An American roulette wheel has 38 spaces, labeled using the numerals 1​ through 36​​, 0​, and 00. In a random spin of the wheel, what is the probability that the ball will land on 2?

Answers

Answer 1
Answer:  1/38

This is because there's one space labeled "2" out of 38 spaces total.

This fraction is approximately equal to 1/38 = 0.0263 meaning there's roughly a 2.63% chance of landing on this space.

Answer 2

The probability is 0.0263 that the ball will land on 2 in a random spin of the wheel.

What is probability?

The probability is defined as the possibility of an event is equal to the ratio of the number of outcomes and the total number of outcomes.

Assuming an unbiased wheel.

The probability of an event = number of favourable outcomes/ number of total outcomes.

The total number of outcomes is 38

The number of favourable outcomes is one because there's one space labeled "2" out of 38 spaces total.

The probability of an event = 1/38 = 0.0263

Hence, the probability is 0.0263 that the ball will land on 2 in a random spin of the wheel.

well, hmmm to check for polar symmetry, hmmm say we simply replace the value for either "r" or "θ" or both in the original equation, if the equation rendered is the same as the original, there you have it, symmetry, so let's do that.

Type the price of one box of candy here.


How much would 2 large buckets of popcorn cost?

How much would 3 boxes of candy cost?


How much would 2 large buckets of popcorn and 3 boxes of candy cost?

Answers

Answer:

One bucket of popcorn:  6$

One box of candy: $3.75

2 buckets of popcorn:  $12

3 boxes of candy:  $11.25

2 buckets of popcorn and 3 boxes of candy:  $23.25

Step-by-step explanation:

We can find the cost of one bucket of popcorn and one box of candy using a system of equations

[tex]4P + 6C=46.50\\P + C =9.75[/tex]

We can use the elimination method and thus multiply the second equation by -4:  

[tex]4P + 6C = 46.50\\-4(P+C=9.75)\\\\4P + 6C = 46.50\\-4P -4C=-39\\\\2C = 7.5\\\\C = 3.75[/tex]

We can plug C into the second equation to find P:

[tex]P + 3.75 = 9.75\\P = 6[/tex]

Thus, the cost of two buckets of popcorn is 6 * 2 = $12

And the cost of three boxes of candy is 3.75 * 3 = $11.25

And the cost of both two buckets of popcorn and three boxes of candy is (6*2) + (3*3.75) = 12 + 11.25 = $23.25

Answer:

See below ↓

Step-by-step explanation:

Let's find the x and y values.

Step 1 : Equate the y expressions.

The two equations have given different values for yTherefore by equating them, we can solve for x2x - 5 = -2/3x + 3

Step 2 : Convert fractions in the equation to whole numbers.

The value -2/3 is a fractionWe can make it a whole number if multiply throughout by the value of its denominator ⇒ 33(2x - 5) = 3(-2/3x + 3)6x - 15 = -2x + 9

Step 3 : Bring x terms to one side and constant terms to the other.

6x + 2x = 9 + 158x = 24x = 3

Step 4 : Solve for y by plugging the value of x into one of the given equations.

y = 2(3) - 5y = 6 - 5y = 1

Describe and correct the error in using the percent proportion to answer the question below
“6 is 6.25% of what number”

Answers

Using proportions, it is found that the error was treating the 100% value as a percent(100) instead of a decimal 1, hence the correct value is of 96.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, we have that 100% = 1 of the number is w, while 6 is equals to 6.25% = 0.0625. Hence the rule of three is given by:

1 - w

0.0625 - 6

Applying cross multiplication:

0.0625w = 6.

w = 6/0.0625

w = 96.

The error was treating the 100% value as a percent(100) instead of a decimal 1, hence the correct value is of 96.

Find the x- and y-intercepts of y=−x/2−1.

Answers

Step-by-step explanation:

y = -x/2 - 1

the y-intercept is right there : -1.

it is the y-value when x = 0

the point of y-intercept is therefore (0, -1).

the x-intercept is the other way around. it is the x- value when y = 0.

0 = -x/2 - 1

1 = -x/2

-2 = x

the point of x-intercept is therefore (-2, 0)

Consider the graph of the quadratic function. Which
interval on the x-axis has a negative rate of change?
-2 to -1
-1.5 to 0
0 to 1
1 to 2.5

Answers

The only interval with a negative rate of change is the last one:

[1, 2.5]

When the rate of change is negative?

For an interval (a, b) and a function f(x), the rate of change is defined as:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

So the rate of change is only negative when the function evaluated on the first value of the interval is larger than the function evaluated in the second one.

For example, on the interval [1, 2.5} we can see that:

f(1) = 3

f(2.5) = -1

Then on this interval, the rate of change will be negative, meaning that this is the correct option.
