a list of measurements in increasing order is 4, 5, 6, 8, 10, and x . if the median of these measurements is ​six sevenths​ times their arithmetic mean, what is the value of x ?

Answer:

anaaaa

Step-by-step explanation:

Average of 5 courses is 72

• In simple words, average is the number which is the representative of the list of the numbers.

• Average of numbers is calculated by the sum of the numbers divided by total numbers.

We are given that

Number of courses took by Adrianna = 4

Average of her course grade = 90

Number of course took by Roberto = 5

We also know that , Both students have the same sum of course grades

Let the average of Roberto be x

Average = Sum / Total Subjects

Sum = Average * Total Subjects

So,

90 * 4 = x * 5

x = 360/5

x = 72

Therefore, average of Roberto is 72

The height of the building is 1122.528 feet.

Angle of elevation:

Angle of elevation means an angle between the horizontal plane and oblique line from the observer's eye to some object above his eye.

Given,

The angle of elevation to the top of a building in New York is 12° from the ground and 1 mile from the base of the building.

Here we need to find the height of the building.

We know that,

The expression for the height of the building is,

h = tanΘ × x

Where the value of

tan Θ = 12°

x = 1 mile

So, When we apply the value on the formula,

The we get,

h = tan 12° x 1

So, apply the value of tan 12 degree,

h = 0.2126 x 1

h = 0.2126 mile

Simplify the above equation using the information

1 mile = 5280 ft.

There are 1176 is the minimum whole number of tiles Tomás needs to completely cover the rectangular floor.

Rectangle:

Rectangle means a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles.

Given,

Tomás wants to tile a rectangular floor with square tiles that measure 12 inches on a side. The floor measures 10 feet 6 inches long by 8 feet 6 inches wide.

Here we need to find if he is able to cut the tiles without waste, what is the minimum whole number of tiles Tomás needs to completely cover the floor.

Here we have to convert the feet into inches for easy calculation,

1 feet = 12 inches

So, the length is ,

l = 120 + 6 = 126 inches

w = 96 + 6 = 112 inches

So, the area of the floor is,

=> l x w

=> 126 x 112

=> 14,112

Here we need to use 12inches square tile,

So,

=> 14112 / 12

=> 1176.

Therefore, there are 1176 tiles are need to cover the floor.

If the equation of the circle is [tex]x^{2} +y^{2}-8x+6=0[/tex] then the center and radius of the circle is (4,0) and [tex]\sqrt{10}[/tex] respectively

Given,

The equation,

[tex]x^{2} +y^{2}-8x+6=0[/tex]

Rearrange the equation

[tex]x^{2} -8x+6+y^{2} =0[/tex]

Add 10 on both sides

[tex]x^{2} -8x+16+y^{2} =10[/tex]

Change to standard form

[tex](x-4)^{2}+(y-0)^{2}=(\sqrt{10})^{2}[/tex]

Standard form of the equation of a circle is

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

Here the r is the radius of the circle and (h,k) is the center

So,

Center = (4,0)

Radius = [tex]\sqrt{10}[/tex]

Darren's monthly payment on car loan is $210.83

Given,

Cost of the car Darren purchased = $11000

The simple interest for the car loan = 3%

Time period of loan = 5 years

We have to find the monthly payment amount:

Simple interest = PRT / 100

Where,

P = Principal amount = $11000

R = Rate of interest = 3%

T = Time period = 5 years

Now,

SI = PRT / 100

SI = (11000 × 3 × 5) / 100

SI = 110 × 3 × 5

SI = 1650

Here, the simple interest for 5 years is $1650

Now,

Total amount to be paid after 5 years = Principal amount + Simple interest

A = P + SI

A = 11000 + 1650

A = 12650

The amount to be paid after 5 years is $12650

Next,

The monthly payment amount:

Number of months in 5 years = 12 × 5 = 60 months

So,

Monthly payment amount = Total amount after 5 years / Total months in 5 years

Monthly payment amount = 12650 / 60 = 210.83

If the number of checks are greater than 25, the Simple Checking plan cost​ less.

We have two checking account plans at Parson's bank.

We have to determine for what number of checks per month will the Simple Checking plan cost​ less.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Let for x number of checks per month the simple checking plan cost less.

For No frills plan -

Charge per check - $0.25

Therefore, for x checks, it will cost - $0.25x

For Simple Checking plan -

Fixed monthly charges - $5

Charges per check - $0.50

Therefore - for x checks - $5 + $0.50x

Now - for Simple Checking plan to cost​ less than No frills plan -

5 + 0.05x < 0.25x

5 < 0.25x - 0.05x

5 < 0.2x

The equation of the line with slope 2/3 and y-intercept at ( 0, - 2) is y = ( 2/3 )x - 2.

The slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible.

We have the slope 2/3 of a line and the y-intercept at ( 0, - 2 ).

Now, we know that

The slope-intercept form of the equation of a line with slope m and y-intercept at the point (0, c) is given by:

y = mx + c

The slope of the line is :

m = 2/3

And, the y-intercept is (0, c) = ( 0, -2)

Hence, the equation of the line in the slope-intercept form will be:

y = mx + c

y = ( 2/3 )x + ( - 2)

y = ( 2/3 )x - 2

We are required to find the equation that can be used to determine the number of pounds of peaches and crumbles that Stephen could have purchased and find the number of crumbles that Stephen purchased if he had 8 pounds of peaches.

Suppose the number of pounds of peaches be x and the number of crumbles be y.
