Answer:

The answer would be n=6.11

Step-by-step explanation:

The answer would be n=6.125

It is asking for the value of a variable, in this case, the variable is "n" and it can be found by isolating it on one side of the equation using basic mathematical operations such as division, multiplication, addition and subtraction. The question is asking to find the value of n, by solving the equation 103*n = 630.

To find the value of n, we can divide both sides of the equation by 103.

103 * n = 630

n = 630/103

n = 6.125

Therefore, The value of n is 6.125

Answer:

The function is odd

Step-by-step explanation:

Even functions and odd functions are those which satisfy particular symmetry relations as follows:

f(x) is even if f(-x) = f(x)

f(x) is odd if f(-x) = -f(x)

Not all functions are eligible for being even or odd.

Considering

[tex]f(x)=x^3+x^1[/tex]

Let's find f(-x)

[tex]f(-x)=(-x)^3+(-x)^1[/tex]

Since [tex](-x)^3=(-x)(-x)(-x)=-x^3[/tex]

And [tex](-x)^1=-x:[/tex]

[tex]f(-x)=-(x)^3-(x)^1[/tex]

Factoring by -1:

[tex]f(-x)=-((x)^3+(x)^1)[/tex]

The expression in parentheses if f(x), thus:

[tex]f(-x)=-f(x)[/tex]

And the function is odd.

Complete Question

Determine the probability P(1 or fewer) for a binomial experiment with n = 16 trials and the success probability p = 0.2. Then find the mean, variance, and standard deviation

Answer:

The probability is [tex]P(X \le 1 ) =  0.0484[/tex]

The mean is [tex]\mu = 3.2[/tex]

The variance is [tex]\sigma ^2 =2.56[/tex]

The standard deviation is  [tex]\sigma =1.6[/tex]

Step-by-step explanation:

From the question we are told that

    The probability of success is  p = 0.2

     The sample size is  n =  16

Generally this experiment follows a binomial distribution  

i.e  

         [tex]X  \~ \ \ \  B(n , p)[/tex]

and the probability distribution function for binomial  distribution is  

      [tex]P(X = x) =  ^{n}C_x *  p^x *  (1- p)^{n-x}[/tex]

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

Generally the the probability P(1 or fewer) is mathematically represented as

       [tex]P(X \le 1 ) = P(X = 0 ) + P(X = 1 )[/tex]

=>   [tex]P(X \le 1 ) =  [^{15}C_0 *  (0.2)^0 *  (1- 0.2)^{15-0}] + [^{15}C_1 *  (0.20)^1 *  (1- 0.20)^{15-1} ][/tex]

=>   [tex]P(X \le 1 ) =  [1 *  1*  0.0352 ] + [15 *  0.20 *  0.0439][/tex]

=>   [tex]P(X \le 1 ) =  0.0484[/tex]

Generally the mean for this experiment is mathematically represented as

     [tex]\mu = n * p[/tex]

=>  [tex]\mu = 16 * 0.2[/tex]

=>  [tex]\mu = 3.2[/tex]

Generally the variance is mathematically represented as

     [tex]\sigma ^2 = n * p * (1- p )[/tex]

=>  [tex]\sigma ^2 = 16 * 0.2 * (1- 0.2)[/tex]

=>  [tex]\sigma ^2 =2.56[/tex]

Generally the standard deviation is mathematically represented as

     [tex]\sigma = \sqrt{\sigma ^2 }[/tex]

=>    [tex]\sigma =1.6[/tex]

Answer: D. A polygon is concave if no diagonal contains points outside the polygon.

Explanation:

Choice A is true since "equiangular" means "equal angles"

Choice B is true since all sides are congruent, and all angles are congruent for a regular polygon

Choice C is true. The term "lateral" means "side".

Choice D is false because a convex polygon is one where all possible line segments contained in the polygon do not spill outside the polygon. Put another way, if points A and B are in a convex polygon, then every point on line segment AB is also in the polygon. Concave polygons don't have this feature. It is possible to draw a line segment where it spills outside the concave polygon.

We can deduce here that for a height of 145 cm, a likely interval of ages could be: 12 ≤ age ≤ 15

In mathematics, an inequality is a mathematical statement that expresses a relationship between two quantities, indicating that one quantity is greater than or less than another. It represents a comparison or a difference in values.

For a height of 145 cm, a likely interval of ages could be:

12 ≤ age ≤ 15

This range assumes that the child's height falls within the average height range for boys aged 12 to 15 years. However, it's important to consider that individual variations and growth patterns can influence a child's height, so this interval should be interpreted with caution.

Answer:

$0.80 per notebook

$0.40 per pencil

Step-by-step explanation:

To find the rate, we need to determine how much each item costs. That is, the cost per item.

Given that,

4 notebooks = $3.20

The cost of 1 notebook/rate = [tex] \frac{3.20}{4} = 0.80 [/tex]

Rate = $0.80 per notebook

Given that,

12 pencils = $4.80

The cost of 1 notebook/rate = [tex] \frac{4.80}{12} = 0.40 [/tex]

Rate = $0.40 per pencil.

Answer:

2 is the constant of proportionality in the equation y = 2x .

Step-by-step explanation:

Definition of constant of proportionality

When two variables are directly proportional to each others .

Let us assume that u and v .

u \propto vu∝v

Than the equation becomes u= kv

Where k is called the constant of proportionality .

Thus in the question x and y are proportional variables .

i.e

y \propto xy∝x

y = kx

Where k is called the constant of proportionality .

Compare the equation y = kx with y=2x .

Thus

k = 2

Therefore 2 is the constant of proportionality in the equation y = 2x

Answer:

1. (0,5), (0,9), (10,4), (10,0), (5,0)

2. [tex]Q_{max}=912[/tex]

[tex]Q_{min}=300[/tex]

Step-by-step explanation:

1.

In order to determine the coordinates of the vertices of the feasible region, we must first graph each of the inequalities. The feasible region is the region where all the inequalities cross each other. In this case it's the region shaded on the attached picture.

The first point is the intercept between the equations x=0 and x+y=5 so in order to find this first coordinate we need to substitute x=0 and solve for y.

0+y=5

y=5

(0,5)

The next point is the intercept between the equations x=0 and x+2y=18, so again, we substitute x for zero and solve for y:

0+2y=18

[tex]y=\frac{18}{2}[/tex]

y=9

(0,9)

The next coordinate is the intercept between the lines x=10 and x+2y=18, so we substitute x for 10 and solve for y:

10+2y=18

2y=18-10

2y=8

[tex]y=\frac{8}{2}[/tex]

y=4, so the oint is

(10,4)

The next point is the intercept between the lines x=10 and y=0, so the point is:

(10,0)

The final point is the intercept between the equations: y=0 and x+y=5. We substitute y for zero and solve for x:

x+0=5

x=5

so the point is:

(5,0).

2. In order to determine the maximum and minimum value of the function Q=60x+78y on the feasible region, we must evaluate it for each of the points found on part 1.

(0,5)

Q=60(0)+78(5)

Q=390

(0,9)

Q=60(0)+78(9)

Q=702

(10,4)

Q=60(10)+78(4)

Q=912

(10,0)

Q=60(10)+78(0)

Q=600

(5,0)

Q=60(5)+78(0)

Q=300

So now we compare the answers and pick the minimum and maximum results.

We get that:

[tex]Q_{max}=912[/tex]

when x=10 and y=4

and

[tex]Q_{min}=300[/tex]

When x=5 and y=0

The feasible region is the possible set of a constraint

(a) The coordinates of the vertices at the feasible region

The constraints are given as:

[tex]\mathbf{x \ge 0}[/tex]

[tex]\mathbf{y \ge 0}[/tex]

[tex]\mathbf{x \le 0}[/tex]

[tex]\mathbf{x + y\ge 5}[/tex]

[tex]\mathbf{x + 2y\ge 18}[/tex]

See attachment for the graph of the constraints

From the graph, the vertices are:

[tex]\mathbf{(x,y) \to (0,5), (0,9), (5,0)}[/tex]

(b) The minimum and the maximum values of objective function Q

The objective function is:

[tex]\mathbf{Q=60x +78y}[/tex]

Substitute [tex]\mathbf{(x,y) \to (0,5), (0,9), (5,0)}[/tex] in Q

[tex]\mathbf{Q=60(0) +78(5) = 390}[/tex]

[tex]\mathbf{Q=60(0) +78(9) = 702}[/tex]

[tex]\mathbf{Q=60(5) +78(0) = 300}[/tex]

Hence, the maximum and the minimum values are 702 and 300, respectively.
