Answer:

26.6667

Step-by-step explanation:

.15x=100

Divide each side by .15.

x=666.6667

.04(666.6667)=26.6667

Answer:

26(approx.)

Step-by-step explanation:

15/100 times x = 100

3/20 times x = 100

3x/20 = 100

3x = 2000

X= 666 2/3

So,

4/100 x 666.67

1/25 x 666.67 = 26

Answer:

1. y = -2n + 9

2. y = (1/2)x + 1/2

Step-by-step explanation:

1.

The equation of a line is denoted by y = mx + b, where m is the slope and b is the y-intercept.

Slope is calculated by taking two coordinates and dividing the difference of the y-coordinates by the difference of the x-coordinates. The y-intercept is where the line intersects the y-axis.

Let's choose any two points on the line: (4, 1) and (3, 3). Then:

slope = m = (3 - 1) / (3 - 4) = 2 / (-1) = -2

Now, we can also see that at the point (0, 9), the line intersects the y-axis, so that means b = 9.

The equation is thus y = -2n + 9.

2.

Let's again choose any two points to find the slope: (1, 1) and (3, 2). Then:

slope = m = (2 - 1) / (3 - 1) = 1/2

We can see that the line crosses the y-axis at the point (0, 1/2), so that means b = 1/2.

The equation is thus y = (1/2)x + 1/2.

Answer:

4

Step-by-step explanation:

2√x, √x + 1, 2√x + 1 sides of triangle

√x= y

2y, y+1, 2y+1

(2y)²+(y+1)²= (2y+1)²

4y²+y²+2y+1= 4y²+4y+1

y²-2y=0

y=0 (discarded as side can't be zero) or y= 2

so √x=2 ⇒ x= 4

Answer:

x = -2

y = 4

Step-by-step explanation:

6x-5y=-32

-7x+8y=46

Solve for x in the first equation.

6x = -32 + 5y

x = (-32 + 5y) /6

x = 5/6y - 16/3

Put x as 5/6y - 16/3 in the second equation and solve for y.

-7(5/6y - 16/3) +8y = 46

-35/6y+112/3 +8y = 46

13/6y + 112/3 = 46

13/6y = 46 - 112/3

13/6y = 26/3

y = 26/3 × 6/13

y = 4

Put y as 4 in the first equation and solve for x.

6x-5(4)=-32

6x-20 = -32

6x = -32+20

6x = -12

x = -12/6

x = -2

Step-by-step explanation:

since the right triangles are similar

hyp       leg

------ = ---------

leg      part

(6+8)        x

--------- = ----------

x                 2

Using cross products

x^2 = (6+8) *2

x^2 = 28

Take the square root of each side

x = sqrt(28)

x = sqrt(4) sqrt(7)

x = 2 sqrt(7)

Answer:

3018

Step-by-step explanation:

an = a1 + (n-1)d

a1 is the first term in the sequence = 24

n is the term number which is 500

d is the common difference

Take the second term and subtract the first term to find the common difference

d = 30-24 = 6

a500 = 24 + (500-1) *6

          =24+ 499*6

          =24 + 2994

          =3018

Answer:

3018 is the correct answer.

The experimental probability could be more, the same or less than the theoretical probability of rolling a 1 (which is 1/6).  

The larger your sample (i. e., as you go beyond 60 tosses), the closer the two different probabilities are likely to be.  (Think:  Law of Large Numbers).

Answer:

ŷ = -0.895X + 13.600

Slope = -0.9

Intercept = 13.6

r = - 0.964

Step-by-step explanation:

Given the data:

X- 10.1 9.8 9.7 9.4 8.9 8.7 8.4 8.1

Y- 4.3 4.8 5.3 5.2 5.6 5.8 6.1 6.3

Inputting the data given into the online regression calculator :

The equation of line of best fit :

ŷ = -0.895X + 13.600

Slope = - 0.9(to the nearest tenth)

Intercept = 13.6 (to the nearest tenth)

The correlation Coefficient 'r' of the data supplied is - 0.9643, which implies that a strong negative correlation exists between the dependent and independent variables.

r = - 0.964 (to the nearest thousandth)

Inputting the data into the STAT then Fit Data function of the HP 50g

Graphing Calculator.

The meaning of the strong negative correlation is that the x-values

of the data is decreasing, while the corresponding y-values of the data

increasing.

Reasons:

The least squares regression line equation is the best fit line for the data

The formula for the least squares regression line is [tex]\hat Y = b \cdot X + a[/tex]

Where;

[tex]b = \dfrac{n \cdot \sum X \cdot Y - \left (\sum X \right )\left (\sum Y \right )}{n \cdot \sum X^{2} - \left (\sum X \right )^{2}}[/tex]

[tex]a = \dfrac{\sum Y - b \cdot \sum X}{n}[/tex]

n = The sample size

Inputting the given data into the function Fit Data on a graphing calculator,

by editing ∑DAT.

The left column, represent the x-values, and right column represent the y-

values as follows;

[tex]\begin{array}{|c|cc|} \mathbf{Column \ 1}&&\mathbf{Column \ 2}\\10.1&&4.3\\9.8&&4.8\\9.7&&5.3\\9.4&&5.2\\8.9&&5.6\\8.7&&5.8\\8.4&&6.1\\8.1&&6.3\end{array}\right][/tex]

After inputting the data as above, press enter.

Move the pointer to the Model options line, select choose to choose the

Linear Fit model by selecting OK.

Select OK again for the calculator to do the calculations.

The least squares regression line equation given by the calculator is

presented as follows;

y = 13.5998272884 - 0.894645941278·x

The slope and the y-intercept rounded to the nearest tenth gives;

Correlation coefficient:

The correlation coefficient is given from the data using the following

formula;

[tex]r = \dfrac{n \cdot \sum X \cdot Y - \left (\sum X \right ) \cdot \left (\sum Y \right )}{\sqrt{n \cdot \sum X^{2} - \left (\sum X \right )^{2}\times n \cdot \sum Y^{2} - \left (\sum Y \right )^{2}}}[/tex]

From the graphing calculator, we have the correlation coefficient, given as

follows;

Correlation: (-0.964276229529)

Therefore, to the nearest thousandth;

The high negative value of the correlation coefficient indicates a strong

and near perfect relationship between the variables, x, and y, such that we

have;

Answer:

36 feet

Step-by-step explanation:

Let us first find the area of the of the flower bed. It is a rectangle, so:

A = 18 * 4.5 = 81 square feet

The square flower bed has the same area, therefore, the length of the sides of the flower bed can be gotten. The area of a square is:

[tex]A = L^2[/tex]

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

L = 9 feet

Next, we need to find the perimeter of the square flower bed:

P = 4L

=> P = 4 * 9 = 36 feet

He needed 36 feet of fence to enclose the entire square flower bed.

Answer:

The correct option is;

(B) 30

Step-by-step explanation:

The equations are;

x² - 2·m·x - 5·n = 0.............(1)

Solution = p, q

x² - 2·p·x - 5·q = 0..............(2)

Solution = m, n

For equation (1), we have;

x² - 2·m·x - 5·n = 0 = (x - p)·(x - q)

x² - 2·m·x - 5·n = x² -x·p - x·q + q·p = x² -x·(p + q) + q·p

2·m = p + q..............(3)

5·n = -q·p..............(4)

Given the similarity between equation (1) and (2), we have;

2·p = m + n..............(5)

5·q = -m·n..............(6)

Therefore;

m = (p + q)/2

n = -q·p/5

Substituting the value of m and n in equation (5) and (6), we have;

2·p = (p + q)/2  - q·p/5.............(7)

5·q = (p + q)/2·q·p/5.............(8)

Making q the subject of equation (7) gives;

[tex]q = \dfrac{-7.5 \cdot p}{p -2.5}[/tex]

Substituting the value of q above in equation (8) gives;

[tex]-\dfrac{75\cdot p}{2\cdot p-5}=-\dfrac{3\cdot p^{4}-30\cdot p^{3}}{4\cdot p^{2}-20\cdot p+25}[/tex]

By cross multiplying and collecting like terms we have;

6·p⁵ -75·p⁴-150·p³+1500·p²-1875·p = 0

Which gives

(p+0)(p-1.91)(p-2.5)(p+5)(p-13.1)

p = 1.91 or 2.5 or -5 or 13.1

q = 24.27 or undef or -5 or -9.27

m = 13.09 or undef or -5 or 1.95

n = -9.27 or undef or -5 or -24.29

Therefore, p + q + m + n = 1.91 + 24.27 + 13.09 + (-9.27) = 30

The correct option is (B) 30

Answer:

Option (3)

Step-by-step explanation:

Explicit formula of the sequence is,

[tex]a_n=3^n+4[/tex]

From this explicit formula,

First term of the sequence will be,

[tex]a_1=(3^1)+4[/tex]

[tex]a_1=7[/tex]

Second term of the sequence,

[tex]a_2=(3^2)+4[/tex]

[tex]a_2[/tex] = 13

3rd term of the sequence,

[tex]a_{3}=(3^3)+4[/tex]

   = 31

Sequence formed,

7, 13, 31 ..........

From the given options,

Recursive formula,

[tex]a_n=3a_{n-1}-8[/tex]

[tex]a_2=3(a_1)-8[/tex]

[tex]a_2=3(7)-8[/tex]

[tex]a_2=21-8[/tex] = 13

[tex]a_3=3a_2-8[/tex]

[tex]a_3=3a_2-8[/tex]

[tex]a_3=3(13)-8[/tex]

    = 39 - 8

    = 31

Sequence formed from this recursive formula will be,

7, 13, 31........

Answer:

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

When you dilate by a factor of 0, this doesn't really make sense because the length of each side is multiplied by 0, and the shape basically doesn't exist anymore. When you multiply by a scale factor of 1, the figure does not change in size at all. When you dilate by a scale factor of 5, each side length gets 5 times larger, meaning that this is not a reduction. Hope this helps!
