Answer: 2/5

Step-by-step explanation: The total number of letters available to choose from is 10. You want to know the probability of 4 of those 10. So you divide 4/10. When you simplify that fraction it becomes 2/5.

The solution is 2/5

The probability of choosing a letter from Q to T is given by the equation

A = 2/5

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability of choosing a letter from Q to T be represented as A

Now , the equation will be

Let the letters be represented as set 1 = { Q , R , S , T , U , V , W , X , Y , Z }

The total number of letters = 10 letters

The number of letters from Q to T = 4 letters

So , the probability of choosing a letter from Q to T is A = number of letters from Q to T / total number of letters

Substituting the values in the equation , we get

Probability of choosing a letter from Q to T is A = 4/10

On simplifying the equation , we get

Probability of choosing a letter from Q to T is A = 2/5

Therefore , the value of A is 2/5

Hence , the probability is 2/5

Step-by-step explanation:

Answer:

The answer is D

Step-by-step explanation:

It points out to find the height and it already gives you the volume and radius so all you have to do is plug in those to #'s.

So the "V" is always going to go first then the equal sign the the pi sign then a number followed by squared.

Right after that you should have an "H" which is the height you have to use to multiply.

It will take approximately 9.9 minutes until there are 2 grams of the element remaining.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

We can use the exponential decay formula to solve the problem.

The formula for exponential decay is:

[tex]A = A_0e^{-kt}[/tex]

where:

A₀ = initial amount

A = amount remaining after time t

k = decay rate constant

t = time

We can find the decay rate constant k using the given percentage decay per minute.

If the element decays by 27.5% per minute, then the decay rate constant is:

k = ln(1 - 0.275) = -0.3185

where ln is the natural logarithm.

Let's substitute the given values into the formula and solve for t:

[tex]2 = 120 e^{-0.3185t}[/tex]

Divide both sides by 120:

[tex]0.0167 = e^{-0.3185t}[/tex]

Take the natural logarithm of both sides:

ln(0.0167) = -0.3185t

t = ln(0.0167) / (-0.3185)

t ≈ 9.9 minutes (to the nearest tenth of a minute)

Therefore,

It will take approximately 9.9 minutes until there are 2 grams of the element remaining.

Answer:

A = (x + 25)(x + 15) - 30

Step-by-step explanation:

This question is not complete without a figure; find the figure attached.

Marissa is painting a regular patio with dimensions as

Length = (x + 25) units

Width = (x + 15) units

Area of this rectangular patio = Length × Width

Area = (x + 25)(x + 15) unit²

She has to paint the patio except the bench that does not need to be painted.

Dimensions of the rectangular bench,

Length = 10 units

Width = 3 units

Area of the bench = 10×3 = 30 units²

Area of the patio to be painted = Area of patio - Area of bench

Answer:

x+10=24

Step-by-step explanation:

the actual equation would give you 14

To represent the situation, you can use the equation x = 24 - 10 or the proportion x/24 = 10/24.

To represent the situation, we can use the equation: x = 24 - 10, where x represents the amount of water Mai drank. This equation represents the fact that the initial amount of water in the bottle (24 ounces) minus the amount of water that Mai drank (x ounces) equals the remaining amount of water (10 ounces).

Alternatively, we can also use the proportion x/24 = 10/24 to represent the situation. This proportion shows that the ratio of the amount of water Mai drank to the initial amount of water in the bottle is equal to the ratio of the remaining amount of water to the initial amount of water.
