Answer:

The value is  [tex]P(X > 500 ) = 0.011942[/tex]

Step-by-step explanation:

From the question we are told that

       The mean is  [tex]\mu = 430[/tex]

       The standard deviation is  [tex]\sigma = 120[/tex]

       The sample size is  n  =  15

Generally  the probability that the sample mean is above 500

Gnerally the standard error of mean is mathematically represented as

             [tex]s = \frac{\sigma }{ \sqrt{n} }[/tex]

=>          [tex]s = \frac{ 120 }{ \sqrt{15} }[/tex]

=>           [tex]s = 30.984[/tex]

Generally  the probability that the sample mean is above 500

     [tex]P(X > 500 ) = P( \frac{X - \mu }{\sigma_x} > \frac{500 - 430 }{ 30.984 } )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

       [tex]P(X > 500 ) = P( Z > 2.259 )[/tex]

=>     [tex]P(X > 500 ) = P( Z > 2.259 )[/tex]

From the z table  the area under the normal curve to the right  corresponding to  2.259  is

          [tex]P( Z > 2.259 ) = 0.011942[/tex]

=>       [tex]P(X > 500 ) = 0.011942[/tex]

Answer:

A

Step-by-step explanation:

We know it cant be -6 as that would be a range and since the circle on the end is hallow it wont be less or equal to rather just less than and the since the next one is 2 and its solid circle it has to be less than or equal too

Answer:

A. -9 < x ≤ -2

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the graph, the line's x-values span from -9 to 2. Since -9 is an open dot, it is exclusive in the domain. Since 2 is a closed dot, it is inclusive in the domain:

(-9, 2] or -9 < x ≤ -2

Answer:

1/2

Step-by-step explanation:

4/9 is .444

1/2 is .5

1/3 is .3333

Answer:

126807 people

Step-by-step explanation:

Given;

P= Poe^ht

Where;

P= population at time t

Po= population at the beginning

h= growth constant

t= time

1998- 2008 is ten years.

110429= 100,000e^10h

1.1 = e^10h

ln(1.1) = lne^10h

0.095 = 10h

h= 0.0095

In 2023, t = 25 years

P= 100,000e^(0.0095 × 25)

P= 126807 people

Answer: (-6, - 6)

Step-by-step explanation:

Here we have two transformations, and the first step will be to explain those transformations:

Reflection over the y-axis.

For a function f(x), the reflection over the y-axis is written as:

g(x) = f(-x)

Then if we initially had a point (x, y), the transformed point will be (-x, y).

Vertical translation.

We can define a vertical translation of N units as:

g(x) = f(x) + N

if N > 0, the translation is up.

If N < 0, the translation is down.

Then if we start with a point (x, y), the transformed point will be (x, y + N)

In the case of this problem we have g(x) = f(-x) - 3

This means that N = -3

Then if we initially had the vertex at the point (6, - 3)

The transformed point will be: changing the sign of the x-component and subtracting 3 in the y-component, then the transformed vertex point is:

(-6, -3 - 3) = (-6, - 6)

The vertex of the resulting  parabola will be (-6, -6)

Given the function y= f(x), plotted on a graph and the vertex of the resulting

parabola is (6, -3), if this coordinate is reflected over the y-axis, the reflection rule will be:

To get the corresponding function [tex]g(x) = f(x) - 3\\[/tex]

[tex]g(x) = [(-6, -3) - 3]\\g(x) = (-6, -3-3)\\g(x) =(-6, -6)[/tex]

Hence the vertex of the resulting  parabola will be (-6, -6)

Answer:

D

Step-by-step explanation:

The coordinates of Y will be (7, 2)

Option B is the correct answer.

It is the process of moving a shape to its left, right, up, or down.

The translated and the original shapes are congruent.

We have,

Triangle XYZ.

Vertices:

X(-4, 3), Y(-3, -2), and Z(-7, -4).

The coordinates of Y = (-3, -2)

If the triangle is rotated 270 degrees clockwise, the coordinates of
Y = (-3, -2) will turn to Y = (3, -2).

Translated 9 units to the right.

Y = (3 + 9, -2 + 9)

Y = (12, 7)

Translated 5 units down:

Y = (12 - 5, 7 - 5)

Y = (7, 2)

Thus,

The coordinates of Y will be (7, 2)

Option B is the correct answer.

Answer:

[tex]Probability = \frac{1}{5}[/tex] or [tex]Probability = 0.2[/tex]

Step-by-step explanation:

Given

[tex]Black = 25[/tex]

[tex]White = 35[/tex]

[tex]Red = 40[/tex]

Required

Determine the probability of selecting Black and Red

First, we need to calculate the number of red and black balls

The probability is calculated as thus:

[tex]Probability = P(Black\ and \ Red) \ or\ P(Red\ and \ Black)[/tex]

Convert to mathematical expressions

[tex]Probability = [P(Black) *P(Red)] + [P(Red) *P(Black)][/tex]

Solve for each probaility;

[tex]P(Black) = \frac{Black}{Total} = \frac{25}{100}[/tex]

[tex]P(Red) = \frac{Red}{Total} = \frac{40}{100}[/tex]

So, we have:

[tex]Probability = [P(Black) *P(Red)] + [P(Red) *P(Black)][/tex][tex]Probability = [\frac{25}{100} *\frac{40}{100}] + [\frac{40}{100} *\frac{25}{100}][/tex]

[tex]Probability = [\frac{1000}{10000}] + [\frac{1000}{10000}][/tex]

[tex]Probability = [\frac{1}{10}] + [\frac{1}{10}][/tex]

[tex]Probability = \frac{1+1}{10}[/tex]

[tex]Probability = \frac{2}{10}[/tex]

[tex]Probability = \frac{1}{5}[/tex]

or

[tex]Probability = 0.2[/tex]

Step-by-step explanation:

1st) Distribute 8 with x and 8 with -1 which will give you

8x-8=5x-35

2nd) Use opposite operation and add 8 both sides

8x-8=5x-35

+8 +8

---------------

8x=5x-27

3rd) subtract 5x from both sides

8x=5x-27

-5x= -5x

E: The study was not comparative—only one treatment was used.

Step-by-step explanation:

Well-designed experiments should involve comparisons of at least two treatment groups, one of which could be a control group.

A well-designed experiment investigates design features that achieve the research to rule out sources of variation as reasons for the observed relationship between both the independent variable(s) and the predictor variables.

Therefore, the final answer is "Option E".
