4n - 7 = 29

That's the equation :)

You can use any variable; doesn't have to be n.

If you want to solve for the variable, then it would be 5.5

Answer:

7-4*x = 29

Step-by-step explanation:

All you have to do is take 7 subtract it by 4 then times that by x (random number) and the =29 and just put that into an equation. Please tell me if that doesn't make sense lol.

The useful life of a radial tire is normally distributed with a mean of 30,000 miles and a standard deviation of 5000 miles. The

otez555 [7]

Answer:

empirical rule: 81.5%

table or calculator: 81.9%

Step-by-step explanation:

The lower limit of the life range of interest has a z-score of ...

z = (x -μ)/σ = (20,000 -30,000)/5,000 = -2

The upper limit has a z-score of ...

z = (35,000 -30,000)/5,000 = 1

Empirical rule solution

The empirical rule tells you that 95% of the distribution lies within 2 standard deviations of the mean, so (100% -95%)/2 = 2.5% lie below z = -2. It also tells you 68% lie within 1 standard deviation of the mean, so (100% -68%)/2 = 16% lie above z = 1.

The fraction that lies within -2 to 1 standard deviations of the means is thus ...

(100% -2.5% -16%) = 81.5%

The probability the tire has a life in the desired range is about 81.5%.

Calculator solution

A probability calculator for the Normal distribution tells you that ...

P(-2 < z < 1) ≈ 0.8185946

The probability the tire has a life in the desired range is about 81.9%.

The Dallas Morning News is running a series of articles to see if the residents of Dallas still support the Mayor’s decision to

erastova [34]

Answer and Step-by-step explanation:

A+B only 10% = $1250 / 2 \times 1-2$ = 0

$1250 / 76=x 1.6 \pm(+1=2.5 \%) 90 \% \text { vote }=1226$

95%=1302

99% = 1377

5% = 1188

2.5% = 1169

A= deduct this from sample size B it is usually 5 of the vote% so in comparison would not hinder the negative we deduct 1 from the 5%. B. Margin of error is 2.5% deduction comparison was Mayor was asking for a negative outcome with a positive vote. which is biased alone. Loss of confidence due to margins.
