The relative frequency of Event A in an experiment is 13.

Mathematics

Maru [420]2 years ago
5 0

Based on the relative frequency and the number of times the experiment is to be performed, the number of times Event A should occur is 10 times.

<h3>How many times should Event A occur?</h3>

The relative frequency in this regard is 1/3.

The number of times it will occur can be found as:

= Relative frequency x Number of times event was performed

Solving gives:

= 1/ 3 x 30

= 10 times

If f(x)= 10 sin(x) – 3 then f (30%) = ?
marissa [1.9K]

Answer:

The value of f(30) is equal to 2.

Step-by-step explanation:

The given expression is :

f(x)= 10 \sin(x) - 3

We need to find the value of f(30)

Put x = 30 in above expression.

So,

f(x)= 10 \sin(30) - 3\\\\=10\times \dfrac{1}{2}-3\\\\=5-3\\\\=2

Hence, the value of f(30) is equal to 2.

Help please. (right now i’m just filling in for the 20 characters it’s not relevant to the question)
suter [353]

Answer:

9

Step-by-step explanation:

We're using the Pythagorean theorem here since it's a right triangle.

a^2 (side) + b^2 (side) = c^2 (hypotenuse)

12 = a

x = b

15 = c

12^2 + b^2 = 15^2

144 + b^2 = 225

- 144             - 144 (subtracting 144 from both sides to isolate b)

b^2 = 81

\sqrt{b^2} = \sqrt{81} (getting rid of the exponent by squaring both sides)

b = 9

x = 9

Lerok [7]

Answer: No. The method is not fair.

 

<span>The probability of pulling a gold or a silver for the first time is 1/10. The probability of getting the same color the second time is 1/9. The probability of getting a different color on the second pullout is still 1/10. Therefore, the chance that same  colors will be pulled out is higher than that of different colors.  Betty  has an advantage in the drawing by 1.1%.</span>

 

Solution:

Probability of same color:

1/10+1/9

9/90+10/90

21.1%

Probability of different colors

1/10+1/10

2/10

20%

<span>21.1%-20%=1.1%</span>
