By median ,  test scores of 40 students are listed below.  So five number summary is 25, 58,72,81,98

What are median in math?

First we need to sort the data from Smallest to largest data value which is allready sorted

n = 40

Five number summary can be calculated as

Minimum = 25

Q1 can be calculated as

Lower Half of 40 values is 20, so median of 20 values will give us 25th percentile so Median = (20+1)/2 = 10.5th here 10th value is 57 and 11th value is 59 so Q1 = (57+59)/2 = 58

Median = (n+1)/2 = (40+1)/2 = 20.5th value and 20th and 21st value is 72 so median = (72+72)/2 = 72

Upper 20 values after median will provide us Q3 or 75th percentile which can be calculated as 20+(20+1)/2 = 30.5th value so 30th value is 81 and 31st value is also 81. So Q3 = (81+81)/2 = 81

Max = 98

So five number summary is 25, 58,72,81,98

And correct boxplot for this data is A. Boxplot A is correct which shows correct five number summary.

The water pressure on a submerged object is given by P = 64d, then the

a. The answer to the subject of the formula, "d," is d = P/64.

b.  The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet

A function can be defined as an expression, law or rule that shows the relationship between two variables.

These variables are namely;

Given the role as;

P = 64d

Where;

P stands for pounds per square foot of pressure.

d represents the object's depth in feet.

Let's now make the variable "d" the focus of the formula.

The coefficient of the variable "d," which is 64, is used to divide both sides of the equation. So that the variable can stand on its own, this is done.

(a) We get,

P/64 = 64d/64

d = P/ 64

(b) P equals 672 pounds per square foot if there is pressure.

When the variable's value is substituted into the formula, we get;

d = P/64

Then,

d = 672/64

Discover the quotient,

d = 10. 5 ft.

The value is 10.5 feet .

Therefore,

a. The answer to the subject of the formula, "d," is d = P/64.

b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet.

Jane, Alan, and Ravi sent a total of 146 text messages over their cell phones during weekend, Ravi sent 8 fewer messages than Jane. Alan sent 4 times as many messages as Ravi. So as per question data,

Jane sent= 31 messages

Ravi sent= x-8= 31-8 = 23 messages

Alan sent= 4(x-8) = 92 messages

The best way to solve an expression is from left to right if all the operations are the same (for instance, only addition, only subtraction, only multiplication, or only division). However, we must adhere to the order of operations for expressions including several operations.

The rule that dictates how to solve an expression involving numerous operations is known as the order of operations.

PEMDAS can help you remember that sequence. In PEMDAS, each letter denotes a mathematical operation.

Let, Jane sent x number of messages

Then, Ravi sent x-8 number of messages

and, Alan sent 4(x-8) number of messages

Total number of messages by them = 146

now,

x+(x-8)+4(x-8)=146

6x-40=146

x=31

so, Jane sent= 31 messages

Ravi sent= x-8= 31-8 = 23

Alan sent= 4(x-8) = 92

To find the x-intercept, simply but y=0 in the equation given and solve for x

That is;

3x - 4y = 12

3x - 4(0) = 12

3x = 12

Divide both-side of the equation by 3

x= 4

The x-intercept is;

(4, 0)

To find the y-intercept, simply put y=0 in the equation given and then solve for y

That is;

If a package of 5 pairs of insulated gloves costs $28.955,then the unit price of the pairs of gloves is $5.791

A package of 5 pairs of insulated gloves costs ​$28.955

The price of 5  pairs of insulated gloves = $28.955

Here we have to use the unitary method

The price of 1 pair of insulated gloves = The price of 5  pairs of insulated gloves / 5

Substitute the values in the equation and divide it

The price of 1 pair of insulated gloves = 28.955/5

= $5.791

Answer:

  y = x³ -2x² -13x -10

Step-by-step explanation:

You want a polynomial with x-intercepts -2, -1, and 5, and a y-intercept of -10.

A polynomial with zero x = p will have a factor of (x -p). The three given zeros mean factors of the desired polynomial will be ...

  p(x) = (x -(-2))(x -(-1))(x -5) = (x +2)(x +1)(x -5)

Expanding this gives ...

  p(x) = (x +2)(x² -4x -5) = x³ -2x² -13x -10

This polynomial has a constant of -10, which will be its y-intercept. No additional scaling is needed.

The polynomial function is ...

Given:

Cost of Truck = $16000

Down payment amount = $3000

EMI = $250

Duration of EMI = 60 Months

Required:

a) Total amount financed

b) Total finance charge paid at the end of 60 months

Explanation:

Total cost of Truck = $16000

The total amount taken from other source = Total Amount - Down payment

=$16000-$3000

=$13000

EMI = $ 250

Total amount paid at the end of 60 months = $15000

The total amount financed = Actual price -Down payment

=$16,000- $3000

=$13000

a) Total amount financed =3$18000

The total finance charged = Actual price - amount paid monthly for 60 months.

=$16000-$15000

=$1000

b)The total finance charged =1$20

Hence the total amount finance is 13000 dollar.

The total finance charged is 1000 dollar.00

An arithmetic progression is a sequence of numbers in which the difference between any two consecutive terms in the sequence is constant

The given parameters are;

Numbers circled with red circles by Caitlin = All even numbers between 1 and 2022

Numbers Nicole circles using yellow = Numbers that are multiples of 5

Required; The number of numbers that are circled with one colour only

Solution; The even numbers are numbers that are a multiple of 2

The number of even numbers between 1 and 2022 are found using arithmetic progression formula as follows;

[tex] a_{n} = a_{1} + (n - 1)\cdot d[/tex]

Where;

[tex]a_{1}[/tex] = The first term = 2 (First even number)

d = The common difference = 2

n = The number of terms

Given that 2022 is an even number, we have;

[tex] a_{n} = 2022 = 2 + (n - 1)\cdot 2[/tex]

Which gives;

[tex] \displaystyle {n = \frac{(2022 - 2)}{2} + 1 = 1011} [/tex]

We note that 10 is the lowest common multiple of 2 and 5, which gives;

Multiples of 10 have two colors, therefore, the numbers that have only one color is given by the difference between the number of even numbers and the number of multiples of 10 as follows;

The number of multiples of 10 are;

[tex] \displaystyle {n = \frac{(2020 - 10)}{10} + 1 = 202} [/tex]
