A coin is flipped 150 times. The results of the experiment are shown in the following table:

1 answer:

8 0

The answer is C because theoretically it should have a 50% of landing heads but instead it lands heads 56% of the time. Thus this is 6% higher than 50%. It's not D because there is not specified detail of how the person got this data so you can assume that the person did a fair survey/data collection.

Answer:

circumference=>2πr

circumference= 119.32 cm

π = 3.14

r =?

119.32 = 2 × 3.14 × r

r = 119.32/6.28

r = 19 cm

so area = πr²

area = 3.14 × (19)²

area = 3.14 × 361

area = 1,133.54 cm²

Answer:

Parallel
Neither parallel nor perpendicular
Perpendicular

Step-by-step explanation:

<u>Given line m:</u>

y = 4/5x - 3

<u>Relationship of line m with following lines:</u>

1.<u> y = 4/5x + 3</u>

Same slope, different y-intercept
Parallel

2. <u>y = -4/5x + 3</u>

Slope are negative, different y-intercept
Neither parallel nor perpendicular

3. <u>y = - 5/4x + 3</u>

Slopes are negative-reciprocal, different y-intercept
Perpendicular

2. The table below shows that the distance d varies directly as the time t. Find the constant of variation and the equation which describes the relation.

<h2><u>Solution</u>:-</h2>

Since the distance d varies directly as the time t, then d = kt.

Using one of the pairs of values, (2, 20), from the table, substitute the values of d and t in d = kt and solve for k.

$\sf{\rightarrow{d = kt}}$
