The discount is $1.19 unless you have to round up than it is $1.20. in order to solve this problem you would set up a proportion. So your proportion would be x over 7.99 = 15 over 100. Than you would cross multiply. 7.99*15=119.85. and 100*x=100x. than u divided both sides by a 100. than x= 1.19. which 1.19 is the discount.

Scilla [17]

Answer:

7x^2+28x

Step-by-step explanation:

7x(x+4)\\\\Multiplication\ is\ distributive\ on\ addition\\\\\Rightarrow 7x(x+4)=7(x\times x+x\times 4)\\\\7x(x+4)=7(x^2+4x)\\\\Multiplication\ is\ distributive\ on\ addition\\\\\Rightarrow 7x(x+4)==7\times x^2+7\times 4x\\\\7x(x+4)=7x^2+28x

A researcher drilled a hole in a die and filled it with a lead​ weight, then proceeded to roll it 209 times. The observed freque
ddd [48]

Answer:

Step-by-step explanation:

Given that the observed frequencies for the outcomes as follows:

To check this we can use chi square goodness of fit test.

H_0: equally likely\\H_a: not equally likely

(Two tailed test at 5% significance level)

Assuming equally likely expected observations are found out and then chi square is calculated as (0-E)^2/E

Df = 6-1 =5

Outcome Frequency Expected frequency (Obs-exp)^2/Exp

2 30 34.83333333 0.670653907

4 40 34.83333333 0.766347687

5 23 34.83333333 4.019936204

6 39 34.83333333 0.498405104

   

209 209          7.086124402

p value =0.214

Since p >alpha, we accept null hypothesis

It appears that the  loaded die does not behave differently than a fair​ die at 5% level of significance
