Answer:

The correct answer is 6 hours.

Step-by-step explanation:

Let Mrs. Long rent the bounce house for x hours.

Fixed price to be charged is 145.

Per hour price of the bounce house is 35. Total price of x hours is 35x.

Thus total amount charged by the rentals is 145 + 35x.

Mrs. Long paid 355 in total.

∴ 145 + 35x = 355

⇒ 35x = 210

⇒ x = 6.

Thus Mrs. Long rented the bounce house for 6 hours.

Step-by-step explanation:

A null hypothesis is the common accepted fact that the researcher works to prove it wrong. In this case, the survey revealed that 76% of US adults admit they lie to their doctor about how often they exercise. This forms the null hypothesis.

The alternative hypothesis suggest that a new theory is happening unlike the original one.In this case,  Dr. Moffett believes the percentage seems high, so the alternative hypothesis is that the percentage is lower than 76%

Final answer:

To find the probability of getting at least 2 heads in three coin tosses, count the favorable outcomes (HHH, HHT, HTH, THH) and divide by the total outcomes. The probability is 4/8 or 1/2, which is 50%.

Explanation:

The question asks to calculate the probability of getting at least 2 heads when flipping a coin three times. The sample space for three coin tosses consists of 8 possible outcomes: {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}. To find the probability of getting at least 2 heads, we need to count the favorable outcomes which are: {HHH, HHT, HTH, THH}, and then divide this number by the total number of possible outcomes.

There are 4 favorable outcomes out of 8 possible, so the probability is 4/8 or 1/2. Therefore, the probability of obtaining at least 2 heads in three coin tosses is 0.5 or 50%.

Answer:

There are 2 cups in a pint is correct

The correct measurement statement is that there are 4 pints in a quart. This conclusion is derived from understanding the relationship between cups, pints, and quarts in the customary system of measurement.

The correct measurement statement among the options provided is that there are 4 pints in a quart. This is because, in the customary system of measurement, one quart (qt) is equivalent to two pints (pt), and a pint is equivalent to two cups (c). Therefore, the relationship among these units of measure can be summarized as follows:

Thus, when we compare cups, pints, and quarts, we establish that the conversion factors are essential for accurate measurement in different scenarios, whether it be for cooking or scientific measurements.

Answer:

More than 250 miles

Step-by-step explanation:

Rental cost of company A is $80 + $0.6 per mile driven and company B also has a rental cost of $30 + $0.8 per mile driven.

To find the moment when company A rental cost matches that of company B,we have to create an equation that is ideal for both parties.

80 +0.6x = 30 + 0.8x

Where x is the number of miles traveled by both trucks.

Simplifying the above equation, we have

0.2x = 50 divide both sides by 0.2

= 250 miles is when both rental cost matches .

Therefore, the number of miles needed to be driven so as the rental cost of company A to better company B should be more than 250 miles

To determine when renting a truck from Company A becomes cheaper than Company B, we set the cost equations for both companies equal and solve for the number of miles. In this case, Company A becomes the better deal when the truck is driven more than 250 miles in a day.

The cost of renting a truck from each company can be defined using linear equations: Company A's cost as $80+0.60x = y$ and Company B's cost as $30+0.80x = y$, where 'x' is the number of miles driven and 'y' is the total cost. To find out when Company A's cost is less than Company B's, we set the equations equal to each other and solve for 'x': $80+0.60x = $30+0.80x$. Simplifying this equation gives, $x = ((80-30)/(0.80-0.60))$, thus 'x' = 250. Therefore, for company A to be a better deal, the truck must be driven more than 250 miles in a day.

Answer:

El primer paso será darle un nombre a nuestras variables:

x= Numero de libros comprados inicialmente

y=Precio inicial de los libros

Ahora analizamos el enunciado,

Lorena ha comprado libros todos del mismo precio por valor de 120 €

x*y=120 € (1)

El librero le regala 3 libros por lo que en realidad cada libro que cuesta 2 € menos

(x+3)(y-2)=120€ (2)

Tenemos entonces dos ecuaciones con dos incógnitas, así que podemos resolver,

Despejamos en (1)

x=120/y

Sustituimos en (2)

(120/y +3)(y-2)=120

120 - 240/y + 3y -6 =120

3y-240/y =120-120+6

3y -240/y =6

y- 80/y=6

y²-80=6y

y²-6y-80=0

Resolvemos la ecuación de segundo grado

a=1

b=-6

c=-80

Aplicando la resolvente,

(6+- √36+320)/2

6+-√356/2

(6+-18,86)/2

Como el valor de y no puede ser negativo la unica respuesta válida será:

y=12,43

Cada libro le costo 12,43€

Sustituyendo en (1)

x=120/12,43

x=9,65 como no puede ser un número racional

x=9

Lorena ha comprado 9 libros

Ana originally bought 12 books.

Let's say Ana originally bought x books, each costing p euros.

The total cost of all the books is 120 euros, so we can write the equation:

x * p = 120

After the bookseller gives Ana 3 free books, the new total number of books she has is x + 3 and each book costs p - 2 euros.

The new total cost of all the books is still 120 euros, so we can write the equation:

(x + 3) * (p - 2) = 120

Simplifying this equation, we get:

px + 3p - 2x - 6 = 120

Combining like terms:

px - 2x + 3p - 6 = 120

Substituting the equation px = 120, we get:

120 - 2x + 3p - 6 = 120

Simplifying further:

3p - 2x - 6 = 0

Let's rewrite this equation:

3p - 2x = 6

When we substitute the equation px = 120 into this equation:

3p - 2(120/p) = 6

Simplifying:

3p - 240/p = 6

Multiplying through by p:

3p^2 - 240 = 6p

Rearranging:

3p^2 - 6p - 240 = 0

Using the quadratic formula to solve for p:

p = (-(-6) ± sqrt((-6)^2 - 4*3*(-240)))/2*3

p = (6 ± sqrt(36 + 2880))/6

p = (6 ± sqrt(2916))/6

p = (6 ± 54)/6

For the positive value of p:

p = (6 + 54)/6 = 60/6 = 10

Now, substituting p = 10 back into the equation px = 120:

10x = 120

x = 120/10 = 12

So, Ana originally bought 12 books.

The population of Leavetown after 100 years would be 111,17.5681.

Step-by-step explanation:

Given that,

Initial Population = I = 123,000

Decreasing Rate = r = 2.375 = 0.02375

We have to find the population after 100 years. So,

n = 100

The formula to calculate the population (P) after n years with a decreasing rate r is:

[tex]P = I (1-r)^{n}[/tex]

Now, put the values in this formula.

[tex]P = 123,000 (1-0.02375)^{100}[/tex]

[tex]P = 123,000 (0.97625)^{100}[/tex]

[tex]P = 11117.5681[/tex]

Hence, the population of Leavetown after 100 years would be 111,17.5681.

The answer is C

Because the sum of the angles are not up to 180

which makes way for other angles.

Option B, three side lengths measuring 7m, 10m, and 12m can create more than one triangle because there are multiple ways the sides can be oriented to create different internal angles, therefore creating multiple triangles.

The question is about constructing triangles from given dimensions and determining which sets of dimensions can create more than one triangle. In geometry, for a set of dimensions to produce more than one unique triangle, it must not fully determine the shape of the triangle. The axiom that the sum of the angles in a triangle is exactly 180 degrees is key to answering part of this question. Here are the evaluations based on the given options:

Upon evaluating the provided dimensions:

Therefore, the correct answer is B: Three sides measuring 7m, 10m, 12m can create more than one triangle.

Step-by-step explanation:

A TANGENT to a circle is a line, ray or segment in the plane of the circle that intersect the circle in exactly one point.

An tangent to a circle is a line, ray or segment in the plane of the circle that intersects the circle in exactly one point.

A circle is defined as a plane figure bounded by a single curved line, with every point on that line being equally distant from the center point. Tangents have a unique property where they touch the circle at precisely one point and are perpendicular to the radius drawn to the point of contact. This concept is fundamental to understanding circles and their geometric properties.

Step-by-step explanation:

Jones figures that the total number of thousands of miles that an auto can be driven before it would need to be junked is an exponential random variable with parameter 1/20. Smith has a used car that he claims has been driven only 10,000 miles. If Jones purchases the car, what is the probability that she would get at least 20,000 additional miles out of it?

Given that the total number of thousands of miles(X) that an auto can be driven

before it would need to be junked is an exponential random variable with parameter 1/20.

=> X ≅ Exponential(λ= 1/20)

=> f(x) = 1/20 * e^(-x/20) , 0 < x < ∞

=> F(X) = P{X < x} = 1 - e^(-x/20)

The probability that she would get at least 20,000 additional miles out of it.

P{X > 20} = 1-P{X < 20}

P{X > 20} = 1-(1 - e^(-20/20))

= e^(-1)

Answer:

20 meters

Step-by-step explanation:

Seeing the image attached, we can observe that there is a triangle formed by half of the chord of the arc, the radius (hypotenusa) and part of the radius (r-4). Using pythagoras theorem in this triangle, we have:

(r-4)^2 + 12^2 = r^2

r^2 - 8r + 16 + 144 = r^2

8r = 160

r = 20

So the radius of the circle that contains this arc is 20 meters.

Answer:

20 m

Step-by-step explanation:

radius 'r', half the chord, and dist from center to the chord  has formed a right angle triangle

where,

r  is hypotenuse

(r-4) = one side i.e dist from center to chord)

12 = other side i.e half the length of the chord)

By applying Pythagoras theorem, we will have

r² = 12² + (r-4)²

 r²= 144 + r² - 8r + 16  --->(cancel out r²)

0 = -8r + 160

8r = 160

r = 160/8

r = 20 m

Thus, the radius of the circle containing this arc  is 20m

You can also verify this :

distance from center to chord: 20 - 4 = 16

r = [tex]\sqrt{16^{2}+12^{2} }[/tex]

r = 20

Answer:

8 cup of blue

12 cup of red

Step-by-step explanation:

The first thing is to calculate how much black paint is produced, assuming that the volumes add up, we have to:

1/2 + 1/3 = 5/6

5/6 cup of paint is produced, I want to know how much I need to produce 20 cups, I divide the value I want by the ideal value, that is, 5/6 and thus I obtain the factor that I require:

20 / (5/6) = 24

Now I multiply by 24 each quantity of blue and red paint

1/2 * 24 = 12

1/3 * 24 = 8

Which means you need 12 cups of red paint and 8 cups of blue paint

Final answer:

To find the percent of students who voted for the athlete, divide the number of students who voted for the athlete by the total number of students, and then multiply by 100. This results in 25% of the students voting for the athlete.

Explanation:

To calculate the percentage of students who voted for the athlete, you would use the formula: part over total, times one hundred, equals percent. In this case, the part is the number of students who voted for the athlete (15), and the total is the combined number of students who voted for the athlete and actor (15 + 45).

So, the calculation would be as follows: (15 / (15 + 45)) x 100 = (15 / 60) x 100 = 0.25 x 100 = 25%. Therefore, 25% of the students voted for the athlete.
