Suppose you pick a marble from a box containing five red and seven blue marbles. You record the color and put the marble back in the box. What is the probability of getting a red marble both times if you do this twice?.

The sidewalk around a lake is 9/10 mile long. You walk 3 laps Around the lake in the morning and 2 laps in the evening. Your friend walks the same total distance as you on a 3/2 mile track.

Given that

To find

So, according to the question

we have,

                                                     = (9 ×5)/10

                                                     = 4.5 miles.

Now, from question

So, Total laps walk by your friend

             = ( Total distance walk by you)/(Total length of your friends track)

             = [tex]\frac{4.5}{(\frac{3}{2}) }[/tex]

             = [tex]\frac{4.5\times 2}{3}[/tex]

By using Pythagoras theorem,

where a & b = legs of triangle and c = hypotenuse

Hence:

The actual area of the care park in hectares is 18.75

As per the known fact, ratio of measurement on scale is equal to the ratio of measurement in real. So, writing the equation first -

Area of car park = 3 cm²

Keep the value of 1 cm in the above mentioned equation.

Area of car park = 3 × (250)²

Taking square

Area of car park = 3 × 62,500

Performing multiplication

Area of car park = 1,87,500 m²

Converting the area in hectares

10,000 m² = 1 hectare

1,87,500 m² = (1 ÷ 10,000) × 1,87,500

1,87,500 m² = 18.75 hectares.

Therefore, the actual area of the care park is 18.75 hectares.

We need to know about linear and proportional relationship to solve this problem. Statement 2 is true, the description shows a linear relationship and a proportional relationship.

Linear relationship is a relationship between two variables where if one increases the other increases or if one decreases the other decreases. The varibales in a linear relationship form a straight line on graph. Proportional relationship is the relationship between two variables where the ratio between pairs of different data always remains constant. In the given question, a 12 ounce cup costs $1.97, a 16 ounce cup costs $2.62 and a 20 ounce cup costs $3.27. The price of each cup increases with increase in capacity of the cup, so we can say that the cup capacity and price have a linear relationship. The ratio between each pair can be given by

12/1.97=6.10

16/2.62=6.10

20/3.27=6.10

The ratios between every pair is same, so it is a proportional relationship.

Thus we found that the description shows a linear relationship and a proportional relationship between the cup capacity and it's price, statement 2 is the right option.

Answer: The problem asks to solve for x. Equation B gives you the value of y, y = 2, so you can substitute 2 into Equation A for y.

Step-by-step explanation:

The value of the expression log₃9 is 2.

The logarithmic function is the inverse of the exponential function. This means that the logarithm of a given number, say x, is the exponent to which another fixed number that is the base b, must be raised, so as to produce that number x.

Log a to the base b can be written as- log a/ log b.

Moreover, log [tex]a^{k}[/tex]= k log a, for all non negative values of a

Here, we are given a logarithmic expression- log₃9

We can expand this as-

log₃9 = log 9/ log 3

= log [tex]3^{2}[/tex]/ log 3

= 2 log 3/ log 3

= 2

Thus, the value of log₃9 is 2.

De acuerdo a la información se puede inferir que su hijo nació en el año 22 antes de Cristo.

Una recta numérica es una herramienta gráfica de las matemáticas que nos sirve para ubicar números positivos y negativos en un gráfico con el objetivo de organizarlos con respecto al número cero.

Las líneas de tiempo con fechas Antes y Después de Cristo se pueden asociar a una recta numérica debido a que los años Antes de Cristo se ubican en la parte negativa de la gráfica (a la izquierda del cero) y los número Después de Cristo se ubican en la parte positiva (a la derecha del cero).

Para identificar el año de nacimiento del hijo debemos tener en cuenta que las fechas que se ubican en la zona negativa de la recta numérica aumentan de forma invertida, es decir que si su hijo nació 28 años después de ella se debe restar este número a su fecha de nacimiento como se muestra a continuación:

50 - 28 = 22

Entonces, el año de nacimiento de su hijo sería el año 22 Antes de Cristo.

For logarithmic equation 1/2 log x + log 4 = 2, the value of x is 34,040.25

Step 1: Using exponentiation principles, isolate a logarithmic expression (with the same base) on both sides of the equation.

Step 2: balance the arguments.

Step 3: Solve the resultant equation.

Step 4: Double-check your answers.

Given,

1/2 log x + log 4 = 2

log x^(1/2) + log 4 = 2

using logₐ(m.n) = logₐ(m) + logₐ(n)

log e (4 (x^1/2)) = 2

e² = 4x^(1/2)

7.38 = 4√x

Squaring on both sides -

54.4644 = 16x

x = 54.4644 / 16

x = 34,040.25

When we have captured (t*s)(x), that is as equivalent as t(s(x)). To solve this, we take the important role of s(x), x-7, and call in an alternative for it in for every x in t(x). Instead of 4x², we have 4(x-7)²; instead of -x, we have -(x-7). This gives us 4(x-7)²-(x-7)+3.

Considering the definition of an equation and the way to solve it, the correct answer is the third option: Cadence baked 21 cupcakes on Monday.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns.

The members of an equation are each of the expressions that appear on both sides of the equal sign.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Being "x" the number of cupcakes baked by Cadence on Monday, and knowing that:

the equation in this case is:

3 + 2x= 45

Solving:

2x= 45 -3
