Answer: They are diffrent

Step-by-step explanation: The logistic equation was first published by Pierre Verhulst in 1845. This differential equation can be coupled with the initial condition P(0) = P0 to form an initial-value problem for P(t). Suppose that the initial population is small relative to the carrying capacity. Then P K is small, possibly close to zero.

The logistic regression coefficients are the coefficients b 0, b 1, b 2,... b k of the regression equation: An independent variable with a regression coefficient not significantly different from 0 (P>0.05) can be removed from the regression model (press function key F7 to repeat the logistic regression procedure).

The length of a rectangle is 7 meters longer that it’s width. What is the width of this rectangle if it’s perimeter is equal to

dolphi86 [110]

The width of rectangle is 21 meters.

Step-by-step explanation:

Given,

Perimeter of rectangle = 98 meters

Width of rectangle = w

Length of rectangle = w+7

Perimeter of rectangle = 2(Length+Width)

Perimeter = $2(w+7+w)$

$98=2(2w+7)\\98=4w+14\\98-14=4w\\84=4w\\4w=84$

Dividing both sides by 4

$\frac{4w}{4}=\frac{84}{4}\\w=21$

Width of rectangle = 21 meters

The width of rectangle is 21 meters.

Solve to find x and y in the diagram.

Kipish [7]

Considering the given information in the question, the value of x is $12^{o}$ , and that of y is $7.5^{o}$ .

A transversal is a line that cuts through two given parallel lines. Thus it intersects each parallel line at a point, forming four angles each.

From the given information in the question, it can be inferred that:

the given bottom right angle of the first intersection and the bottom right angle with the second intersection are congruent (corresponding angle property).

So that,

$(5x+4y)^{o}$ = $(12y)^{o}$

$5x^{o}$ = $12y^{o}$ - $4y^{o}$

$5x^{o}$ = $8y^{o}$ ............ 1

Also given that the top right angle at the second intersection is a right angle, then;

$12y^{o}$ + $90^{o}$ = $180^{o}$ (sum of angles on a straight line)

This implies that;

$12y^{o}$ = $180^{o}$ - $90^{o}$

$12y^{o}$ = $90^{o}$

So that,

y = $\frac{90}{12}$

y = $7.5^{o}$

Thus substituting the value of y in equation 1, we have;

$5x^{o}$ = $8y^{o}$ ........ 1

= 8(7.5)

5x = 60

x = $\frac{60}{5}$

x = $12^{o}$

Therefore, x = $12^{o}$ and y = $7.5^{o}$

How many ways can we arrange 3 tulips, 2 yellow roses, and 8 lilies to form a border around a garden?

Elina [12.6K]

Answer:

The mentioned flowers can be arranged in 48 different ways.

Step-by-step explanation:

To determine in how many ways the mentioned flowers can be arranged (3 tulips, 2 yellow roses, and 8 lilies), all the variables must be multiplied together, and the result will be the number of possibilities for organizing them. Thus, the resolution of this question is the following:

3 x 2 x 8 = X

6 x 8 = X

48 = X

Therefore, the mentioned flowers can be arranged in 48 different ways.

Find the number by which 4732 should be divided to get perfect square.

ElenaW [278]

Answer:

The required number is 7.

Dividing by this gives the perfect square 676.

Step-by-step explanation:

Finding the prime factors:

2) 4732

2) 2366

7) 1183

13)169

So 4372

= 2^2 * 7 * 13^2

= 4 *169 * 7

= 676 * 7

Now 676 is a perfect square so the answer is 7.

= 1283 * 4.

Answer is 1283.
