51 square meters because if you divide the parallelogram into a triangle and a rectangle it would be 7 times 7 plus 2 times (2×.5) which is 49 plus 2

Which expression represent the product of x3 + 2x - 1 and x4 - x3 + 3

Alborosie

Answer:

x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.

Step-by-step explanation:

(x3 + 2x - 1) (x4 - x3 + 3)

= x^7 - x^6 + 3x^3 + 2x^6 - 2x^4 + 6x - x^4 + x^3 - 3

= x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.

Suppose the selling price of homes is skewed right with a mean of 350,000 and a standard deviation of 160000 If we record the se

lys-0071 [83]

Answer:

The distribution will be approximately normal, with mean 350,000 and standard deviation 25,298.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Population:

Suppose the selling price of homes is skewed right with a mean of 350,000 and a standard deviation of 160000

Sample of 40

Shape approximately normal

Mean 350000

Standard deviation $s = \frac{160000}{\sqrt{40}} = 25298$

The distribution will be approximately normal, with mean 350,000 and standard deviation 25,298.

pochemuha

The point (2, -5) would not be one of the correct vertices of the reflected shape.

When we reflected a shape across the line y=x, we just replace the x's with y's and y's with x's.

Our new points are (5, 2) (4, 6) and (3, 3). None of the points contain negative numbers.

(x/6)-10=2<br> please help me find x

Ymorist [56]

Answer:

$x = 72$

Step-by-step explanation:

$( \frac{x}{6}) - 10 = 2 \\ ( \frac{x}{6} ) = 2 + 10 \\ \frac{x}{6} = 12 \\ x = 12 \times 6 \\ x = 72$
