Step-by-step explanation:

32-20-12.

The leading coefficient and degree of the polynomial 18u - 8u^2 -9 + u^7 are 1 and 7 respectively.

According to the given question.

We have a polynomial 18u - 8u^2 -9 + u^7.

As we know that the leading coefficient of a polynomial is the coefficient of the leading term.

And the highest and the greatest power of a variable in a polynomial equation is called degree of a polynomial.

Here, the leading term of the given polynomial is u^7. Therefore, the leading coefficient of a polynomial is 1.

And the degree of the polynomial is 7.

Hence, the leading coefficient and degree of the polynomial 18u - 8u^2 -9 + u^7 are 1 and 7 respectively.

Answer:

3311

Step-by-step explanation:

The steps are as follows

1. Divide 456 by 5. This gives a quotient of 91 with a remainder of 1. This remainder becomes the least significant digit of the new base number. This would be the right most digit. So the number is _ _ _ 1

2. Take the quotient, 91, divide by 5 again. This gives a quotient of 18 with a remainder of 1. Put this remainder to the immediate left of the previous value. So we have the number as _ _ 1 1

3. Take the previous quotient, 18, divide by 5 again. 18/5 gives quotient of 3 with a remainder of 3. Put this to the immediate left of the previous number giving the number as _ 3 1 1

4. Repeat the division of the new quotient by 5. 3/5 gives a quotient of 0 with remainder of 3 so we stop

Number = 3 3 1 1

The price of the adult's ticket is $20 and the price of a child's ticket is $14.

Let adults = a

Let children = c

The appropriate equation will be:

3a + 4c = 116

2a + 3c = 82

Multiply equation I by 2

Multiply equation ii by 3

6a + 8c = 232

6a + 9c = 246

Subtract

c = 14

Price for children = 14

Since 2a + 3c = 82

2a + 3(14) = 82

2a + 42 = 82

2a = 82 - 42

2a = 40.

a = 40/2

a = 20

Therefore, the price of the adult's ticket is $20 and the price of a child's ticket is $14.

Answer:

Mark has 18 and Don has 73

Step-by-step explanation:

Let M = Mark and let D = Don

D = 4M + 1

D + M = 91

Substitute and solve for M

4M +1 + M = 91

5M = 90

M = 18

Therefore D = 4(18) + 1 = 73

Car A consumes 11.9 gallons.

Car B consumes 13 gallons

Car A consumes 16.3 gallons

Car B consumes 11.6 gallons

In order to determine the required values, the mathematical operation that would be used is division. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.

Gallons that would be consumed when driving  300 mi of city driving plus 100 mi of highway driving:

For Car A = (300 / 36) + (100 / 28) = 11.9 gallons

For Car B: (300 / 29) + (100 / 37) = 13 gallons

Gallons that would be consumed when driving  100 mi of city driving plus 300 mi of highway driving:

For Car A = (100 / 36) + (300 / 28) = 16.3 gallons

For Car B: (100 / 29) + (300 / 37) = 11.6 gallons

The figure will be a sphere with center T and radius 8 1/2 inches, that is, option D.

A circle is a closed curve constituting of the set of all points in a plane that are equidistant from a given point. This point is the center of the circle and the distance is the radius of the circle.

A circle is a 2-dimensional figure, and the two dimensional does not contain the set of all points in the 3-dimensional plane.

A sphere is a round geometrical object and is the set of all points that are equidistant from a given point, in the three-dimensional space.

Here, we are given that there is a point T and we need to describe the collection of all points in the same plane that are 8.5 inches from point T.

Going by the definitions given above, we can infer that it is a sphere with center T and radius 8.5 inches. If we take it to be a circle then it will not include the points in the 3D plane, hence, sphere.

1.5 teaspoons for each dozen

Step-by-step explanation:

A recipe calls for 4.5 teaspoons of sugar for 3 dozen cookies explain the process to find how much is needed for each dozen?

Divide 4.5 teaspoons by 3:

4.5/3 = 1.5 teaspoons for each dozen

since 4.5 teaspoons of sugar will make 3 dozen, we divide 4.5 by 3 to find for each dozen.

The area of the parallelogram is 475.2 square units.

A parallelogram is a polygon with four sides whose each pair of opposite sides are equal and parallel.

The properties of parallelogram are:

Given base b of the parallelogram a 36 units and height h of the parallelogram as 13.2 units.

Therefore we know from the properties of the parallelogram that area is given by the product of base and height.

∴area = b × h

or, area = 36 × 13.2

or, area = 475.2 square units

Hence the area of the parallelogram is 475.2 square units .

An all-terrain vehicle can travel the fastest.

Speed can be define as the time rate by which an object is moving or running along a path. A speed is the quantity which describes the moving rate of any object. We can define the speed with respect to distance and time . Or we can say speed is distance per unit of time . It is calculate in term of kilometers per hour.

Mathematically, we can write:

[tex]Speed = \frac{Distance}{Time}[/tex]

where, distance is measured in km

           and Time is measured in hours

In the question, the distance for three different types of vehicles are given and we have to find fastest vehicle for which we need to find the speed.

For  self-balancing scooter

Time = 1 hour

Distance = 12 miles

Therefore, Speed = 12 miles/h

For all-terrain vehicle

Time = 1 hour

Distance = 12 . 6 = 72 miles

Therefore, speed = 72 miles/h

For a go-kart

Time = 1 hour

Distance = 67 miles

Therefore, speed = 67 miles/h

Hence it is cleared that An all-terrain vehicle can travel the fastest.

Hello,

Step-by-step explanation:

Let's say 2x the smaller number,2x+2 the greater.

2x*(2x+2)=12+(2x)²

2x²+4x=12+4x²

4x=12

x=3

The smaller numbre is 2x=6 and the greater is 8

6*8=48 =12+6²

The range of the data is 5.

Ensure that the score column entries are listed in ascending numerical order. The entries in our example are listed in numerical order.

According to the definition, range is determined for continuous frequency distribution as the difference between the upper limit of the maximum interval and lower limit of the minimum interval of the grouped data.

1. Find the score column entry with the lowest value (with a Frequency greater than 0).

here we have 1 as the lowest entry. The lowest test score is 1.

2. Find the highest entry in the Score column (with a Frequency greater than 0).

here, we have 6 as the highest entry  The highest test score is 6.

Subtract the lowest number (1) from the highest number (6).

6 - 1 = 5

The range of the test scores is 5.

Hence we get the range of the given data as 5.

The value of the z-score is calculated as 0.259.

The standard normal distribution is the variable of a normal distribution to mean 0 and variance 1. The normal distribution follows a bell curve. The z-table aids in determining the area beneath the curve.

Now, as per the given question;

The formula for the z-score is;

z = (x - μ)/σ

x = sample size

σ = standard deviation

μ =  mean of the sample

For the given values in the question;

x = 31.1

σ = 7.7

μ = 30.9

Substitute the given values in the formula to fine z-score;

z-score = (31.1 - 30.9)/7.7

z-score = 0.259

Therefore, the value of the z-score is computed as 0.259.
