Answer:

<u>Entran 9 cuadrados en la hoja</u>

<u>Se puden hacer 10 tarejtas por que hay un cuadradro de 10*10 extra.</u>

Step-by-step explanation:

El area de la hoja sera:

A_{Hoja}=30*30=900 \:cm^{2}

Ahora el area de cada tarjeta es:

A_{tarjeta}=10*10=100\: cm^{2}

Para determinar cuantos tarjetas entran en la hoja debemos vidivir las aras encontradas arriba:

\frac{A_{Hoja}}{A_{tarjeta}}=\frac{900}{100}=9

<u />

<u>Entonces entran 9 cuadrados en la hoja</u>

<u>Se puden hacer 10 tarejtas por que hay un cuadradro de 10*10 extra.</u>

<u />

Espero te haya sido de ayuda!

The scale on a map is 3 inches : 4 miles. How far apart are two cities that are 9 inches apart on the map?
harkovskaia [24]

Answer:

Distance between two cities that are 9 inches apart on the map is 11.97 miles (12 miles)

Step-by-step explanation:

As it is given in the question scaled distance on a map is 3 inches = 4 miles.

Now we have to calculate how many miles in 1 inches on the map = 4÷3

                                                                                      = 1.33miles

Now we get the value of 1 inches on the map = 1.33 miles

9 inches = 1.33 × 9 = 11.97 miles ( Probably close to 12 miles if allowing for changing elevations in the distance)

In elementary school we used to refer to this as a ratio problem; two equal ratios with one containing unknown as :

X/C = A/B

X miles / 9 inches = 4 miles / 3 inches

X = 9 (4÷3)

X = 9×1.33

X = 11.97

=12 miles

Consider the basis B of R2 consisting of vectors
adelina 88 [10]

The idea is to find a linear combination a_1(5, -6) + a_2(-2, -2) = (-6, 2) It boils down to a system of equations: Take the augmented matrix:

<span>[<span><span>5<span>−6</span></span><span><span>−2</span><span>−2</span></span><span><span>−6</span>2</span></span>]</span> Reduced form: <span>[<span><span>10</span><span>01</span><span><span>−<span>811</span></span><span>1311</span></span></span>]</span> -(8/11)*(5, -6) + (13/11)*(-2, -2) = (-6, 2)

In your own words, explain the Normal Distribution and provide a real world example.
elena-14-01-66 [18.8K]

Answer:

The Normal distribution is a continuous probability distribution with possible values all the reals. Some properties of this distribution are:

Is symmetrical and bell shaped no matter the parameters used. Usually if X is a random variable normally distributed we write this like that:

X \sim N(\mu , \sigma)

The two parameters are:

\mu who represent the mean and is on the center of the distribution

\sigma who represent the standard deviation  

One particular case is the normal standard distribution denoted by:

Z \sim N(0,1)

Example: Usually this distribution is used to model almost all the practical things in the life one of the examples is when we can model the scores of a test. Usually the distribution for this variable is normally distributed and we can find quantiles and probabilities associated

The sum of the areas of two square plots of land is 2650 m^2 and the difference of their areas is 1400 m^2. Find the length of a
Sav [38]

Answer:

The length of one plot is 45m & the other length is 25m

Step-by-step explanation:

Let length one sq. plot = x length other sq. plot = y

area of square = length²

x² + y² = 2650 -----(1)

x² - y² = 1400 ------(2)

(1)+(2)

2x² = 4050

x² = 2025

x = 45

subx²=2025into(1)

2025 + y² = 2650

y² = 625

y = 25
