Answer:

Step-by-step explanation:

Answer:

a) 2.66

b) 9

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

part A: what is the standard deviation of the sampling distribution of x hat? show your work.

We have that [tex]\sigma = 8.4, n = 10[/tex]. So

[tex]s = \frac{\sigma}{\sqrt{n}} = \frac{8.4}{\sqrt{10}} = 2.66[/tex]

PartB: what does the sample size need to be if you want the standard deviation of the sampling distribution of x hat to be 2.8?

This is n when [tex]s = 2.8[/tex]. So

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

[tex]2.8 = \frac{8.4}{\sqrt{n}}[/tex]

[tex]2.8\sqrt{n} = 8.4[/tex]

[tex]\sqrt{n} = \frac{8.4}{2.8}[/tex]

[tex]\sqrt{n} = 3[/tex]

[tex](\sqrt{n})^2 = 3^2[/tex]

[tex]n = 9[/tex]

the correct answer is,

[tex]x = \frac{121}{25} [/tex]

if you want me to solve without the parentheses then the answer would be,

[tex]x = \frac{1609}{100} [/tex]

Answer:

62.0496 yards separate the first platform from the second platform

Step-by-step explanation:

We have to make the conversion of both units to yards.

Each feet has 12 inches.

Each inch is 0.0278 yards.

The first platform of the Eiffel Tower is 2,280 inches above the ground.

So

2280*0.0278 = 63.384 yards above the ground.

The second platform is 376 feet above the ground.

So

376*12*0.0278 = 125.4336 yards above the ground

How many yards separate the first platform from the second platform?​

125.4336 - 63.384 = 62.0496

62.0496 yards separate the first platform from the second platform

I believe it is the first third and fourth options, I am not entirely sure for I mostly guessed on them, but they make the most sense when looking at the graph.

Step-by-step explanation:

It can be deduced that the graph of function f and g compare as:

A function in mathematics simply means the relation between a set of inputs and a set of permissible outputs.

In this case, the graph of both functions have a vertical asymptote of x = 0. This is because the divisor equals to zero for a value of x.

In the case above about Samuel, we can say that Samuel's calculator has display option A;  2.5 E (- 13)

The function was 5 EE (-) 9 divided by 2 EE 4

5 EE (-) 9/ 2 EE 4

We know that, E implies 10 to rise to power.

So, the equation above is Converted from scientific notation into standard form;

= 5 EE (-) 9/ 2 EE 4

= 5/2  x 10 ⁻⁹⁻⁴

=2.5 x 10⁻¹³

Therefore, In the case above about Samuel, we can say that Samuel's calculator has display option A;  2.5 E (- 13)

Answer:

64 pints in 8 gallons :))

Answer:

x= -1

y= -8

Step-by-step explanation:

Solve for y in 8x + y = -16

y = -16 - 8x

Substitute y = -16 - 8x into -3x + y = -5

-11x - 16 = -5

Solve for x in -11x - 16 = -5

x = -1

Substitute x = -1 into y = -16 - 8x

y = -8

Therefore,

x= -1

y= -8

Answer:

(-1, -8)

Step-by-step explanation:

SUBSTITUTION METHOD:

Solve for y in the first equation by subtracting 8x from both sides.

Substitute this value for y into the second equation.

Remove the parentheses and simplify.

Combine like terms.

Add 16 both sides of the equation.

Divide both sides of the equation by -11.

Substitute this value for x into either equation (I'm using the first equation).

Multiply and simplify.

Add 8 to both sides of the equation.

ELIMINATION METHOD:

Subtract the second equation from the first equation to "cancel" the y-variable.

Divide both sides of the equation by 11.

Substitute this value for x into either equation (I'm using the second equation).

Multiply and simplify.

Subtract 3 from both sides of the equation.

The solution to this system of equations is (-1, -8).

Answer:

any equation that have the slope of -2

A line which is perpendicular to the line x – 2y = -14 will have a slope of -2

The slope of a line is a measure of its steepness.

Given an equation of a line  x – 2y = -14

We know that, the slope of a line perpendicular to another line will have a slope of its negative reciprocal.

Therefore, slope of the line perpendicular to the line x – 2y = -14  will be -2

Hence, equation of the line perpendicular to the line x – 2y = -14 will have a slope of -2

slope -intercept form y=mx+c

The equation of the straight line

                                 y = 0x +13

Step-by-step explanation:

Step(i):-

Given that the points

           (11 ,13) and (7,13)

The slope of the line

    [tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{13-13}{7-11} = \frac{0}{-4} =0[/tex]

Step(ii):-

Equation of the straight line passing through the point (11,13) and slope m=0

y - y₁ = m( x-x₁)

y - 13 =0(x-11)

y-13 =0

y =13

slope -intercept form y=mx+c

y = 0x +13

Answer:

Step-by-step explanation:

Simplifying

25m + 22 = 9m

Reorder the terms:

22 + 25m = 9m

Solving

22 + 25m = 9m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-9m' to each side of the equation.

22 + 25m + -9m = 9m + -9m

Combine like terms: 25m + -9m = 16m

22 + 16m = 9m + -9m

Combine like terms: 9m + -9m = 0

22 + 16m = 0

Add '-22' to each side of the equation.

22 + -22 + 16m = 0 + -22

Combine like terms: 22 + -22 = 0

0 + 16m = 0 + -22

16m = 0 + -22

Combine like terms: 0 + -22 = -22

16m = -22

Divide each side by '16'.

m = -1.375

Simplifying

m = -1.375
