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.

Jamal performed an experiment flipping a coin. He did 10 trials and then his arm got tired. He recorded his results in the table. Based on the experimental probability, Jamal predicted that the number of times the coin lands heads up will always be greater than the number of times it lands tails up. What is the error in his prediction?

A 3-column table with 2 rows. Column 1 is labeled Coin with entries heads, tails. Column 2 is labeled Observed frequency with entries 8, 2. Column 3 is labeled Experimental probability with entries 0.80, 0.20.
He should have performed fewer trials before comparing them to the theoretical probability.
He did not need to perform the experiment to compare theoretical and experimental probabilities.
He should have subtracted the theoretical probability from the experimental probability.
He did not perform enough trials to compare the theoretical and experimental probabilities.

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)

Answers

Answer:

B 30°

Step-by-step explanation:

come now.

the sum of all angles around one point on one side of a line is 180°.

why ?

because any line with a point can be seen as a diameter of a circle with that point as center.

and every side of the line represents then a half-circle.

and a half-circle stands for 360/2 = 180°.

so,

180 = (2x + 70) + (x - 10) = 2x + 70 + x - 10 = 3x + 60

120 = 3x

x = 40

2x + 70 = 2×40 + 70 = 80 + 70 = 150°

x - 10 = 40 - 10 = 30°

180 = Q + (2x + 70) = Q + 150

30° = Q

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{9600 miles}{5280}[/tex] = 1.8181... This is a repeating number

1.8181... is larger than 1.8

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

Jackie has 8 friends, and each friend has 10 nails. So Jackie needs to paint a total of 8 x 10 = 80 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.

Answer:

Step-by-step explanation:

The value of angle ADC is 157.4°

How do you find angle In a trapezium?

The sum of angles in a trapezoid-like other quadrilateral is 360°. So in a trapezoid ABCD, ∠A+∠B+∠C+∠D = 360°. Two angles on the same side are supplementary, that is the sum of the angles of two adjacent sides is equal to 180°. The length of the mid-segment is equal to 1/2 the sum of the bases.

Therefore angle A + angle D = 180

using trigonometry,

cos A = 12/13

A = cos^-1(0.923)

A = 22.63°

therefore angle D = 180-22.63

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!
