Answer:  300 yards of ribbon

Step-by-step explanation:

First of all, because we are working with inches, and need to find an answer in yards, we need to know how many inches are in a yard.

There are 36 inches in a yard.

Next, we need to multiply 21 inches by 200 small boxes, and 30 inches by 220 large boxes. We do this to find out how many inches of ribbon Gusto's needs for each size box.

The products are are 4,200 small boxes, and 6,600 large boxes.

The products (the answers to the multiplication problems) them need to be added together. We do this because we need to find how much total ribbon the manager of Gusto's needs to order.

The sum (the answer to the addition problem) of 4,200 + 6,600 = 10,800.

Lastly, we divide 10,800 by 36 (remember there are 36 inches in a yard). We do this to find the number of total yards of ribbon the manager will need to order for the month.

The quotient (the answer to the division problem) is 300.

Our answer is 300 yards of ribbon.  

I hope that helps you out!

Answer: 3 is 0 and 4 is unidentified

Step-by-step explanation:

The horizontal line has a slope of zero, think of it as you can walk on it or not. Since four has all X's as eight that creates a vertical slope which cannot be walked on.

Thanks for the opportunity to help you! :)

1. m/slope=6/1 or 6. Use the first two points for the formula y₂-y₁/x₂-x₁. B

2.m=-4 or -12/3. Use the slope formula and substitute the points. G

3. m=zero. I

4.m=undefined. A

Step-by-step explanation:

To find the length of a rectangular prism, there should be two missing sides. Since we don't have length or width, you find what times 8 times another number equals 250.

Answer:

0.083 or 8.3%

Step-by-step explanation:

Since there are initially four cards, each card has a 25% (or 1/4) chance of being chosen. So the 8 card would have a 1/4 chance of being chosen.

Since the first card was chosen and not put back into the deck, the percent chance of each chosen card changes from 25% to about 33.3% (or 1/3) chance of being chosen. So the 8 card would now have a 1/3 chance of being chosen.

Since the question is asking what the percentage of choosing an 8 twice without replacing it is, you would multiply each of the percent chances that 8 card has to be chosen. In this case, multiply 1/4 and 1/3

This will result in about 0.083. To change to a percentage, multiply by 100 and the answer will end up at 8.3%.

Answer: 0%

Step-by-step explanation:

If you pick a 8 the first time, and you don't put it back, then there is no chance to get a 8 the second time. However, fi you pick a number other than 8 the first time, and pick 8 the second time, you didn't get 8 both times. Hope this helps!

Answer:The Allstars, with 67.1333...

Answer:

The mistake appears in step 1 where 23.8 is divided by 14 instead of 2.

The correct first step should be: (23.8 / 2) + 12 + (14.5 / 2)

Hope this helps!

Answer:

A

Step-by-step explanation:

The error arises in the equation "(23.8 / 2 + 12)", where the division is incomplete. A slick fix is to rephrase it as "(23.8 / 2) + 12" to ensure accurate calculation, with the division taking precedence over addition, resulting in a cooler computation!

Answer:

Step-by-step explanation:

The probabilities of each of the following combination in question is 1/8, 1/6, 1/8, and 1/12 respectively.

The car dealership offers combinations of car parameters. The possible values of each car parameter are :

Vehicle = [Sedan, Suv, Truck]

Exterior color = [Red, Blue, Silver, Black]

Interior Material = [Leather, Cloth]

1. The probability of selecting a Silver Vehicle with a Cloth Interior is 1/8.

P(Silver, Cloth) = P(Exterior = Silver, Interior=Cloth)

                       = P(Exterior = Silver) * P(Interior=Cloth)

                       = (1/Total exterior options) * (1/Total interior options)

2. The probability of selecting an SUV or Truck with a Red or Black color and Cloth Interior is 1/6.

P(SUV|Truck, Red|Black, Cloth)

                       = P(Vehicle=Suv|Truck, Exterior = Red|Black, Interior=Cloth)

                       =  P(Vehicle=Suv|Truck) * P(Exterior = Red|Black) * P(Interior=Cloth)

                       = (2/Total vehicle options) * (2/Total exterior options) * (1/Total interior options)

3. The probability of selecting a Sedan of a non-Red color and Cloth Interior is 1/8.

P(Sedan, !Red, Cloth)

                       = P(Vehicle=Sedan, Exterior != Red, Interior=Cloth)

                       =  P(Vehicle=Sedan) * (1- P(Exterior = Red)) * P(Interior=Cloth)

4. The probability of selecting a Truck of a Blue or Black color and Leather Interior is 1/12.

P(Truck, Blue|Black, Leather)

                       = P(Vehicle=Truck, ExteriorBlue|Black, Interior=Leather)

                       =  P(Vehicle=Truck) * P(Exterior = Blue|Black)) * P(Interior=Leather)

Answer:

Option 11 is correct.

Step-by-step explanation:

The values of the expression 4x − y when x = 3 and y = 1 will be 11.

Answer:11

Step-by-step explanation: 4*3-1=12-1=11

Answer:

The length of the missing side is 21 cm.

Step-by-step explanation:

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

[tex]a^{2}[/tex] + [tex]28^{2}[/tex] = [tex]35^{2}[/tex]

[tex]a^{2}[/tex] + 784 = 1225

[tex]a^{2}[/tex] + 784 - 784 = 1225 - 784

[tex]a^{2}[/tex] = 441

[tex]\sqrt{a^{2} }[/tex] = [tex]\sqrt{441}[/tex]

a = 21

=1716 cm

The requried surface area of the given prism is 1716 square centimeters.

The surface area is the total area that covers the surface of a three-dimensional object. It is calculated by adding up the area of all the faces or surfaces of the object. For example, the surface area of a cube can be calculated by adding up the areas of all six faces.

Here,
The surface area of the given prism is given as:

Surface area = 5*20 + 10*20 +20*8 + 11*20+2[5*10+16*8]+16*20+20*18

Surface area = 1716 square centimeters

Thus, the requried surface area of the given prism is 1716 square centimeters.

What is a scatter plοt?

A scatter plοt is a graph that displays values fοr twο variables as οrdered pairs οf data pοints, with οne variable οn the hοrizοntal axis (x-axis) and the οther variable οn the vertical axis (y-axis).

Tο determine which twο pοints a line οf fit wοuld gο thrοugh tο best fit the data in a scatter plοt, we need tο lοοk fοr the pοints that are clοsest tο the general trend οr directiοn οf the pοints. In this scatter plοt, it appears that the general trend is a dοwnward slοping line.

The twο pοints that wοuld best fit this trend are (1, 9) and (10, 1), which are lοcated at the twο ends οf the scatter plοt and appear tο be the farthest frοm the general trend. Therefοre, the answer is:

(1, 9) and (10, 1)

Hence, pοints (1, 9) and (10, 1) wοuld be a line οf fit.
