Answer:

Step-by-step explanation:

We can rewrite the equation to standard form to see the center and semi-axis lengths.

  16x^2 -128x +y^2 +3y = -256

  16(x^2 -8x +16) +(y^2 +3y +2.25) = -256 +256 +2.25

  16(x -4)^2 +(y +1.5)^2 = 9/4 . . . . . write as squares

  (x -4)^2/(9/64) +(y +1.5)^2/(9/4) = 1 . . . . divide by 9/4

  ((x -4)/0.375)^2 +((y +1.5)/1.5)^2 = 1 . . . . put in useful form

In this form, we have ...

  ((x -h)/a)^2 +((y -k)/b)^2 = 1

where (h, k) is the center, 2a is the length of the axis in the x-direction, and 2b is the length of the axis in the y-direction. The required tangents are ...

  x = h±a

  y = k±b

For the given ellipse, the tangent lines are ...

Answer:

Alex (0.95), Tonya (0.90), Wilson (0.87), Octavia (0.80)

Step-by-step explanation:

To solve this, we have to convert all of the scores into either a decimal or a fraction. In this case, I will be solving all of them into decimals since it is easier.

Alex: 0.95

Octavia: 16/20 = 0.80

Tonya: 9/10 = 0.90

Wilson: 0.87

Therefore, we can order these from greatest score to least score.

Alex (0.95), Tonya (0.90), Wilson (0.87), Octavia (0.80)

Answer:

4.8

Step-by-step explanation:

area of rectangle = lxb = 8x

area of trapezium =  (a+b)h/2 = ( x+13)6 /2 = 3x + 39

Aea of whole figure = 91.8

8x + 3x+ 39 = 91.8

11x = 91.8-39

x= 52.8 /11 = 4.8

Answer:

number 3 will be right

Step-by-step explanation:

The correct statement is : y=2x+9

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: The linear equation is y=2x-4

Now the equation y=2x+9

equating both linear equations are

2x-4=2x+9

-4=9 which is not possible

Thus the incorrect equation that gives no solution is y=2x+9

Step-by-step explanation:

Area=Length × width or Length(width)

Solution :

Given :

[tex]$n_1=388$[/tex] , [tex]$x_1 = 294, \ n_2 = 566, \ x_2 = 38$[/tex]

Sample proportion, [tex]$(\hat p_1)=\frac{x_1}{n_1}$[/tex]

                                        [tex]$=\frac{294}{388}$[/tex]

                                       = 0.7577

Sample proportion, [tex]$(\hat p_2)=\frac{x_2}{n_2}$[/tex]

                                        [tex]$=\frac{38}{566}$[/tex]

                                       = 0.0671

For 95 % CI, z = 1.96

The confidence interval for the population proportion,

[tex]$p_1-p_2=(\hat p_1-\hat p_2)\pm z \left\{\sqrt{\frac{\hat p_1 \times (1- \hat p_1)}{n_1}+\frac{\hat p_2 \times (1- \hat p_2)}{n_2}}\right\}$[/tex]

           [tex]$=(0.7577-0.0671)\pm 1.96 \left\{\sqrt{\frac{0.7577 \times (1- 0.7577)}{388}+\frac{0.0671 \times (1- 0.0671)}{566}}\right\}$[/tex]

[tex]$=0.6906 \pm 1.96 \times \left 0.0241$[/tex]

= [tex]$0.6906 \pm 0.0472 $[/tex]

Lower limit : 0.6906 - 0.0472 = 0.6434

Upper limit : 0.6906 + 0.0472 = 0.7378

Answer:

330 cubic feet

Step-by-step explanation:

The formula for Volume is L (length) x W (width)  x H (Hight)

So all we have to do is multiply the numbers for each floor and then add them together.

5 x 3 = 15 15 x 6 = 90

6 x 5 = 30 30 x 8 = 240

240 + 90 = 330

Now add you cubic feet since volume is cubed.

330 cubed feet

Thus, your answer is 330 cubed feet.

Hope this helps! :)

Answer:

[tex] R = \frac {3ST}{2S + T} [/tex]

Step-by-step explanation:

Given the equation;

[tex] \frac {3}{R} - \frac {1}{S} = \frac {2}{T} [/tex]

Rearranging the equation, we have;

[tex] \frac {3}{R} = \frac {2}{T} + \frac {1}{S} [/tex]

Lowest common multiple (LCM) of S and T is ST.

[tex] \frac {3}{R} = \frac {2S + T}{ST} [/tex]

Cross-multiplying, we have;

[tex] 3ST = R(2S + T) [/tex]

Making R, the subject of formula;

[tex] R = \frac {3ST}{2S + T} [/tex]

Answer:

N = 50

Step-by-step explanation:

Of means multiply and is means equals

3/5 * N = 30

Multiply each side by 5/3 to isolate N

5/3 * 3/5 * N = 30 * 5/3

N = 50

Domain: All real numbers, or (-∞,∞) depending on how you want to write it.

Range: [-4, ∞)

Vertex: (-2, -4)

Axis of symmetry: x = -2

Interval of increase: (-2, ∞)

Interval of decrease: (-∞, -2)

Y-int: (0, 0)

X-int/Zero/Solution(s): (-4, 0) and (0, 0)

For a polynomial function like this, which is a quadratic function, the domain is always negative infinity to positive infinity, or all real numbers.

The range is the lowest y-value to the highest y-value. The lowest y-value for this is at the vertex, but the function has no upper limit for the y-value.

The vertex is the point that you can very clearly see is at the tip of the graph.

Axis of symmetry is the vertical line that splits the graph in half at the vertex.

Interval of increase is the interval x values for which the function is increasing. The function increases to the right of the vertex.

Interval of decrease is to the left of the vertex.

The y-intercept is clearly (0, 0), where the graph intersects the y-axis.

The x-intercepts are also clear, since you can see where the graph intersects the x-axis.

Answer:

d

Step-by-step explanation:

because the 15ft length is the same as x

Based on the graph, we can see that the possible values of X are 2, 3, and 4. The probability of X = 2 is 0.36, the probability of X = 3 is 0.48, and the probability of X = 4 is 0.16.

Probability is a measure of the likelihood of an event occurring. It is usually expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

Based on the graph, we can see that the possible values of X are 2, 3, and 4. The probability of X = 2 is 0.36, the probability of X = 3 is 0.48, and the probability of X = 4 is 0.16.

We can also see that the distribution is skewed to the right, meaning that the most likely outcome is X = 3, which occurs with a probability of 0.48.

This makes sense, since the chimpanzee is more likely to have 2 babies in one pregnancy and 1 baby in the other, which would result in a total of 3 babies.

Thus, the graph provides a visual representation of the probability distribution for X and helps us to understand the relative likelihood of each possible outcome.

#SPJ2

Answer:

240

Step-by-step explanation:

If 75% is 180, we need to find the remaining 25%.

Obviously, 25 is 1/3 of 75 (and "of" is another word for times) meaning that to find 25%, multiply 75% by 1/3.

Since 75% = 180, we do:

180 x 1/3

60

Now add these two values together to get:

180 + 60 = 240

The answer is 240
