independently sold that there are 3 video game, 1 electronic item and 1 clothing item

attached below is the remaining part of the solution

Answer:

Step-by-step explanation:

Answer: r=√6 or r≈2.45.

Step-by-step explanation:

To find the radius, you first need to know the equation of a circle.

Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex]

Now that we know the equation of the circle, we can use it to find the radius of the given equation.

3.5(x+2.2)²+3.5(y-11.1)²-21=0

So far the equation looks pretty similar with the exception of the bolded areas. To get rid of them, we need to use our algebraic properties.

3.5(x+2.2)²+3.5(y-11.1)²-21=0                    [add both sides by 21]

3.5(x+2.2)²+3.5(y-11.1)²=21                       [factor out 3.5]

3.5((x+2.2)²+(y-11.1)²)=21                           [divide both sides by 3.5]

(x+2.2)²+(y-11.1)²=6

Now, our equation is the same as the one posted above. You may think that 6 is our radius, but if you look closely, the equation is equal to r². Therefore, 6 is actually r², not r.

r²=6                                                             [square root both sides]

r=√6

Finally, we have the final answer, r=√6 or r≈2.45.

Answer:

[tex]\displaystyle V_\text{right} \approx 1696\text{ units}^3[/tex]

Step-by-step explanation:

Recall that the volume for an oblique cylinder is the same for the volume of a right cylinder. That is:

[tex]\displaystyle V_\text{right} = V_\text{oblique} = \pi r^2h[/tex]

Hence, find the volume of the oblique cylinder:

[tex]\displaystyle \begin{aligned} V_\text{oblique} & = (3.14)(6)^2(15) \\ \\ & = 1695.6 \text{ units}^3 \\ \\ &\approx 1696\text{ units}^3\end{aligned}[/tex]

Therefore:

[tex]\displaystyle V_\text{right} \approx 1696\text{ units}^3[/tex]

In conclusion, the volume of the right cylinder is about 1696 units³.

Answer:

[tex]perimeter=90[/tex]

Step-by-step explanation:

We know that the length is four times the width, so:

[tex]l=4w[/tex]

We also know the area, which is 324 m². The formula for area:

[tex]A=l*w[/tex]

Insert the known values:

[tex]324=(4w)*w[/tex]

Solve for w. Simplify by removing parentheses:

[tex]324=4w*w\\324=4w^2[/tex]

Divide 4 from both sides to isolate the variable:

[tex]\frac{324}{4}=\frac{4w^2}{4} \\\\81=w^2[/tex]

Find the square root of both sides:

[tex]\sqrt{81} =\sqrt{w^2} \\\\w=9[/tex]

The width is 9 m.

We know the width. Now find the length by using the area formula and inserting known values:

[tex]324=l*9[/tex]

Solve for l. Divide both sides by 9:

[tex]\frac{324}{9}=\frac{l*9}{9}\\\\ l=36[/tex]

The length of the rectangle is 36. (You can check: 4 times 9 is 36)

Now find the perimeter:

[tex]P=2l+2w[/tex]

Insert values:

[tex]P=2(36)+2(9)\\\\P=72+18\\\\P=90[/tex]

The perimeter is 90 m.

Answer:

0.68

Step-by-step explanation:

The formula for z test is given above as:

z = p' - p/√(pq/n)

p' = sample proportion

= Number of infested samples(trees)/ Number of samples

p' = 127/1000 = 0.127

p = 12% = 0.12

q= 1 - 0.12 = 0.88

n = number of samples = 1000

z = 0.127 - 0.12/√(0.88 × 0.12/1000)

z = 0.007/√0.0001056

z = 0.007 /0.0102761861

z = 0.6811865737

Therefore, the z test statistic is approximately ≈ 0.68

C. Graph C

Step-by-step explanation:

To easily find out which graph correctly displays the data from the list and table, note, the frequency of each color that in ascending order.

The color with the highest frequency would have the longest bar, followed by the 2nd highest, then the third, and so on. Thus, frequency should tally with the length of the bar.

From the table given, the top 3 are:

Pink polka dots => 12

Purple => 8

Ted and orange stripes => 7

Green => 6

Blue and gray => 4

Yellow => 3

The graph that has length of bars that corresponds to the frequency of the colors is graph C

Answer:

[tex](a)[/tex]  [tex]dy = 5sec^2(5t) \ dt[/tex]

[tex](a) \ dy = \frac{-20v}{(5+v^2)^2} \ dt[/tex]

Step-by-step explanation:

Given;

(a) y = tan(5t)

[tex](b) \ y = \frac{5-v^2}{5+v^2}[/tex]

Solving for (a)

y = tan(5t)

let u = 5t          

⇒y = tan(u)

du/dt = 5

dy/du = sec²u

[tex]\frac{dy}{dt} =\frac{dy}{du} *\frac{du}{dt} \\\\\frac{dy}{dt} = sec^2(u)*5\\\\\frac{dy}{dt} = 5sec^2(u)\\\\\frac{dy}{dt} = 5sec^2(5t)[/tex]

[tex]dy = 5sec^2(5t) \ dt[/tex]

Solving for b;

let u = 5 - v²

du/dv = -2v

let v = 5+ v²

dv/du = 2v

[tex]\frac{dy}{dv} = \frac{vdu - udv}{v^2} \\\\\frac{dy}{dv} = \frac{-2v(5+v^2) - 2v(5-v^2)}{(5+v^2)^2}\\\\\frac{dy}{dv} = \frac{-10v-2v^3-10v+2v^3}{(5+v^2)^2}\\\\[/tex]

[tex]\frac{dy}{dv} = \frac{-10v-10v}{(5+v^2)^2}\\\\\frac{dy}{dv} = \frac{-20v}{(5+v^2)^2}\\\\dy = \frac{-20v}{(5+v^2)^2} dt[/tex]
