Brian flips a fair coin 3 times. What is the probability of getting 3 heads?

earnstyle [38]

If Brain flips a coin 3 times the probability of getting 3 heads is 0.125.

The given statement is Brian flips a fair coin 3 times.

We need to find the probability of getting 3 heads.

<h3>What is probability?</h3>

Probability refers to possibility. A random event's occurrence is the subject of this field of mathematics. The range of the value is 0 to 1.

The possible outcomes are {HHH, THH, HTH, HHT, TTH, THT, HTT, TTT}.

Total number of outcomes = 8

The number of favourable outcomes =1

So, the probability of getting 3 heads = 1/8 = 0.125

Hence, if Brain flips a coin 3 times the probability of getting 3 heads is 0.125.

The school band has a goal of raising $800 for some new uniforms. If they have raised $512 so far, what percent of their goal ha

just olya [345]

Answer: 64%

Step-by-step explanation:

The band needs $800 for new uniforms and of that, they only raised $512.

Set up a proportion $\frac{part}{total} = \frac{percentage}{100}$ and plug everything you know in.

$\frac{512}{800}$ = $\frac{x}{100}$

Solve for x by cross multiplying and dividing.

512 × 100 = 51200

51200 ÷ 800 = 64

x = 64

The school band has raised 64% of their goal already.

Answer:

The area of the pentagon is = 31.5

Step-by-step explanation:

First, we determine the perimeter of the "Pentagon" drawn in the attachment:

$p=4+4+4+4.5+4.5=21$

Now, we'll check the formula for pentagons:

$a=\frac{perimeter x apothem}{2}$

we calculate the apothem by placing a 90° angle in one of the sides of the shape. It is equal to:

apothem=3

then, we can substitute the values in the formula

$a=\frac{21(perimeter) x 3(apothem)}{2} =\frac{63}{2} =31 \frac{1}{2} or 31.5$
