Answer:

D the number 7 to the right of -4 on the number line

Answer:

[A] y(y + 4) - y = 6

[C] 4 b (b)=0

Step-by-step explanation:

First let know what is a quadratic functions(s):

A function is called Quadratic if it consist of  only one variable, maximum of three terms, and highest degree of the variable  in that Polynomial is 2.

Now let's go through the answer choices:

[A]  

y *(y+4) - y =6

y² + 4 y - y -6=0

y²+3 y -6=0

Thus, This is Quadratic Function.

[B]

3 x +2 + 6 x -1=0

9 x-1=0

Thus, This is not Quadratic Function

[C]

4 b*(b)=0

4 b²=0

Thus, This is Quadratic Function.

[D]

3 a- 7 =2 * (7 a-3)

3 a - 7=14 a - 6

3 a - 14 a = 7 -6

-11 a =1

Thus, This is not a Quadratic Function.

Hence, [A] and [C] are quadratic functions.

Answer:

66666666666666666666666666666666

Step-by-step explanation:

Answer:

F(k) = 2k e-2 / k!

Mean =µ = 2 x 3 = 6

f(k) = 6k e-6 / k!

F(2) = 22 e-2 / 2!

        = 0.2707

F(6) = 66 e-6 / 6!

        = 0.1606

f(5) = 45 e-4 / 5!

      = 0.1563

Step-by-step explanation:

Solution:

Given:

Mean = µ = 2 per time period

Poisson probability:

F(k) = µk e-µ / k!

(a) Poisson probability for one time period.

Put µ = 2 in formula, we get:

F(k) = 2k e-2 / k!

(b) Expected number of occurrence in three time period.

Mean of one time period is multiply with number of time period.

Mean =µ = 2 x 3 = 6

(c) Probability of occurrence in three time period.

Put the value of µ = 6 in the given formula, we get:

f(k) = 6k e-6 / k!

(d) Probability of two occurrences in one time period.

Put k = 2 in given formula:

F(2) = 22 e-2 / 2!

        = 0.2707

(e) Probability of six occurrences in three time period.

Put k = 6, in given formula, we get:

F(6) = 66 e-6 / 6!

        = 0.1606

(f) Probability of five occurrences in two time period.  

Mean of one time period is multiply by the number of time periods.

µ = 2 x 2 = 4

put k = 5 and µ = 4 in formula, we get:

f(5) = 45 e-4 / 5!

      = 0.1563

Answer:

D.  Makes both the top and bottom inequalities true

Step-by-step explanation:

System of linear inequalities

Consider these two inequalities:

2x+3y > 20

3x-2y > 5

The solution of the system consists of all the ordered pairs (x,y) that satisfy both inequalities. The ordered pair (3,5) makes the first inequality true because

2*3+3*5=21 and it's effectively greater than 20.

But that pair makes the second inequality false, since

3*3-2*5=-1 is not greater than 5.

Thus, the pair (3,5) is not part of the solution.

If we test the pair (6,2), we'll check both inequalities are true, thus (6,2) is part of the solution.

Thus, the correct answer to the question is

D.  Makes both the top and bottom inequalities true

Answer:

-7/8

Step-by-step explanation:

rate of change is the same as slope so -7/8

Answer:

Step-by-step explanation:

find the rate of change from the equation:

y = -7/8x + 3

use the formula: y = mx + b

where:

y = how far up the line goes

m = slope

x = how far along

b = Y-intercept

so the rate of change is the same as the slope

therefore, the slope = -7/8

Using interest equations, it is found that it will take 1.08 year more for Lydia's money to triple than for Lily's.

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which:

It is given by:

[tex]A(t) = Pe^{rt}[/tex]

For Lily, the parameters are as follows: r = 0.065, with continuous compounding. The time to triple is t for which A(t) = 3P, hence:

[tex]A(t) = Pe^{rt}[/tex]

[tex]3P = Pe^{0.065t}[/tex]

[tex]e^{0.065t} = 3[/tex]

[tex]\ln{e^{0.065t}} = \ln{3}[/tex]

[tex]0.065t = \ln{3}[/tex]

[tex]t = \frac{\ln{3}}{0.065}[/tex]

[tex]t = 16.90[/tex].

For Lydia, using compound interest, the parameters are: r = 0.06125, n = 12, hence:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]3P = P\left(1 + \frac{0.06125}{12}\right)^{12t}[/tex]

[tex](1.00510416667)^{12t} = 3[/tex]

[tex]\log{(1.00510416667)^{12t}} = \log{3}[/tex]

[tex]12t\log{(1.00510416667)} = \log{3}[/tex]

[tex]t = \frac{\log{3}}{12\log{(1.00510416667)}}[/tex]

[tex]t = 17.98[/tex]

17.98 - 16.9 = 1.08, hence, it will take 1.08 year more for Lydia's money to triple than for Lily's.

We have the Box-and-Whisker Plots for the data -

{22, 24, 24, 25, 26, 26, 27, 28, 28, 30} shown in the image.

We can identify the boxplot by the median calculation easily. We can find the median of the given data set as -

[M] = (26 + 26)/2 = (2 x 26)/2 = 26

Answer: Around 1.2 meters

Step-by-step explanation:

Answer:

Step-by-step explanation:

cos(2θ) - cosθ + 1 = 0

2cos²θ - 1 - cosθ + 1 = 0

2cos²θ - cosθ = 0

2cosθ(cosθ - 1/2) = 0

cosθ = 0, θ = π/2, 3π/2

cosθ = 1/2, θ = π/3. 5π/3
