Pythagorean theorem is $a^2+b^2=c^2$ , where a and b are the lengths, and c is the hypotenuse. We plug in 102 and 136 in our equation.
$102^2+136^2=c^2$ 102^2+136^2=28900. The square root of 28900 is 170.
170 is the answer

Answer:

x = 170

Step-by-step explanation:

Formula: a² + b² = c²

a = side of right triangle (known as the leg)

b = side of right triangle (also known as the leg)

c = hypotenuse

So we will find the C (x).

a² + b² = c²

136² + 102² = c² (evaluate both 136 and 102.)

18,496 + 10,404 = c² (Add)

28,900 = c²

Now all we need to do is find the square root of 28,900.

√28,900 = √C²

170 · 170 = 28,900

So:

170 = C

x = 170

Step-by-step explanation:

The volume of a cube is

$a {}^{3}$

where a is the side length,

Note: If you want to remember this formula, know that a cube is basically a bunch of squares stacked on one another vertically and horizontally

The area of a square with side length a, is

${a}^{2}$

If we multiply that by the height of the cube, which is a.

${a}^{2} \times a = {a}^{3}$

That is the easy way to derive the formula of the volume of a cube.

Back on track, we know the volume so we must solve for a.

$125 = {a}^{3}$

Assuming you took algebra, to isolate the variable a, we must undo it being raised to the third power.

To do this, we take the cube root of both sides

$\sqrt[3]{125} = \sqrt[3]{a {}^{3} }$

The cube root of 125 is 5 so

$5 = a$

5 cm

$8 = {a}^{3}$

$\sqrt[3]{8} = \sqrt[3]{ {a}^{3} }$

$2 = a$

2 ft

$343 = {a}^{3}$

$a = 7$

7 yd

$1000 = a {}^{3}$

$10 = a$

10 mm

$1728 = {a}^{3}$

$a = 12$

12 in. or 1 ft

$1 = {a}^{3}$

$a = 1$

1 m

The distribution of scores on the SAT is approximately normal with a mean of mu = 500 and a standard deviation of sigma = 100. F

ella [17]

Answer:

a. 2.28%

b. 30.85%

c. 628.16

d. 474.67

Step-by-step explanation:

For a given value x, the related z-score is computed as z = (x-500)/100.

a. The z-score related to 700 is (700-500)/100 = 2, and P(Z > 2) = 0.0228 (2.28%)

b. The z-score related to 550 is (550-500)/100 = 0.5, and P(Z > 0.5) = 0.3085 (30.85%)

c. We are looking for a value b such that P(Z > b) = 0.1, i.e., b is the 90th quantile of the standard normal distribution, so, b = 1.281552. Therefore, P((X-500)/100 > 1.281552) = 0.1, equivalently P(X > 500 + 100(1.281552)) = 0.1 and the minimun SAT score needed to be in the highest 10% of the population is 628.1552

d. We are looking for a value c such that P(Z > c) = 0.6, i.e., c is the 40th quantile of the standard normal distribution, so, c = -0.2533471. Therefore, P((X-500)/100 > -0.2533471) = 0.6, equivalently P(X > 500 + 100(-0.2533471)), and the minimun SAT score needed to be accepted is 474.6653
