$3.90 -$3.40 =$0.5($0.5/$3.90 )=(x/100)    (  0.5*100)=3.4x                 x =50/3.9                  x=12.8205 percent

(3.10/3.35)-1*-1=0.07462686567 So the percantage decrease to the nearest tenth is 7.4% 3.35 x 0.07462686567= .25 ^ The price difference which is 25cents

What does X equal? 14x+24=18x-32
exis [7]

Answer:

x =14

Step-by-step explanation:

14x+24=18x-32

Subtract 14x from each side

14x-14x+24=18x-14x-32

24 = 4x -32

Add 32 from each side

24+32=4x-32+32

56 = 4x

Divide each side by 4

56/4 = 4x/4

14=x

dimaraw [331]

Answer:

Option C. The real effect is 0.1

Step-by-step explanation:

The complete question is  

You are interested in the psychological implications of high SES. You read a paper that claims that higher social class people behave more unethically. The paper reports a significant difference in the propensity of high and low SES people behaving unethically. The significance level of this study was 0.05, the ratio of true to false effects in this field is 0.35, but the author was anxious to issue a press release and prepare his TED talk, so power is low, at 0.1. The probability that this study reports a real effect is

A. 0.58

B. 0.95

C. 0.1

D. 0.35

E. 0.41

Solution

Ratio of true to false effects i.e T/F = 0.35  

The power of the study indicates the real effect of the study and hence despite the true/false ration being 0.35 and the significance level of study is 0.05, the real effect of the study would be 0.1

Hence option C is correct
