a final exam in math 160 has a mean of 73 with standard deviation 7.2. if 22 students are randomly selected, find the probability that the sample mean of their test scores is less than 75

Answers

Answer 1

The probability is that the mean of their test scores is less than 70.

What is probability?

A probability is a number that reflects tha chance of particular event will occur.

Sol-

As per the question given-

Mean = 73

Standard daviation=7.2

Number of students randomly selected =22

Let's take n number for experiment of outcomes.

The number of favorable outcomes can be denoted by x.

The formula to calculate the probability is -

probability = favorable

Outcomes/total outcomes =x/n

The number of standard daviation form the mean is called z.

Z = (x-¥)/€

Z=(75-73)(7.2/√22)

Z= -37.0582965

P(z<-37.05)

= 37.05

There for the probability is 37.05.

a₁ = 4; a = (a)²-3 (n ≥2) list the first five terms

Answers

The first five terms of the given sequence are 4, 1, 6, 13, 22

We can solve this problem by following a few steps.

The formula to find the next four terms is, a =  (n)²- 3, (n ≥2) as per the question.

Where n is the sequence of the number ( n = 2, 3, 4, 5, 6, etc. )

So, for the 2nd term A₂ = 2² - 3 = 4 - 3 = 1  [As n = 2 for the second term ]

Similarly, for the 3rd term A₃ = 3² - 3 = 9 - 3 = 6  [ As n = 3 for the third term ] ,

for the 4th term A₄ = 4² - 3 = 16 - 3 = 13  [ As n = 4 for the second term ] ,

for the 5th term A₂ = 5² - 3 = 25 - 3 = 22  [As n = 5 for the second term ]

Now, we can conclude that the first five terms of the given sequence are 4, 1, 6, 13, 22

The coldest recorded temperature in the United States is

How much higher is the warmest recorded temperature than the coldest recorded temperature?

Answers

The warmest recorded temperature is 214°F higher than the coldest temperature.

Since the sign of the two numbers are same, their final values will be added and the result will have the same signs as the two numbers (or the one with the greater absolute value). This is called the multiplicative property.

Expression for difference between the two temperatures is,

= 134−(−80)

By applying the multiplicative property of negative sign, we get

=134+80

= 214°F

Therefore, we conclude that the warmest recorded temperature is 214°F  higher than the coldest temperature.

i have a derivative question about tangent lines, pic included

Answers

To find the horizontal tangent line, we have to conduct the first derivative test. The first derivative test sets the derivative of the function equal to 0.

Let's start out with finding the derivative of the function:

It seems like we will have to use Quotient Rule.

[tex]f^{\prime}(x)=\frac{(x^2-7x+1)(x+9)^{\prime}+(x^2-7x+1)^{\prime}(x+9)}{(x^2-7x+1)^2}[/tex]

Now we can use basic derivative rules and properties to find the final derivative:

[tex]f^{\prime}(x)=\frac{(x^2-7x+1)+(2x-7)(x+9)}{(x^2-7x+1)^2}[/tex]

Setting the derivative equal to 0, we can begin the first derivative test:

[tex]0=\frac{(x^{2}-7x+1)+(2x-7)(x+9)}{(x^{2}-7x+1)^{2}}[/tex]

We can simplify the derivative before solving (expand and combine like terms):

[tex]0=\frac{-(x^2+18x-64)}{(x^2-7x+1)^2}[/tex]

From here, we need to determine our values of x that will make the derivative equal to 0 or undefined. In this case, since we are not trying to find relative maxima or minima, we just need to find where the entire derivative is equal to 0. We can simply just graph the numerator and find its roots:

We can see that the values of x will be -21.0416 and 3.04159 will be the values that make the derivative equal to 0.

Also recall what the derivative is. The derivative is the slope of the tangent line. In order to find the horizontal tangent line, we know that horizontal tangent lines' slope is equal to 0.

Therefore, we can use either value of x to now find our equation.

Recall what the point-slope form of a line is:

[tex]y-y_1=m(x-x_1)[/tex]

Since we know that the derivative slope must equal 0, then we know that m = 0. We now need to find a point (x, y). Substitute one of the x values into the original equation to find an actual point on the function (remember not to round intermediate values on your calculator!):

[tex]\begin{gathered} f(3.04159)=\frac{3.04159+9}{3.04159^2-7(3.04159)+1} \\ f(3.04159)=-1.09074 \end{gathered}[/tex]

Now we have a point (x, y) (I will put it in the actual radical form here):

[tex]\bigg(\sqrt{145}-9,\frac{-2\sqrt{145}}{45}-\frac{5}{9}\bigg)[/tex]

Substitute our variables into point-slope form:

[tex]y-\bigg(\frac{-2\sqrt{145}}{45}-\frac{5}{9}\bigg)=0\bigg(x-(\sqrt{145}-9)\bigg)[/tex]

Simplify and rewrite to obtain our final answer:

[tex]y=\frac{2\sqrt{145}}{45}+\frac{5}{9}[/tex]

When you sold your shares, your account showed $4680.00 ($72.00 × 65 shares), for a total gain of $357.50 ($4680.00 – $4322.50). What percentage gain did you experience?

Answers

The percentage that 7.64% gain experienced you if sold your shares, your account showed $4680 for a total gain of $357.50.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Saima obtained a score of 57% on her exam, that corresponds to 67 out of 100. It is expressed as 57/100 in fractional form and as 57:100 in ratio form.

Given that when you sold your shares, your account showed $4680.00 ($72.00 × 65 shares)

For a total gain of $357.50 ($4680.00 – $4322.50).

Let the percentage gain you experienced be x %

As per the given data, the solution would be as:

⇒ x% of 357.50 = 4680.00

x%  is expressed as x/100 in fractional form

⇒ (x/100)(357.50) = 4680.00

⇒ x = 357.50/4680.00 × 100

⇒ x = 7.64%

The image of the point B ( − 4 , 6 ) under 270° clockwise rotation is point (-6 , -4).

A transformation that revolves a figure around a point is called a rotation. The rotational center is where we refer to it. The shape and dimensions of a figure remain the same while facing in a different direction. You can rotate a figure either clockwise or counterclockwise.

Under a rotation about the origin, the point A ( 5 , − 1 ) is mapped to the point A ' ( 1 , 5 ) is a -

The transformation of △FGH to △F’G’H is (B) the reflection across the x-axis.

What do we mean by reflection across the x-axis?The x-coordinate remains constant when a point is reflected across the x-axis, but the y-coordinate is assumed to be the additive inverse. Point (x, y) is reflected across the x-axis as (x, -y).A graph will appear to be inverted or on the other side of an axis, such as the x-axis, when it is reflected along that axis.If you look closer, you'll notice that it's symmetrical, meaning that each point is equally spaced from the axis of reflection and the axis of its reflection.As a result, if you reflect a point (x, y) along the x-axis, its x abscissa will remain the same but its y ordinates will negate. So (x,y) becomes (x, -y)

So, the difference between the vertices of triangle FGH and F’G’H is the y-coordinates of the F’G’H triangle are inverse of the y-coordinates of the FGH triangle.

And as we know that in reflection across x-axis the x-coordinate remains constant when a point is reflected across the x-axis, but the y-coordinate is assumed to be the additive inverse.

An equation of the line containing the given point and parallel to the given line is y = 2x - 19.

The condition for two parallel lines.

In Mathematics, two (2) lines are considered to be parallel if their slopes are the same (equal) and they've different y-intercepts. This ultimately implies that, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m is the slope.

Mathematically, the point-slope form of a line is given by this equation:

y - y₁ = m(x - x₁)

Where:

x and y are the points.m represents the slope.

Given the following equation:

2x - 56 = 3     ⇒ m₁ = 2

Therefore, m₁ = m₂ = 2.

At point (8, -3), we have:

y - y₁ = m(x - x₁)

y - (-3) = 2(x - 8)

y + 3 = 2(x - 8)

y + 3 = 2x - 16

You purchase 5 tickets to a football game from TicketMaster. In addition to the cost per ticket, the agency charges a convenience charge of $2.50 per ticket. You also choose to pay for rush delivery, which costs $15. The total cost of your order is $352.50. What is the price per ticket before the convenience charge?

Answers

The price per ticket, excluding the convenience charge, is  $65.

How to solve for the privce per ticket

the rush delivery is given as $15.

The total cost of the tickets is said to be put at $352.50

Then the value that we would have for the the 5 tickets wpould be 352.50 - 15 = $337.50.

There is the convenience charge of $2.50 per ticket. This charge is excluded from the convenience charge that is to be paid.

Hence you would have to make the payment of

337.50 - 5*2.50

= 325.

Next we are to solve for the price of the ticket whioch is independent of the convenience charge

= 325 / 5

= $65

Hence the price per ticket is given as 65 dollars

The constant variation of hight(y) to seconds(x) is 3y/2x.

What is the constant variation?The quantity that connects two variables that are directly or inversely proportional to one another is known as the constant of variation. By dividing the y-coordinate by the x-coordinate, we can find k when given any point because it is constant (the same for every point). For instance, the constant of variation is k = = 3 if y varies directly as x and y = 6 when x = 2.

So, let the second be 'x' and the height is 'y'.

At 4 seconds the wavelength is 6 ft high.

Constant variation:

y/x = 6/4 = 3/23y/2x

So,

x = 4, x = 8, x = 12y = 6, y = 12, x = 18

We are asked to determine the equation of a line that passes through the point (-3, -1) and has a slope 2/5. To do that we will use the point-slope form of a line equation:

[tex]y-y_0=m(x-x_0)[/tex]

Where:

[tex]\begin{gathered} (x_0,y_0)=\text{ point on the line} \\ m=\text{ slope} \end{gathered}[/tex]

Now, we plug in the values:

[tex]y-(-1)=\frac{2}{5}(x-(-3))[/tex]

Simplifying we get:

[tex]y+1=\frac{2}{5}(x+3)[/tex]

Now, we apply the distributive law:

[tex]y+1=\frac{2}{5}x+\frac{6}{5}[/tex]

Now, we subtract 1 from both sides:

[tex]\begin{gathered} y=\frac{2}{5}x+\frac{6}{5}-1 \\ \\ y=\frac{2}{5}x+\frac{1}{5} \end{gathered}[/tex]

and thus we get the equation of the line.

The Life time in hours of a certain aircraft has the normal distribution with mean 80, Standard devation 16. What is the probability that the aircraft Will last 100 hours

Answers

1.25 is the probability that the aircraft Will last 100 hours.

What is probability?

The area of mathematics described as probability concerns with numerical representations of the likelihood that an event will occur or that an assertion is correct. An event's probability is a number between 0 and 1, where, roughly speaking, 0 indicates the event's impossibility and 1 represents certainty. 

Given Data

Mean = 80

Standard deviation = 16

P( x < 100)

P( x < 100) = P( Z< [tex]\frac{x- mean}{standard deviation}[/tex])

P(x<100 ) = P( Z < [tex]\frac{100-80}{16}[/tex])

P(x< 100) = P(Z< [tex]\frac{20}{16}[/tex])

P(x < 100) = 1.25

1.25 is the probability that the aircraft Will last 100 hours.
