The outside tempature dropped 20°F from the time arianna ate breakfast until the time she ate dinner. When she ate dinner the tempature was 35°F. Write and solve an equation to find the outside tempature t when arianna ate breakfast

Answers

Answer 1

The outside temperature t when Arianna ate breakfast was 55°F.

An equation is a mathematical statement showing that two expressions are equal. It is written with an equal sign (=) between two expressions, with one expression on the left side of the equal sign, and the other expression on the right side.

According to the given statements-  

Let the outside temperature at the time of breakfast be t°F.

The temperature dropped by 20°F by the time of dinner.

So the temperature at the time of breakfast = t - 20

Also, when she ate dinner the temperature was 35°F

So the equation for outside temperature t when Arianna ate breakfast will be -

t - 20 = 35

Simplifying we get,

t = 35 + 20

t = 55°F

Hence, the outside temperature t when Arianna ate breakfast was 55°F.

If 30 adult smartphone users are randomly selected, find the probability that exactly 19 of them use their smartphones in meeting or classes the probability is (Round to four decimal places as needed. ​

Answers

The probability of adults using smartphones in meetings or classes as per the randomly selected adults is equal to 0.3375.

Percent of randomly selected adults use smartphones in meetings or classes represents the probability of success 'p' = 37%

                                                                                 = 0.37

1 - p = 1 - 0.37

       = 0.63

Number of randomly selected adults use smartphone in meetings or classes represents sample size 'n'  = 30

Exactly 19 adults use smartphone represented by x

x = 19

Using binomial distribution :

Required probability is :

P(x) = ⁿCₓ× pˣ × ( 1 - p )ⁿ⁻ˣ

⇒P(x) = [ n! / x! (n - x)! ] × pˣ × ( 1 - p )ⁿ⁻ˣ

Substitute the values

⇒P(19) = [ 30! / 19! (30 - 19)! ] × 0.37¹⁹× ( 0.63 )³⁰⁻¹⁹

⇒P(19) = ( 30!/19! ×11! )  × 0.37¹⁹× ( 0.63 )¹¹

⇒P(19 ) = 0.3375

Therefore, the required probability of selecting exactly 19 adults who use their smartphones in meetings or classes is equal to 0.3375.

What are the domain and range of f (x) = -5/6 (x + 2)^2 - 8?

Answers

Answer:

Option B

Domain: all real numbers

Range [tex]f(x) \le -8[/tex]

Step-by-step explanation:

Given function is:
[tex]f\left(x\right)=-\dfrac{5}{6}\:\left(x\:+\:2\right)^2\:-\:8[/tex]

The domain is the set of all x values that result in a real and defined value for f(x).

The function has no undefined points and x is free to range from -∞ to +∞

So the domain is -∞ < x <∞ which is
All real numbers

The range is the set of all possible values for f(x) given a specific domain. In order to determine the range without too much hard work, let's first examine the function f(x)

The above function is the equation for a parabola.

Some things to note about a parabola equation:

The vertex form equation of a parabola is:
[tex]f(x) = a(x - h)^2 + k[/tex]
where the vertex is the point (h, k). So the x-value of the vertex = h and corresponding y-value is A vertex is the maximum or minimum point in the parabola If the coefficient a > 0 then the parabola opens upward and the vertex i(h, k) s a minimumIf the coefficient, a < 0 the parabola opens downward and the vertex (h, k) is a maximum

Let us compare the general vertex form equation of the parabola with the specific f(x) equation given

General Equation:    [tex]a (x - h)^2 + k[/tex]

This example:           [tex]-\dfrac{5}{6}\:\left(x\:+\:2\right)^2\:-\:8[/tex]

Comparing the similarity between the two equations we easily see that

[tex]\boxed{a = -\dfrac{5}{6}}[/tex]
This means the parabola opens downward and (h, k) represents a max point in the parabola

 


[tex]x - h = x + 2\\\\-h = 2\\\\h = -2\\[/tex]

[tex]k = -8[/tex]

So the vertex is at (-2, -8)

Since -8 is the maximum value for f(x), and the parabola extends to infinity on both sides, the range is :

[tex]\boxed{f(x) \le -8}[/tex]

Please answer!!! The inspector at a bottling plant checks 25 bottles. Two bottles do not pass inspection. All the bottles hold the same number of milliliters of sports drink

Answers

The equivalent expression for the amount of sports drinks that pass inspection is 23x milliliters.

The inspector at a bottling plant checks 25 bottles, and two bottles do not pass inspection.

To find the amount of sports drinks in milliliters that pass inspection, we can subtract the amount in the two bottles that do not pass inspection from the total amount in all 25 bottles.

Let x be the amount of sports drinks in milliliters in each bottle.

The expression for the milliliters of sports drink that pass inspection is = 25x - 2x

Now, simplifying the expression, we get,

25x - 2x = (25-2)x = 23x

The vertices of YEAR are Y(1,-4) E(3,0), A (-1,2) and R( -3,-2) . prove that YEAR is a Square

Answers

To prove that YEAR is a square, we need to show that all four sides have the same length and all four angles are right angles (90 degrees).

Side Lengths: To find the lengths of the sides, we can use the distance formula:

d = √((x2 - x1)² + (y2 - y1)²)

For example, to find the length of the side that connects Y and E, we can use the following calculation:

d = √((3 - 1)² + (0 - (-4))²) = √((2)² + (4)²) = √(4 + 16) = √20

We can use the same formula to calculate the lengths of the other sides. By doing so, we will find that the length of all four sides are the same, which is √20. This means that all four sides of YEAR are congruent, and therefore it is a square.

Answers

A graph that represents the overall equation represented by this scenario is shown in the image attached below.

How to determine the graph?

Based on the information provided about this company with respect to its same-day delivery and total number of miles to be covered, we would assign variables to the parameters as follows:

Let the variable x represent be the total number of miles.Let the variable y represent same-day delivery.

Next, we would translate the word problem into an algebraic equation by using an inequality:

Half the total number of miles = x/2.

y > x/2 - 3

Furthermore, we would determine the x- and y-intercepts as follows:

When x = 0, we have;

y = 0/2 - 3

y = -3.

Therefore, y-intercept = (0, -3).

For the x-intercept (y = 0), we have:

0 = x/2 - 3

Explain how your equation determines a linear measurement when the original equation determined a cubic measurement

Answers

The volume of a cone is V = πr²h/3

The equation rewritten to solve for the height is V = πr²h/3

How to determine the equation

It is important to note that the formula for volume of a cone is expressed as;

V = πr²h/3

The parameters are;

V is the volume of the coneπ takes the constant value, 22/7 or 3. 142h is the height of the cone

Since the ice cream fits inside the cone and the height still holds the ice cream, let's make the height subject of formula.

Let's take the following steps;

V = πr²h/3

cross multiply the equation, we get;

V × 3 =  πr²h × 1

Multiply the values

3V = πr²h

To make the variable 'h' stand alone, let's divide both sides of the equation by its coefficient

3V/πr² = πr²h/πr²

Divide the values

4. Physical punishments such as whipping or amputation are no longer used in most modern legal systems.

5. Fines and imprisonment are still used as punishments today.

6. Based on these short excerpts from the code, it seems that Hammurabi defined justice as a system of strict punishment for crimes, with different punishments for different classes of people and different severity of crimes.

Our codes of law today show similarities to the Code of Hammurabi in that they both have a system of punishment for crimes. However, there are also many differences, such as the fact that our legal system is considered more fair and equal, and places a greater emphasis on rehabilitation and protecting the rights of the accused.

7. Today's view of justice has changed significantly from Hammurabi's in that it places a greater emphasis on protecting the rights of the accused, rehabilitation, and equality before the law. This change can be attributed to a number of factors, including the development of democratic societies, the influence of human rights movements, and the advancement of legal scholarship and philosophy.

Answers

If in the first week of​ July, a record 1,120 people went to the local swimming pool. the percent decrease in the number of people who went to the pool over these four​ weeks is 10%.

How to find the percentage decrease?

First week:

Number of people went to the local swimming pool =1120
