You want to buy birthday hats, cards, and teddy bears for your best friends birthday party. You buy the products for wholesale prices, from the local party store.

The hats cost $2.50, cards cost $0.90, and the teddy bears cost $3.10. You want to decorate each item for the party and the decorations for the hats cost $1.50, the decorations for the cards cost $0.60, and the decorations for the teddy bears cost $1.70.

In your own words, explain how you would construct a matrix to contain this data. Make sure you include the size and shape of the matrix and your logic for your construction methods.

Answers

Answer 1

Answer:

I will create a five by four matrix to indicate the costs of the products.  The matrix will have five vertical columns and four horizontal rolls.  The vertical columns will show the product categories and the total costs for all the products and decorations.  The horizontal rolls will show the product costs, the decoration costs, and the total costs for each product category.

The size and shape of the matrix will be 5 by 4 with squared boxes.

Step-by-step explanation:

Products/Costs         Hats         Cards      Teddy    Total Costs

Product costs           $2.50       $0.90       $3.10        $6.50

Decoration costs      $1.50       $0.60        $1.70        $3.80

So you have 12 miles on that trail, and markers every 2/3 of the way there. If you were to divide 2 with 3 then you can get the decimal of the fraction. Which in this case it’s 0.75. So every single 0.75 of the mile there is a marker. Divide 12 with 0.75 and you get 16 markers.

Kendrick is using a compass and straightedge to copy angle M the figure shows the portion of the construction that he has already completed where should Kendrick place the center of the compass to do the next step of the construction

Answers

Answer:

The next step of the construction is;

Place the compass at point N and adjust the width to the point where the arc crosses the other side leg of the angle

Step-by-step explanation:

The steps to copy an angle are;

1) Mark the point C of the vertex of the new angle

2) Draw a ray from C in the desired direction

3) With the compass placed at M of the original angle, draw an arc that crosses both sides of the original angle. Mark the crossing points N and O

4) With the same compass width from the arc drawn in the above step, draw a similar arc that crosses the ray from C at point D

5) Place the compass at point N and adjust the width to point O, the point where the arc crosses the other side of the angle

6) While the adjusted compass width is held to remain the same, place the compass at point D and draw an arc to cross the previous arc drawn from C and label the intersection point E

7) With the straight edge, draw a ray FC that passes through E to point C to complete the copied angle.

If sets A and B have the same number of terms, is the standard deviation of set A greater than the standard deviation of set B? 1.The range of set A is greater than the range of set B. 2. Sets A and B are both evenly spaced sets.

Answers

Step-by-step explanation:

(1) The range of set A is greater than the range of set B.

This statement  gives only the range which means only outermost values but what about the other values. For example-11,0,0,0,11 and -10,-10,0,10,10

Clearly, Former one has higher range but lower standard deviation.

(2) Sets A and B are both evenly spaced sets.

Evenly spaced is fine. However, we don't know the spacing since that is required to know the deviation.

For, example, sets A{2,4,6,8,10} and B {1,2,3,4,5} so in this case SD of A> SD of B. Or,  we can have B{2,4,6,8,10} and A{1,2,3,4,5} so in this case SD of B> SD of A.

A group of 4 friends likes to golf together, and each friend keeps track of her all-time lowest score in a single round. Their low scores are all between 90 and 100, except for Angie, whose low score is 80. Angie then golfs a great round and has a new low score of 75. How will decreasing Angie's low score affect the mean and median?

Answers

Answer: Mean get decreased and median remains same.

Step-by-step explanation:

Given: The low scores of all 4 friends  are all between 90 and 100, except for Angie, whose low score is 80.

i.e. Angie is an outlier.

[An outlier is an extreme value which lies far from the other data values.]

Angie then golfs a great round and has a new low score of 75.

i.e. more lower value.

Since Mean gets effected by an outlier but median remains same.

Here, value of new outlier(75) is less than the previous one (80), so mean score will get decreased, where as median (middle most value in ordered data) remains the same.

The graph of a linear equation is a straight line.

The graph has a positive slope and it passes through the origin

The given parameters are:

[tex]\mathbf{m =\frac 23}[/tex]

[tex]\mathbf{(x,y)= (0,0)}[/tex]

A linear equation is represented as:

[tex]\mathbf{y = mx + b}[/tex]

[tex]\mathbf{m =\frac 23}[/tex]

So, we have:

[tex]\mathbf{y = \frac 23 x + b}[/tex]

[tex]\mathbf{(x,y)= (0,0)}[/tex] represents the y-intercept (i.e. b = 0).

So, we have:

[tex]\mathbf{y = \frac 23 x + 0}[/tex]

[tex]\mathbf{y = \frac 23 x}[/tex]

See attachment for the graph of [tex]\mathbf{y = \frac 23 x}[/tex]

D. The statement is true. Since there is a coefficient on the variable, the Division Property of Equality must be used first.

Answers

Answer:

The correct option is;

C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing

Step-by-step explanation:

In other to solve the equation 4·b + 3 = 11, we have;

By the subtraction property of equality, we have;

Firstly we subtract 3 from both sides gives;

4·b + 3 - 3= 11 - 3

Next we apply the division property of equality, we have;

Both sides of an equation remain equal when we divide both sides of the equation by the same, non-number,

Dividing both sides by 4, gives;

4·b/4 = 8/4

b = 8/4 = 2

The solution to the equation, 4·b + 3 = 11 is b = 2.

what is the slope of a line that passes through the points ( 3,7) and(12,7)?​

Answers

Answer:

The slope is 0.

Step-by-step explanation:

To find the slope, we can do (7 - 7) / (12 - 3) = 0 / 9 = 0. This makes sense because if we look at the points, they both have the same y-coordinate, so we know that as x increases / decreases, y never changes. Because y never changes, the slope is 0.

Answer:

m=0

Step-by-step explanation:

To find slope, it is y2-y1/x2-x1

Therefore, x1=3, x2=12, y1=7 and y2=8

Plugging those variables in,

(7-7)/(12-3)=

7-7=0

12-3=9

0/9=0

Therefore, slope of the line that passes through points (3,7) and (12,7) is 0

On a certain map, 3 centimetres represents 25 kilometres. How many kilometres does 1 1/2 decimeters represent?

Answers

Answer:

125 kilometres does 1 1/2 decimetres represent

Step-by-step explanation:

Given

3 cm = 25 KM  (Representative)

we have to find value of 1 1/2 decimetre

1 1/2 decimetre = (1*2+1)/2 decimetre = 3/2 decimetre

we know

1 decimetres = 10 cm

3/2 decimetres = 3/2 *10 cm = 15 cm

thus, we have to find 15 cm on the 3 cm = 25 KM map.

3 cm = 25 KM

1 cm = 25/3 KM

15 cm = 15*25/3 KM = 125 KM

Thus,

125 kilometres does 1 1/2 decimetres represent

In 1893 Hogan registered the "Orphan Lode" or "Orphan Mine," located 1,000 feet below Maricopa Point and on 20.64 acres of scenic property less than two miles west of today's village. Four acres abutted the canyon edge while the remainder plummeted to the copper mine's shaft in the cliff face below. Hogan constructed two trails to his claim. The Battleship Trail followed the upper 1.4 miles of the Bright Angel Trail before traversing below Maricopa Point another 3.5 miles to the mine site. Another trail consisted of ropes, ladders, and toe holds chiseled into the side of the cliff from the rim directly above the mine site.

Hogan not only had the mine, but was also able to build tourist facilities uncontrolled by the National Park Service. In 1936, he opened the Grand Canyon Trading Post, eventually adding cabins and a saloon. World War II ended his mining and tourism business, and Hogan sold out to Madeleine Jacobs in 1946. Jacobs operated the tourist facilities with little interest in the mine until 1951, when it was discovered that the black rock she had been kicking aside was actually some of the richest uranium in the Southwest. The Orphan Mine became one of the most productive uranium mines in the region, in operation from 1953-1969. An 1,800-foot-long cable tram was added in 1955. A large "bucket" carried miners down and back from the rim to the mine opening in the cliff below, and hauled out the excavated ore. Each bucket could hold 800 pounds of ore, with an average of 1,000 tons removed each month. In 1959, to meet higher safety standards and increased production demand, the cable tram was replaced by an elevator and load car operated from a large headframe. A 1,500-foot vertical shaft was drilled straight down from the rim to the mine site. Miners had a long, dark ride into the mine below. Ore production increased to almost 9,000 tons each month. In the late 1950s, the mining company sought permission to extend the operation beyond the mining claim and into federal property. To speed the approval process they proposed an 18 story, 800-room hotel overhanging the rim. This grand hotel would spill "down the side of the precipitous cliff like a concrete waterfall" ending at a swimming pool and sun deck below. Because of the controversy over the extended mining operations and the unprecedented hotel plans, Congress passed a law in 1962 that allowed a compromise. Mining could continue, but tourist operations were prohibited after 1966, and all mining would cease by 1987, when the property would then pass to the federal government. Mining actually stopped by 1969 when the market for uranium declined and shipping costs for the ore increased. When the mine closed it had produced 495,107 tons of ore, including 4,257,571 pounds of uranium oxide, 6,680,000 pounds of copper, 107,000 pounds of silver, and 3,283 pounds of vanadium oxide. The value of the uranium alone has been estimated at $40 million. 4 Select all the correct answers.
