Answer:

6) 6\sqrt{2}

9) 40

10) \frac{5\sqrt{2} }{2}

11) 13

Step-by-step explanation:

6)A right triangle rule: if 2 legs are equal, the hypotenuse is the length of that leg*\sqrt{2}

9) Pythagorean Theorem

a^{2} +b^{2} =c^{2}

We know the hypotenuse (41) so we substitute that for c and 9 for b now we need to find a

\sqrt{41^{2}-9^{2}  } which gives us 40

10) same with #6 but we do the opposite. SInce we have the hypotenuse, we can divide that by \sqrt{2} because we know that if 2 legs are equal, the hypotenuse is multiplied by \sqrt{2}. Multiply the numerator and denominator by \sqrt{2} because we can't have a square root in the denominator.

11) like #9 we have the a and b but we need to find c

a=5 b=12 c=r

so \sqrt{5^{2}+12^{2}  } which gives us 13

<h2>6TH PART -> </h2>

<h3>GIVEN </h3>
  1. RIGHT ANGLE SO ITS A RIGHT ANGLED TRIANGLE SO WE CAN USE PYTHAGOUS THEOREM
  2. TWO SIDES ( BASE AND PERPENDICULAR) R EQUAL TO 6

<h3>SOLUTION-></h3>

{h}^{2}  =  {p}^{2}  +  {b}^{2}

{c}^{2}  =  {6}^{2}  +  {6}^{2}  \\  {c}^{2}  = 36 + 36 \\ c =  \sqrt{2( {6}^{2} )}  \\ c =  \sqrt{2}{\sqrt{ {6}^{{2}} } } \\ c = 6 \sqrt{2}  \:  \:  \: ans

<h2>9TH PART:- </h2>

<h3>GIVEN</h3>

  1. RIGHT ANGLE SO ITS A RIGHT ANGLED TRIANGLE SO WE CAN USE PYTHAGOUS THEOREM
  2. BASE = 9
  3. HYPOTENUSE= 41

SOLUTION->

{h}^{2}  =  {p}^{2}  +  {b}^{2}

{41}^{2}  =  {x}^{2}  +  {9}^{2}  \\ 1681 =  {x}^{2}  + 81 \\ 1681 - 81 =  {x}^{2}  \\ 1600 =  {x}^{2}  \\ x =  \sqrt{40 \times 40}  \\ x = 40 \:  \:  \: ans

<h3>SOLUTION-></h3>

{h}^{2}  =  {p}^{2}  +  {b}^{2}

{5}^{2}  =  {s}^{2} +   {s}^{2}  \\ 25 = 2 {s}^{2}  \\ 12.5 =  {s}^{2}  \\  \sqrt{12.5}  = s \\ 3.5 = s \:  \:  \: ans

A random sample of 9 wheels of cheese yielded the following weights in pounds has a sample mean of 20.90 and a sample variance o
Ronch [10]

Answer:

2.002 \leq \sigma^2 \leq 11.365

Step-by-step explanation:

1) Data given and notation

s represent the sample standard deviation

s^2 represent the sample variance

n=9 the sample size

Confidence=90% or 0.90

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population mean or variance lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.

The Chi Square distribution is the distribution of the sum of squared standard normal deviates .

2) Calculating the confidence interval

The confidence interval for the population variance is given by the following formula:

\frac{(n-1)s^2}{\chi^2_{\alpha/2}} \leq \sigma \frac{(n-1)s^2}{\chi^2_{1-\alpha/2}}

On this case we need to find the sample standard deviation with the following formula:

s=sqrt{\frac{\sum_{i=1}^9 (x_i -\bar x)^2}{n-1}}&#10;The sample variance given was [tex]s^2=3.45

The next step would be calculate the critical values. First we need to calculate the degrees of freedom given by:

df=n-1=9-1=8

Since the Confidence is 0.90 or 90%, the value of \alpha=0.1 and \alpha/2 =0.05, and we can use excel, a calculator or a table to find the critical values.  

The excel commands would be: "=CHISQ.INV(0.05,8)" "=CHISQ.INV(0.95,8)". so for this case the critical values are:

\chi^2_{\alpha/2}=15.507

\chi^2_{1- \alpha/2}=2.732

And replacing into the formula for the interval we got:

\frac{(9)(3.45)}{15.507} \leq \sigma \frac{(9)(3.45)}{2.732}

2.002 \leq \sigma^2 \leq 11.365

6x + 7y = 1<br> 8x – 3y = 25<br> Solve me fast explainly
Elenna [48]

Answer:

{x,y} = {89/37,-71/37}

Step-by-step explanation:

 8x = 3y + 25

 [2]    x = 3y/8 + 25/8

Plug this in for variable  x  in equation [1]

  [1]    6•(3y/8+25/8) + 7y = 1

  [1]    37y/4 = -71/4

  [1]    37y = -71

Solve equation [1] for the variable  y  

  [1]    37y = - 71

  [1]    y = - 71/37

By now we know this much :

   x = 3y/8+25/8

   y = -71/37

Use the  y  value to solve for  x  

   x = (3/8)(-71/37)+25/8 = 89/37
