What is the volume of a box with a height of 3/2 inches, a length of 7/2 inches, and a width of 5/2 inches.

Answer:

Step-by-step explanation:

Only a straight line can be formed at the intersection of a plane with another plane. The faces of a cube are planes, so a 2-dimensional (planar) cross section of a cube cannot be a curve. It cannot be an ellipse or circle.

The intersection of a plane with a cube can be a polygon with 3, 4, 5, or 6 sides. That is, the 2-D cross section of a cube can be ...

Answer:

Step-by-step explanation:

Let x be a random variable representing the life of a Brand Q car battery. With the mean and standard deviation given, then the Empirical Rule says the that

1) About 68% of the x values lie between 1 standard deviation below and above the mean.

2) About 95% of the x values lie between 2 standard deviations below and above the mean.

3) About 99.7% of the x values lie between 3 standard deviations below and above the mean.

From the information given,

mean = 36 months

Standard deviation = 4 months

Therefore,

1) 68% of all batteries will have a life between 36 - 4 = 32 months and 36 + 4 = 40 months.

2) 95% of all batteries will have a life between 36 - 2(4) = 28 months and 36 + 2(4) = 44 months.

Answer:

No, it’s 7.50

Step-by-step explanation:

The discounted price is 7.5, but according to question the discounted price is $10. Therefore given statement is wrong.

Percentage is a measurement to find value of given number out of hundred.

Given that,

Cost price of one shirt = $10.

Also, Shopkeeper marks up 50 % on shirts.

Marked up price = 10 x 50% = 10 x 50 / 100 = $15

Since, shopkeeper gives discount as put the shirts on sale for 50% off.

So the price after giving discount = 15 x 50 / 100 = 7.5

The discounted price of shirt is 7.5.

Hence, the given statement that is discount price is $10 is incorrect.

Answer: Mode

Step-by-step explanation:

There are three main measures of central tendency: the mode, the median and the mean.

Since the boy has to purchase the brand which is most liked by children, he is using mode.

The mode is the most commonly occurring value in a distribution. That is, the value that occurs most frequently in a set of observations

Answer:

No

Step-by-step explanation:

If segment AB is tangent to the circle, then angle CBA will be a right angle, making triangle ABC a right triangle. If triangle ABC is a right triangle, it's sides will fit the Pythagorean theorem...

(leg)^2 + (leg)^2 = (hypotenuse)^2

Does 8^2 + 16^2 = 19^2 ?

64 + 256 does not equal 361!

Triangle ABC is NOT a right triangle, so segment AB is not tangent to the circle.

Answer:

0.7048

Step-by-step explanation:

∫₂⁴ 1 / (x − 1)² dx

n = 4, so we divide the interval into 4 regions.  The width of the regions is:

(4 − 2) / 4 = 0.5

So the intervals are (2, 2.5), (2.5, 3), (3, 3.5) and (3.5, 4).

Evaluate f(x) at the ends of each interval.

f(2) = 1

f(2.5) = 4/9

f(3) = 1/4

f(3.5) = 4/25

f(4) = 1/9

Find the area of each trapezoid:

A₁ = ½ (2.5 − 2) (1 + 4/9) = 13/36

A₂ = ½ (3 − 2.5) (4/9 + 1/4) = 25/144

A₃ = ½ (3.5 − 3) (1/4 + 4/25) = 41/400

A₄ = ½ (4 − 3.5) (4/25 + 1/9) = 61/900

So the total approximate area is:

A = 0.705

Closest answer is 0.7048.

The value of expression is,

⇒ 0.7048

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

⇒ ∫₂⁴ 1 / (x − 1)² dx

Now, For n = 4, we divide the interval into 4 regions.  

Hence, The width of the regions is:

= (4 − 2) / 4

= 0.5

Thus, the intervals are,

⇒ (2, 2.5), (2.5, 3), (3, 3.5) and (3.5, 4).

Thus, We can evaluate f(x) at the ends of each interval as,

f(2) = 1

f(2.5) = 4/9

f(3) = 1/4

f(3.5) = 4/25

f(4) = 1/9

Hence, the area of each trapezoid are,

A₁ = 1/2 (2.5 − 2) (1 + 4/9) = 13/36

A₂ = 1/2 (3 − 2.5) (4/9 + 1/4) = 25/144

A₃ = 1/2 (3.5 − 3) (1/4 + 4/25) = 41/400

A₄ = 1/2 (4 − 3.5) (4/25 + 1/9) = 61/900

Therefore, the total approximate area is:

A = A₁ + A₂ + A₃ + A₄

A = 0.7048

4949 square units.

Step-by-step explanation: dk

Scale factors are used to enlarge or reduce the size of a shape

The area of polygon w is 49 square units

The area of polygon v is given as:

[tex]v =1[/tex]

The scale factor of the sides of polygon v, that forms polygon w is given as:

[tex]k=7[/tex]

The area of polygon w is then calculated as:

[tex]w =v\times k^2[/tex]

So, we have:

[tex]w =1\times 7^2[/tex]

Evaluate the exponents

[tex]w =1\times 49[/tex]

I assume this is the intersection of two lines, i.e. -1/2y is (-1/2)y.  Please tell me if it's really -1/(2y).

Multiplying both sides by -2

y = - x - 10

The other equation is

y = 2x + 2

We can equate them to find the meet

y = - x - 10 = 2x + 2

-3x = 12

x = -4

y = 2x + 2 = -6

Answer:

The result for the equation is [tex]x = -8[/tex] .

Step-by-step explanation:

-Subtract [tex]x[/tex] from [tex]0.75x[/tex] :

[tex]0.75x -0.5-x =x -x+1.5[/tex]

[tex]-0.25x -0.5 = 1.5[/tex]

-Add both sides by 0.5 :

[tex]-0.25x -0.5 +0.5 =1.5 +0.5[/tex]

[tex]-0.25x = 2[/tex]

-Divide both sides by 0.25 :

[tex]\frac{-0.25x}{-0.25} =\frac{2}{-0.25}[/tex]

Answer: x = 0, y = 7

-x+y=7

add x to both sides

y=x+7

plug this in for y in the other equation

6x-(x+7)=-7​

simplify

6x-x-7=-7

simplify

5x-7=-7

add 7 to both sides

5x=0

divide both sides by 5

x=0

plug in to one of the equations to find y

-(0)+y=7

y=7

Therefore, x=0 and y=7.

Answer:

2/26

Step-by-step explanation:

The total number of students = 26 students

Number of students that like maths = 15 students

Number of students that like English = 13 students

Number of students that does not like English or maths = 9

We have to find the number of students that likes both Maths and English.

Therefore,

Let x be the number of student that like both Maths and English subjects

15 - x + x + 13 - x + 9 = 26

-x + 37 = 26

-x = -11

x = 11

Number of student that offer english but not math

 Number of students that like English but not Maths   = Number of Students that like English - Number of students that like English and Maths

= 13 - 11                                                 = 2 

Therefore, probability that a student chosen at random like English but not Maths.    

Probability = Number of events ÷ Number of possible outcomes  

Number of events = Number of students that like English but not Maths= 2

Number of Possible outcomes = Total number of students = 26 

The probability that a student chosen at random like English but not Maths.

= 2/26

Answer:

Step-by-step explanation:

a hexagonal prism is made up of two bases that are hexagons and six faces that are rectangles.

Lateral surface area, LA = Perimeter × height

Perimeter = number of sides × length of each side

Perimeter, P = 6 × 10 = 60

LA = 60 × 12 = 720 units squared

Area of each base, B = 1/2a × perimeter

Where

a = apotherm

We would determine the length of the apotherm of each base of the prism by applying the formula,

a = s/[2tan(180/n)]

Where

s = length of each side = 10

n = 6 sides

a = 10/[2tan(180/6) = 10/[2tan30)

a = 8.66

B = 1/2 × 8.66 × 60 = 259.8

Total surface area = LA + 2B

Total surface area = 720 + 2 × 259.8 = 1239.6 units squared

Answer:

104800

Step-by-step explanation:

The revenue is the profit times the number of computers sold

R(t) = P(t) *  N(t)

              = (13t^2-25t+600) * ( 5t+106)

We want the revenue in 2010 which is 5 years from 2005  so t = 5

R(5) = (13* 5^2-25*5+600) * ( 5*5+106)

       = (13 *25 - 125+600)*(25+106)

      = (325-125+600) * ( 25+106)

        (325-125+600) * ( 25+106)

         800* 131

          104800

Answer:

104,800

Step-by-step explanation:

2010 is 5 years after 2005, so t = 5

The number of computers sold:

N(5)=5(5)+106 = 131

Price per computer:

P(t)=13(5²)-25(5)+600 = 800

Answer:

70,000

Step-by-step explanation:

5 always rounds UP to the nearest whole number, therefore, 70,000.

65321 rounded to nearest ten thousand's place becomes 70000.

An easy way of rounding numbers to ten thousand's place we'll understand by an example.

65321 have to rounded to ten thousand's place which is either 60000 or 70000.Here the given number is more closer to 70000 than 60000 so therefore 65321 rounded to the nearest ten thousand is 70000.

According to the given question

We have 65321 and we have to round it to the nearest ten thousand.

To round a number nearest to ten thousand first we'll check the digit of thousand's place which is 5 we'll add 1 to it make all the digits after that 0.

Now this becomes 66000.

Now we'll check for the digit in ten thousand's place which is 6 we'll add 1 to it and make the rest of the digits 0 hence it becomes 70000.
