4.75/100= 0.0475 <--- unit rate

0.0475*225= 10.6875

Round to 10.69. <-- cost for 225 pencils

I hope this helps!

. An independent-measures research study was used to compare two treatment conditions with n=12 participants for each treatment.
Andru [333]

Answer:

Decision rule  is  

Fail to reject the null hypothesis

 The conclusion is  

There is sufficient evidence that indicate that there is a significant difference between the two treatments

Step-by-step explanation:

From the question we are told that  

    The sample size is  n =  12

    The first  mean is  M_1  =  55

    The variance is  s^2_1 =  8

    The second mean is  M_2  =  52

     The second variance is s^2_2 =  4

Let the level of significance be  \alpha  =  0.05

The null hypothesis is  H_o  :  M_1 = M_2

The alternative hypothesis is H_a  :  M_1 \ne M_2

  Generally the test statistics is mathematically

     t = \frac{M_1 - M_2 }{ \sqrt{\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2}} }

=>   t = \frac{55 - 52 }{ \sqrt{\frac{8}{12} +\frac{4}{12 }} }

=>   t = 1.1619

Generally the degree of freedom is mathematically represented as

      df = 12 -1

=>    df = 11

Generally  from the t- distriibution table the critical  value  of  \alpha at a degree of freedom of df = 11  is

    t_{0.05 , 11} =  2.20098516

Here given that the critical value is greater than the t statistics value the

Decision rule  is  

Fail to reject the null hypothesis

 The conclusion is  

There is sufficient evidence that indicate that there is a significant difference between the two treatments

Compare 4:10 and 12:20 using fractions. which ratio is smaller ? how do you know?
andreyandreev [35.5K]
4:10 is smaller because when put into fraction form and making the denominators even, 12:20 comes out to be 6/10

Match the solution set given in inequality notation with the solution set given in interval notation.
sasho [114]

Answer:

x≤7.8  ⇒(-∞;7.8]

x<7.8  ⇒ (-∞;7.8)

x>7.8  ⇒ (7.8; ∞)

x≥7.8  ⇒ [7.8; ∞)

Step-by-step explanation:

Hi, to answer this question we have to analyze each expression:

• x≤7.8

The solution is all the numbers less or equal to 7.8, since it can be equal to 7.8, it includes 7.8 , we have to use closed brackets

(-∞;7.8]

• x<7.8

All the numbers less than 7.8 , it excludes the endpoint , it's an open interval (parenthesis)

(-∞;7.8)

• x>7.8

All the numbers higher than 7.8, open interval (parenthesis)

(7.8; ∞)

• x≥7.8

All the numbers higher or equal to 7.8, closed interval (closed brackets for the endpoint)

[7.8; ∞)

Eight times four is how much less than six squared
andreev551 [17]
8 times four is less than 6 squared by 4, because 8*4 = 32 and 6^2 = 36 then 36-32 = 4.
