Answer:

The surface area is 177 square inches

Step-by-step explanation:

Given

[tex]Length = 10[/tex]

[tex]Width = 3[/tex]

[tex]Height = 4\frac{1}{2}[/tex]

Required

The surface area

This is calculated as:

[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]

So, we have:

[tex]Area = 2 * (10* 3+ 10* 4\frac{1}{2}+ 3* 4\frac{1}{2})[/tex]

[tex]Area = 2 * (30+ 45+ 13\frac{1}{2})[/tex]

[tex]Area = 2 * (88\frac{1}{2})[/tex]

[tex]Area = 177[/tex]

The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.

Step-by-step explanation:

The data given is

               Today               Five Years Ago

X`                 81                           85

σ              14.5                        8.5

n                81                          36

The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.

The test statistics that will be used is

Z= x1-x2/ √σ₁²/ n₁ + σ₂²/n₂

Z=  81- 85/ √14.5² /81 + 8.5² /36

z= -4/√210.25/81+ 72.25/36

z= -4/2.1454

z= -1.8644

Answer:

8

Answer: 8

Step-by-step explanation: For absolute values, all values are positive. It is basically the positive inverse of the number.

Answer:

1920 cm³

Step-by-step explanation:

V = w · h · l

V = 8 · 14 · 10

V = 1120 cm³

Now for the smaller one.

V = w · h · l

V = 8 · 10 · 10

V = 800 cm³

1120 cm³ + 800 cm³

1920 cm³

Answer:

1920 cm ^3

Step-by-step explanation:

find the volume of the 2 cuboids seperatly.

bigger one: LXWXH --> 8 X 14 X 10 = 1120

smaller one: LXWXH --> 10X10X8 = 800

add them up

1120 + 800 = 1920 cm

Hope this helps :D

x^3 - 4x + 2 - x^2 + 4x - 4

x^3 - x^2 - 2

Answer:

A

Step-by-step explanation:

[tex]\frac{1}{5} (150x-80y+50-50x-25y+20)[/tex]

step 1 apply the 1/5 to everything that inside of the parenthesis

[tex]\frac{150x}{5} =30x\\\\\frac{-80y}{5} =-16y\\\\\frac{50}{5} =10\\\\\frac{-50x}{5} =-10x\\\\\frac{-25y}{5} =-5y\\\\\frac{20}{5} =4[/tex]

we now have 30x - 16y + 10 - 10x - 5y + 4

Step 2 combine like terms

30x - 10x = 20x

-16y - 5y = - 21y

10 + 4 = 14

we're left with 20x - 21y + 14 Which corresponds with answer choice A

Answer:

20x-21y+14

Step-by-step explanation:

1/5(150x-80y+50-50x-25y+20) is equal to 1/5(150x) + 1/5(-80y) + 1/5(50) + 1/5 (-50x) + 1/5(-25y) + 1/5(20)

So if we simplify, we would have 30x + (-16y) + 10 + (-10x) + (-5y) + 4, or 30x -16y + 10 -10x -5y + 4

When organizing the values by variable, the equation would look like this -

30x - 10x -16y -5y + 10 + 4

Combining like terms will result in 20x -21y + 14.

Hope this helps!

Answer:

2.46212121 miles

-

convert a mile measurement to a foot measurement, multiply the length by the conversion ratio. The length in feet is equal to the miles multiplied by 5,280

The mile, sometimes the international mile to distinguish it from other miles, is the British imperial unit and the US customary unit, both systems are based on the older English unit of length equal to 5,280 feet, or 1,760 yards, and standardised as exactly 1,609.344 metres by international agreement in 1959

To convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.

To convert a distance of 13,000 feet to miles, you can multiply it by the conversion factor of 1 mile divided by 5,280 feet.

We know that

1 mile= 5280 feet

Then we will use the ratio of 1 mile / 5,280 feet, the numerator 1 represents the equivalent distance in miles, and the denominator 5,280 represents the equivalent distance in feet.

So, 13000 feet x 1 mile/ 5280 feet

= 13000/ 5280

= 2.462121212121212 miles

Therefore, to convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.

Step-by-step explanation:

Answer:

13 dancers

Step-by-step explanation:

Since each human has 10 toes, and there are 130 toes,

[tex]\frac{130}{10}=13[/tex]

So, there are 13 people dancing.

I'll do problems 13 and 14 to get you started.

=====================================================

Problem 13

-----------------------

Explanation:

Refer to the diagram below for problem 13. Since BD is a tangent of the circle, this means angle ABD is 90 degrees, and furthermore x+y = 90. This solves to y = 90-x.

If we focus on triangle ABC, then we can add the interior angles and set the sum equal to 180

A+B+C = 180

z+y+y = 180

z+2y = 180

z+2(90-x) = 180 .... plug in y = 90-x

z+180-2x = 180

z-2x = 180-180

z-2x = 0

z = 2x

We'll use this later.

Now move onto triangle ABD. This is a right triangle due to angle ABD being 90 degrees. The acute angles z and 26 are complementary, meaning they add to 90. So,

z+26 = 90

z = 90-26

z = 64

Now plug this into z = 2x and solve for x

z = 2x

64 = 2x

2x = 64

x = 64/2

x = 32

=====================================================

Problem 14

-----------------------

Explanation:

Refer to the image shown below for problem 14. Like before, I've added various labels to it to help find the angle we're after (the red angle x).

Note how I've drawn a dashed line from point A to point D. This splits up quadrilateral ABCD into two triangles ABD and ACD. These triangles can be shown to be congruent using the HL (hypotenuse leg) theorem.

The congruent triangles also implies that angle DBC and angle BCD are the same measure (both are shown in green as the variable y).

Focus on triangle BCD. It has interior angles of: y, y and 62. Add them up, set the sum equal to 180.

y+y+62 = 180

2y+62 = 180

2y = 180-62

2y = 118

y = 118/2

y = 59

As the image attachment mentions, the angles x and y add to 90 degrees. This is because angle ABD is 90 degrees, due to segment BD being tangent to the circle. So x+y = 90 leads to x = 90-y, and therefore,

x = 90-y

x = 90-59

x = 31

Side note: it is not a coincidence that we ended up with half of the value of 62.

Answer:

The correct order is:

a

c

d

b

Step-by-step explanation:

First, let's write 1/x in a convenient way for us:

a) Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.

Now we assume that 1/x is rational (we want to prove that this implies that x will be also rational and because we know that x is irrational assuming that 1/x is rational will lead to an incongruence), then:

c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠ 0. Observe that p is not 0 either, because 1/x is not 0.

Now we know that we can write x as a quotient of two integers, we need to imply that, then the next one is:

d) Observe that x is the quotient of two integers with the denominator nonzero.

And that is the definition of rational, then we end with:

b) Hence x is rational.

Which is what we wanted to get.

c. The one-way ANOVA concerns a single factor with multiple levels and the two ANOVA concerns two factors with also multiple levels.

Step-by-step explanation:

The main difference between one way anova and two way anova is that one way anova has a single independent variable and two way anova has two independent variables.

The dependent variables may vary . They may be one , two or three. They do not affect the method used.

So  one-way ANOVA concerns a single factor and  the two ANOVA concerns two factors.

So the best choice is option c.

Answer:32,200

Step-by-step explanation:

8% is 2576, a simple way to solve for this is to find 1% and that would be 322, then multiply by 100 and you get the total number of people attended, this is not the best method but works in this situation with whole numbers.

Number of people attended the game = 32200

A percentage is a number or ratio that can be expressed as a fraction of 100. If we need to calculate a percentage of a number, divide that number by the whole number and multiply by 100. Percentages therefore mean fractions of 100.  

Given,

Total number of supporter = 2576

Percentage of supporters = 8%

Let total number of attendees = x

the,

8% of x = 2576

8x/100 = 2576

8x = 257600

x = 257600/8

x = 32200

Hence, 32200 people attended the game.

Answer:

Step-by-step explanation:

Volume of a pyramid = 1/3 (l*w*h)

Volume = 1/3(6 * 6 * 9)

Volume = 2 * 6 * 9

Volume = 108 cm³

Volume of cube = s³ ; s = side length

Volume = 4³ = 4 * 4 * 4 = 64 cm³

Number of wax cube = Volume of pyramid / volume of cube

= 108 cm³ / 64 cm³
