Answers
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!

If Jason ran 1.8 miles and Josh ran
3,200 yards, who ran the farthest?
(1 mile = 5,280 feet)
Answers
Answer: Josh ran the farthest.
Step-by-step explanation:
1 mile = 5,280 feet
1.8 miles = 1.8 x 5,280 feet = 9,504 feet
1 yard = 3 feet
9,504 feet = 9,504 / 3 yards = 3,168 yards
So Jason ran 3,168 yards.
Since 3,200 yards is greater than 3,168 yards, Josh ran the farthest.
Answer:
Josh ran further
Step-by-step explanation:
I converted Josh's yards to miles.
[tex]\frac{3200yards}{1 }[/tex] · [tex]\frac{3 feet}{1 yard}[/tex] · [tex]\frac{1 mile}{5280feet}[/tex] cancel out the words that you see on the top and on the bottom
[tex]\frac{3200}{1}[/tex] · [tex]\frac{3}{1}[/tex] [tex]\frac{1mile}{5280}[/tex] Now simplify by multiplying
[tex]\frac{9600 miles}{5280}[/tex] = 1.8181... This is a repeating number
1.8181... is larger than 1.8

Gusto's Department Store offers gift-wrapping services to their customers, and the manager at Gusto's needs to order more ribbon. Small gift boxes use 21 inches of ribbon, while large ones use 30 inches of ribbon. The manager at Gusto's expects to sell 200 small boxes and 220 large boxes this month. If the ribbon they use is sold by the yard, how many yards of ribbon should the manager order?
Answers
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.

A car dealership has various combinations of vehicles in their car lot, all of which have an equally likely chance of being selected.
Use the list of options below to determine the probability of each vehicle being selected. The problem is based on independent events.
Answers
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)

First you need to draw in a diagonal across the "floor" of the room connecting 2 vertices. You should draw the diagonal so that it's going in the same direction as the spider's thread; the diagonal is drawn in the wrong way if it intersects across the spider's thread.
Then you need to mark in the measures. The figures that are parallel to each other are congruent, so they have equal measures. For example, the rectangle that is parallel to the 6 by 8 one has the same measures as that one. Also, all of the walls of the room are rectangles. That means that the opposite sides of each rectangle have equal measures.
Because the diagonal divides the rectangle into 2 right triangles, you can then use the Pythagorean theorem to find the length of the diagonal that you drew in. (12 squared + 8 squared = length of the diagonal squared, and solving gives you the length of the diagonal as the square root of 208)
Finally, you can see that there is another right triangle formed with the diagonal that includes the spider's thread. With the length of the diagonal and the length of 6 ft, you can use the Pythagorean theorem to find the length of the spider's thread. (6 squared + the square root of 208 squared = length of the thread squared) The length of the spider's thread is the square root of 244, which is 15.6 ft rounded to the tenth's place.
Jackie plans to plans to paint the finger nails of 8 friends. She finishes painting 4 of her friends nails. If each friend has ten nails to paint, how many nailes does Jackie still need to paint? Write and solve an equation to show how many more nails Jackie needs to paint.
Answers
Answer:40
Step-by-step explanation:
each friend has 10 nails and there is a total of 8, 8 x 10 80 - 40 = 40 in other words Jackie has to paint 40 finger nails
If Jackie has already painted 4 friends' nails, she has painted 4 x 10 = 40 nails.
To find out how many more nails Jackie needs to paint, we can subtract the number of nails she has already painted from the total number of nails she needs to paint:
80 - 40 = 40
So Jackie still needs to paint 40 nails.
