2. What percent of rolling a 2 3 probability of getting HH

faust18 [17]

Answer:

2. The correct answer option is 25%.

3. The experimental probability is 3% greater than the theoretical probability.

Step-by-step explanation:

2. We are given that a number cube is rolled 20 times out of which 5 times it lands on the number 2.

We are to find the experimental probability of getting the number 2.

P (2) = $\frac{5}{20} \times 100 =\frac{1}{4} \times 100$ = 25%

3. The theoretical Outcomes are: HH HT TH TT

So theoretical probability of getting HH = $\frac{1}{4} \times 100$ = 25%

Total number of outcomes = $28+22+34+16$ = 100

So experimental probability of getting HH = $\frac{28}{100} \times 100$ = 28%

Therefore, the experimental probability is 3% greater than the theoretical probability.

Find the value of x, for which : (81) -4 ÷ (729) 2-x = 9 /4x

tamaranim1 [39]

Answer:

$\huge{x = \frac{236164}{9477} = 24 \frac{8716}{9477}}$

Step-by-step explanation:

$(81) - 4 \div (729)2 - x = \frac{9}{4} x$

$81 - \frac{4}{729} \times 2 - x = \frac{9}{4} x$

$81 - \frac{8}{729} - x = \frac{9}{4} x$

$\frac{59041}{729} - x = \frac{9}{4} x$

$236164 - 2916x = 6561x$

$- 2916x - 6561x = - 236164$

$- 9477x = - 236164$

$\boxed{\green{x = \frac{236164}{9477} = 24 \frac{8716}{9477}}}$

Area and explanation?

Olin [163]

There are a few ways to go about doing this, but the easiest is portably to break it up into three shapes: two identical triangles, and a rectangle. The area of one triangle is:
1/2 (10x8) = 40, so the area of two triangles is 80.

The area of the square is 20 x 8, which is 160.

The total area is the sum of the two:
80 + 160 = 240, and this is your total area.
