Answer:

0.06 = 6% probability of landing open side up.

0.14 = 14% probability of landing closed side up.

0.8 = 80% probability of landing on its side.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes. For an experimental probability, these numbers are taken from previous trials.

Landing open side up:

3 out of 50, so:

$p = \frac{3}{50} = 0.06$

0.06 = 6% probability of landing open side up.

Landing closed side up:

7 out of 50, so:

$p = \frac{7}{50} = 0.14$

0.14 = 14% probability of landing closed side up.

Landing on its side:

40 out of 50, so:

$p = \frac{40}{50} = 0.8$

0.8 = 80% probability of landing on its side.

Name the property that justifies the given statement 2x_2y=2(x_y)

Gemiola [76]

Answer:

Distributive property

Step-by-step explanation:

With the distributive property, it is possible to simplify expressions that consist of an expression term such as (a + b) being multiplied by one singular term such as c given as follows

c ×(a + b) = c·a + c·b

Factoring, which is the reverse use of the distributive property enables the difference or the sum of two products, each having a common factor to be the presented as the difference or the sum of two numbers multiplied by the common factor as follows;

2·x - 2·y = 2·(x - y).

Given △ABC, AB=15, BD=9, AD ⊥ BC , m∠C=30° Find: The perimeter of △ABC.

Ann [662]

Answer:

48 + 12√3 units

Step-by-step explanation:

ALL LENGTHS MUST BE POSITIVE (I did this to avoid writing ± and showing that only + works)

1. Find AD (you'll find why later): 15² = 9² + AD² --> AD² = 144 --> AD = 12

2. 30-60-90: 12-DC-AC --> AC = 24, DC = 12√3 (side opposite of 90 is double side opposite of 30, side opposite of 60 is √3 times the opposite of 30)

P = AB + BD + DC + AC = 15 + 9 + 12√3 + 24 = 48 + 12√3 units

What are the coordinates of the vertex of the graph of f(x)=2|x−3|f(x)=2|x−3|? Enter your answer as an ordered pair without pare

melomori [17]

Function is always positive, except for f(x)=0. Therefore, f(x)=0 is the vertex.

$f(x)=0
\\2|x+3|=0
\\|x+3|=0
\\x+3=0
\\x=-3$

The vertex is at (-3,0).
