Answer:

[tex]SE_{\bar x} = 0.311[/tex]

Step-by-step explanation:

Given

[tex]n=5[/tex]

[tex]\bar x = 41\%[/tex]

[tex]\sigma^2= 48.5\%[/tex] --- variance

Required

The standard error of the sample mean

This is calculated as:

[tex]SE_{\bar x} = \frac{\sigma}{\sqrt n}[/tex]

This can be rewritten as:

[tex]SE_{\bar x} = \frac{\sqrt{\sigma^2}}{\sqrt n}[/tex]

So, we have:

[tex]SE_{\bar x} = \frac{\sqrt{48.5\%}}{\sqrt 5}[/tex]

Rewrite as:

[tex]SE_{\bar x} = \sqrt{\frac{48.5\%}{5}}[/tex]

[tex]SE_{\bar x} = \sqrt{0.097}[/tex]

[tex]SE_{\bar x} = 0.311[/tex]

The answer is "The discriminant is positive"

Step-by-step explanation:

When the discriminant is positive there is two real solutions.

When the discriminant is equal to 0, there is one real solution.

When the discriminant is negative, there is no real number solutions.

Answer:

k = - 5

Step-by-step explanation:

Given that (x - 1) is a factor of p(x) then p(1) = 0, that is

2 - 3 + 6 + k = 0

5 + k = 0 ( subtract 5 from both sides )

k = - 5

Step-by-step explanation:

[tex]\frac{n}{2} +10=2n-4[/tex]

The equation represent the given situation is n/2 -10 =2n-4.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Given that, One half of the number n increased by 10.

That is n/2 -10

Four less than twice the number.

Here, 2n-4

Now, n/2 -10 =2n-4

n/2 -2n = -4+10

(n-4n)/2 = 6

-3n=12

n=-4

Therefore, the equation represent the given situation is n/2 -10 =2n-4.

Answer:

C

Step-by-step explanation:

y=x(1/2)^x

Answer:

52.37 – 46.37 = y

8y = 48

Step-by-step explanation:

Choose all the equations that are true if y = 6. 52.37 – 46.37 = y 45y =445 8y = 48 3.2 + y = 9 y ÷ 4 = 24

We solve for y in all the equations :

52.37 – 46.37 = y

52.37 – 46.37 = 6 (True)

45y =445

Divide both sides by 45

45y/45 = 445/45

y = 9.888 (False)

8y = 48

y = 48/8

y = 6 (True)

3.2 + y = 9

y = 9 - 3.2

y = 5.8 (false)

y ÷ 4 = 24

y/4 = 24

y = 24 * 4 = 96 ( false)

Answer:

48 ft

Step-by-step explanation:

Here, we want to find the length of the wire

from the diagram, we can identify two similar triangles

The smaller one and a bigger one

Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal

We can start by getting the height of the tower

we have this as:

8/11 = 28/x

8 * x = 28 * 11

8x = 308

x = 308/8

x = 38.5 ft

So as we can see, the wire represents the hypotenuse of the larger triangle that measures 28 ft base and 38.5 ft height

So we can use the Pythagoras’ theorem to get the hypotenuse

Let us call this g

mathematically according to the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides

thus, we have it that;

g^2 = 38.5^2 + 28^2

g^2 = 2,266.25

g = √2,266.25

g = 47.61 which is approximately 48 ft

Answer:

AC = 10

Step-by-step explanation:

This is a right triangle

use the pythagorean theorem

a² + b² = c²

6² + 8² = c²

36 + 64 = c²

100 = c²

Take the square root of both sides

10 = c

AC = 10

The correct answer is 10 not 12

Answer:

187

Step-by-step explanation:

Fraction to make topping:

1/4 cups of white ; 2/3 cups of brown

Combined = 1/4 + 2/3 = (3 + 8) /12 = 11/12 cups

Fraction of combined used to top muffin = 1/12

Number of muffins that can be topped per combination made :

11/12 ÷ 1/12 ; 11 /12 * 12 / 1 = 11 muffins

Recall :

Each sugar has 11 1/3 cups

For brown sugar :

34 /3 ÷ 2/3 cups

34 /3 * 3 /2 = 17

For white sugar :

34 /3 * 4 /1 = 45.33

However, the highest amount of combined muffin topping for white sugar will be restricted by the number of brown :

Hence,

11 muffins can be topped from each combined mixture ;

Total muffin that can be topped :

17 * 11 = 187 muffins

Answer:

2 inches

Step-by-step explanation:

1/4 = 400

3200/400 = 8

8 x 1/4 = 2

A line on a map need in order to represent 3200 miles would be 2 inches long.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

On a map, 1/4 inch represents 400 miles.

1/4 = 400

3200/400 = 8

8 x 1/4 = 2

Answer:

Kendall's age 6 years ago was 23 years.

Step-by-step explanation:

A system of equations is a set of equations with the same unknowns. A  system of linear equations is a system of equations in which each equation is linear. That is, a system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.

In this case you propose a system, being the variables to solve:

6 years ago, Kelly was younger than Kendall by 6 years. The total age of Kelly and Kendall now is 52 years. So, the system of equations is:

[tex]\left \{ {{x=y-6} \atop {(x+6)+(y+6)=52}} \right.[/tex]

It is solved by the substitution method, which consists of solving one of the unknowns in one of the equations and substituting its value in the following one. The first equation is replaced in the second equation of the system:

(y-6+6)+(y+6)=52

y +(y+6)= 52

y +y+6= 52

2*y + 6=52

2*y= 46

y= 46 ÷ 2

y=23

So, Kendall's age 6 years ago was 23 years.
