B. What is the greatest and least value from the set?

C. What is the median and range?

D. Is the value 85 in the data set? Explain.

Answers

Answer 1

Part A

Answer:   12

Explanation: Count the number of leaves.

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

Part B

Answers: Greatest = 95 , least = 41

Reason:

Look at the largest stem (9) and the largest leaf of this largest stem (5).

This forms the largest value of 95.

The smallest value is 41 since it corresponds to the smallest stem and smallest leaf.

The term "min" and "max" are often used here.

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

Part C

Answers: Median = 68, range = 54

Explanation:

The data set is

41, 52, 57, 58, 65, 66, 70, 75, 78, 80, 81, 95

There are n = 12 items in this set.

Splitting in half gets us n/2 = 12/2 = 6.

The item in slot 6 is 66, and the next item over is 70.

The midpoint of these values is the median. (66+70)/2 = 68.

This midpoint rule only applies if n is even.

To find the range, we subtract the largest and smallest items.

range = max - min = 95 - 41 = 54

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

Part D

Answer: No, 85 is not in the data set

Reason:

The stem 8 doesn't have a leaf of 5 attached to it.

It only has the leaves 0 and 1 to form the numbers 80 and 81.

Every computer that a business owner purchases will lose most of its value after 5 years of use. The owner plans to purchase a computer for $2,100 and replace it after 4 years.Part BMethod 2 of determining the computer's value is to reduce its value by 30% after each year of use.Which function, g(n), represents the value of the computer after years of use for Method 2?g(n) = 0.3n(2,100)g(n) = 0.7 (2.100)g(n) = 2.100(0.3)^ng(n) = 2.100(0.7)^n

Answers

Answer:

D. g(n)=2100(0.7)^nD. g(n)=2100(0.7)^

Explanation:

• The purchase price, i.e. the initial value of the computer = $2100.

,

• The rate at which its value reduces = 30%.

To determine the computer's value after n years of use, we use the depreciation formula below:

[tex]A(n)=P(1-r)^n[/tex]

In this case:

• The Principal, P = $2100

,

• The rate, r = 30%

Substitute these values into the formula.

[tex]\begin{gathered} g(n)=2100(1-30\%)^n \\ =2100(1-\frac{30}{100})^n \\ =2100(1-0.3)^n \\ \implies g(n)=2100(0.7)^n_{} \end{gathered}[/tex]

The function g(n) that represents the value of the computer after n years of use is Option D.

what is the slope of any line parallel to the line 8x+9x=3 in the standard (x,y) coordinate plane ?

Answers

The slope of the line that is parallel to 8x + 9x = 3 is: -8/9.

What is the Slope of Parallel lines?

If two lines are parallel to each other, their slope values is equal to each other. This means the value of "m" in their equation expressed in slope-intercept form as y = mx + b, is the same.

Given the equation of a line in standard form as, 8x + 9y = 3, rewrite this in slope-intercept form:

8x + 9y = 3

8x + 9y - 8x = -8x + 3 [subtraction property of equality]

9y = -8x + 3

9y/9 = -8x/9 + 3/9 [division property of equality]

y = -8/9x + 1/3

The slope of the equation is -8/9. Therefore, the slope of the line that is parallel to the equation 8x + 9y = 3 will also be: -8/9.

Cost of parking for 4 hours:
Cost of parking for t hours:


Pls help me

Answers

Answer:

c = 3t + 11  

t = time in the lot

c = total cost

4 hours the cost will be $23

Step-by-step explanation:

Cost for 4 hours.

c = 3t + 11

c = 3(4) + 11

c = 12 + 11

c= $23

First you have the cost to enter the parking lot which is $11
Then when she leaves the lot shes gonna have to pay $3 every hour she stays there
So if she stays there for 4 hours and getting charged $3 every hour that means in 4 hours she is going to pay $12
So the enter fee + the amount of money over time is going to equal $23

So the answer would be 23$

Mrs. Doctor made a pot of hot chocolate in the teacher’s lounge. She wants to put 2/3 cup of hot chocolate into mugs to share with the other teachers. The pot holds 10 cups. How many mugs will Mrs. Doctor be able to fill?

Answers

Using the mathematical operation of division, Mrs. Doctor can fill 15 mugs using 10 cups.

What is the division operation?

The division operation is one of the basic mathematical operations.

The division operation involves using the divisor to divide the dividend, which results in a quotient.

For instance, since the pot holds 10 cups and the distribution is 2/3 cups for each mug, we can divide 10 cups by 2/3 cups to get 15 mugs.

The quantity of hot chocolate for each mug = 2/3 cups

The total number of cups that the pot holds = 10 cups

The number of mugs that can be filled from 10 cups = 15 (10 ÷ 2/3)

Thus, we can divide 10 cups by 2/3 cups to get the number of mugs Mrs. Doctor can fill.

Karl drove 40 miles in 50 minutes. Teresa drove 35 miles in 42 minutes. Who had a higher average speed?

Answers

The person that has the higher average speed is Teresa.

How to find average speed?

Average speed is calculated by dividing the total distance that something has travelled by the total amount of time it took it to travel that distance.

Therefore, Karl drove 40 miles in 50 minutes and Teresa drove 35 miles in 42 minutes.

The person that has the higher average speed can be calculated as follows;

average speed of Karl = distance / time

average speed of Karl = 40 / 50

average speed of Karl = 4 / 5 miles per minutes

average speed of Teresa = distance / time

average speed of Teresa = 35 / 42

average speed of Teresa = 5 / 6 miles per minutes

Therefore, Teresa had the higher average speed.

How to find angle in a triangle?

A triangle is a polygon with three sides and angles.

The sum of angles in a triangle is 180 degrees.

Therefore, ABC is a triangle and CDE is a also a triangle.

Let's find the angle x in the triangle CDE.

Hence,

∠ACB = 180 - 4x - 49 (sum of angles in a triangle is 180 degrees)

∠ACB =  180 - 49 - 4x

∠ACB = 131 - 4x

Therefore,

180 = ∠DCE  + ∠DEC  + ∠CDE  

∠CDE   = 100°

∠DEC = x

∠DCE = ∠ACB = 131 - 4x

Hence,

180 = 131 - 4x + x + 100

180 = 231 - 4x + x

180 - 231 = -3x

-51 = -3x

divide both sides by -3

x = -51 / -3

x = 17

Answers

The largest prime factor that always divides the sum of the terms in the sequence is 37.

The sequence is finite and consists of three-digit integers.

The tens and units digits of each term are, respectively, the hundreds and tens digits of the next term, and the tens and units digits of the last term are, respectively, the hundreds and tens digits of the first term.

From the above property of the sequence, we can see that each digit at the units, tens as well as hundreds place will appear the same number of times in the sequence.

Let "x" be the sum of the digits at unit place in all the terms.

The sum of all the terms is "S".

S = 111*x

S = 3*37*x

We can clearly see that the sum "S" is divisible by 37.

Hence, the largest prime factor that always divides the sum of the terms in the sequence is 37.

What is the area of the trapezoid?

A trapezoid is simply a quadrilateral with at least one pair of parallel sides.

The area of a trapezoid is expressed as;

A = 1/2 × ( a + b ) × h

Where a is length of base a, b is length of base b and h is the height.

Given the data in the diagram;

Length of base a = 8cmLength of base b = ( a + 6cm ) = 8cm + 6cm = 14cmHeight h = 8cmArea A = ?

To determine the area of the trapezoid, plug the given lengths into the above formula and solve for A.

A = 1/2 × ( a + b ) × h

A = 1/2 × ( 8cm + 14cm ) × 8cm

A = ( 8cm + 14cm ) × 1/2 × 8cm

A.$669.11B.$674.43C.$886.41D.$512.63 a binary search algorithm searches for a target value within a sorted array. binary search compares the target value to the middle element of the array; if they are unequal, the half in which the target cannot lie is eliminated and the search continues on the remaining half until the target value is found or until a search can no longer be performed. this problem can be solved using which of the techniques? Write a program that repeatedly reads in integers until a negative integer is read. The program also keeps track of the largest integer that has been read so far and outputs the largest integer at the end.
