Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 1 more than 4 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 91 ?
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

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.

14. Model Real Life A self-balancing scooter travels 12 miles
per hour. An all-terrain vehicle can travel 6 times as
fast as the scooter. A go-kart can travel 67 miles
per hour. Which vehicle can travel the fastest?
An all-terrain vehicle can travel the fastest.
What is Speed ?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.

Consider a set of data in which the sample mean is 30.9 and the sample standard deviation is 7.7. Calculate the z-score given that x = 31.1. Round your answer to
two decimal places.
The value of the z-score is calculated as 0.259.
What is descried as normal distribution?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.
The normal distribution is also known as the Gaussian distribution, after just a German mathematician.The t-distribution is another distribution that may be described as having a bell shape. It differs as from normal distribution in that the tails are thicker. It is commonly employed in the analysis of small sample size datasets.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.

Jen Butler has been pricing Speed-Pass train fares for a group trip to New York.
Three adults and four children must pay $116
Two adults and three children must pay $82
Find the price of the adult's ticket and the price of a child's ticket.
The price of the adult's ticket is $20 and the price of a child's ticket is $14.
How to calculate the valuesLet 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.

456 in base 5
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

Find the 10th term
Answer:
15.479
Step-by-step explanation:
This is a geometric series with common ratio of 6/5
Any term is 6/5 times the previous term
The general formula for the nth term of a geometric series given the common ration r and the first term a₁ is
[tex]a_n = a_1\cdot r^{n-1}[/tex]
Here r = 6/5 and n = 10
So the 10th term is
[tex]a_{10} = 3\cdot(\dfrac{6}{5})^9[/tex]
= 3 x (6⁹/5⁹) = 3 x (10077696/1953125) = 30233088/1953125 = 15.479
Which describes the collection of all points in the same plane that are 81/2 inches from point T
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.

the tiles (right angled triangles) are arranged around a parallelogram-shaped tile. Calculate the area of the parallelogram. b= 36 h= 13.2
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:
Both pairs of opposite side are equal and parallel .Both diagonals are equal.Each diagonal divides the parallelogram into 2 congruent triangles.Squares , rectangles and rhombus are parallelograms.The area of a parallelogram is given by the product of base and height of the parallelogram.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
