Eric needs to order programs for the next school football game. Only 1 out of 2 people will buy a program for the game. If there will be 900 people at the game and programs come in boxes of 50, how many boxes of programs should Eric order?

Answer:

you would start off with putting 520 over 100 and then you would simplify it down and it becomes 26/5

Answer:

15

Step-by-step explanation:

Mean value of the set = 4+10+14+18+22+22/6

= 15

By adding the mean value to a set, its mean wouldnt change. Therefore, 15 should be added to the set

Answer:

197

Step-by-step explanation:

kk here we go

find the area of each side so:

5 x 5 = 25

5 x 5 = 25

9 x 5 = 45

6.4 x 5 = 32

trapezoid = 5 + 9 = 14

and then divide that 14 by 2 which is 7. multiply by height which is 5 again

that equals 35

double that bc there are 2 trapezoids = 70

add all together

197

there ya go:)

Answer:

[tex]a_n= - 1( - 2)^{n-1}[/tex]

Step-by-step explanation:

The given geometric sequence is :

-1,2,-4,8,...

The first term is

[tex]a_1=-1[/tex]

The common ratio is

[tex]r = \frac{2}{ - 1} = - 2[/tex]

The nth term is given by;

[tex]a_n=a_1(r^{n-1})[/tex]

We substitute the values of the first term and common ratio to get:

[tex]a_n= - 1( - 2)^{n-1}[/tex]

This is called the explicit formula.

Answer:

19 units.

Step-by-step explanation:

Consider the below figure attached with this question.

From the below figure it is given that MN=PQ.

It is given that MP = 6x – 5, QR = 3x + 1, and RN = 6.

Since non parallel sides are equal, therefore it is an isosceles trapezoid.

The diagonals of an isosceles trapezoid are equal.

[tex]MP=QN[/tex]

[tex]MP=QR+RN[/tex]

Substitute the given values.

[tex]6x-5=3x+1+6[/tex]

[tex]6x-5=3x+7[/tex]

[tex]6x-3x=5+7[/tex]

[tex]3x=12[/tex]

[tex]x=4[/tex]

The value of x is 4.

[tex]QN=MP=6x-5=6(4)-5=24-5=19[/tex]

Hence, the measure of QN is 19 units.

To find QN,  RN from the value of QR which is 3x - 5

The value can be found using Algebraic expressions.

To find QN, we need to find the value of QR and subtract RN from it.

Given that QR = 3x + 1 and RN = 6, we can substitute these values into the equation.

So, QN = (3x + 1) - 6.

Simplifying further, QN

= 3x + 1 - 6

= 3x - 5.

Answer:

  look for places where the derivative is zero or undefined

Step-by-step explanation:

Find the derivative. Critical points are where the derivative is zero, and where it is undefined.

__

A polynomial function may or may not have points where the derivative is zero. It will never have points where the derivative is undefined (tangent lines are vertical).

A rational function, or one involving fractional exponents may have critical points where the derivative is undefined.

__

For example, the function ...

  y = √(1 -x^2)

has the derivative ...

  y' = -x/√(1 -x^2)

This has a zero at x=0 (tangent is horizontal). It is undefined at x = ±1, where the denominator is zero (tangent is vertical). Those values of x tell you the critical points are (-1, 0), (0, 1), (1, 0).

Critical points in a mathematical function are found by deriving the function, setting the derivative equal to zero, and solving for x. The x-values obtained are the x-coordinates of the critical points. An example is provided for the function f(x) = x3 - 3x2.

To find the critical points in a function, you first need to identify the derivative of the function. Once you have obtained the derivative, you set it equal to zero and solve for x. The x-values you get are the x-coordinates of your critical points.

Let's illustrate with an example, using the function f(x) = x3 - 3x2.

First, let's find the derivative, f'(x) = 3x2 - 6x. Then set f'(x) = 0 and solve for x. This gives us x = 0 and x = 2. Therefore, (0, f(0)) and (2, f(2)) are the critical points of the function.

Please note, critical points are also the points where the derivative is undefined. However, in this case the derivative exists for all real numbers, so we do not have any such critical points here.

Answer:

65 miles every 1 hour

Step-by-step explanation:

Unit rate is found once one of the units is 1. In this case we need to reduce the ratio so that it is 1 hour and we get a unit rate. We can do this by dividing both sided by 2 so that the hours are reduced to 1.

130=2

130/2=65                2/2=1

65=1

65 miles every hour

The unit rate of 130 miles per 2 hours is 65 miles per hour. This is calculated by dividing the number of miles (130) by the number of hours (2).

In Mathematics, the term unit rate refers to the ratio of two measurements, in which the denominator is 1. In this situation, you are given the rate of 130 miles per 2 hours and need to reduce it to a unit rate. To do this, you divide the number of miles (130) by the number of hours (2).

The calculation would be 130 miles ÷ 2 hours = 65 miles per hour. Hence, the unit rate of 130 miles per 2 hours is 65 miles per hour. This means that if you travel at this rate, you would cover 65 miles in one hour.

part B) The population in 25 years since 1970 will be one million seven hundred thousand people (1,700,000)

Step-by-step explanation:

The correct equation is

[tex]P(t)=54t+350[/tex]

Part A) what are t values when it is 1985 and 1990.

we have

[tex]P(t)=54t+350[/tex]

This is the linear equation in slope intercept form

where

P(t) ----> is the population, in thousands

t ---->  the time, in  years, since 1970

Remember that

t = 0 for 1970

so

For the year 1985

[tex]t=1985-1970=15\ years[/tex]

For the year 1990

[tex]t=1990-1970=205\ years[/tex]

Part B) what is p(t), when t=25?

For t=25 years

substitute the value of t in the linear equation

[tex]P(t)=54(25)+350=1,700[/tex]

Remember that the population is in thousands

That means

The population in 25 years since 1970 will be one million seven hundred thousand people (1,700,000)

Final answer:

An equivalent expression to 56m+21n is found by factoring out the greatest common divisor, which is 7, resulting in the simplified expression 7(8m + 3n).

Explanation:

The question asks for an equivalent expression to 56m+21n. To find an equivalent expression, we look for common factors that both terms in the expression have. In this case, both 56 and 21 are divisible by 7. Therefore, we can factor out 7 from both terms to simplify the expression.

The factored form of the expression is:

7(8m + 3n)

This shows that 7(8m + 3n) is an equivalent expression to 56m+21n, simplifying the original expression by finding common factors.

Answer:

D.1/64

B.1 in 12

A.64%

Step-by-step explanation:

Each dial has 4 letters and only one of them is correct; the probability to choose the correct one is then 1/4. Selecting a letter in each dial is independent, then the probability of guessing the right combination in one try is 1/4 * 1/4 * 1/4 = 1/64

8% means a probability of 8/100 or an odds of 8 in 100. Dividing each term by 8 we get 8/8 = 1 in 100/8 = 12.5, which can be rounded to 1 in 12

80% means a probability of 80/100 = 0.8. Given that the 2 free-throws are independent, the probability that he makes both is 0.8*0.8 = 0.64 or 64%

Adding two negative fractions follows the same principle as adding two negative integers: simply add the absolute values and apply a negative sign to the result. Understanding the basic rules of addition such as 'minus a minus makes a plus' helps with this process. This principle is consistent across various types of numbers, including complex numbers and vectors.

Adding two negative fractions is similar to adding two negative integers because in both cases, the sum will also be negative. Just like adding negative integers, when adding negative fractions, one simply adds the absolute values of the numerators while keeping the common denominator and then assigns a negative sign to the result. For instance, adding −½ and −¼, first find a common denominator (let's say 4), which turns the fractions into −1/4 and −2/4, then add the numerators to get −3/4, maintaining the negative sign.

Understanding the basic rules of number operations, such as the fact that when two positive numbers add, the sum has a positive sign, and when two negative numbers add, the sum has a negative sign, assists our intuition in addressing both negative integers and negative fractions. Similarly, subtraction of fractions follows the same principle as integers: by changing the sign of the number to be subtracted and then adding as per the normal rules.

The same principles used for addition of integers apply to the addition of negative fractions, showing that basic arithmetic operations are consistent across different types of numbers. This consistency extends beyond integers and fractions, as observed in complex numbers and vector addition, which also follow similar addition rules by combining the respective parts separately.
