Answer:

n= 1500representan la muestra aleatoria seleccionada

X= 1188indican el número de macetas que tenían suelo desnudo (sin vegetación

\hat p=\frac{X}{n}

Y al reemplazar obtuvimos:

\hat p=\frac{1188}{1500}= 0.792

Por lo tanto, la proporción de lugares con suelo desnudo en esta muestra es 0.792

Step-by-step explanation:

Aquí está la información proporcionada en el problema:

n= 1500representan la muestra aleatoria seleccionada

X= 1188representan el número de macetas que tenían suelo desnudo (sin vegetación)

Y en este caso, si queremos encontrar la proporción de la muestra de lugares con suelo desnudo, podemos usar esta fórmula:

\hat p=\frac{X}{n}

Y al sustituir obtenemos:

\hat p=\frac{1188}{1500}= 0.792

Por lo tanto, la proporción de lugares con suelo desnudo en esta muestra es 0.792

762,508 expanded form using exponents
Svet_ta [12734]

762,508 expressed in expanded form with exponents is:

7 \times 10^5 + 6 \times 10^4 + 2 \times 10^3 + 5 \times 10^2 +0 \times 10^1 + 8 \times 10^0

Solution:

We need to write 762,508 using expanded notation with exponents.

Expanded form indicates how to represent numbers to highlight the individual digit values.

Displaying 762508 in Expanded format

Let's determine the positional values of each digit:

The concept of place value signifies the worth assigned to each digit based on its location.

For 7, the place value is 700,000

In 762508, the digit 7 is located in the hundred-thousands position.

For 6, the place value is 60,000

In 762508, the digit 6 occupies the ten-thousands position.

For 2, the place value is 2,000

In 762508, 2 is in the thousands position.

For 5, the place value is 500

In 762508, 5 is placed in the hundreds position.

For 0, the place value is 0 x 10 = 0

In 762508, 0 is found in the tens position.

For 8, the place value is 8

In 762508, 8 is positioned in the units place.

Thus, the expanded form is:

700,000 + 60,000 + 2,000 + 500 + 0 + 8

Expressed with exponents, it can be written as:

7 \times 10^5 + 6 \times 10^4 + 2 \times 10^3 + 5 \times 10^2 +0 \times 10^1 + 8 \times 10^0

Leona [12618]

Answer:

Step-by-step explanation:

According to the attached figure, Jaxon is positioned 10 blocks east and 5 blocks north.

Thus, Jaxon's x-coordinates are 10 units, while the y-coordinates are 5 units.

Therefore, the coordinates are given by (10,5)

Similarly, Isaac's coordinates are determined based on his distances towards the west and south.

Hence, the x-coordinates equal 8 units and the y-coordinates equal 15 units.

Thus, Isaac’s coordinates are depicted as (-8,-15).

Inessa [12570]

Answer:

£700,000

Detailed explanation:

Let x represent the original price of the house. Keeping in mind that

7%=\frac{7}{100}

Upon a 7% increase in the house value, it is now set at £749,000. We can express this as

x+\frac{7}{100}x = 749,000

We can solve for x now:

x+\frac{7x}{100}=749,000\\100x + 7x = 74,900,000\\107 x = 74,900,000\\x=\frac{74,900,000}{107}=700,000

Thus, the initial valuation of the house was

£700,000
