The price of a box of candy will be $1.25.

Expression in math's is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

Tiffany gets $25 and 1 box of candy.

And, Todd gets $20 and 5 boxes of candy.

Now,

Since, Tiffany gets $25 and 1 box of candy.

And, Todd gets $20 and 5 boxes of candy.

Let price of box of candy = x

So, We can formulate;

⇒ $25 + x = $20 + 5x

Solve for x as;

⇒ $25 - $20 = 5x - x

⇒ $5 = 4x

⇒ x = 5/4

⇒ x = $1.25

Thus, The price of a box of candy = $1.25

What is binomial distribution?

A popular probability distribution known as the binomial distribution simulates the likelihood of getting one of two outcomes given a set of parameters. It totals the number of trials when each trial has an equal chance of producing a particular result. By dividing the quantity of independent trials by the number of successes, one can calculate the value of a binomial.

Let X has binomial distribution with n = 15 and  p = 0.20

The PDF of the distribution can be written as:

P(X=x)  = nCx(p)x (1-p)n-x

Probability for 0 patients have broken bones can be calculated as:

P(x=0) = 15C0(0.20)0 (1-0.20)15-0

P(x=0)  = 0.035184 = 0.0352

Therefore, the probability is  0.0352

Answer: 7.7%

Step-by-step explanation:

So the answer is 7.7

To find the percent error, start by listing the key information from the problem.

Greta's scale shows the package weighing 3 pounds.

The scale at the post office shows the package weighing 3.25 pounds.

First, find the amount of error. It is the difference between 3.25 and 3, which is 0.25.

Now, use the formula to find the percent error.

percent error =

amount of error

correct amount = 0.25

3.25

= 0.0769…

You can rewrite this as a percent rounded to the tenths place, 7.7%. So, the percent error for Greta's scale measurement is about 7.7

Step-by-step explanation:

multiples of 8 = 1,2,4,8

multiples of 12= 1,2,3,4,6,12

Step-by-step explanation:

Give the slope between the points (-5,-2)(-2,-7)

slope = change in y / change in x

slope = (-2 - (-7)) / (-5 - (-2))

slope = ( -2 + 7) / ( -5 + 2)

slope = 5/-3

slope = -5/3 or -1.667

Having a rectangular pasture for the animals to graze in is something a farmer wants in order to start growing cows, horses, goats, and sheep. She has decided to purchase 7500 ft of fencing. 1875 square feet is the maximum possible area that each of the four pens will enclose.

The maximum possible area of each pen is 1875 square feet. To calculate this, first calculate the total area of the large rectangle that the farmer is enclosing. To do this, multiply the total length of the fencing (7500 feet) by the width of the fence (1 foot). This gives us 7500 square feet as the area of the large rectangle.

Next, divide the area of the large rectangle by 4 to get the area of each pen. This gives us 1875 square feet as the maximum area of each pen.

Total Area of Large Rectangle = 7500 ft x 1 ft = 7500 sq ft

Area of Each Pen = 7500 sq ft / 4 = 1875 sq ft

b) Velocity is the shaded region.

c) the area under curve b is greater than the area under curve a.

a) The total distance  represented by the shaded region A, the area under the graph of v(t).

(c) A is a triangle, so its area is

b) The meaning of area of the shaded region in this problem is: Velocity

Velocity is the directional velocity of a moving object as an indicator of the rate of change of position, observed from a certain frame of reference and measured at a certain time reference (eg 60 km/h northward).

c) The distance travelled will be represented by the area

What is radioactive decay?

The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive.

Here,

The half-life of the reaction is defined as the time required by a substance to reach half its initial concentration. It is represented by t(1/2)

 All radioactive decay processes follow the first-order reaction.

The equation for the half-life for first-order reaction follows:

t(1/2) = 0.693/k....(1)

where,

k = rate constant of a first-order reaction

Given value:

t(1/2) = 5715 years

Put the value of t in equation (1), and we get

k = 0.693/5715

k = 1.21×10⁻⁴yr

The integrated rate law expression for first-order reaction follows:

t = 2.303/k×㏒(a/(a-x))

where,

t = time period

a = initial concentration of the reactant = 58.2 counts per minute

(a-x) = Concentration of reactant left after time t = 38.0 counts per minute

k = rate constant of a first-order reaction

Put the values in the equation and we get

t = 2.303/1.21×10⁻⁴㏒58.2/38

t = 3523.77 years.

Hence, the age of the artifact is 3523.77 years.

To find the height of a regular tetrahedron, you can use the formula h = sqrt(2/3) * s, where h is the height of the tetrahedron and s is the length of one of its edges. In this case, the length of one of the edges is 6 inches, so plugging this value into the formula gives:

h = sqrt(2/3) * 6 inches

= sqrt(4/3) inches

= sqrt(4/3) * sqrt(1/1) inches

= 2/sqrt(3) inches

To convert this to a decimal and round to the nearest hundredth, we can use a calculator to find that the height of the tetrahedron is approximately 3.46 inches.

Let's find the answer to the first question

Take 355 divided by 250, then times 100% = 142%

142% - 100% = 42% increase

So the percent increase is 42%

Now let's find the answer to the second question

First, find the total cost by 355 + 50 = $405

that there is no smallest positive rational number is proven below.

What is Rational Number?

Numbers that may be expressed in the form p/q, where p and q are integers and q0, are considered rational numbers. Because fractions cannot have a negative numerator or denominator, they differ from rational numbers in this respect. Because of this, the numerator and denominator of a fraction are whole numbers (denominator 0), unlike in the case of rational numbers, when they are both integers.

So to convert a fractional to reduce form we have to divide by 10 to power how many digits thereafter decimal point, and make sure that numerator or denominator doesn't have commonly divisible.

Let r be any reasonable number.

We can infer that r/2 is rational because r is a rational number.

There is no smallest rational number so we can assume that r/2 r because r/2 is rational.

Hence, proved that here is no smallest positive rational number.
