Answer:

B

Step-by-step explanation:

$\frac{CD}{AD} =\frac{AD}{BD} $

AD^2=CD \cdot BD

AD=\sqrt{CD \cdot BD}

In this question, you are clearly supposed to use the geometric mean theorem or known as the right triangle altitude theorem. But note that there are other approaches to find the height of the triangle.

Using Pythagorean theorem:

AD^2+CD^2=AC^2 \Rightarrow AD=\sqrt{AC^2-CD^2}

Also,

AD=AC\sin(c)

Answer:

B. AD = sqrt(CD * BD)

Step-by-step explanation:

By the right triangle altitude theorem,

CD/AD = AD/BD

AD^2 = CD * BD

AD = sqrt(CD * BD)

Answer: B. AD = sqrt(CD * BD)

Notice that the alternative hypothesis is a two-tailed test. Suppose ttest_ind method from scipy module is used to perform the t
Korvikt [17]

Answer:

The <em>p</em>-value of the test is 0.0512.

Step-by-step explanation:

The <em>p</em>-value of a test is well-defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.

In this case the output of the t-test_ind method from scipy module is provided as follows:

Output = (-1.99, 0.0512)

The first value within the parentheses is the test statistic value.

So the test statistic value is, -1.99.

And the second value within the parentheses is the <em>p</em>-value of the test.

So the <em>p</em>-value of the test is 0.0512.

In the continental United States,the ratio of states that border an ocean is 7:9 .How many of the states border an ocean?
Delvig [45]
So, there are 48 states, let's divide them into 16 groups  (because 7+9=16)


48/16=3

so that means there are 16 groups of 3 states.

and those groups are in a ratio of 7:9, seven to 9 groups.

I assume that the 7 refers to the states that border an ocean, then the number of states will be 7*3=21

Use a negative factor to factor the expression -5g + 15h - 25
Firdavs [7]

Answer:

<h2>-5g + 15h - 25 = -5 × (g - h + 5)</h2>

Step-by-step explanation:

-5g = -5 × g

15h = 5 × 3h

-25 = -5 × 5

-5g + 15h - 25 =  -5 × g - (-5 × 3h) + (-5 × 5) = -5 × (g - h + 5)

the area of a rectangle banquet hall is 7400 square feet. the length of one side of the hall is 82 feet. explain how you can use
Vadim26 [7]
We are given that the hall has a rectangular shape.
Area of rectangle can be calculated using the following rule:
Area of rectangle = length * width

We are also given that:
Area = 7400 square feet
length = 82 feet

Substitute with the givens in the above equation to get the width as follows:
Area of rectangle = length * width
7400 = 82 * width
width = 7400 / 82
width = 90.24390244 feet

In a school building, there are 8 exterior doors and 12 stairways to enter the second floor. Find a total number of ways to reac
Kazeer [188]
To reach the second floor you would look at all ways to enter to building(8) and multiply it by the number of ways to reach the second floor (12).

8 x 12 = 96 possibilities

Think of it in groups.

1st door and 12 possible sets of steps
2nd door and 12 possible sets of steps
3rd door and 12 possible sets of steps
4th door and 12 possible sets of steps
5th door and ..., etc.....
