Find a value for x that makes the equation true. 3(10 - x) = 6

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.

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

Answer:

$213.41

Step-by-step explanation:

To do this question, you have to use the formula for compound interest:

A=P(1+r/n)^nt

The A is the final amount of money you make which is $237.60. P is your initial amount that you are trying to solve for. R is the rate of interest. However, for r you have to convert the percent into a decimal so divide 1.2 by 100, which would be 0.012. N is the number of times it is compounded annually which is once. And finally, t is the number of years taken, which is 9. If you substitute the numbers into the equation it should look like this:

237.60=P(1+0.012/1)^1*9

If you solve for P, you should get $213.41.

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
