A plane travel 216 miles per hour
Work out an estimate for how many seconds it takes to travel in 1 mile.

Step-by-step explanation:

Length of hypotenuse = c

Length of legs = a and b

Hence,

→ a² + b² = c²

→ b² = c² - a²

→ b = √(c² - a²)

First one is correct. [a]

Now,

By Pythagoras theorem,

→ a² + b² = c²

Third one is correct too. [c]

→ a² + b² = c²

→ a² = c² - b²

Second one is also correct. [b]

Step-by-step explanation:

The second leg's length is 12.

Explanation:

Math Warehouse

We'd use the pythagorean theorem to solve for the other leg's length. As the image suggests, we'd use the theorem, a2+b2=c2.

If one leg is 9, that's our a value. 

If the hypotenuse is 15, that's our c value.

Now we just have to find the b value.

Plugging in the variables, 92+b2=152.

92=81.

152=225.

81+b2=225. Subtract 81 from both sides.

b2=144. Square root both sides.

√b2=b and √144=12, so b=12

Using the hypergeometric distribution, it is found that there is a 0.0333 = 3.33% probability that all three tickets have no value.

The tickets are drawn without replacement, hence, the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability that all three tickets have no value is P(X = 0), hence:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 0) = h(0,60,3,20) = \frac{C_{20,3}C_{40,0}}{C_{60,3}} = 0.0333[/tex]

0.0333 = 3.33% probability that all three tickets have no value.

Step-by-step explanation:

the small square at the right repsents a 90° angle which means it is righ, since acute means the angle is smaller than 90°. all 3 sides of this triangle are equal which means it is isoceles as scalene is when all sides of said triangle are at different lengths, which this one is not. hope that helps.

Answer: 8,580

Step-by-step explanation:

The equation for the years are 6,600+y(0.03x), x being the original healthcare price 6,600, and y being the number of years elapsed since 2007. Since 10 years have elapsed, the answer would be

6,600+10(198)

Or 6,600+1,980

Answer:

15cm

Step-by-step explanation:

As we know that in two similar triangles the corresponding sides are proportional . So that ,

=> 4/10 = 6/AB

=> AB = 6 * 10/4

=> AB = 6 * 5/2

=> AB = 15 cm

Answer:

Ans: C) 15cm

Step-by-step explanation:

first you need to find its corresponding sides,

so, 10÷4=2.5

therefore, 6×2.5=15cm (multiple if we are find the big shape)

So, Ans: is 15cm

Answer:

-0.01x² + 4x + 200

Step-by-step explanation:

To find the difference in profit between the two companies we need to subtract the polynomials.

So,

________________

-0.03x² + 25x - 1500

MINUS

-0.02x² + 21x - 1700

________________

(-0.03x² - (-0.02x²)) = -0.01x²

(25x - 21x) = 4x

(-1500 - (-1700)) = 200

Thus, the difference is

-0.01x² + 4x + 200

Changing the point of view will cause completely different narrative of a story. You will never know the character's own thoughts, motifs of doing something and his/her perception of everything will not be that clear as it can be depicted in first point of view, when character tell you his story personally. If it was narrated in first person from other character you would never found out what is really true in the story.
