A fair die is rolled 5 times. What is the probability of having no 1 and no 2 among the rolls

Answer:

Where is the statement?

Step-by-step explanation:

The 2 equations will have infinitely many solutions if k equals 10.

Here we have

10x + 5y − (k−5) = 0 and 20x + 10y − k = 0

Since these 2 are already in the standard form

a₁x + b₁y + c₁ = 0

and

a₂x + b₂y + c₂ = 0

we don't have to make any changes to them

According to the law, an equation has infinitely many solutions if

a₁/a₂ = b₁/b₂ = c₁/c₂

here,

a₁ = 10,  b₁ = 5, and c₁ = - k + 5

and,

a₂ = 20, b₂ = 10, and c₂ = - k

Hence, we get

10/20 = 5/10 = ( - k + 5)/(-k)

or, (k - 5)/k = 1/2

or, 2k - 10 = k

or, k = 10

Hence the 2 equations will have infinitely many solutions if k is equal to 10.

A fruit bouquet artist charges $1.50 for each piece of fruit in a bouquet, x, plus an additional $17 for the basket and decorations. Customers receive free delivery when their order is over $40.

Step-by-step explanation:

$1.50 represents the cost of each piece of fruit, but we don't know how many fruits are included in the basket, so let x be the number of fruit. That total must be added to the cost of the basket.

If consumers receive free delivery for orders over $40, then 17+1.50x must be greater than $40.

The element will be gone in approximately 10.9 minutes.

We can calculate this by using the formula:

Time = (log(Initial mass / Final mass)) / (log(1 - decay rate))

Time = (log(300 / 110)) / (log(1 - 0.054))

Time = 10.9 (rounded to the nearest tenth of a minute)

Therefore, The element will be gone in approximately 10.9 minutes.

Using the given information, we can calculate the z-score as z = (56.4 - 67.6) / 3.5, which gives us a z-score of -2.3. This means that 2.3 standard deviations below the mean of adult men's heights is the doorway height of 56.4 inches. Since the area under the normal curve from -∞ to -2.3 is 16%, this means that 84% of adult men can fit through the door without bending.

Using the given information and the desired percentage, we can calculate the z-score as z = (x - 67.6) / 3.5, where x is the doorway height. Solving for x, we get x = 57.6 inches. Therefore, a doorway height of 57.6 inches would allow 40% of adult men to fit through without bending.

A parabola is a mathematical curve that is symmetrical in shape and is often described as an upside-down U. It is a two-dimensional, closed curve and is an important part of conic section geometry. A parabola has a single vertex, which is the highest or lowest point of the parabola. It can also be thought of as the focus of the parabola.

For a quadratic of the form px^2 + 40x + 16 to be a perfect square, it must be able to be written in the form (mx + n)^2 for some real numbers m and n.

Expanding (mx + n)^2 gives:

(mx + n)^2 = m^2x^2 + 2mnx + n^2

Comparing this to the given quadratic, we can see that:

m^2 = p

2mn = 40

n^2 = 16

Solving for m and n, we find that:

m = ±√p

n = ±4

Therefore, in order for the quadratic to be a perfect square, the square root of p must be rational, and the value of p must be one of the following:

p = 0, 1, 16

So the possible values of p that make the quadratic a perfect square are 0, 1, 16.

The difference between the largest 8-digit number and the smallest 7-digit number is 98999999.

The aim is to find the smallest 7-digit and largest 8-digit numbers, and then we need to determine the difference between these two values.

Let's start by finding the smallest 7-digit number.

We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit; that is, 1 therefore it  can be used in the highest place value.

Thus, we can create the required 7-digit smallest number with 0 and 1.

Hence, the smallest 7-digit number is 1000000.

Now, we will discover the largest 8-digit number.

As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 8-digit number with the digit 9.

Thus, the largest 8-digit number is 99999999.

Now, find the difference between these two values.

So, we can determine the difference between the smallest 7-digit and the largest 8-digit numbers by subtracting the smallest from the largest.

Thus, we get,

⇒99999999−1000000

⇒98999999

Hence, 98999999 is the difference between the smallest 7-digit and the largest 8-digit numbers.

The value for a in quadratic function a(x-1)²+3 is obtained as a = 2.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The vertex of the quadratic function is (1,3).

The line passes through the points (3,5).

The equation is in the form - a(x-1)²+3

It is known that the vertex form of a quadratic function is f(x) = a(x-h)² + k, where (h,k) is the vertex of the parabola.

So it can be written -

f(x) = a(x-1)² + 3

Substitute the value of (1,3).

f(1) = a(1-1)² + 3 = 3

And for the point (3,5) the equation will be -

f(3) = a(3-1)² + 3 = 5

Set up a system of equations -

a(1-1)² + 3 = 3

a(3-1)² + 3 = 5

Solving for a in these equations -

a = 2

Therefore, the value of a is obtained as 2.

Step-by-step explanation:

Answer:

How do you calculate grams per 100mL concentration?

The concentration is the amount divided by the volume it is dissolved in. For example you might dissolve 0.9g of sodium chloride in 100mL of water. Sometimes this is referred to as 0.9% w/v since it is 0.9g weight divided by 100mL volume and “w/v” stands for weight per volume.”

Solubility≡62.5⋅g⋅100⋅mL−1..

Explanation:

☯We want Concentration=Mass of solute100 mL volume of solvent.

We make the reasonable assumption that the volume of solution is equal to 40⋅mL.

And so we set up the quotient.

25⋅g(40100)⋅mL=

☯In order to answer this question, you'll want to make use of the fact that pure water under standard conditions has a density of 1 g/ml. This means that 50 ml of pure water would have a mass of 50 grams. Therefore, we know that our sample has a 25 grams of sugar, in order for the total mass to be 75 grams.

☯The question doesn't specify what unit of concentration they prefer, so you can use the easiest, which is (mass of solute)/(volume of solvent) which in this case is 25g/50ml or .5 g/ml. If you need to write this in terms of molarity, you can use the molar mass of sugar to convert the 25g into moles and divide by .05 L, as molarity is given by (moles of solute)/(volume of solvent in liters).

☯Sugar solutions or "syrups" are used extensively in canning, and sometimes referred to as "heavy" or "light" syrups.

The terms heavy and light are commonly used in two different ways. We refer to weight when we say that an adult is heavier than a child. On the other hand, something else is alluded to when we say that one syrup is heavier than another. A teaspoon of heavy syrup would obviously weigh less than a gallon of light syrup, but heavy syrup is heavier in the sense that a given volume weighs more than the same volume of light syrup. It's interesting that a given volume of "heavy cream" actually weighs less than "light cream" (in this case, "heavy" refers to the thickness, or percent milk fat).

In "Molecular Gastronomy", Herve This (pronounced Thees) points out[2] that more precision is needed in canning recipes. Some call a heavy syrup 1 cup sugar to 2 cups water (a ratio of 0.5:1) while others refer to a medium syrup as 3-1/4 c sugar to 5 c water (a ratio of 0.65:1). The latter is actually heavier, or denser. Which is better for canning?
