x + y > 15

10x + 5y < 100

we will put it in terms of y

y > 15 - x

and

5y < 100 - 10x

y < 20 - 2x

If the P-value is 0.02, then means that the confidence interval is 2% 98% indeterminable. 95%

hoa [83]

Answer: 98%

Step-by-step explanation:

In statistics , the P-value gives the significance level of the population parameter in the population.

The significance level is denoted by $\alpha.$

Level of confidence is given by :-

$1-\alpha.$

Given : The P-value is 0.02, then the significance level is $\alpha=0.02$ which can be written as 2%.

Then, the confidence interval : $1-0.02=0.98.$ i.e. 98%

Interpolate the median sales price of single family homes sold in June 1995

vovikov84 [41]

Two interpolate you need two points.

Then you assume that there is a linear correlation between those points and so you can derive the value of mid point.

You have a table with median sale prices of single family homes sold for the years from 1975 to 1995.

In this case you have to use the median sale price of single family homes sold at two years: 1994 and 1995.

You assume that the prices of the table are for the end of the year, then the price sold in June 1995 is right in the middle of the sold price in1994 and 1995.

So, the interpolation will give to [price in 1994 + price 1995] / 2 = [140,400 + 141,400] / 2 = 140,900

Answer: 140,900

Can someone please help me factor this

Dmitry_Shevchenko [17]

Answer:

$\huge\boxed{\bf\:1}$

Step-by-step explanation:

$\frac{ x ^ { 2 } -4x+3 }{ x ^ { 2 } -7x+12 } \times \frac{ x ^ { 2 } +2x-24 }{ x ^ { 2 } +5x-6 } ^ { }$

Take $\frac{ x ^ { 2 } -4x+3 }{ x ^ { 2 } -7x+12 }$ & factorise it at first.

$\frac{ x ^ { 2 } -4x+3 }{ x ^ { 2 } -7x+12 } \\= \frac{\left(x-3\right)\left(x-1\right)}{\left(x-4\right)\left(x-3\right)}\\= \frac{x-1}{x-4}$

Now factorise the next set : $\frac{ x ^ { 2 } +2x-24 }{ x ^ { 2 } +5x-6 } ^ { }$ .

$\frac{ x ^ { 2 } +2x-24 }{ x ^ { 2 } +5x-6 } ^ { }\\= \frac{\left(x-4\right)\left(x+6\right)}{\left(x-1\right)\left(x+6\right)}\\= \frac{x-4}{x-1}$

Now, multiply the two simplified results.

$\frac{ x ^ { 2 } -4x+3 }{ x ^ { 2 } -7x+12 } \times \frac{ x ^ { 2 } +2x-24 }{ x ^ { 2 } +5x-6 } ^ { }\\= \frac{x-1}{x-4}\times \frac{x-4}{x-1} \\= \frac{\left(x-1\right)\left(x-4\right)}{\left(x-4\right)\left(x-1\right)} \\= \boxed{\bf\: 1}$
