It all depends what value they use for pi 3.14 or 22/7 or just pi on the calculator.

I used 3.14 and got 2.135.2

2(3.24)(10)^2+2(3.14)(10)(24)

The theoretical probability is the probability you'd expect before performing the experiment. So, assuming the die is fair, every outcome has the same probability. Since there are 6 numbers on the die, every number appears, theoretically, with probability 1/6.

The experimental probability is the probability you estimate after performing the experiment. You divide the number of cases a certain outcome happened, and divide by the total number of trials.

In this case, you performed 50 rolls, and the die landed on six 12 times. This means that the experimental probability is 12/50, or 6/25.

a flat for sale sign has a perimeter of 58 inches. the length is 5 inches longer than the width. what is the width?

timofeeve [1]

Answer:

25 inches

Step-by-step explanation:

1. Information that is needed to solve the problem;

The formula for the perimeter is:

2(a+b) = P

where "a" is the length and "b" is the width.

2. Solving the problem;

Substitute the given values into the formula;

2( 5 + b ) = 58

Inverse operations;

2 ( 5 + b ) = 58

/2 /2

5 + b = 29

-5 -5

b = 25

Can someone show me how to do this ? please :)) will award brainliest

sveticcg [70]

Answer:

x=16

Step-by-step explanation:

Because of Thales Intercept Theorem, AN/NG=NE/GL

NE/GL=1/2, AG=2x-9+x+7=3x-2

2x-9/3x-2=1/2

x=16

Each lenght is in metres Calculate DC

Gnom [1K]

Step-by-step explanation:

ED is greater than BC

the line from B to ED ^ (which i drew ) the point it touches ED name it X. so EX will be 2 ( ED-BC)(6-4).

then u have a triangle. EX, XB and EB.

you have length of EX(2) and u have hypotenuse. so u can calculate XB using Pythagoras theorem.

15.1²=2²+XB²

15.1²-2²=XB²

224.01=XB²

XB=14.97

since XB and DC are parallel ( a rectangle is forming XBCD) so DC is also 14.97

Use the description and table to graph the function, and determine the domain and range of f(x). Represent the domain and range

zmey [24]

The domain of the function is x > 0 and the range of the function is -∞ < f(x) < ∞

<h3>How to determine the domain?</h3>

The table represents a logarithmic function.

The domain represents the set of x values.

From the table, we can see that all the x values are positive values i.e. x > 0

Hence, the domain of the function is x > 0

<h3>How to determine the range?</h3>

From the table, the table outputs all zero, positive and negative numbers

This means that the range is the set of all real numbers.

Hence, the range of the function is -∞ < f(x) < ∞
