The probability being fixed at 1/3, let's find which event in rolling a 6 sided dye will generate a probability of 1/3.

A- 6 sided number cube: with one roll (INCORRECT), however with a 3 sided number cube, P(0ne roll) = 1/3 (CORRECT)

B- A roll of an even number : P(even number) =3/6 =1/2 (INCORRECT), and a roll of an odd number P(odd number) = 3/6 = 1/2 (INCORRECT)

C- A roll of a number less than 3 , P(less than 3) =2/6 =1/3 CORRECT), whereas :a roll  greater than or equal to 3. INCORRECT

D. A roll of a number that is not divisible by 3, P(not divisible by 3) = 4/6 =2/3 (INCORRECT): P( number number that is divisible by 3) =2/6 1/3 CORRECT

The measure of the angle will be equal to 58°.

The supplementary angles are defined as the angles whose sum is equal to 180°

here the angle is 122° degrees more than its supplementary angle.

We know that the sum of the two supplementary angles is given as:-

Suppose the known and the unknown angles are A and B respectively.

∠A  +  ∠B  =  180°

122  + ∠B  = 180°

∠B  =  180-122= 58°

Hence the measure of the angle will be equal to 58°.

The unit rate of the lemonade is $0.2 per ounce.

A unit rate means a rate for one of something.

Given that, Justin sells 78.5 ounces of lemonade for a total of $15.70.

We are asked to find the unit price in dollars per ounce.

Since, he sells 78.5 ounces in $15.70

So, in one ounce will be sold in = 15.70 /78.5 = 0.2

Hence, the unit rate of the lemonade is $0.2 per ounce.

Answer:

if its 16 then its 24

Step-by-step explanation:

Answer: -17 or anything above that

Step-by-step explanation:

You have to isolate k so in order to do that, you must subtract 11 from both sides to get -16 > k so it has to be anything less than -16 which is -17 or anything higher than that.

Answer:

65°

Step-by-step explanation:

We know that every triangle is equal to 180 degrees. Therefore, you have to subtract all angles by 180 to find what the missing angle is. The missing angle is 180-68-47. You can simplify this to 180-115. This is equal to 65. Therefore, the missing angle is 65 degrees.

Answer: 56/209

Step-by-step explanation:

Answer:

Here's what we know:

A = Lw (Area is length times width)

L = 2w + 6 (length is twice the width plus 6)

A = 140 (Area is 140 m2)

Plug in the variable values:

140 = w(2w + 6)

Distribute:

140 = 2w2 + 6w

Subtract 140:

2w2 + 6w - 140 = 0

Factor out a 2:

2(w2 + 3w - 70) = 0

Divide both sides by 2:

w2 + 3w - 70 = 0

(w + m)(w - n)

When we factor out the quadratic, we know it's going to be a +/- situation because the c value in the quadratic is negative, and the two numbers are going to be three away, the plus next to the 3 meaning that the larger number is going to be positive:

(w + 10)(w - 7) = 0

w = -10, 7

We can't have a negative length, so we can toss out the -10, leaving us with w = 7 meters.

L = 2 * 7 + 6

L = 14 + 6

L = 20

Check:

140 = 20 * 7

140 = 140

Answer:

$193.50

Step-by-step explanation:

start by multiplying 240 by .25 (25%) to find out how much is 25% of 240. this equals 60.

then, subtract $60 from $240. equals 180.

next, to add the sales tax, multiply 180 by 0.075 (7.5%) this is $13.50.

lastly, add the tax, which is $13.50, to the suit's sale price, which is $180.

180+13.5= $193.50

Pluto

Pluto is named after the Roman god of the underworld.

This was proposed by Venetia Burney an eleven year old schoolgirl from Oxford, England.

Pluto was reclassified from a planet to a dwarf planet in 2006.

This is when the IAU formalised the definition of a planet as “A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.”

Pluto was discovered on February 18th, 1930 by the Lowell Observatory.

For the 76 years between Pluto being discovered and the time it was reclassified as a dwarf planet it completed under a third of its orbit around the Sun.

Pluto has five known moons.

The moons are Charon (discovered in 1978,), Hydra and Nix (both discovered in 2005), Kerberos originally P4 (discovered 2011) and Styx originally P5 (discovered 2012) official designations S/2011 (134340) 1 and  S/2012 (134340) 1.

Pluto is the largest dwarf planet.

At one point it was thought this could be Eris. Currently the most accurate measurements give Eris an average diameter of 2,326km with a margin of error of 12km, while Pluto’s diameter is 2,372km with a 2km margin of error.

Pluto is one third water.

This is in the form of water ice which is more than 3 times as much water as in all the Earth’s oceans, the remaining two thirds are rock. Pluto’s surface is covered with ices, and has several mountain ranges, light and dark regions, and a scattering of craters.

Pluto is smaller than a number of moons.

Mars

Mars and Earth have approximately the same landmass.

Even though Mars has only 15% of the Earth’s volume and just over 10% of the Earth’s mass, around two thirds of the Earth’s surface is covered in water. Martian surface gravity is only 37% of the Earth’s (meaning you could leap nearly three times higher on Mars).

Mars is home to the tallest mountain in the solar system.

Olympus Mons, a shield volcano, is 21km high and 600km in diameter. Despite having formed over billions of years, evidence from volcanic lava flows is so recent many scientists believe it could still be active.

Only 18 missions to Mars have been successful.

As of September 2014 there have been 40 missions to Mars, including orbiters, landers and rovers but not counting flybys. The most recent arrivals include the Mars Curiosity mission in 2012, the MAVEN mission, which arrived on September 22, 2014, followed by the Indian Space Research Organization’s MOM Mangalyaan orbiter, which arrived on September 24, 2014. The next missions to arrive will be the European Space Agency’s ExoMars mission, comprising an orbiter, lander, and a rover, followed by NASA’s InSight robotic lander mission, slated for launch in March 2016 and a planned arrival in September, 2016.

Mars has the largest dust storms in the solar system.

They can last for months and cover the entire planet. The seasons are extreme because its elliptical (oval-shaped) orbital path around the Sun is more elongated than most other planets in the solar system.

On Mars the Sun appears about half the size as it does on Earth.

At the closest point to the Sun, the Martian southern hemisphere leans towards the Sun, causing a short, intensely hot summer, while the northern hemisphere endures a brief, cold winter: at its farthest point from the Sun, the Martian northern hemisphere leans towards the Sun, causing a long, mild summer, while the southern hemisphere endures a lengthy, cold winter.

Step-by-step explanation:

to find the IQR you do Q3-Q1

2.00-1.93

Answer:

Yes.

Step-by-step explanation:

Use the Pythagorean Theorem and Pythagorean triples.

One commonly used Pythagorean triple is 3, 4, 5.

24 is a multiple of 3 (3*8=24), 32 is a multiple of 4 (4*8=32), and 40 is a multiple of 5 (5*8=40). This concludes that the numbers 24, 32, and 40 can be the lengths of the three sides of a right triangle.

To further check our response, we can use the Pythagorean Theorem.

a^2+b^2=c^2

24^2+32^2=40^2

576+1024=1600

1600=1600

Our response is correct.
