P= the car is blue
q= the car is spacious
p^q is true if and only if the car is both blue AND spacious
if the car is not blue, or the car is not spacious, or both then p^q is false

Answer:

<h3>T  F  F F</h3>

Step-by-step explanation:

Let p : "the car is blue."

   q :"the car is spacious."

Conjuction  p^q :

In conjuction If p and q is true then the value of  p^q is true.

But if any statement p or q is false then the value of p^q is false.

When p is true and q is true then the value of  p^q is true.

When p is true  and q is false then the value of p^q is false.

When p is false  and q is true then the value of p^q is false.

When p is false and q is false then the value of p^q is false.

When the car is blue and spacious then  the value of  p^q is true only.

When the  car is not blue but the car is spacious then  the value of  p^q is false.

When the car is blue but  not spacious then  the value of p^q is false.

When the car is not blue nor spacious then the value of p^q is false.

Answer:

The decision rule is  

Reject the null hypothesis  

Step-by-step explanation:

From the question we are told that

    The population mean is \mu =  5.6  \ pounds/inch^2

     The  sample size is  n =  160

      The sample mean is  \=  x =  5.7  \  pounds/ inch^2

     The variance is \sigma ^2 =  0.25

       The level of significance is  \alpha   =  0.01

The null hypothesis is  H_o  :  \mu  =  5.6

The alternative hypothesis is H_a :  \mu > 5.6

Generally the standard deviation is mathematically represented as

           \sigma =  \sqrt{\sigma ^2 }

=>         \sigma =  \sqrt{0.25  }  

=>         \sigma =  0.5  

Generally the test statistics is mathematically represented as

        z =  \frac{\= x  - \mu }{ \frac{\sigma}{\sqrt{n}  } }

=>     z =  \frac{5.7  - 5.6  }{ \frac{0.5 }{\sqrt{ 160 }  } }  

=>     z =  2.53

From the z table  the area under the normal curve to the left corresponding to  2.53   is

        p-value =  P(Z >  2.53 ) =0.0057

From the value obtained we see that the p-value  < \alpha hence

The decision rule is  

Reject the null hypothesis  

The conclusion is  

There is sufficient evidence to conclude that the believe  that the valve performs above the specifications is true

Step-by-step explanation:

Let suppose the attached histogram

a) Total members whose weight 110 = 5

b) Total members whose weight 120 = 4

c) Total members whose weight 130 = 2

d) Total members whose weight 140 = 0

e) Total members whose weight 150 = 5

f) Total members whose weight 160 = 0

g) Total members whose weight 170 = 4

Total member = a+b+c+d+e+f+g=5+4+2+0+5+0+4=20 member

A histogram is a statistical graphical representation of data with the help of bars with different heights.

−px+r=−8x − 2, x=?<br> now i have to do this problem, and i dont know how, help?
Taya2010 [7]

-px + r = - 8x - 2

-px + r + 8x +2 = 0

-px +8x = -r -2

x(8-p) = -r -2

x= \frac{8-p}{-r-2} =

\frac{8-p}{-r-2}
