Which angles are corresponding angles?

BartSMP [9]

For now, let's assume we can rule out choice A.

Angles 3 and 7 are vertical angles. So we can rule out choice B

Angle 3 and angle 11 are corresponding angles. They are on the topside of their adjacent parallel horizontal line. They are also on the left side of the transversal cut line d. The answer is choice C.

Angles 3 and 8 are not corresponding angles. Corresponding angles are not adjacent to one another. In other words, they do not share a common vertex.

The cube root of a number is 2. Write an equation, using x, that represents this situation.

Kay [80]

Answer:

x - 8 = 0

Step-by-step explanation:

Since, the cube root of a number is 2.

Let the number be x.

Therefore,

$\sqrt[3]{x} = 2 \\ cubing \: both \: sides \\ {( \sqrt[3]{x})}^{3} = {(2)}^{3} \\ x = 8 \\ x - 8 = 0$

The difference of sample means of two populations is 55.4, and the standard deviation of the difference of sample means is 28.1.

Doss [256]

Answer:

since if we are testing the null hypothesis at the 95% confidence level is that the difference of the two means is not significant at the 95% confidence level, so the null hypothesis must be rejected.

Hence option 3) is correct.

Find the prime factorization of following number. Write any repeated factors using exponents 624

DerKrebs [107]

Solution:

The number 624 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 624. The first step is to divide the number 624 with the smallest prime factor, here it is 2. We keep dividing until it gives a non-zero remainder.

624 ÷ 2 = 312

312 ÷ 2 = 156

156 ÷ 2 = 78

78 ÷ 2 = 39

Further dividing 39 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 39 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.

Then, the prime factors of 624 are 2, 3, 13, and we have that the prime factorization of 624 is:

$2^4\text{ }\cdot\text{ }3^1\cdot13^{1^{}}$

So that, we can conclude that the solution is:

$2^4\text{ }\cdot\text{ }3^1\cdot13^{1^{}}$
